I was told a few minutes ago that you can't rotate the tires from front to rear on a Dodge Ram 3500 because the load rating is different on the front than the rear, is there any truth to this. I have a 2014 Ram
If you have a 2014 RAM 3500 as I do with the Alcoa aluminum wheel package that is pretty standard on the "well dressed" models, the rotation pattern is: Front and rear outers can be rotated front-to-rear, same side (no need to cross). The Alcoa wheels are reversible (you just flip them over), the tires do not need dismounting. The inner rear wheels are steel, and those get rotated side to side only.
Anything more than that requires tire dismounting and is probably a waste of money. I've owned RAM 1-ton dually trucks since 1994, and this is the pattern always used unless you have all six steel wheels. By the time you chew up the outer 4 tires with outer edge wear that is inherently caused from towing very heavy trailers, I usually find the inner rears are half-worn any way and might as well replace the entire set. I average about 50-60k out of a set of tires, or usually hit the 5 year mark to replace them due to age before they are truly worn out.
If you do the math, tire mount-dismount and rebalance (plus TPMS care) will cost $25-50 per wheel. Lifetime tire rotation and rebalance plans normally do not cover this extra labor. If you rotate your tires every 10k, and do that over 60K, you've spent maybe $600 on the low side if you are swapping 4 of the 6 tires between the steel and aluminum wheels to enable their front-rear movement. You just bought yourself another 4 tires (avg cost $150/ea) or so in mount-dismount and rebalance costs over the life of the tires. You hit a point of diminishing returns in my opinion. Having been in that industry for many years, I recommend saving that money for new tires.
