I used 245/60/15 Cooper Cobras on my Mustang through the last 3 winters, without any problems. Well....there was the one time when the city plowed me in, but I was parked in the street. Anyways, my mods were everything in the sig, except the heads & cam. The only weight I added to the trunk was my battery, but that's for racing purposes

. The important thing to remember is to take your time. Fortunately, I've been able to retire my car from daily driving status.
