I have a rough country 5" suspension lift, im running 20x9 wheels with 4.5 back spacing and -13 offset wanted to know if i could clear 37x13.5r20 tires. Thanks. Truck is a 2008 ram 3500 srw

 

You can clear 35" tires with a level on all the generations with the right width and offset. When I say clear I don't mean flexing. Anyways my 96 is leveled with a little inner fender trimming and I'm runnin 38x15.5r20 . Rubs at full lock and it can rub when I'm flexing it. I used to have 37x12.5 though and they didn't rub at all on the street. I'm sure you can fit those 37 with the lift. Keep in mind 5" of lift is only 2" over a level in the front. Might rub a bit with turn or flex but I'd run it and figure it out. Sure you'll be able to fit those maybee with a few tweaks
