I have an 86 4Runner which is equipped with tires that are 31x10.50x15. I've noticed the book says the tires should be p235x75x15. What is the difference between these 2 tires??

I have an 86 Toyota 4Runner which is equipped with tires that are
31x10.50x15. I've noticed the book calls for tires that are P235x75x15. What is the difference in these 2 tires??Joe
31x10.50-15
That's a 31" diameter tire which is 10.5" wide and it fits a 15" rim To convert to metric:
31" tire - 15" rim =16" total sidewall.16" total sidewall = 406mm
406mm/2 = 203mm sidewall10.5" width = 267mm ~ 265mm
Take 267/203 = 76% ~ 75%
approximately you got a 265/75 R15 tire (it's not exact due to rounding)
Go here:
Go here:
Your tires are 2" taller than stock size, which should translate to about a
9% reduction in your final drive ratio, and 9% error on your speedometer.
"the book"? The owners manual calls for 225/75x15 but they are not a popular size so tire dealers substitute the 235.
Thank you all! I didn't expect an answer so fast and then so many. My next question would be why would you put tires that are 31x10.50x15 on a truck when I would think the P235x75x15 would be easier to find?

Extra tire height, greater ground clearance under the truck for off-road use. Many of the light truck tires only come in the inch sizes, 31x10.50 is a very common size and some Toyota 4x4s came with that size from the factory.

The 31's are a very popular tire size for mini trucks and suvs. They give you a slightly higher and wider stance. Any tire store worth a damn should offer a good selection in that size.
Thanks! good utility!
