actual true tire size 315 or 35s... (1 Viewer)

[GW Nugget]

Hello Gary here...
Im on the market for some new rubber & I need your help. I live in a rural area 100 miles from any decent tire shop & even then they don't have 315s of 35s in stock.

Manufacturer specs vs true tire size & even revs per mile are all messed up. Some list a taller tire with more revs vs a smaller tire with more revs. Example: a tire reads 34.8" & 598 revs & another list as 34.3 & 577 revs per mile. That's a contradiction.

Will someone give a true horizontal reading of your 315 or 35 inch tires and tire pressure.
Please state tire type, size, pressure & horizontal dimension.
I'm looking for a short 35 or a tall 33, really looking for a 34, but a skinny pizza cutter.
Thank you for your time & consideration.

Duratracs are not true to size. My 315/75/16's measured just under 34" mounted on the truck @ 42 psi.

Remember though it is not always the caliper that you have to be worried about. Once the tire is mounted take a look at the TREs as well. While the caliper may fit the TREs may hit the tire at 3/4 turn or full lock.
