Does anyone know the biggest size tire you can put on a Dodge Durango? It's an SLT 15" rims. It's got 31x10.50's on it right now. No lift. I want to put as big a tire as I can without a lift. This is my wife's vehicle too. Any how...PM me or just reply. Thanks. 1990 GMC Jimmy 350/TH700R4/NP241/10 bolts, 4" skyjacker lift, 35x12.50R15 BFG All Terrains on 15x10 AR Baja's, Flowmasters.
