STI Tire & Wheel last week became the first aftermarket company to bolt tire and wheel products onto the new 2014 Yamaha Viking side-by-side.
At Yamaha Motor Corp., U.S.A., headquarters in Cypress, Calif., STI officials brought a set of 28-inch Roctane XD tires mounted on HD2 wheels (4/110 bolt pattern, 5+2 offset, same as the Yamaha Rhino). The lug nut studs are 12mm, so STI Lug Nut Part # LUG8, which is a 12mm x 1.25 tapered lug nut, were used.
The 28-inch Roctane tires can be used with no clearance issues, STI reports.
