Whos running 15x3.5s on the street?
I don't street drive my car anymore, but have run them (Centerline 15x3 1/2" with 600x15's) for many thousands of miles in the past. No problems at all as long as you watch out for potholes. As far as handling goes they work fine as long as you obey the speed limit. One look at the car with them on should tell you it will not corner as well. Meant nothing to me as I always babied the car and drove 5mph under the limit anyway to save it for the strip. (The only good street machine is a bus!) Always got a lot of looks and comments (positive) on them when I ran them on the street. To me a car just does not look right without skinny front tires.
