Hi ScottM,
If your rig is 29 feet or longer with one or more slide outs, you might want to consider those extra-capacity E-rated tires. It's like 500 pounds more per tire which means 2000 more pounds for the rear axle and 1000 more pounds on the front. But there is such a thing as "too much". A shorter lighter rig with over-rated tires translates to a more harsh ride. Just about everyone would agree that the continuous earth-quaking when being driven is undesirable. You don't want to make it unnecessarily worse.
For our 24 foot (2007 E350-DRW chassis) rig with no slide out, I am buying new tires in the next few weeks. I decided on Michelin Agilis CrossClimate 115/112R. Discount tire gave me a price on 6 for $1316 out the door. Our rig is 14 years old with 38,000 miles and still has the original tires in-part because we garage our rig. I had such a good experience with the original Michelin LTX tires that made no sense to try a different brand. I also like that they are "Made In USA".
Ron ... I'm curious.
Why are you going to have 115 tires put on you motorhome? Didn't it come stock with 225 tires on it like mine did ... along with so many other E350/E450 based motorhomes?
(I retrofitted our Class C with 115 tires in order to provide slightly more ground clearance.)
