In the line immediately below, with the same size 295/75R22.5 tire -- but apparently these are the G rated tires. It shows only a load of 5780 lbs at 100 psi and specifically says the load limit for G tires at 110 is 6175 lbs. To me, that says if I need 12000 lbs on the front axle I would have to inflate a G tire to 110 psi (max) and if I had an H (which I do) I can run the H tire at 95 psi and carry 12000 lbs. You can call me a moron (my DW does all the time) but that's how I read the table.
IIRC those two tires are Euro spec tires. Which is why I said in most cases.

But I will confirm with BFS. Stay tuned for updates.

Dear "Confused"--now I am too, but that tends to be my normal state. So here is what I learned today--early Alpine coaches have 10.5k front axles, my early 03 actually has a 12k, not the 13k I thought it had--go figure. So here is what I think--weigh your coach [all 4 corners if possible]--then, armed with these facts, you can make a good decision about tires and load ratings.

Study the various load rating tables by tire brand so you can get a good comparison of tire sizes vs tire pressures, and resulting recommended/max load. Shorter coaches [34s&36] along with earlier model coaches might/probably can do just fine with G-rated tires. Longer/newer coaches with combined axle weight of 33k should go with H rated tires--IMO.

On longer/newer coaches, if you are carrying max weight, and manage to get into a really strong cross-wind on very hot day, I suspect you could exceed G-rated tire specs on your front leeward corner. I have blown one G-rated tire on the front, I have not blown an H-rated tire--not yet anyway. Realize this is not a statistically significant sample size but for the modest difference in price--I dont want to ever again have the internal debate with myself about whether the G-rated tire contributed to the blow-out.

i am in the market for new tires for my 2004 36' fds. my previous 2 motorhomes had Michelin tires and i much preferred the way they drive compared to the Toyos. much less tracking in freeway "troughs". however, i have had 2 flats with Michelin and none with the Toyos. one of the "flats" was a right rear sidewall blowout with no visible damage. however, i confess to probably hitting things with that tire, which i think is what is largely thought to be a weakness with Michelins. However, i also talked with a retired Michelin dealer and he said the problem is also that that tire has much more pressure put on it with tight right corners and that that is also a cause of problems??

any thoughts on the driveability issue, or am i the only one experiencing this issue??

I have been running the Michelin's for 3+ years with no flats. I would have to check my records, but that is probably at least 25K miles or so. But no flats with the Toyo's that came on the coach either. I keep mine on the high side of the inflation range, if that makes any difference. And I have tire pressure monitors now with the Michelin's, so they never run low pressure.

These are the 11R22.5 H rated tires.

I would get them again. (If my wallet can take it.)

Need to replace Toyo Tires

I have a Alpine Limited, 2005 with 44,000 miles. My tires are due to be replaced (al
l are 04 tires). Currently run M120Z, 11R22.5, load range H, 16 ply. A dealer quoted me $550 per tire +tax and installation. Is this a good price?

Are you an FMCA member? If so you can use the fairly new agreement between Michelin and FMCA to buy tires at quite a discount. Details are on the FMCA site.
I bought mine before the agreement and I paid $500 for 275/70 22.5's mounted and out the door. The front 305/70's were $612 each mounted, balanced and out the door.

I had a set of TOYO on my old MC. HATED them. The were hard and they transfered that hard ride thru the whole coach. they may be great on a semi but they were GOD AWLFUL on the MC. Purchased them for 2500 in FL. Replaced them with Goodyears and the ride improved. the GY cost $3200. I didn't save an ything. ed

I weighed our coach some years ago. The front was 9720 lbs and the rear was 16520 lbs. I am pretty sure that was with full water and probably full fuel. The factory numbers in the brochure are 12,000 front and 19,000 rear. I put on Goodyear G670s, H range, and looked at their load chart for tire pressures I would run. I chose 95 front and 90 rear. That gives me a capacity of 12,570 front and 21,340 rear. The original Toyos did cup on the front tires, as mentioned earlier; the Goodyears not so much. They have slight cupping, but nothing like the original Toyos. I put the Goodyears on at 30,000 miles (June '06) and presently have 73,000 miles on the coach. By the way, I had the passenger front tire blow out on me on the way to get the six new Goodyears installed I will likely be putting new tires on next year and I am not looking forward to the higher prices I am hearing.

Toyo M120Z 11R 22.5 Tires

Check with tire dealer last week and he can get this tire for me special order for $550-580 range + I will need to find someone to install them.

Another tire dealer this morning said they will install them for $28 + $6.95 for valve stem.

Dealer could not get the 120Z tire but could get the M147 16 Ply, H load range Product code number 547330 for a total price of $526 per tire minus my casing rebate. This tire is same height, but has a 19/32 tread depth which is 2/32 more than the M120.

Does anyone have a comment or opinion!! IS this tire ok or should I pay the $75 more fpor the 120Z. Thanks

Doesn't sound like an overly good price to me for Toyo's. I got top of the line Michelin's mounted and balanced for about $600 a year ago. That was for the 11R/22.5 size tire, H rated.

FMCA Michelin Tire Discount

I'm in the market for new tires and went to the FMCA website to inquire about the discount they give members. I was not impressed with the example prices they showed. Has any one used the program and got better deals than you can get by bargaining with a tire dealer?

Angry

Unfortunately prices have gone up again this last year about 20-24%.

Jr, the Toyo 154 is a steer tire. Unless you are traveling long freeway distances, the Toyo tires of my choice would be the 120 or the 154, both all position. The 154 has 22/32 of tread, and is comparable to the Bridgestone R260 that I run.
