Not really the primary, as I saidI think traction is the primary concern. Handling and traction in the snow are greatly increased with the 15" wheel over the 16" or the 17". For example... this is the tread pattern of the tire on my car with the 17's http://www.tirerack.com/tires/BigPi...F1GSD3XL&vehicleSearch=false&fromCompare1=yesFocusedat50 said:I forgot to mention, the past few years we only got snow 2-4 times a year so salt would be minimal. ( ok, now that I've said that I just know it's going to snow like hell this year, crap.[ohcrap] ) Is salt the primary concern for custom wheels? I can have my car washed for free everyday at the dealership, it's part of the deal when you buy a car from them.
