17.5 Inch Trailer Tires and Wheels
17.5 inch is the commercial step up from 16-inch trailer wheels, used on heavy equipment haulers, dump trailers, tilt decks and goosenecks running 10K to 12K and heavier axles. This page has every 17.5-inch part we stock: HPD HDT forged aluminum wheels in hub-centric and lug-centric versions, black modular steel wheels, all 17.5x6.75 with an 8 on 6.5 bolt pattern, and 215/75R17.5 16-ply and 235/75R17.5 18-ply tires already mounted and balanced on them.
Orders ship from the U.S. with tracking. Lug nuts and center caps are sold separately.
Common questions
Hub-centric or lug-centric?
Look at your hub. A raised machined pilot in the center that the wheel bore sits on means hub-centric. A flat hub face means lug-centric. The 235/75R17.5 assemblies here are hub-centric and the 215/75R17.5 assemblies are lug-centric; the bare forged wheels are listed both ways.
Can I switch my 16-inch trailer to 17.5?
If the axle is 8 on 6.5 and the fenders clear a tire about 30 to 32 inches tall, yes. Replace all tires and wheels at once.
Why 17.5 instead of 16-inch load range G?
Commercial 17.5-inch tires carry more per tire, run cooler and last longer under constant heavy loads. If the trailer works every day, 17.5 is the better long-term buy.
