i have 20' fuel hostages with toyo open countrys. purchased 5 and still have my original set of stockers. i haven't had my spare on since i upgraded the wheels. I'm going to be driving through some heavy snowfall next week. does the extra weight of having the spare help traction, i already have big honking ADD bumpers in front and rear. how many of you guys who have aftermarket wheels use the original spare in the back, or a new spare or don't carry the spare at all.. due to mother nature i expect this will be my first time in heavy snowfall in lake tahoe since i got my truck last April....
