If you require special size tires, or run a different compound than usual (Blue and Green are most popular), please make sure to PM us through here or email: tires@bostonmoto.com with any requests!!! As you can imagine we order tires in quantity, and are coming up to speed with what racers' preferences are, so to ensure your tire is on hand and in stock, shoot us a note and we'll have them ready and waiting for you at the track.
