Selecting the right FJ Cruiser tire size can dramatically enhance both the performance and aesthetics of your vehicle. The Toyota FJ Cruiser is celebrated for its robust off-road capabilities, retro-inspired design, and overall reliability. Whether you’re gearing up for a rugged off-road expedition or seeking a daily driver setup with a comfortable ride, understanding tire dimensions and specifications is vital.
What Is the OEM Tire Size for the FJ Cruiser?
The original equipment manufacturer (OEM) tire size for most Toyota FJ Cruisers is 265/70R17. This size:
- Offers a balance between on-road comfort and off-road capability
- Provides a good profile for tackling mild off-road terrains
- Ensures reliable handling in various weather conditions

Factors to Consider When Choosing an FJ Cruiser Tire Size
- Suspension and Lift Kits
Larger tires often need additional clearance. A lift kit not only allows for bigger tires but also improves articulation on uneven terrains. - Gear Ratio Adjustments
Going for a larger tire size can impact your gear ratios. Re-gearing can help maintain optimal performance and fuel efficiency. - Tire Type (All-Terrain vs. Mud-Terrain)
- All-Terrain (A/T): Balanced for on-road comfort and moderate off-road use.
- Mud-Terrain (M/T): Aggressive tread pattern built for extreme off-road environments but can be noisier on highways.
- Fuel Economy Impact
As tire size increases, rolling resistance and vehicle weight may also rise, which can reduce fuel efficiency. - Rubbing Issues
Larger tires can rub against the fender or suspension components. Proper backspacing, wheel offset, and minor body modifications help prevent clearance problems.
Maintenance and Safety Tips
- Regular Rotation: Rotate your tires every 5,000 to 6,000 miles to ensure even tread wear.
- Correct Air Pressure: Maintaining the recommended tire pressure extends tire life and improves handling.
- Alignment Checks: After installing new tires or modifying suspension, get a professional alignment to prevent uneven wear.
5 Frequently Asked Questions (FAQs)
- Q: What is the most common OEM tire size for the FJ Cruiser?
A: Most FJ Cruisers come equipped with 265/70R17 tires, which strike a good balance for everyday use and light off-roading. - Q: Can I fit 33-inch tires (e.g., 285/70R17) without a lift?
A: In many cases, 33-inch tires can fit with minimal trimming or a leveling kit. However, some rubbing might occur during full articulation or tight turns if no lift is installed. - Q: Do bigger tires affect gas mileage significantly?
A: Yes, larger and heavier tires can reduce fuel efficiency by increasing rolling resistance. Proper maintenance, tire pressure, and gearing adjustments can help mitigate these effects. - Q: Are mud-terrain tires louder than all-terrain options?
A: Mud-terrain tires generally have an aggressive tread pattern, which can produce more road noise. If you mostly drive on highways or city streets, all-terrain tires might be more comfortable. - Q: Should I re-gear my FJ Cruiser if I upgrade to larger tires?
A: Re-gearing is recommended when moving to significantly larger tires to maintain optimal performance, proper speedometer readings, and better fuel economy.
