I'd like to, but that will require swapping the axle to account for the bolt pattern, tire/rim width and offset, and probably getting custom fenders for coverage. AEV makes some large center bore wheels that would match, but with a bolt pattern that matches the trailer, but it's not worth it if I can't share the spare. I'd also have to reconfigure the lunette since I'd have to go spring-over if I were to matching 35's, and that didn't work with my current hitch height and interfered with my spare. So maybe some day, but between work around the house and the trailer build, the coffers are dry at the moment!
