STI says bigger is better with Xtreme duty tires
STI has released a new 34-inch version of its 8-ply radial Roctane XD tire, which is now the tallest tire of its kind in the class and features the deepest tread.
“Built to confidently handle today’s ‘bigger is better’ UTVs, the new 34 / 10R-15 Roctane XD joins 11 other sizes to create a family of ‘Xtreme Duty’ tires like no other, STI says in a release.
According to STI, Roctane XD tires use a heavier denier nylon cord to maximize tire toughness while retaining flexibility for a comfortable ride. The Roctane’s unique, non-directional tread design and wide profile footprint deliver smooth, quiet operation and precise control.
“STI’s exclusive RocWall sidewall construction features reinforced lower sidewalls and extra-wide tread belts for added shoulder protection and stability,” says STI. “Add in super-deep RocGuard rim guards to protect even the thickest wheel lips from trail damage, and the result is the most reliable tire on the market. The Roctane XD’s specially formulated tread compound extends its life even further, yet it still grips the slickest rocks like a dedicated wall-crawler.”
The new 34 / 10R-15 Roctane XD is available now for a suggested retail price of $293.52, through authorized STI retailers.
