The RM230 WB™ is a steer all-position, heavy-duty, wide-base tire for mixed service applications.
Tire Features
The aggressive tread pattern has biting edges to handle rock and gravel terrain and helps provide all-position traction and handling for on- and off-road applications.
The tread compound helps resist cuts and chips in mixed service applications.
Four heavy-duty steel belts promote durability in heavy-haul applications while also preserving the casing for retread.
Stone protectors in the tread grooves help protect the casing from stone penetration and help resist stone retention.
The curb bar with sidewall depth indicator helps protect the sidewall from scuffing damage and assist in indicating when a tire should be rotated to preserve the casing for retreading.
