The marathons are only good to 65 mph! Above that can cause internal damage to the tire. Don't even think special trailer tires are speed rated like car tires. I had 2 blowouts at less than 8000 miles and I never went over 65...mostly traveled at 60. Of course, I don't know what the delivery driver did from factory to Camping World of Southern Alabama. I was lucky with minimal damage to monty on my blowouts...but the tires were ripped open 3/4 of the way around at the tread/wall interface. John
