Tires: tires & wheels, pressure distribution, rim

Question
Can I put a 225/75R15 tire on a 15x8 rim?

Answer
Joe,

No, the range for a P225/75R15 is 6 to 7 1/2.

Please note, it is common for people to say that they can get the tire mounted and seated and therefore it works.  However, this completely discounts the fact that the footprint pressure distribution is distorted.

Hope this helps.
