you realize that if you're purchasing them soley for a winter setup going bigger is detrimental towards your cause right? The smaller width wheel/tire setup you can run the better in the snow. But yes, you should be able to run 37's if your backspacing/offset's agree with you (that is crucial) and you're willing to do a decent amount of trimming of your front bumper.
yah i need new tires regardless and just dont feel like buying a set of winters and then come spring time buying another set. but i think im just gunna get a set of 35's and then come spring time just do a leveling kit in the front so i wont have to trim as much of the bumper
