I'm wanting to upgrade to new rims for my 43" XZL tires. What is better, the steel or aluminum MRAP wheel? The steel MRAP wheel plus 395/85/R20 XZL will weigh 500+ pounds. Any issues or flaws with the aluminum wheel. Or is there better rims out there for the M35A2. Would the stock A3 rim be better than the MRAP? Will in future add waterloo's power steering kit, so an offset would be nice. It looks like the A3 rim has more of an offset than the MRAP. But I have neither to compare.
