HELP!!!!!! 96tt. can't find matching set in 16" anymore. looking to go to 17". Tire Rack gives me mixed suggestions. I can go with 235/45/17 all around with a 17x7.5, one guy said use 17x8 all around. or 235/45 fr and 245/45 rear with a 17x7.5 if I want wider in the rear. someone else said I can use 255/40 17x8.5 in the rear with the 235/45 17x7.5 front. simple ordinary mixed street and highway driving.
