Hi, I've owned my 2017 Crossroads Rezerve 28RL for almost a year now. I have a new used truck to tow the 5th wheel. Has anyone switched the stock 15 inch wheels and tires to 16 inch? My new tow vehicle is a 2016 RAM 2500 with the 6.4 Hemi which is taller than my old 2004 GMC Sierra 2500HD.

As you can see in my signature, my camper tows a little nose high. I have investigated ways of leveling mine including talking with a local man who builds flat bed and cargo trailers. His suggestion, without looking at it, was to cut off the spring mounts and weld a box frame to the I beams under the trailer, and then weld new spring mounts. However, the propane line and many other things would need to be relocated.

I had a flat tire on my return from my last outing last year. I decided I would replace all of the tires with LT tires instead of buying one ST replacement. I also decided to go with 16" wheels. I finally got around to ordering the replacements last week from Tire Rack, and they were delivered in 2 days.

I had to talk with a salesman to order the wheels, because you cannot order wheels by size on their website. The hubs on my trailer are 6 lug on 5.5" circle and the wheels had no offset. The old tires were ST225/75R15. My new tires are LT225/75R16 Michelin XPS RIB. They are made in Germany. They were balanced and delivered with 80 PSI in them.

I haven't installed them yet because I have been too busy. I am going to repack the wheel bearings as I change each one. These tires are about an inch and a half taller than the originals, so they will raise the trailer half that amount. It won't be level, but it will be closer on better tires.

Here are the tire that separated on the last trip beside one of the new ones.

Thank you for the information, I have been looking at different tire options. I have about 4 inches of clearance between the top of the tire and the belly pan on the trailer.
