Use Of Front Tires With A Different Profile Effects The Travel Speed Indicator {4203}

Usage:

RR-250 Road Reclaimers, SS-250 Soil Stabilizers

RR-250 Road Reclaimers and SS-250 Soil Stabilizers are available with a travel speed indicator group. The travel speed indicator is gear driven off the drive shaft. This gearing has been calculated based on the static loaded radius of the standard recommended tire. Use of front tires with a different static loaded radius will reduce the accuracy of the travel speed indicator.

The standard tire for the RR-250 Road Reclaimer is a Goodyear 23.5-25 E2. This tire has a static loaded radius of 706 mm (27.8") when loaded to 6300 kg (14,000 lbs) per tire at 310 kPa (45 psi). The standard tire for the SS-250 Soil Stabilizer is a Goodyear 28L-26 R1. The static loaded radius is 706 mm (27.8") when loaded to 4950 kg (11,000 lbs) per tire at 165 kPa (24 psi).
