I recently bought a 1990 Regency Deisel Pusher. It was advertised with excellent tires. This is my first RV and yes... the tires did look good. But... the tires are ten years old and I have since learned that the tires are mored than likely aged out and a new set will likely cost over $3000. What a bummer!!! The coach needs six tires, but was thinking of buying only four. Two for the front and one on each side for the back duals and keep two of the old tires on. Any problem doing this???

Ever seen the damage a tread does when it leaves the tire at speed?

As far as the rear tires are concerned it is not a good idea to mix tires of different wear on one side. For the same reason it is important that both tires on one side are inflated to the same pressure. Any difference in diameter, even slight, can cause imbalanced loading of the two and will accelerate wear and, from all that I have read, is not recommended. Many people replace tires in pairs. The new ones go on the front and the front tires are paired up and put on one side at the rear.

I am also faced with buying six tires. My front tires are eleven years and the four rear are over seven years old. I had a tire on my wife's car develop very bad bulging even though they had less than 30,000 miles on them. They were over six years old at the time.

If you are a member of FMCA they have an agreement with Michelin to get your tires at a good discount. How much discount I have yet to find out but from what I hear it is well worth taking advantage of. Check out the FMCA site for details.

Thanks for the great advice. I definitely will not mix tires based on your post. Just hate to spend so much money on tires. I will check out the FMCA site.

in the worst case buy two steer tires first and wait a few month with the rears.

What size tires?

It's worth it to shop around for tires. I found a local bus company that offers much better prices than I could get from a tire dealer because they buy so many tires. Good luck!

Call,Bobby Henard at:http://www.tractorhouse.com/Dealers/Detail.aspx?cid=3087354, and ask. He maynbenbetter than $440

Its too late. I had the tires put on yesterday for $3065. This included mounting the six tires... 265/75/22.5 Yokohama. They did not do the balancing as I already have a Centramatic Balancer ring on each wheel postion. I am new at this so I have a question.... Were they correct in that I did not need to balance the tires?

Also... they put 100 PSI in each tire. I seem to remember they should be 110 PSI. Am I correct?

we have Centramatics on the semi truck and the Barth. No balancing needed. Yokohama are good tires, got them on the drive axle on the truck and after 265'000 miles and Centramatics they are still good.

When fully loaded with both of you seated, weigh each corner. Then use the Yokohama chart for your tire. If one wheel on an axle is more loaded, air the other wheel on that axle the same.Adding ten pounds to the chart is OK if the wheels are rated for it.

If it makes you feel any better, the 315/80R 22.5 Michelins on my Wanderlodge are running nearly a grand each now. Can't wait to replace these in a few years, OUCH!!! Oh yeah, times 8!

Sears sells Chebby tires (8.00/R19.5 Bridgestones) for about $265. Good enough for the girls I go with! I might get a pair for my front end later this year.
