It seems odd to complain when someone sells you what they say they are, but.
The last few sets of JK tires I bought were almost exactly the size they were labeled to be. So what is to complain about?
For years, I bought .820" rears and .750" fronts and they measured something like .840" and .775" or something like that. JK lists rear tires at .840 but only on .600" rims. and no oversized fronts at all. These all work but I like to start off with a bit more rubber on new tires so I can adjust and/or practice.
What size tires do you want coming out of the tube new? As stated or something over?
I tried to email JK but my email got bounced back undeliverable.
