Sumitomo 5534000 ST538 Commercial Truck Tire 11R22.5 16 Ply

The Sumitomo ST538 is a commercial truck tire designed for all-position use in mixed on/off-highway service. This medium-duty truck radial is engineered specifically for on/off-highway mixed service applications, making it ideal for delivery trucks, refuse haulers, and construction vehicles that encounter both paved roads and challenging terrain.

Key Features:

• Deep tread depth and application-specific tread compounds contribute to long wear and reliable performance
• Uniform tread depth and smooth block edges help prevent irregular wear
• Stone ejectors help protect the tire casing from damage in the base of the groove
• Thick curbing ribs help shield the casing from sidewall damage
• Application-specific tread compounds resist tread chipping in high-scuff on and off-road applications

This tire features a tubeless (TL) construction with a 16-ply rating for exceptional durability and load-carrying capacity. The 148/145K service description indicates a maximum load capacity of 6,940 lbs per tire at maximum inflation pressure, with a speed rating suitable for highway use. The black sidewall (BSW) design provides a professional appearance for commercial fleets.

Backed by Sumitomo's 6-year/2-recap warranty, the ST538 delivers outstanding value for fleet operators seeking reliable performance and extended service life in demanding mixed-service applications.
