Can't say 100% but I would think the larger contact on the asphalt the better.
yup.
Why not goto a 175/55 smart car tire?
ditto.
afaik, 175/55's are just a hair shorter than 135's....so you can maintain that dropped nose stance and get more rubber on the road.
allthough, i have run 135's on the front of my 64 for about 1 year (daily, all through winter) and havent had any problems (knock on wood). this is a 135 on a 4\" rim. trying to stuff that tire on a 5.5\" or 6\" rim would be too much, imho.
emilio, how wide are your empi 8 spokes?
