The widest tire for a 9-inch rim is a 265 mm tire. This will provide you with enough contact patches with the road without bulging the tire outwards. Also, a 265 mm tire won’t be rubbed against the suspension and a 9-inch rim will be enough to support this wide properly. Don’t put tires wider than that if you want to avoid poor handling.
This article will explain with additional details what is the widest tire on 9 inch rim you can use.
What is the Widest Tire on 9 Inch Rim?
To determine the widest tire on a 9” rim, you have to add 1.5 inches to the rim size. In this case, the widest tire for this size rim would be 9+1.5 = 10.5 inches or 266.7 mm. So, the widest tire you can go for with a 9-inch rim is 265 mm.
However, this is not the standard size. It is recommended to use a tire 0.75 inches to 1.15 inches wider than the rim size. Look at the following chart to get the maximum, minimum, and standard tire sizes for a 9-inch rim.
| Rim Size | Minimum tire width | Standard tire width | Maximum tire width |
| 9 Inches | 235 mm | 245 or 255 mm | 265 mm |
For choosing the widest tire for an 8.5 rim or other sizes rims, you have to take a similar approach. It is best to use the largest rim that fits the tire properly for the best performance. In addition to adding weight, going bigger will distort the shape of the tire.
Can I Put 275 Tires On a 9-inch Rim?
On 9-inch rims, you can use tires up to 275/40. Depending on the tire, some say 275 is the widest you should go but you might experience cupping. According to others, anything over 255 would be too much.
So, you can not put 275 tires on a 9-inch rim. Although many car owners use 275 tires on 9-inch rims, you should not. 275 mm is too wide to fit in a 9-inch rim. It will cause some problems.
- The 9-inch rim will not support the tire properly. It will cause reduced handling performance, uneven wear, and potential damage to the tire or rim.
- As the rim is narrower, the tire’s sidewall will get curved outwards. You will not get adequate contact area with the road. It will affect the tire’s overall shape and performance.
- The tire will get too close to the suspension and while driving, the tire will keep brushing the suspension. As a result, the suspension will wear out too early.
With a 265 mm tire on a 9-inch wheel, you won’t face these problems. So, 265 mm is the widest tire on a 20×9 inch rim.
