The Bulldog Series wheels are the latest creation of a killer product that is here to take over and change the industry with a true big wheel wide tire. After seeing a major need for more excitement in the industry we took it upon our selves to bring something that we knew had been missing for quite some time. And that is when the 21x5.5 and 23x5.5 were born. With extensive research and development and a partnership with Vee-Rubber tires SMT had created something that they knew would not only stand out from the crowd but would also handle and ride like a dream, or like our customers say "like a Cadillac". Wrapped with a 180mm/50x21 Vee Rubber tire these over sized wide wheels remain slim and sleek with a road hugging low profile tire to show off that mean Bulldog wheel.

The 21x5.5 has been making its way up the ladder dominating the road and taking home trophies of all kinds across not only America but all around the world. With a release date soon approaching the 23x5.5 will be right behind following the tread marks of the 21x5.5. Various fitment applications ranging from custom choppers to Harley Baggers or as they say (muscle baggers) along with simple modifications like tipple trees and fender (depending on make and model) allow these wheels to dominate the motorcycle industry. The sky truly is the limit with these wheels. With imitations soon to follow be sure to contact us direct or get with one of our many dealers to purchase your original Bulldog wheel and make your dreams a reality. As they say "Ride With The Best"
