Biggest tire under a stock suspension dart????

Any tire shop worth their salt will be happy to work with you, on the rack, to figure out which tire will work best for you. Show up with your car and your rims and they will mount tires till your happy. They have a product that they want to sell. Even better, if you can find a time of day/week when they are a bit slow. This will take all the guess work out of it. Good Luck and remember to report back on your experience.
