It's Better to be 5 to 10 lbs over inflated rather than 5 to 10 lbs under inflated.....Your coach will actually track and steer better (turn easier) when the front steer tires are slightly over inflated... Most older coaches are overloaded or at capacity when traveling, if they don't have a tag axle.

Doesn't everyone have a copy of Michelin's RV tire guide www.michelinrvtires.com/assets/pdf/RV_Brochure_June2009.pdf in their maintenance files? It is very clear on evaluating tire condition, life, pressures, loading, etc.

I don't carry that guide, but I do carry the page from the Michelin web site for the tires on my coach. I also have three weight tickets, one with ALL tanks full, and two collected at "traveling weight" after filling with diesel fuel during trips.

On the coldest day I encounter, whether at home or traveling, I check the tires and set them to the recommended pressure from the chart that is just above the maximum axle weight I expect based on the weight tickets. As ambient temperatures rise, the "cold" pressure will rise 1-2 psi for every 10F increase in ambient temperature. I don't normally release any air to lower the "cold" pressure after temperatures rise. I expect to have to add air next fall or winter do to falling temperatures and the normal leakage of some air through the rubber.

After setting the appropriate minimum , I periodically check the pressure to verify that all the tires are "tracking" each other, i.e., no tire is losing air due to an abnormal condition. I also check tires by "bumping" them, and checking them with an infrared sensing thermometer at almost every rest stop. I figure I will be at a "safe" pressure for any conditions and be using a pressure appropriate for safety, comfort, and performance.

It appears that participants here are trying to be safe and learn. That's cool!

Having the Pressure Pro system, I found the tire pressures do raise more than I expected from stone cold to hours on the road, have not had this system in the heat of the summer yet, but so far have seen pressures raise 10 psi while driving, I keep the cold pressure at 110 front, 105 on drive. Learning is an experience.

Pressures will rise whenever the temperature of the gases (air) in the tire rise. Boyle's law describes the the relationship among volume, pressure, and temperature. TPMS gives readings as while you are driving the demonstrate the changes.

In a static situation (parked), I can measure pressure differences between the sunny side of the coach and the shady side. The pressures are the same before the sun illuminates one side. During a rest stop on a very windy day, I could measure higher surface temperatures (implying higher pressures) on the downwind side of the coach even though the sunny side was on the upwind side. I inferred the extra loading from the wind pushing the coach to one side loaded the tires more, causing more heat and higher pressure. Tire pressure is dynamic when the coach is in motion. Setting the pressures while "cold" and stationary provides good conditions for consistent, appropriate measurements.

Just as information, I had a CrossFire assembly installed on each set of duals a couple of days ago in Oklahoma City. While there, I asked approx. what the cost is for a new set of tires. He said figure $4000 for BF Goodrich and close to $5000 for Michelins. Those are the two brands of truck tires they sell. He said he knew the price of the BF Goodrich as they had just installed a new set on a coach that day. (In fact, the coach, a Foretravel GrandVilla was backing out just after I pulled into their lot.)

Morris, I bought my coach tires from T&W Tires, 25 N. Council in OKC. This was 2009/2010 but BFG's were under $3,000. You may wish to give them a call.

I am currently pricing tires in the Tucson area for my son's 98 U270
As we use our tires off road quite a bit I have been using the Michelin XZA3 275/80R22.5 LRH
Due to lack of availability (2 months) of that tire I researched other brand with similar quality and have gotten a quote from a couple of places. I will share all of them when time permits.
I have not gotten a good quote yet on Goodyear (prices seem to be much higher so far) G399 and G395
I am now looking at the Bridgestone R-287A in a 295/70R22.5 LRH as it compares favorably with the XZA3
Tire: $584.00
FET: $34.59
Scrap fee: 9.99
Balance Fee:24.99
Sales tax: 7.7%
Recycle fee: 2.00
He has not yet seen my casings or committed to a price for them.

The total of the above for six tires is 4327.20

Is anyone using the above tire?
Comments on the different size charateristics? 275/80 v/s 295/75

Biggest problem so far is that everyone wants to sell what they have in stock regardless of what you want installed. They all seem to be selling based on price rather than the quality of the tire for the job. I've been offered a heck of a deal on Chinese Hankook but, I don't think I want to go there..

More quotes later....

Regards,

I will definitely do that... Thanks very much Kent. From what I have read, it appears the truck tires are really going up right now.

We put Michelin XZA-1+ 275/80R22.5 LRG on a 1997 U295 about a year ago. Total price installed was about $3,162. According to Michelin charts, the tire is adequate for weights up to the maximum safe axle weights for the coach. We normally operate at about 1,300# below front GAWR and 1,600# below rear GAWR with full fuel, full fresh water, us, and our stuff. We bought the tires from Herman Power in NAC.

Hi Jon,

We have had Toyo (made in Japan) tires for just over a year now and really like them. But, with 8 air bags and Koni FSD, I think I would not notice much difference in any brand of tire.

Anyway, we are using M154 in Load Range H.

They are substantially lower in price than Michelin. And when one tire turned up with a chunk of tread missing about the size of half a golf ball, Les Schawab gave us a new replacement tire under the Toyo warranty about 4 months after the sale date.

Just got 6 tires for U295 40 ft at Powers on the 20th. He installed 275/80R22.5 H Mich XZE
$536.10 each
mount $25.00
Balance $25.00
Trade in of old front (yr 08) TOYO tires (2) rear tires were too old for trade (01 and 02)
minus $400.00
Sales tax $232.37
Drive out $3348.97
I think Powers in Nacogdoches is very fair on their pricing. He had the tires on order for three weeks and they are 02/11 dates. He indicated the Michelins are getting harder to get and the price keeps going up.
Dan Stansel U295 40 02 and U270 99 36 for sell

Check into Loves truckstops,most of them deal in tires. I was surprised the prices were reasonable and will deal when you buy more than one at a time,also may buy your old casings if good. BFG tires were a good buy.

They have a good reputation and a good following. The local Hankook distributor here is high priced. Can get Goodyears at the same price as he wants for the Hankooks

someone once said that we should list brand, size, price etc so there was a good comparisson.

Ok, just 2 hours ago, installed 6 Bridgestone 295/75R 22.5 R280 @$400 each + $120 mount dismount etc. $2520 + tax. They quoted $2664 and that's what I paid out the door. The DOT dates is 0911 so they are less than 4 months old. Sold 5 minutes ago, my old Michelin for $100 each for a total of $600. Final price for my new tires $2064 and I am a happy camper

An added bonus, the tires are R280, the coach is U-280

Carl,

Great info. Thanks. How old were your old tires?

Seems tire prices are going north on a weekly basic.

Well, I thought I knew what the DOT date meant -- the month and year of manufacture. If that is correct then your tires are due for manufacture four months from now. Can I assume that you meant 0111? If not, what am I misunderstanding about DOT date?

Paul,

The last for digits of the DOT... number which is molded into one sidewall of each tire indicates the WEEK and YEAR of production.
