Where to find tires ....

[Ray Davis]

Jon, no I haven't weighed the coach yet. I was out of town all week, and now just trying to get going again. The reason I've been looking for the larger tire is:

1. the coach currently has 315/80's all the way around (except for 1 tire which I (mistakenly?) put a 12R22.5 on to replace a tire with slash in sidewall.

2. a phonecall to Prevost they told me that's what to put on the coach

3. (this is a guess here). my coach interior was redone in 1999 and the entire coach (except bedroom) flooring was replaced with tile. I'm assuming that this was a bit heavier than the previous carpeting. The tires on the coach now (1999 tires) are the 315/80's. Perhaps they were put on when the coach interior was re-done?


SO, I had kinda assumed that if the R12 was acceptable, that the 315/80 with it's better load carrying capacity would be better? Handling on the coach at the moment seems to be fine, although I've never driven another coach to compare, but it handles really fine.

So, that's why I started looking for those tires, and that's when I ran into these roadblocks. Several Goodyear dealers told me that there were no G670RV's in my size to be found anywhere in the US. I was looking at the Goodyear, because I thought it would be cheaper than the Michelins, but better than the Toyo's?

I was going to get the coach this weekend, so perhaps I'll be able to weigh it.

I ran them with no problems on my Beaver Marquis and my Liberty has a full set of Goodyears. They give us a good ride and the largest commercial tire ( tractor trailer / commercial bus ) vendor here in southern Va claims that it is the best value & best quality available. I have been seeing ads for tires in FMCA and Motorhome that are formulated to resist dry rot which will extend the tire life. Ken

"I don't admire Jon, actually, I don't even really like him very much. He just copies everything that I do."

Poor Helen. I don't know how she can stand it.

Look at me,
I'm as helpless as a kitten up a tree
And I feel like I'm clinging to a cloud
I can't understand,
I get misty just holding your hand

Walk my way,
And a thousand violins begin to play
Or it might be the sound of your hello
That music I hear,
I get misty the moment you're near

You can say that you're leading me on
But it's just what I want you to do
Don't you notice how hopelessly I'm lost
That's why I'm following you

On my own,
Would I wander through this wonderland alone
Never knowing my right foot from my left
My hat from my glove
I'm too misty, and too much in love

My only reason for beating that drum about weighing the coach is regardless of whether you need 12R or 315 you must inflate the tires based on the weight it carries.

For example, my old coach required 108 psi on the front axle, 85 on the drive and 70 on the tag. Those pressures came right from the Michelin site and were nowhere near the weights Prevost publishes for tire pressures. I imagine all manufacturers have their pressures posted.

If you get it weighed you also will forever put to rest any speculation about if you need the larger tire. Your coach may be perfectly fine with the 12R tires that it came with. And just to put a fine point on this issue, if your weights are so much that you must have a 9000 pound tire instead of the 7400 pound 12R, then you have a bigger problem than needing tires. You are likely in excess of your axle weights and can anticipate ongoing problems with bearings, brakes, airbags, etc.

Ray,

Ignore the guy who is singing songs. He missed his meds this morning.

You told me it was OUR song!

[Jerry Winchester]

I guess that's the problem I face trying to get low enough to own one. But that psychohomolatenetessenceofwhorehousecasinochic interior and paint really gets me going.

[Ray Davis]

Jon, I agree. I will get the coach weight, hopefully this weekend

Your coach may be perfectly fine with the 12R tires that it came with

You may indeed be correct. I have no evidence that there were ever 12R tires on this coach. Original paperwork from Country Coach doesn't say, and I can't find any paperwork anywhere in what I received that told me about tires. I'm only going by what was on the coach when I received it.

Ray:

All kidding aside, if you are going to make the significant investment in tires, the best thing to do is to work it from the ground up.

Weight
Tire specs
Budget

A long time ago a guy put the tire thing to me this way:

You are going down the road at 70 mph in a 25 ton bus with eight square feet of contact with the road. Is this where you are going to try to save money?

If you put it that way, it helps with the decision.

Please excuse our kidding around, you are trying to find out some very important information.

Welcome to POG!

Agreed. Which is why I've been trying to find a dealer which has either the Michelin or the Goodyear G670RV available.

Prevost has tires (Mich XZA1) available at $678 for the bare tire. Camping World indicates they sell tires and have the same tire as above, for $619 installed. This leads me to believe that I can find these tires for somewhere around $600+ installed??

By the time I'm done at Prevost, I'm looking at $750 per tire, installed. I just think I should be able to do better than that.

I just don't understand why these tires seem to be so scarce. I'm going to try a charter bus company, and see what they say, as suggested by others.
