hey whats up guy, well i work for discount tire and i would not do the ride match simply cause it is really for people who have vibration problems.it does not increase tread life, it is just like the other guy said it measures the heavey spots in the tire and matches the tire and wheel perfect...as far as the tire replacment or certs as we call them, i would get those casue regaurdless of whether you autox or not what will you do if you get a nail in the sidewall?we wont be able to fix cause of safty issues so we would replace it for free cause yo have the certs, and when you order the tires ask the guy if it comes with a milage warrenty, cause if it does and you drive 20,000 miles on the tires and the milage warrenty says that it will go up to 30,000 miles and they are worn evenly at 20,000 then we will do a milage adjustment cause it did not reacht eh 30,000, so check it out and let me know.
thanks, justin
