..........and still be able to drive with the stock wheels and tires in the snow? I plan to eventually buy an aftermarket set of wheels and tires after I lower my 2002 Supercrew. However once the snow starts to fly up here in Canada I will need to put the stock ones back on. What is the most popular lowering configuration for this situation?

Also, does lowering the truck void the warrenty?

Thanks for your input.
