Yes, Chris, the Maxxis ST225/75R15 Radial Tire w/ 15" Black Modular Wheel - 6 on 5-1/2 # MXS99FR is built for standard 6 on 5-1/2 inch hubs, which are found on most 5,200–6,000 lb axles. Each assembly is rated for 2,830 lbs at 80 psi, giving you over 11,000 lbs of combined capacity on a tandem setup with 4 of these installed. It’s a perfect fit for mid-size travel trailers or cargo haulers.

Do you know your current tire size and load range? I can confirm if this is an exact match or at least an upgrade.
