I upgraded to the HWT Hi- Spec wheel also and am pretty pleased with them. It's been about three years and I've noticed the protective clear cost is showing signs of cracking. I'll see how it goes. One point, after getting the best online price I went to my local tire dealer who matched the price. I figured I would let him handle the order and deal with any problems.
I just bought new rims for my 5th wheel. While researching whether to buy Alloy or Steel rims and in talking with a Goodyear salesman I was told that he suggests steel rims for trailers because of the extreem pressure put on them in tight turns, his reasoning is that steel rims will bend and alloy rims will not and he has seen them crack due to the pressure. Those facts and the cost lead me to steel rims. Yes they had both alloy and steel rims.
If you've ever watched your rims backing into a tight spot, you know what he's talking about.
