Many people regard Michelin as the best tire for the application.
They are also the most expensive. Having said that if you follow the link below to the Family Motorcoach Association you will see they have a discount program on Michelin Tires.
The membership price to FMC would be recouped in discounts on one tire. If you join FMC the discount will bring the Michelins down to a price very close to the lesser regarded options.
