The new 35×10.50R15 KR2 SXS/UTV and the Class 10 in the same size, should not be ‘mixed’ in use on a vehicle, as they were designed for different platforms and weight distribution.
The KR2 UTV tire offers superior performance and increased mobility in soft soils, enhanced traction in mud and improved braking in loose and rocky soil. Images below, same tread pattern, differing dimensions.
