I am having my XD spy wheels installed today and I was asking the guy at Discount Tire what the biggest tires I can install would be when my current stock tires wear out. He said I could jump from the 265 70 17s to the 285 70 17s with no modifications. He said these would be about 2 inches taller at 32.7 inches. Does anybody happen to have a picture with that size tire on their truck. Just wondering if that would fill out the wheel well better or if I should do a leveling kit.

 

i'm hoping someone comes forward with a picture too... been looking on youtube and other forums but with no luck.

 

Actually, the size varies by manufacturer but in pure size comparison, the tires will be only 1.1" taller and about .8" wider.

This is the way to figure out the tire size
265 = metric width (25.4 mm in one inch)
70 = sidewall % ratio to tire width
17 = rim size

265 converted to inches is 10.43 " wide
285 converted to inches is 11.22 " wide

70% of 10.43" = 7.30" sidewall
70% of 11.22" = 7.84" sidewall

Double the sidewall (top and bottom) plus the rim = tire height

265 70 17 = 31.6" tall
285 70 17 = 32.7" tall

 

Great post Pedro, thanks! Doing that math a 295 tire would come out to 33.26. Is this what people mean when they say they have 33s on their truck? Seems like these 285 would be about a 1/2 inch smaller but may still look good. Hopefully somebody will be able to produce a picture.

 

Look what I found when I used the search function.
