You've got the lift kit, the wheels are picked out, and now it's decision time: 35-inch tires or 37-inch tires? It's the most debated question in the lifted truck community, and there's no universal right answer. The best choice depends on your truck, your budget, how you drive, and what you want your build to accomplish.

At American Fusion Wheels in Shawnee, Kansas, we've helped hundreds of truck owners make this exact decision. We've seen the builds where 35s were perfect and the builds where only 37s would do. In this comprehensive comparison, we'll break down every factor — lift requirements, cost, fuel economy, off-road performance, daily drivability, and more — so you can make a confident choice.

The Great Tire Size Debate

Before we dive into specifics, let's establish what we're actually comparing. When we say "35-inch tire," we're referring to tires with an approximate overall diameter of 35 inches — common sizes include 35x12.50R17, 35x12.50R20, and 315/70R17. A "37-inch tire" has an approximate diameter of 37 inches, with popular sizes like 37x12.50R17, 37x13.50R20, and 37x12.50R22.

That two-inch difference in diameter translates to one inch of additional ground clearance (since only the bottom half of the tire adds clearance). One inch might not sound like much, but in the off-road world, that inch can mean the difference between clearing an obstacle cleanly or dragging your differential across a rock. On the street, that extra inch changes the visual proportions of your truck, affects speedometer accuracy, and impacts drivetrain wear patterns.

Let's examine both options in detail so you can see the full picture. For more sizing information, check out our tire size comparison guide.

35-Inch Tires: The Sweet Spot

There's a reason the 35-inch tire is the most popular size in the lifted truck world. It hits a balance point that works for the vast majority of truck owners. Here's what you need to know:

Lift Requirements for 35s

Most half-ton trucks need a 3 to 4-inch suspension lift to properly clear 35-inch tires. Some vehicles with generous wheel wells — like the Jeep Wrangler JL — can get away with a 2.5-inch lift. You'll likely need minor fender trimming on most trucks, and aftermarket upper control arms (UCAs) are recommended to restore proper alignment geometry.

Cost

A set of four quality 35-inch all-terrain tires typically runs $1,200 to $1,800. Mud-terrains in this size range from $1,400 to $2,200. Combined with a mid-range suspension lift kit ($1,500–$3,500 installed), wheels ($1,200–$2,400 for a set of four), and installation, a complete 35-inch build usually costs $5,000 to $9,000 all-in.

Performance Characteristics

• Fuel economy impact: Expect to lose 2–3 MPG compared to stock tires. A truck that got 18 MPG stock will typically see 15–16 MPG on 35s.
• Acceleration: Noticeable but not dramatic reduction. Your truck's stock gearing can generally handle 35s, though re-gearing to 4.56 ratios improves throttle response.
• Braking: Slightly increased stopping distances. Stock brakes are adequate but work harder.
• Highway comfort: Very manageable. Quality 35-inch AT tires are quiet and comfortable at highway speeds.
• Off-road capability: Significant improvement over stock. You gain approximately 1.5 inches of ground clearance and substantially more traction from the larger contact patch.

Pros of 35-Inch Tires

• Moderate lift kit required — lower cost of entry
• Stock drivetrain can usually handle the load (no mandatory re-gearing)
• Wide selection of tire brands and tread patterns available
• Manageable fuel economy impact
• Easy to find replacements at any tire shop in an emergency
• Good balance of off-road capability and daily drivability
• Lower overall weight means less stress on brakes, bearings, and suspension

Cons of 35-Inch Tires

• May not provide enough clearance for serious rock crawling
• Can look slightly undersized on three-quarter-ton and one-ton trucks
• Still requires some modifications (trimming, UCAs) on many trucks
• Not the most impressive visual statement at truck meets

37-Inch Tires: Maximum Capability

When 35s aren't enough — whether for trail clearance, visual impact, or bragging rights — 37-inch tires enter the conversation. This is where builds get serious, both in capability and investment.

Lift Requirements for 37s

Plan on a minimum 6-inch suspension lift for most trucks. Some platforms, like the Jeep Wrangler on 17-inch wheels with high-clearance fenders, can fit 37s on a 3.5–4 inch lift. But for pickups like the F-150, Silverado, and Ram, 6 inches is the starting point. You'll definitely need aftermarket upper control arms, and fender trimming or aftermarket fenders are almost always required.

Cost

A set of four quality 37-inch tires runs $1,800 to $2,800 for all-terrains and $2,000 to $3,200 for mud-terrains. The lift kit investment is higher — quality 6-inch kits range from $3,000 to $6,000 installed. Add wheels, re-gearing (almost mandatory at this size), and miscellaneous parts, and a complete 37-inch build typically costs $9,000 to $16,000+ all-in.

Performance Characteristics

• Fuel economy impact: Expect to lose 3–5 MPG compared to stock. That same truck getting 18 MPG stock might see 13–15 MPG on 37s, depending on gearing and tire type.
• Acceleration: Noticeably sluggish without re-gearing. With proper 4.56 or 4.88 gears installed, throttle response is restored to near-stock feel.
• Braking: Measurably increased stopping distances. Upgraded brakes (larger rotors, high-performance pads) are strongly recommended.
• Highway comfort: Depends heavily on tire choice. Quality AT tires in 37-inch sizes can be surprisingly comfortable. MT tires will generate noticeable drone.
• Off-road capability: Dramatic improvement. You gain approximately 2.5 inches of ground clearance over stock, and the massive contact patch provides incredible traction in every condition.

Pros of 37-Inch Tires

• Maximum ground clearance for serious off-road use
• Commanding visual presence — your truck will stand out anywhere
• Huge contact patch for ultimate traction
• Better obstacle clearance at approach, departure, and breakover angles
• Ideal for heavy-duty trucks (2500/3500 series) that have the power and braking to support them
• Higher resale value on well-built rigs

Cons of 37-Inch Tires

• Significantly higher build cost (lift, gears, brakes, tires)
• Substantial fuel economy penalty
• Re-gearing is virtually mandatory ($1,500–$2,500)
• Increased wear on wheel bearings, ball joints, and CV joints
• Limited tire selection compared to 35-inch sizes
• Harder to find emergency replacements on road trips
• Parking in tight spaces and garages becomes challenging
• Heavier tires stress brakes more — upgraded braking systems recommended

Lift Kit Requirements: 35s vs 37s by Vehicle

Every truck platform is different. Here's a quick reference for the most popular vehicles we see at our lift kit shop:

Ford F-150 (2015+)

• For 35s: 4-inch suspension lift, aftermarket UCAs, minor front fender trimming. 17 or 18-inch wheels with 0 to -12mm offset recommended.
• For 37s: 6-inch suspension lift, aftermarket UCAs, fender trimming or aftermarket fenders, re-gearing to 4.56. Crash bars may need modification.

Chevrolet Silverado / GMC Sierra 1500 (2019+)

• For 35s: 4-inch suspension lift with UCAs. Factory fender liners need trimming. Stamped steel front bumpers may require slight modification.
• For 37s: 6 to 8-inch suspension lift, UCAs, fender trimming, re-gearing to 4.56 or 4.88. CV axle angles become a concern — quality lifts with diff drop kits help.

Ram 1500 (2019+ DT)

• For 35s: 3.5 to 4-inch suspension lift. The Ram's air suspension models (if equipped) complicate lifting. Factory UCAs limit caster — aftermarket UCAs strongly recommended.
• For 37s: 6-inch suspension lift, aftermarket UCAs, re-gearing, and likely aftermarket front bumper for proper clearance. The coil-spring rear makes ride quality surprisingly good even on 37s.

Jeep Wrangler JL / JLU (2018+)

• For 35s: 2.5-inch suspension lift is usually sufficient on 17-inch wheels. The Rubicon model may fit 35s with a leveling kit and minor trimming.
• For 37s: 3.5 to 4-inch lift on 17-inch wheels. Fender flares may need replacement with high-clearance options. Re-gearing to 4.88 is recommended (Rubicon models already have 4.10 gears).

Ford Bronco (2021+)

• For 35s: The Sasquatch package comes with 35s from the factory. Non-Sasquatch models need a 2 to 3-inch lift and possibly different fender flares.
• For 37s: 3 to 4-inch lift, aftermarket fender flares, and re-gearing for non-Sasquatch models. Sasquatch models benefit from aftermarket UCAs and minor trimming.

Toyota Tacoma (2016+)

• For 35s: 3-inch suspension lift, cab mount chop (CMC), and aftermarket UCAs. The Tacoma's smaller wheel wells make fitting 35s more involved than on full-size trucks.
• For 37s: Extremely challenging. Requires 6+ inch lift, significant body modification, re-gearing, and aftermarket axles in some cases. Not commonly recommended for Tacomas.

Cost Comparison: Total Build for 35s vs 37s

Let's lay out the full financial picture. These estimates assume quality (not budget, not top-shelf) components and professional installation at a shop like American Fusion Wheels:

Component	35-Inch Build	37-Inch Build
Tires (set of 4)	$1,200 – $2,000	$1,800 – $3,000
Wheels (set of 4)	$1,200 – $2,400	$1,200 – $2,400
Lift Kit (parts + labor)	$1,500 – $3,500	$3,000 – $6,000
Aftermarket UCAs	$400 – $800	$400 – $800
Re-gearing	Optional ($1,500 – $2,500)	Recommended ($1,500 – $2,500)
Trimming / Body Work	$100 – $300	$200 – $800
Alignment	$150 – $250	$150 – $250
Road Force Balancing	$100 – $200	$100 – $200
Estimated Total	$5,000 – $9,500	$9,000 – $16,000+

The 37-inch build costs roughly 60–80% more than a comparable 35-inch build. That's a significant financial commitment, and it's important to factor in the ongoing costs too — 37-inch tires cost more to replace, and the increased wear on drivetrain components means higher maintenance costs over time.

Real-World Driving Differences

Numbers on paper are one thing, but what does the everyday driving experience actually feel like? Here's what our customers report after living with their builds:

Fuel Economy (MPG)

This is often the deciding factor for daily drivers. On a typical half-ton truck:

• Stock tires: 17–20 MPG highway
• 35-inch AT tires: 14–17 MPG highway (2–3 MPG loss)
• 37-inch AT tires: 12–15 MPG highway (3–5 MPG loss)
• 37-inch MT tires: 11–14 MPG highway (4–6 MPG loss)

Over 15,000 miles per year at $3.50/gallon, the difference between 35s and 37s costs an extra $300–$700 annually in fuel. Over a typical 5-year ownership period, that's $1,500–$3,500 in additional fuel costs alone.

Highway Comfort

35-inch tires, especially quality all-terrain options, are remarkably comfortable on the highway. Most passengers wouldn't notice a significant difference from stock tires on a smooth road. 37-inch tires introduce more unsprung weight, which can make the ride feel slightly busier over small imperfections. With proper Road Force Balancing, both sizes can be smooth and vibration-free.

Towing Capability

Larger tires reduce your effective towing capacity. The increased rolling resistance and altered gearing put more strain on the drivetrain. If you tow regularly:

• 35s with stock gears: Manageable for moderate loads; re-gearing helps significantly
• 37s: Re-gearing is essential for safe, effective towing. Without it, transmission temperatures will climb and the truck will struggle on grades

Parking and Maneuverability

A truck on 37s with a 6-inch lift is significantly taller and wider than stock. Parking garages become stressful (many have 6'6" clearance limits — measure your truck). Drive-throughs may be tight. Neighborhood parking requires more awareness. 35s on a 4-inch lift keep the truck within a more manageable envelope for daily urban and suburban driving in the Kansas City metro area.

When to Choose 35-Inch Tires

35-inch tires are the right choice when:

• Your truck is your primary daily driver
• You want a significant visual and capability upgrade without breaking the bank
• You tow or haul regularly and can't afford to lose too much efficiency
• You go off-road recreationally — trails, forest roads, hunting land, camping
• You want maximum tire selection from every major brand
• Your vehicle is a half-ton truck or mid-size (Tacoma, Ranger, Colorado)
• You value practicality alongside aesthetics
• Your budget for the total build is $5,000 to $10,000

For the majority of lifted truck owners in the Kansas City area, 35-inch tires represent the ideal balance. They look great, perform well off-road, and don't require a complete drivetrain overhaul to live with daily.

When to Choose 37-Inch Tires

37-inch tires make sense when:

• You have a dedicated off-road vehicle or a truck that isn't your only car
• You compete in off-road events or tackle serious trails regularly (Moab, Ouachita, Ozark rock crawling)
• You're building a three-quarter-ton or one-ton truck that has the power, braking, and frame to support them properly
• You want maximum visual impact and have the budget to do it right
• You're willing to invest in supporting modifications (re-gearing, upgraded brakes, reinforced drivetrain components)
• You understand and accept the higher ongoing costs (fuel, tire replacement, maintenance)
• Your budget for the total build is $10,000 to $18,000+

If you're building a show truck, a serious off-road machine, or a heavy-duty rig that demands presence and capability, 37-inch tires are worth every penny.

Frequently Asked Questions

Will 37-inch tires fit on a stock truck?

No. No current production truck (aside from specialty vehicles like the Ram TRX with modifications) can fit 37-inch tires without a lift kit and other modifications. Even trucks with factory leveling kits lack the clearance needed for 37s at full steering lock and suspension compression. A proper suspension lift, fender trimming, and potentially aftermarket fenders are required.

Is it worth re-gearing for 35-inch tires?

It depends on your truck's factory gear ratio. If your truck came with 3.21 or 3.31 gears, re-gearing to 4.10 or 4.30 will dramatically improve throttle response, towing ability, and transmission behavior with 35s. If your truck already has 3.73 gears (common on tow packages), you can live with 35s on stock gears, though 4.56 will still feel better. For 37s, re-gearing to 4.56 or 4.88 is essentially mandatory regardless of factory gearing.

Do 35-inch or 37-inch tires affect my warranty?

This is a nuanced question. In general, the Magnuson-Moss Warranty Act prevents dealers from voiding your entire warranty due to aftermarket modifications. However, if a failure can be directly attributed to your modifications (e.g., a wheel bearing fails prematurely due to heavier tires), that specific repair may not be covered. Some manufacturers, like Ford with their Tremor and Raptor packages, are more modification-friendly. We recommend discussing your plans with your dealership's service advisor before starting your build.

Can I switch between 35s and 37s later?

If you build for 37s (6-inch lift, proper gearing), you can absolutely run 35s on that setup — they'll just look slightly smaller under the fenders. Going the other direction is harder. If you build for 35s (4-inch lift), you cannot simply swap to 37s without upgrading your lift kit and likely re-gearing. This is why some customers choose to build for 37s from the start, even if they initially mount 35-inch tires — it leaves room for growth.
