315/80Rx22.5 Tires

Yahoo Message Number: 29775
I've been searching the CC and Michelin/Goodyear sites for info on 315 tires for the front of my 2001 Affinity and for 295/80 tires. I can't seem to find anything or dealers who carry this size.

Pls advise as to where/how I can search to find this info. I'm in Naples, FL now and will be traveling north to Raleigh, NC. So if you know any dealers or can provide info on where to replace my tires.
Also I'd appreciate any info as to your experience/recommendations with Michelin and Goodyear tires.

thanks, Denny Zarnt 2001 42' Affinity #5972

Hi Denny

Guess you are back from your cruise. We need tires too and Ned Hermann, who lives in Naples and was at the Jekyll rally, told me about Callaghan Tire at 5791 Taylor Road in Naples. Taylor runs north off of Pine Ridge and connects Pine Ridge with J&C Blvd. It is between Goodlette and Airport. The shop was hard to find and will not win any neatness awards! Use the street address and look on your left as you are going from Pine Ridge toward J&C.

I stopped in there about two weeks ago and talked with Mike Jackway about 12R22.5's for my coach. He carries Michelin but not Goodyear. Offered me Bridgestones Metro All Position Ribbed Radial as an alternative to Michelin. All in price for the Michelins was $655 and $626 for Bridgestones. Both seemed higher than what I have read on this board, so I was going to do some more shopping.

When are you heading back north? We are stopping in Palm Beach tomorrow and Tuesday and will be back in Naples on Wednesday. If you are still there we can go tire shopping. What fun!!

Denny,

We replaced the original 12R-22.5 Toyos on the front last May with Goodyear G670 RV tires, size 315/80R-22.5. The new tires ride a lot softer, as I was able to lower the pressure from 115 psi to 95 psi and still carry the same load. We got ours at Les Schwab in Junction City.

I had been running my '95 Magna with Toyos on the front at 100#. When I had the G670 tires installed on the front, the guys at the Oklahoma GoodYear dealer went whacko on me when I said I wanted them inflated to 100#. They said a minimum for this tire should be 105# and they would rather I used 110#. I currently run at 105.

Still softer than the Toyos.

Hi Brad:

I'm interested in the inflation numbers you posted.
Did the folks at Les Schwab agree to the lower pressures and airing to load? The reason I ask is Jon Edwards, manager at the Junction City Store, was adamant at the Jekyll rally that all tires should be inflated to the plackard pressure regardless of load.
Are they singing from a different hymn book?

Our Toyos were replaced with G670 RV tires last summer by CC to address a recall concerning incorrect inflation pressure labeling. CC shipped them to Les Schwab and insisted on 115 psi in the front and 105 on the rear (duals). The original inflation was labeled as 105 all around.

I only have the ride on the Toyo tires versus the G670 for comparison, but there was a world of difference. The coach handles so much better with this new pair of shoes.

Bob,

We have weighed our Magna several times. The front axle total weight has ranged from 12,400 to 12,780, with the side-to-side difference, with me in the driver's seat of only 20 lbs.
So, with the Toyo 12R22.5 tires, I ran them at 115 psi, giving them a load carrying capacity of 14,020 lbs. Now, with the 315/80R22.5 Goodyear G670s, I am running them at 95 psi. This gives them a load carrying capacity of 13,880 lbs. I see no reason to run them at a higher pressure. These settings give us a good safety margin, and we have not experienced any tire problems, such as uneven wear or running excessively hot. As a side note, after running for 30 minutes or so at highway speeds, all of our tires, front & rear, will be at a temperature 50 degrees above the outside ambient air temperature, as measured by our SmarTire. If it's 30F outside, the tires will run at 80F. If it's 100F outside, the tires will run at 150F.

I have read in the past, articles that have said if the tires are over-inflated for the loads they are carrying, the tires will not have the proper footprint and will wear out in the center, rather than across the whole tread.

As for Les Schwab, they didn't say a thing when I told them to put 95 psi air pressure in them. I think it is just "cover your butt" talk, when these tire manufacturers are telling us now to run all the tires at the maximum pressure they will hold. If you run the Goodyear G670 tire at it's maximum pressure of 130 psi, each tire will carry 9090 pounds as a single. And I cannot imagine what the ride would be like, probably like riding on solid rubber wheels.

Sorry to ramble on, but that's the rationale I used.

Thanks for the info. I'am inclined to agree with you, but if you read some of my exchanges on this forum, you will see I am no expert. So I am always interest in "stress checking" my logic. Like you I think the current advice is CYA and if you ar diligent about airing to load, know your weights and monitor tire temp and pressure, then it seems safe to me. I have tried 120 psi and it is a much rougher ride, at least on Toyos. Everyone says the Goodyears and Michelins ride much better. Most of these arguments, along with your wear argument were offered at the Jekyll seminar but Jon would not come off the "air to plackard" mantra.

Have you weighed your coach front to back and side to side. Take the highest weight of the two front tires and check the tables for correct pressure. Then add ten lbs as Michelin and Bridgestone recommend. It works for a lot of people. TI 2004 Intrigue 11731. If some one out there has a solid axle coach all bets are off especially if you are running 275 R70 tires. They don't handle heat and dynamic forces well. TWI 98 Allure/ 2004 Intrigue 11731

When I was at home comming and service in 00 and 01 at the different seminars about tires and chassis, etc; there was every effort made to make sure the ride height valves were in the new positions with two in the rear and only one upfront on Allures and Intrigues. Then they weighed every coach that had a tire issue and fell under the recall. ie. Allures and Intrigues with solid axle, 275R70 tires, with kitchen slide. Especially 40' coaches.....They readjusted the ride height valves to transfer weight off the left front tire. The left front tire was incapable of handling the dynamic forces (side to side) put on and would eventually fail.. Thus the recall. Even by having the two ride height valves on the duals and thus being able to transfer some of the static weight off the left front tire. Though having corrected the 36' coaches, the 40's had to have 275 R 80 installed to handle the Dynamic stress. Some were found to have as much as 1100 lb, in balance between the left front and right front tires. CC would repack the storage bays, because some 40's were beyond the axle rating on one corner even after adjust ment. Because I had a 36' (900lb difference up front)they changed the ride height valves location and replaced my tires in front on three different occassions with the original size. The original sets either had to be returned for inspection or distroyed. In 02 after still reading about all the problems I had Les Schwab pull the left front tire and after 18 months at 120 lbs, you could begin to see cracking developing on the inside. Now I live in a very hot and dry climate, but the coach is stored under cover. I therefore replaced all the tires with 275R80 Continentals. Two very important things happened. One, I could drop the tire pressue 15 lbs and drive all day without my dentures falling out and two I could run at 65 and drop my rpms out of the gas hog position. Now the Intrigue came with12r's, so the rpms have dropped to the comfort range. I had noticed in my lurking arround that other manufacturers were using a taller axle ratio when using this 275R70 tire so I felt two very important issues had been taken care of. I was very fortunate, I never had a tire blow; I did have one come apart while stored. I was only inconvienced twice, and the cost of the new tires was only 12 months early. One concern I have never expressed is if a ride height valve fails or adjustment needs to be made due to change of items carried on board, is the tech who replaces the valve have the capability or the knowledge necessary to measure and transfer the weight off the left front tire as necessary to insure safety when using the smaller 275 r 70 tire?????? The 12r's have only needed one service and that was rotating the front with the tags, due to light wear developing on the outside edge of both front tires. TWI 98 Allure 30255, 2004 Intrigue 11731..
