Our 5th wheel (see signature) came with LT235/85R-16G Goodyear Unisteel G614 RST tires, and they are great in trailer service. They run as cool as the LT235/85R-16E Michelin XPS Ribs I ran on my previous 5th wheel.
A couple of thoughts:
1. The G614 is a G-rated tire (3750 lbs @ 110 PSIG). Are your current wheels rated for 110 PSIG? Note on the upcoming website link that Goodyear stipulates that a special wheel is required, and the wheels that came on our trailer have a much thicker cross-section than comparable 80 PSIG rated wheels.
2. I really don't know about the traction, handling and ride of these tires in a Class C application - as the website link below shows, these are trailer-specific tires according to Goodyear - at least that's what they say here. That seems to conflict with the other Goodyear website data you found, so
