Key Differences In Performance
To see the real-world impact, here’s a direct comparison:
| Feature | 35-Inch Tires | 37-Inch Tires |
|---|---|---|
| Weight (each) | ~60 lbs | ~75 lbs |
| Lift Required | 2.5–3.5″ | 4–6″ |
| Stock Axles | Often OK | Upgrades Needed |
| Fuel Economy Loss | 1–2 mpg | 2–4 mpg |
What To Consider Before Upgrading
Gearing And Drivetrain
Bigger tires mean lower gear ratios are often needed. Stock gears may struggle with 37s, especially on hills or when towing.
Suspension And Steering
A 4-inch lift for 37s changes your Jeep’s center of gravity. Upgrades like adjustable control arms and track bars help maintain stability.
Axle Strength
Factory axles may bend or break with 37s. Dana 44 or stronger axles are highly recommended.
Braking Performance
Heavier tires take longer to stop. Consider upgrading to bigger brake kits if you pick 37s.
Real-world Example
A 2020 Jeep Wrangler Rubicon on 35s can run most trails in Moab without issue, while 37s make the hardest obstacles easy but need re-gearing and axle upgrades. On highways, the 35s feel smoother and use less fuel.
Cost Comparison
Here’s a look at the price difference, including essential upgrades:
| Item | 35-Inch Setup | 37-Inch Setup |
|---|---|---|
| Tires (set of 5) | $1,300 | $1,900 |
| Lift Kit | $1,000 | $1,700 |
| Gearing | Optional | $1,500 |
