How to understand metric tire sizes

I just barely put those size on with 0 offset rims and a TSB Leaf in the back, stock lift in the front. Rubbed on the front mudflaps only when turning. Took them off, no problems with rubbing

 

265/75/16 should not rub the fender or flaps with stock wheels

 

Would the 0mm offset be the reason it rubbed on the front mudflaps?

 

great thread man thx

I've always just used a tire calculator. There's another one that'll show you comparatively the difference in tire size.

 

The thread is meant for people to be able to understand what the numbers mean more so than just derive what size a particular tire is

 

Thank you for sharing. I always forget this stuff

 

I found this calculator on a vw parts site, I thought it was particularly handy for tire calculations and gear ratios

you just have to scroll down to see the calculator

 

Sweet now I know. I still think I am going to leave it to the local tire and suspension experts to do what they do best lol. Still awesome detailed information, pretty easy to understand, thanks for the write up.

 

I just tried the calculator and it wont let me use 31 x 10.5 x 15 as my current size.

 

It's a metric tire size calculator

 

Ok so what is the metric equivalent of 31 x 10.5 x 15 ?

31" is the outer diameter of the tire?

10.5" is the width of the tire?

Looks like 265/75/15

 

Got it! Thanks.

 

This is great info but complicated. if you go to the Cooper web site, they have a table that shows i.e. 265/65R17 equivelent in inches much easier than doing the math. I put 245/70R17 on for snow tires. Wanted to make sure the diameter was equivalent. checked the Cooper table and it told me that the '245' is 1/10th smaller and 1" narrower than the '265'.

 

Tacomaworld ROCKS!

 

Where do I find rim information? Is this embedded on the rim itself? For example, I want to know what my rims are made out of, and the name of the rim. Thanks for helping.

 

Call a toyota dealer and give them your vin.

 

Is that the only way to figure this out?
