Trailer tires are just not built to the same quality of tread-adhesion, I've had several that were not old enough to be too old, peel the tread right off without warning. Nice big stripe all the way around, shoulder to shoulder.
I'm sure this will also garner a response from the Failurestone Tire crowd, but I also don't automatically put everything rubber at 35psi like it seems tire shops always do. Doesn't matter what vehicle I've had done, they *always* set them at 35psi, even with tires that are 50psi max, which means that the tire has now been set 40% lower than the rating. From the Ford Explorer lawsuit years ago, tire manufacturers stated that they were increasing the potential for heat failure (due to increased flex) with tires lower than 10% below the max and that the car manufacturers were not specifying correct pressure numbers.
I run my tires pretty much all at the sidewall max, and before anyone has the chance to scream that this must be happening - No they aren't wearing out in the middle first, they are wearing square across the tread. Also not every car has as much adjustment as they used to. My VW Jetta has basically no adjustment for the camber, so said an alignment shop. Only the toe can be adjusted. So if those tires want to wear strangely... Rotation is the only "cure" and it isn't a cure, it just moves the wear around. Last set of tires I put on that car had run for longer than their mileage warranty (75k miles) so I think I'm doing pretty good.
You really don't have a clue on how load ratings work and air pressure do you?
"Just set at max psi" and your good is not a good idea,even for trailer tires that often never see anywhere close to max load.
Oh and by the way your VW does have both camber and caster adjustments,granted you can't set individual camber/caster but you can adjust to even camber/caster between the left and right sides.
