unless your gonna take it to a wash regularly. i use my stock wheels w/ snow tires for winter and 17s w/ summer tires for nonwinter use.
when driving in snow dont go thru the gears too much. try to keep it in the lower gears (the big benefit of mtx). i've gone around a corner at maybe 25-30 w/ allseasons on the 95gl and was in 3rd and spun the car 180degrees. luckily there was no traffic in opposing lane. i was in 3rd and should've stayed in 2nd while slowing holding the brake. it was a slight turn slightly downhill. u get the urge to go to 3rd and 4th.
i usually keep it in 4th on the hwy and i generally dont break 45mph (when it snows obviously). i may be the slow loser in the right lane but i'm getting home in one piece. the gl has snows on the front tires only (some will argue this but its got allseasons in the back). the svt obviously had to get 4 snow tires (dont run summer tires in the winter).
also u want a thinner taller tire to cut thru the snow. wider isnt always better.
