I went from 15" ST LRD tires to 16" LT LRE tires. Everything looked OK when I put them but I wound up having clearance issues. You need a minimum of 2.5" above the tire as clearance for suspension movement. I thought I was OK until I took the first trip and saw the black rubber dust up under the wheel wells...I only had about an inch of clearance and while it looked OK while parked, every time I hit a bump the tire rubbed.
I wound up installing the Correct Track II alignment kit which also adds 2" of height to the trailer. That fixed the clearance issue.
Of course the factory ran the 1/2" black pipe for the propane tight to the inside of the frame, so installing the kit meant relocating about 20' of pipe (all the gas appliances are ib the rear of the TT so it's a loooong run from the tanks up front).
Then I needed to re-adjust the hitch again so the TT would tow level, which meant ordering a new stinger bar from Hensley.\
All in all, very happy with the upgrade and no more blowouts. Point here is that if you go this route, be prepared for additional work and expense you may not have planned on.
