Can you use the same rims for 31x10 50r15 with p235 75r15?

No, you cannot use the same rims for 31x10.50R15 and P235/75R15 tires. The 31x10.50R15 tire has a wider width and a different overall diameter compared to the P235/75R15 tire, which may lead to improper fitment and safety issues. It's essential to use rims that are compatible with both the width and diameter specifications of the tire being mounted. Always consult your vehicle's specifications or a tire professional for the best fit.
