New Tires

I have had many brands on my coach and Michelin have been the best. However, BF Goodrich and Michelin are the same tire. Look into the FMCA discount and look at the BF Goodrich brand. That will be my next new tire(s).

I blew two tire a year ago on our 2011 same trip different days. They were Goodyears OEM. Its a lot cheaper to replace with Michelins on a planned basis than have a roadservice deliver a generic. And if you want a thrill, blow a front tire at 65 mph in traffic.

I currently have 38k miles on our class A 2011 38' MH.
Question I have, is how to determine when to replace the tires?
All the tires have even wear. Have had a tire rotation, balance, and alignment every year. Tires are Goodyear 19.5" RV670's.
There appears to be a "rib" in the middle of each tread. At which point in depth should I consider replacing the tires?
Thank You for any feedback.

I finally took the plunge and put six new tires on the MH last week. I got the Cooper Roadmaster RM170. The dealer put 100 psi in the tires and I am feeling like they are overinflated. I feel like I do not have the control I was used to on the old tires. I ran 90psi in my old Michelin's. I would like to hear what others have to say about tire pressure. I am considering letting some air out and giving that a try on the next trip.

If they are the same size and load rating as the old tires, they would require the same inflation pressure as well.

Standard and proper practice is to get actual axle weights for your rig with it loaded (unless you know that information already) and inflate based on the tables the tire manufacturers put out for the load on each axle. Anything else is at best a guess. Typically the tire pressures listed on the placards the manufacturers put on vehicles are based on maximum gross and axle weights and so may be unnecessarily conservative for actual use. They also would only apply to the stated size and load rating of tires.

I am really lost on what tire to buy for our Coach. i had the Toyo M154s they rode great first few years and got hard. My wife says gotta have tire that rides smooth, I told her that is a tall order when looking at a 38ft coach and crappy roads. I looked at the Yokohamas and they talk smooth ride and run about $2200.00 for 6 compared to $3600.00 for 6 Bridgestone. I dont mind paying for a good tire, but price doesn't mean they are the best. Can anyone shed some light on the tires 265-75R-22.5

Today I looked at Cooper Tires...Roadmaster RM170. "H" rating and the price was half the price of the Michelin tires. Anyone have any Cooper tires on their MH? I hear they are made in China and run a little stiffer than other brands.

Been running Bridgestone tires on our coach for past 14 years, great tires no problems with them over the years. Highly recommend them.

Good luck with your choice and safe travels.....

Thanks to everyone for all of the great information and advice. I will broaden my range of tires to include the brands mentioned in all of the posts.

B F Goodrich if you're selling. They are good tires, owned by Michelin but are much cheaper. We had BF Goodrich ST230's Load range H on our Class A and were very happy with them. We bought Michelin's this time because of a bit softer ride. You can check with FMCA to see if BF Goodrich is included in their discount program. I think they are.

Yes, the FMCA Michelin program includes B.F. Goodrich tires.
