Frequently Asked Questions
Q: Is the SU 13 X 5.5 X 9.5-TSW-EZ equivalent to Crown 121501-342-01 or Crown 79494?
A: Yes. The SU 13 X 5.5 X 9.5-TSW-EZ is a direct replacement for Crown 121501-342-01 and supersedes Crown 79494. It is also compatible with Raymond RA 632-131/015 specifications. All three part numbers reference the same 13 x 5.5 x 9.5 tapered sidewall drive tire with EZ 87A polyurethane. Verify your truck model documentation to confirm compatibility before ordering.
Q: What is the benefit of a tapered sidewall (TSW) design?
A: Tapered sidewalls provide a gradual transition from the tread to the rim, improving load distribution and reducing sidewall stress. This design resists chunking and sidewall separation better than straight-wall tires, extending service life by 10 to 20 percent. The TSW design is engineered for Crown and Raymond lift trucks operating in high-cycle, high-load environments such as freight handling or multi-level racking systems.
Q: Can I use the TSW-EZ on steer axles, or is it only for drive axles?
A: The TSW-EZ is engineered as a drive tire and should not be used on steer axles. The tapered sidewall and EZ 87A compound are optimized for the higher torque and puncture resistance required at the drive position. Steer tires carry different loads and require softer, more flexible sidewalls for turning. Install TSW-EZ tires only at the front (drive) axle and use appropriate steer tires at the rear.
Q: How does the EZ 87A compound differ from softer or harder options?
A: The EZ 87A is a mid-range durometer, softer than XL (97A) but harder than standard EZ (85A). This provides a balance between tread life and load capacity. The 87A compound offers good resistance to chunking and wear while maintaining reasonable rolling efficiency. If your truck frequently exceeds standard load limits but you do not need maximum durability, the 87A is the optimal choice.
Q: What is the expected tire life for TSW-EZ on Crown and Raymond lift trucks?
A: Under normal duty cycle and load, the TSW-EZ typically lasts 800 to 1200 operating hours before tread reaches 2/32 inch. In heavy-duty environments with frequent load spikes or rough floors, life may be reduced to 600 to 900 hours. Rotate tires every 250 to 300 hours to equalize wear between drive and steer positions and maximize total tire lifespan across all four positions.
