Frequently Asked Questions
Q: When should I use SU S9117-XL instead of the standard SU S9117?
A: Use SU S9117-XL when your truck is rated for heavy duty service or operates in harsh conditions. XL wheels have reinforced hubs and heavier duty bearings rated for higher load capacity and extended runtime. Check your truck nameplate - if the load class is 2500 pounds or higher, or if you operate 24/7, the XL version is required. Using standard S9117 on heavy duty trucks voids warranty and causes premature failure.
Q: Is SU S9117-XL compatible with trucks that use standard S9117?
A: The bore diameter and dimensions are identical, so physical fitment is the same. However, you must verify your truck axle support can handle the XL wheel weight and load. Heavier duty wheels require heavier duty bearings and seals. Check the truck manual or contact the manufacturer before upgrading. Using XL on undersized axles causes bearing wear and truck instability.
Q: Can I mix standard S9117 and S9117-XL on the same truck?
A: No. Never mix standard and XL wheels on the same truck. Mismatched wheels cause uneven wear, steering problems, and increased bearing stress. Always replace complete sets or pairs with the same part number. If you have mixed wheels on your truck, replace all four wheels with matching SU S9117-XL units immediately to prevent accidents.
Q: What applications require the XL rating?
A: SU S9117-XL is required for 24/7 continuous operation trucks, heavy warehouses with constant loading cycles, outdoor or rough surface use, and trucks rated above 2500 pounds capacity. Retail or light warehouse use typically does not need XL. Always reference your truck load class, duty cycle, and operating environment to determine if XL is necessary. Upgrading for no reason wastes money but upgrading when needed prevents downtime.
Q: How long do SU S9117-XL wheels last compared to standard wheels?
A: Under the same conditions, SU S9117-XL typically lasts 20 to 30 percent longer than standard S9117 due to reinforced bearings and hubs. In heavy duty applications, XL wheels may reach 2000 to 2500 operating hours versus 1500 to 2000 hours for standard wheels. Extended lifespan justifies the higher cost if your truck operates heavy duty. In light duty use, both wheels last similar time.
