So they measured the tires. One pair of tires is actually larger then the other pair of tires. The two tires where the X-chock will not fit add about ½". I never rotated the tires and those are the two that take the most abuse in most turns. The two turns in the driveway are left turns, and I try to avoid blind turns (right turns) when backing up, so the majority of turns backing are to the left.

Maybe not, especially if we are in the early stages of belt separation.

Could very well be belt separation. I had that happen on some ST tires a few yrs ago but I too did not recognize the problem right away. Fortunately, one tire started loosing air pressure and the TPMS when off.

Stopped w/o damage to the tire, I even thought the tire could be patched and took it to a tire shop. Leak check discovered multiple leaks at the bottom of the tread grooves at the edges where the tread wrapped onto the sidewall.

I debated replacing all four tires, made the decision to do it but had to drive 40 miles to the nearest Discount Tire. While driving, several of the tires were rubbing against the fender skirt and inspection at the tire shop also showed they were rubbing against the underside of the trailer floor. Even then, my initial thought was a suspension failure. But, while the other 3 tires did not have air leaks, all showed the same tread failure, at the bottom of the grooves you could actually see the tread cord showing and this was over 1/3 of the tire circumference. My tires had grown in size more than what you are seeing, but 3 never leaked.

With the sharp turns you have to do, tread separation is very likely and you should probably replace all 4 tires. BTW, if the tires are original ST tires they are due to be replaced anyway, 3-5 yrs is the recommended maximum life for ST tires from several brands.
