Looking to buy 6 new tires for my class c,What is a good all aroung tire,I've been searching on here and it looks like Michelin is a real good tire,this is my first motorhome and I've had it for a little over a year,It says on the tire It's class E rating,Should i stick with that ? or look for something else,I would like to get a little smoother ride,I just put 4 new Bilstein shocks on it and that helped a lot. Any suggestion? Thanks Ron
