Frequently Asked Questions
Q: What does the TSW tread pattern provide, and why would I choose it over X-Groove?
A: TSW (tread surface wave) is a subtle wave or ripple pattern across the tire face that improves traction on smooth concrete without creating discrete grooves. It delivers comparable grip improvement to X-Groove but with even lower noise and a more aggressive appearance. TSW is preferred in applications where noise concerns are critical (overnight warehouse operations, customer-facing facilities) or where aesthetics matter. The wave flexes and provides micro-traction while maintaining a closed contact patch for reduced marking and dust generation.
Q: How does Cushothane EZ 85A compound differ from standard polyurethane in the SU 13X5.5X9.5-TSW-EZ?
A: Cushothane EZ 85A is a proprietary elastomer with lower durometer (softer) and lower rolling resistance than standard polyurethane. EZ signifies easier installation (lower pressing force required). The 85A durometer provides better compliance on rough concrete, extends tread life, and reduces vibration transmission to the truck and operator. EZ compound is formulated as non-marking, meaning it does not transfer color or residue to polished floors under normal operating loads and speeds.
Q: Is the SU 13X5.5X9.5-TSW-EZ a direct replacement for my existing 13x5.5 tires?
A: Yes, provided your current tires are press-on (solid-mount) with a 9.5 inch rim diameter and your truck hub is designed for 13 inch OD tires. TSW-EZ is a drop-in replacement requiring no modifications. Remove the old tire assembly using a tire press, clean the hub thoroughly, and press the new TSW-EZ assembly onto the hub using standard press procedures (10 to 15 tons of force). Verify runout with a dial indicator before returning the truck to service.
Q: What symptoms indicate the SU 13X5.5X9.5-TSW-EZ needs replacement?
A: Replace when tread depth drops below 3/16 inch, measured with a tread gauge. Visual indicators include visible flattening of the wave pattern, cracks in the compound, or discoloration suggesting rubber hardening. If the tire slips noticeably on level floor under loaded operation, the compound may be degraded or the tire may be separating from the core. Cushothane EZ compounds typically remain serviceable for 2000 to 4000 hours depending on load cycle and floor surface. Indoor warehouse use on smooth floors extends life; rough outdoor surfaces accelerate wear.
Q: What installation procedures and safety precautions are required for the SU 13X5.5X9.5-TSW-EZ?
A: Installation requires a hydraulic tire press rated for 10 to 15 tons, dial indicator for runout verification, and proper safety equipment. (1) Clean the hub bore and drive shaft free of rust and contamination. (2) Position the tire and core assembly centered on the hub. (3) Apply steady, even press force, monitoring for binding or tilting. (4) After pressing, verify runout is within 0.050 inches using a dial indicator. (5) Do not exceed 20 tons of force, as this distorts the core or tire bead. (6) Wear safety glasses and ensure the press is properly anchored. If you lack a suitable press, contact a tire service center for professional installation.
