17 vs 18-Inch Wheels on a Jeep: Which Is Better for Bigger Tires?
Guide · Updated October 27, 2026
Most Jeep owners fitting 35s or 37s choose 17-inch wheels, but 18s and 20s are popular for street looks. Here is how wheel size changes the tire you end up with.
Sidewall and ride
- Smaller wheels mean taller sidewalls for the same tire diameter.
- Taller sidewalls cushion bumps and let you air down further off-road.
- Larger wheels give sharper steering on pavement but a firmer ride.
Tire choice and cost
- 17 inches has the widest choice of 33, 35 and 37-inch all-terrain and mud-terrain tires.
- 18 and 20-inch off-road tires are fewer and often cost more.
Brake clearance
- Most JL, JK and Gladiator brakes clear 17-inch wheels.
- Big brake kits may need 18s or larger; check before buying.
