Tires for the Cougar

Thanks Jerry/goducks10 for the feedback. My analysis was quantitative. Your feedbacks were qualitative albeit worth looking into. Will take your comments and do more research. Interesting spec: the Goodyears (highest prices of those I compared) had 28% less tread depth than the Trailer King.

As others mentioned tread depth isn't a big thing with most RV folks as many have reported maybe 5k-7k miles in 4-6 years of service. The tire works fine in that scenario.

Keep in mind ST tires are used on non rv trailers also.

Tread depth is very important to a operator with trailers in commercial service where we may run 80k-90k miles a year.
A ST D and E tire may have 9/32nds of tread depth and some have been lucky to get 18k-25k miles before the tread is gone in this type of work. Most serious haulers don't use them......can't afford them.

This is where a LT tire or the 16" ST Load G commercial grade tire with 15-16/32nds of tread depth makes a huge difference in miles of service. I've ran LT tires up to 65k miles on my trailers in service. Another plus for this type of work is the tire runs cooler with the deeper tread.....and runs hotter as the tread wears down closer to the tires carcass.

Sometimes lay persons out here on the road using tires in a load carrying position day in and day out find different results than tire manufacturers adds/tire mfg engineering says.
