We have a 2011 Copper Canyon 273WRET, dry weight 7,800#, GVWR 10,240#, that came with TowMaster ST225R15D tires. This is our 3rd year camping and the RV has about 20,000 miles on it.
I have been looking at tire posts on the forums because I wanted to replace the tires before our long trip to UP this Fall.
BUT, on the way to Memphis (from Georgia) two weeks ago, I blew one of the tires near Huntsville, AL.
Three tire stores later, the tires were replaced with TowMaster ST225R15"E". The tire tech told me the current aluminium rims would handle the 80# PSI, no problem. So I'm happy with the new tires even if they probably cost more than they would have if I had shopped around.
The original TowMaster tires never had a problem until the one blew. I always checked pressure before traveling and did "look arounds" at rest stops, fueling stops and such.
Note: The first place I looked was Costco but tires weren't in stock. The important detail is that Costco doesn't come out to the RV in the parking lot nor is there clearance in the tire shop to bring in the RV. You have to bring in the rims/tires and they will dismount old, mount new.
