STI introduced the Roctane XR with a 35-in. trail-eater tire made for 18-in. wheels. With its 9.5-in. wide sizing and new 8-ply rated carcass, the Roctane XR delivers lightweight, all-terrain performance at a great price. Starting with the original Roctane XD, STI re-imagined a lighter, all-terrain, trail-oriented tire to make the new Roctane XR. By adding dimples and grooves to the familiar tread pattern, STI increased the biting edges available through the XR’s main contact surface. With its superior traction and precise handling, the Roctane XR sets a higher standard for all-terrain performance in the 35-in. tire game. The Roctane XR 35-in. retails for $239.
The Baja-tough STI HD9 Beadlock wheel line grows again, with the new 18-in. application. Designed to serve the market for increasing tire sizes (like the Roctane XR 35-in.), this new HD9 Beadlock is made for performance and durability. The HD9 Beadlock uses a 10mm thick beadlock ring secured by 5/16-in. grade-8 hardware for extra strength. Plus, the wheels include a bolt-on center cap and pre-installed valve stem with black sleeve and matching cap. The new 18-in. HD9 Beadlock comes in two finish options, Matte Black and Matte Black / Machined. The STI HD9 18-inch wheels retail for $235.
