:DI am running 36x12.50x15 swamper sx's on 15x8 10 hole aluminum rims. Best tire I have found to date. I have a Spring Over with wrangler springs fr and rr, 1" body lift, missing link (home made) fr and rr, Toy axles and lots of fender "massaging" with a 10 lb sledge. I finally put bump stops in and it make a world of difference. It's on a 1988.5 tin top Sami. This size allows me to wheel almost everywhere. I started in stock (!) form and have run the 31's, 33's, etc. All good sizes with the proper driveline upgrades. Good luck!
