What Is The Widest Tire On 8 Inch Rim?

The widest tire you can fit perfectly on an 8-inch rim while remaining safe is the 245 tire. Any tire size wider than this will make the tread of the tire curve. Why?

FAQs About 8 Inch Rim

Will A 255 Tire Fit An 8 Inch Rim?

Yes, it will. Although the 8.5-10 inch rim is the recommended rim size for the 255 tires, a 255 tire will fit on an 8-inch and will provide enough clearance. 

However, there are some issues that you should notice. When you mount 255 tires on an 8 inch rim, the sidewalls will angle outward. This will affect their performance as a suspension component. Furthermore, the tread can be bowed, decreasing the contact patch. So, we highly recommend you should choose a 245 tire instead of 255 for better performance if you need the widest tire for your vehicle.
