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? Because your vehicle’s weight will all be on the center of the tread. Also, none of the weight will be on the sidewall of the tire, and that’s wrong.

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.
Will A 9 Inch Wide Tire Fit On A 8 Inch Wide Rim?
Yes, a 9-inch wide tire will fit perfectly on an 8-inch wide rim. It will leave enough room for the tire to move freely. Also, your vehicle will also look good.
Can You Put A 10 Inch Wide Tire On An 8 Inch Rim?
Yes, you can. If you make your conversions correctly, a 10-inch tire, when converted to millimeters, is 254 mm (which is basically 255 mm). Here, the answer is clear, as we have established above that a 255 tire will fit on an 8-inch wide rim. Just keep in mind that this installation does cause some aforementioned problems.
Can You Mount A 12.5 Wide Tire On An 8 Inch Rim?
Yes, you can install a 12.5 wide tire on an 8-inch rim. However, this tire size will also greatly affect the shape of the tread and sidewall of the tire.
What Is The Widest Tire On 8.5 Inch Rim?
The widest tire that is best recommended for an 8.5-inch rim is the 255 tire. This recommendation comes from various tire makers.

FAQs About 8.5 Inch Rim
Can You Fit 285 On An 8.5 Inch Rim?
No, you cannot fit a 285 tire on an 8.5-inch rim. If you must fit a 285 tire on your vehicle, you need a minimum rim size of 9.5 inches. Because the 285 tire is too wide for an 8.5-inch rim, it will put you in great danger.
Will 235 Tires Fit 8.5 Rim?
Yes, it will. The 235 tires will fit an 8.5-inch rim perfectly without any form of rubbing. They look great, feel great, and have adequate clearance. There are simply no drawbacks to fitting a 235 tire on an 8.5-inch rim.
Will A 245 Tire Fit An 8.5 Rim?
Yes, a 245 tire will fit an 8.5-inch rim. The recommended rim width for the 245 tires is 8 inches to 9.5 inches. This implies that a 245 tire would fit an 8.5-inch rim and would move without any form of rubbing.
Can 265 Tires Fit 8.5 Rims?
Yes, but with a little problem. A 265 tire may fit on an 8.5-inch rim. However, as we said earlier, the widest tire you can fit on an 8.5-inch rim based on tire manufacturers is the 255 tire. These manufacturers recommend that you use a minimum of a 9-inch rim to fit a 265 tire. If you were to fit a 265 tire on an 8.5-inch wheel, it would most probably rub on the suspension.
