Wheel seems ok. I have checked into LT tires but I dont really want to buy new 16" rims, and Im not sure that I have much more room between the top of the tire and wheel well. I did look at the date on the tires and all four were made in April of 2011. We bought it brand new and this is our second season with it. I was always skeptical of all the talk about chinese made tires but obviously there is something to it. I check my tire pressure religiously. I am OCD about appearance and up keep of the trailer so everything was well cared for. Its even stored inside so the only time the tires are exposed to the elements are when we are camping. Totally ruined my Thursday night, but at least the rest of the weekend was good.
