I know that this reply may be reaching you late, I need to read the forums a little more often. On my contour I put 195/70/14 on with no problems. I just liked the little more peace of mind I got from having just a little more meat of the tire on the road. From there I went up to 205/65/14 the next time I changed tires. Now I've got new rims and have 215/40/17 on the car. Whatever you do, make sure you get them aligned with whatever size you decide to go with so you don't eat up you new tires. Good luck, MIKE.
