Well, I have surfed all the treads about tires. Today I went down and put two new steer tries on my coach. I had ment to get the Bridgestone R250 or the R280, until I was told they have been back ordered and hard to get in 295/75/22.5. So, I ended up with Firestone FS590+. I am replacing the G670's that I had up front, the ride and handling was very noticeable from the moment I pulled out onto the road. I drove home on some pretty rough roads, about 25 miles, so far every excited that I went with them. They cost $443.00/each mounted and balanced. Thanks for all the info.
