I'm one of the lucky ones that have always had good luck with Goodyear Marathons, 205/75/R14.. I had a 4 year old set on my boat trailer that finally started to give way later last year. My travel trailer now has them and they have yet to give out. People seem to hate on Marathons but I've had nothing but good luck with them. Carlise is good too
A lot of the newer ST tires are now rated for higher speeds. I think the government changed the requirements.
Be careful using LT tires. Check the load rating and be sure you have some reserve capacity.
Leaving tomorrow for Richmond VA. for the NASCAR race. Got to thinking Monday that my tires were almost 4 years old. About time. WalMart advertised on their website Carlisle Trail HD 235 80 16 LR E for $77. Discount Tire matched it. Speed limit on sidewall is 75mph.
