I ordered Nitto Trail Grappler M/T 35x12.50R17E2 tires from tire direct which were delivered to the house today. They look awesome BUT a quick measurement of the tires found they are actually 34" x 11.5"... not exactly the 35"x12.5" i thought i was getting. I double checked the label on the tire itself which confirmed i did get what i paid for.

From other threads i've found that there can be a discrepancy between what is stated by the manufacturer and what is actual... i just didn't think it would be an inch less in both directions!! If i had wanted a 34" tire i would have ordered a 34" tire (if there is such a thing).

Does a tires dimensions change at all when actually installed onto a rim and are inflated?

Thanks for listening...

They do change some when they are mounted on the jeep!

 

Once installed and inflated they might measure 34.5"...being rounded to 35" If you look at a tire on Quadratec it list the publish size and the actual size.

 

Shouldn't be a surprise since it's been mentioned a million times in a million threads. Tire companies use fisherman rulers not standard rulers.
