I have 235/70/R15's on my truck. Which number is for the height of the tire? That is the one I am looking for. I guess it's probly the middle number. Or is it? The only one I am sure of, is the R15, I know that means it's a 15 inch rim. So er, anyone have any pics of some tires on your truck that are taller than that? Not those giant mudding tires of course. Just some tires that look like they could have come on the truck. I am asking cause the local tire shop accidentally put on 1 tire that is taller than the size I listed above, and it looks a lot better to me. This was after the tread separated on the old tire.

the tires you have now are 28" tall, this might help

heres then formula for metric to english
235(width)* .7(side wall ratio/aspect ratio) *2 | 25.4(mm to in) + 15" (rim dia)= 27.9"
this works for all metric tires
