Sakamoto Tires in Carlsbad manufactures and distributes high-performance go-kart tires from a facility on Edison Place, supplying the rubber compound that equips electric rental karts at more than 300 karting centers worldwide. The Sakamoto CCT tire's proprietary rubber formula delivers measurably faster lap times — roughly half a second per lap over competing rental brands — which is why every kart at K1 Speed Carlsbad and across K1 Speed's 100-plus global locations runs on Sakamoto rubber. Operating under the Kart1 Distribution umbrella since 2002, the company serves as the exclusive worldwide distributor of OTL electric go-karts, Protex Karting barriers, timing systems, and Sakamoto tires — a turn-key supply chain for indoor and outdoor family entertainment centers. The Carlsbad headquarters on Edison Place functions as a distribution hub that ships karts, barriers, and tire inventory to the same North County performance-gear ecosystem that includes specialists such as Running Center Carlsbad on the retail side. Sakamoto's CCT compound is engineered in multiple durometer ratings and tread patterns — including slick-surface variants for indoor polished-concrete tracks and treaded variants for outdoor asphalt circuits — across three standard karting sizes: 10x4.50-5, 11x6.00-5, and 11x7.10-5.
