How is this jk technical related?

Km2s have a softer sidewall, and are very compliant when aired down. At lower pressures, with weight on the tires, the sidewalls are softer and the overall measured height is smaller. And yes this is pretty common knowledge that km2s measure smaller when mounted. My km2s are more compliant at 15psi than a toyo mt at much lower pressures. So I don't have to be as concerned about losing a bead.

You could go with a much stiffer tire that is significantly heavier if the extra 1/2" of clearance makes all the difference in the world. You'll lose more mpg, and decrease acceleration and braking performance. Every tire has its weak and strong points.

Technically it is technical related. Especially when we get talking about sidewalls and tire flexibility when aired down. Plus the fact that the OP put them on a JK.

Speaking of air-down compliant, I suppose it has to do with the load-rating of the tires. Toyos are pretty-heavy duty, and they're also one of the heaviest tires on the market. I presume the load-rating is way up there, too.

It's a guy thing. We always claim that things are bigger than they really are.

What? You guys don't do that?

"Overstating" or measuring smaller than others... either way you end up with a short tire.

I think the measurement should be in MMs--

Then it would always sound BIG !

The 35" r15 MTRK's were almost 34 right on the money brand new no weight on the tire. There is just variation in the tire making process it seems.

How much does wheel width affect the tire height? Say like a 35X12.50X17 on a 8" vs. 10" wide wheel. Probably minimal I'm guessing.
