I can’t say 100 percent, but I am pretty sure 37’s will rub no matter what offset you run without collars or springs. At the very least you will rub with any compression while off reading. The plus 12 offset will help but the 37’s will likely still rub. You have a better chance if you run BFG’s since they are not true 37’s, if you run Nittos they are even taller and will rub for sure. I think you will need springs or collars.
