Yeah, I'm seeing that no RV is perfect. I learned a new word today: China bombs lol
This is the best way to go on the larger double axle toyhaulers for tires. Not cheap entry fee but will have long term life and reliability. Plenty of choices for 215/75R17.5 LR F, G, or H that are 75 mph rated if needed. For 7K axles use G or H to get a health safety margin.
Figure G rated 16" or ST Class E or F rated 16" will need 3 to 4 year life-cycles and 17.5 to have 6 year + life-cycles. The ST tires are a******shoot of reliability IMO especially in high ambient temperatures and max load operating conditions.
