my snows are on taller and wider wheels. you want to think about the tires sticking out beyond the fenders. mine are just wide enough that the entire side of the van is covered from the spray whipping off the tires. if anyone reading this has pics or suggestions for fender flares (wheel well moldings) i would love to hear about it. also wondering if the factory roof rack crossbars are the best option or if there are aftermarket choices...same with tow hitch. just got rid of my truck and i need to turn the van into an suv.
