Let's talk about trucks

You gonna start rd x ing me again?

What's your beef?

You gonna argue that a "235" tire is not 235 mm wide?
No, that just because the thing is stamped "235" don't mean that it is . . I've had vehicle pull problems after a set of 4 tires were put on, and yes they were the same brand and type. We found out the pull was because one of them, even though marked the same, was 3/8" shorter overall than the other 3...
Another instance
When my son started driving we went into wal mart and just looked at tires. We didn't buy there, but they have an "open warehouse" stocking system where the customer can walk the aisles of tire stock and see what all they have as opposed to having them stocked somewhere in the back where customers can't access them. I pulled 3 "all terrain" tires of the same size, but different brands/and put them next to one another on the ground. No 2 of the 3, were the same height. There was well over an inch of difference between tallest and shortest of them, all marked the "same" size.
