[Carl n Susan]

I happily towed a 2005 2955RL over 50,000 miles. The D52-8 means the axle is rated at 5,280 Lbs. A "good" LT tire is rated at ~3120 Lbs. Two of them gives you almost a 1,000Lbs. of extra capacity over the axle's rating. There is no need for 110 PSI tires and rims. That year 2955 was originally delivered with Larado LT E rated tires and I just replaced them with Toyo's from Les Schwab when it was time.

I was concerned that others were bending the D52-8 axles so I upgraded them to the 7K ones. I also installed wet bolts with the axle change. Those are the two things I would recommend over 110 PSI tires and rims (and cheaper too).
