Tire Time? 275/85 R22

The tires on my 07 MH were made in March of 2006. The have 21,000 miles on them. They appear in excellent condition without cracks. When would you replace them? The coach was stored under cover in Arizona. What brand do you like?

Thanks
Mike

What brand tires? I know that the recommendation is to replace, but what about having them inspected by the tire dealer? They might be able to give a good assesment of them.
When we replaced the tires on our last MH, I went with the Firestone FS560. I was not impressed with the Goodyear tires that were on our MH for the road conditions here in Alaska.

Your tires are almost 7 1/2 years old. I would replace them now. I bought Toyo's thru Les Schwab in Oregon and saved about $1300 over Michelin's.

It's a piece of mind issue. Internal tire condition is largely unknowable. Here is what I did when my tires were exactly the age of your tires.
1. I replaced the steer tires then. The steers generally carry the biggest load per tire and are inflated to the highest psi. They also steer and if you have a flat or blowout there is nothing else there to pick up the slack..
2. One year later I replaced the drive axle tires.
3. One year after that I replaced the tag axle tires.
There are many brands that are suitable and that people put on motorhomes. For me, as a full timer, I wanted tires that were reasonably available nationwide so if a replacement tire became necessary, I could find a match easily. I did not consider the only 2 tires that are marketed as RV tires the Goodyear G670 and the Michelin XRV. Both have had issues over the years. I considered the following and looked for all position truck tires.
1. Michelin
2. Bridgestone
3. Goodyear.
I ended up with Michelin XZA2 Energy on the steer axle and Bridgestone R250 on the drive and tag axles.

Goodyear G 670 RV

Thanks all, my current tires are Goodyear G670 RV. 275/85 R225.
I have had the tires aired up at 3 different shops and none have mentioned anything wrong.

I think your size is 275/80 not 85.

Just finished a 3,500 mile trip through the northwest. I was surprised during a fueling stop in Utah to find out that the belts on my front tire were separating.

I'd checked the tires before we left and they looked fine. Without delay, all six were replaced.

Two years ago we were on a cross-country trip with some friends when they lost an inside squally. It tore up the fender well, storage cabinets on both sides of the wheel, and tore out the LP gas lines.

The moral us, don't go by looks. Go with the age recommendation. How much safety are you willing to risk in order to save a few buck?

Common wisdom is at the 7 year mark, that is why I use 10!

Just replaced my 275 80R22.5 Michelins as they were manufactured in 2004. One of them showed minor cracks on the sidewall the others looked fine but I didn't want to play Russian roulette any longer so I bit the bullet.... Bought Michelins XZA3+ for $617.00 Canadian dollars from Robert Bernard Tires here in Montreal. That works out to approx $587USD at today's exchange rates. Obtained quotes from two Michelin dealers in Plattsburgh NY and Burlington VT and both were asking for $100.00 more per tire in US dollars, and would have to be special ordered.... Just wanted to give you folks a heads up as I have read many posts regarding high cost and/or difficulty to obtain Michelins in the US. Cheers

Could also be 275/70 made in G670's But being on a 40'er probably 80's

My G670 275/70/22.5 are now 8 years 4 months old with 33,000 miles.
Plan on replacement at 10 years 2 months.

If yours were Michelin I would say replace now if not sooner.

I would suggest that the best tires are the most satisfactory. I found cheap tires like Goodyear are not round and are hard, or impossible to balance. A lot of companies make truck tires that will fit your wheel, but, as far as I know, only Goodyear and Michelin make soft riding RV tires. That makes Michelin the only choice for me even if they do cost more to purchase.

I beg to differ.

1. Goodyear tires are not cheap. They are considered tier 1 tires.
2. Goodyear tires ARE round. (at least mine are)
3. If Goodyear makes soft riding RV tires, how can they be hard?
4. There are many other choices besides Michelin and Goodyear. For example, Toyo, Bridgestone, Hankook, and Continental.

I just put Bridgestone R 250 tires on our coach along with Koni shocks all around. Very happy with them. Even DW stated she felt as if we were driving a different coach. As said,there are many good brands to choose for RV tires.
