I don't like using pipe wrenches to tighten axle nuts because of the gouges they leave in the surface.
So, I went to Harbor Freight today and picked up a very large crescent wrench. It's on sale right now for $29.99 and if you take a 20% off coupon, its only $24.00. Good news is that it will work on aftermarket and stockers.
Actual size shown below and yes my tool IS REALLY THAT BIG - 24" TO BE EXACT. Now go get you one and quit tearing up axle nuts.
