bought a set of $800 tires and les schwab insisted siping would prolong, as well as enhance performance of the tires, so i had it done. its been about 6 months now and the tires are coming apart in chunks.
i have been to two stores, including the one i purchased the tires at. neither store thinks anything is wrong, its just cosmetic. i personal have junked the tires, voiced my opinion, and will never by from les schawb again.
im just stunned that a company so big won't back their product and rplace a couple tires...
oh, and i told the rest of the united states army to do the same. later les!!!
