I believe (correct me if I'm wrong) this chart goes by actual inches not just the tire size.
Example I'm running 35x12.50 but they were actually 34.25 new. Now with 20k I'm sure there closer to 34
Not a huge change in the chart but different brands have different tolerances. I sent a set of bfg's back because they were 1 3/4" smaller than advertised 34x10.50 measures out to 32.25

Yes. It's best to measure from the center of your wheel hub to the ground and then multiply by 2 to get a more accurate measurement with gearing/programmers/etc.

Chalk test work quite well also.

Lol, I think you mean chalk test for tire pressure? You run a line of chalk across the tread of your tire and drive it to see where the chalk wears. If it wears evenly, your good. If the chalk wears off in either the middle or sides, that will tell you whether you need to go up or down in tire pressure.

If it wears in the middle pressure is too high and you need to lower it, if it wears on the edges pressure is too low and you need to raise it

I've never heard of it for the diameter. How does it work?

Mark a line on the sidewall and ground level centered on the axle vertically. Drive one rotation, till the mark is centered on the axle again. Mark the ground at the mark on the sidewalk. Measure the distance between the two chalk marks on the ground. This is your actual tire size.

Totally helps.
So many things wrong with this meme! I can't tell if that's a bear, wolverine, sloth? But then again it really doesn't matter.

Someone here posted it awhile back, can't remember who, lol. But according to them, it was a grizzly bear bondage raping a dolphin. It was the absolutely most random thing someone could ever post. Lol. Glad it helped.
