When I had the Chevy Kodiak 4500 I ran Michelin tires, now that I have a Freightliner I'm running 22.5's for steer tires and they are Toyo's and the drivers are Sumitomo. Both type tires are wearing great. If I ever have to replace the drivers I will go with the Toyo's. The Toyo's have never been balanced and there is no vibration at all. I don't undertand the need for 19.5's on a 1 ton Truck?. I see were Ford aren't going to be using the 19.5's on the 2011's? However the Michelins are great wearing tires but are very Pricey. I paid $285.00 per tire for the Toyo's. Good Luck on your choice. GBY....
