Also talked to another owner with similar wear, he also had the recommended 50 PSI.
I put radials on, the same size and ratings and after 8000 miles the wear looks much better.

Thank you for that insight.
That is the route I will take.

[QUOTE=IMDSailor;1469177]The question I sent to Mastertow;

Hello, I’m hoping you can shed some light on to the reason for this uneven tire wear. I purchased this dolly, 80THD, last year. It had sat on the dealers lot for a number of years, I believe it’s a 08, but had never been used. I tow a 04 Chrysler Sebring with the dolly. We towed for about 3000 miles in the year. Both the left and right side are showing this wear. The picture is of the left side (While looking back) or the passenger side ( looking forward).


Mastertows response;

Oxidation, not tread wear

According to rubber industry research, trailer tires need to be replaced after 3-5 years of use, even though they usually appear to have plenty of tread left. Unlike your car’s tires, it isn’t miles of driving but oxidation of the rubber that wears out the tire. Mostly, a trailer tire sits in one spot for days or weeks at a time, and may travel only 10,000 miles (or sometimes a lot less) per year. UV radiation from sunlight and ozone from exhaust cause exterior damage to the sidewalls, and oxygen from pressurized air creates unseen damage deep inside.

In other words they skirted the problem you have completely,kind of a non-answer. I wonder what their answer would have been if you had told them the tires were only 2 years old ?

Thats kinda what I was thinking, but with other research I've done it does seem that unbalanced low quality tires will create the problem I'm facing. Along with a potential alignment problem. I've discounted the alignment because the wear is equal on both tires, if it was only one tire I would pursue much closer. Thats not to say I won't have a look at it too. Obviously I need new tires so I'll start there and see where it goes.

Thanks to everyone for the great input,
