Few months ago, I picked up a 2001 swift(50k), with a minor dent and a missing mirror, for $2500. mostly for my girlfriend to have a car to drive.... The wheels on it, looks like stock, steel, maybe 13 inch? 14? small, very small and very thin. and the tires are what I call donuts on any other normal car. I plan to ride out these tires till winter season comes again... The wheels have some little dings in them, I want to replace em with some alloys anyhow. I was thinking 15 inch alloys. so far, even with the very thin tires on this thing, the handling really isn't all that bad. And the braking power more than satified my girl friend when she came from 35mph to a dead stop without any problems, to avoid a collision... with this in mind- would a wider tread pattern tire hender or help the overall handling of this car? I hate the way it looks with donuts all the way around... but it is a very small light weight car that could probably use a bycicle tire as a spare in a pinch, (hehe)... I was thinking, a wider tread tire would reduce the wear rate a little. and improve cornering. But- what about hydroplaning? seems on a light car, a wider tire would provide more "lift" when going through water. what about snow/ice? seems like a wider tire would have less weight per sq inch and not "grab" a slick surface as well. any thoughts? sugestions?
