SP 181™ Line-Haul Trailer Tire
Features
- 12/32" tread depth helps reduce irregular wear on free-rolling axle positions
- Outer shoulder decoupling grooves allow outer tread flex, reducing uneven second and fourth rib cupping wear for even tread wear and long tire life
- Tread groove stone ejectors help prevent stone trapping and drilling, enhancing casing integrity and retreadability
- Sidewall protector ribs help prevent sidewall scuffing and damage
- Reduced weight helps deliver better fuel economy and lower FET than deeper tread tires
