Michelin says.

During the pre-trip inspection, be sure to check your tires for signs of aging, weather checking and/or ozone cracking — these show up as tiny cracks in the rubber surface on the sidewall of the tire.

If the cracks are less than 1/32" deep, the tire is fine to run.
Between 1/32" and 2/32", the tire is suspect and should be examined by your Michelin dealer. If the cracks are any deeper than 2/32", the tire should be replaced immediately.

Hi breed,
Go to Michelin Sidewall Cracking Chart - iRV2.com RV Photo Gallery for the Michelin tire chart. Consider printing and comparing the chart to your tires.

You haven't said how old the tires are, according to the date code. We know they already have visible cracks. Tread remaining is a meaningless indicator at this point.

Hi breed,
There will be a 4 digit code on the side of the tire. The first two numbers are the week of manufacture. The 3rd & 4th digits are the year of manufacture. An example is a code of 1404. The tire was made the 14th week of 2004. The code will be by itself and not associated with any other number.

The 4 digit code will have "DOT" in front of it.

A lot of members will agree this may be the biggest factor and if over 7 years you should probably replace ASAP.

Do all the tires appear to be in this condition? May want to move the best ones to the steer tires or consider replacing them sooner. May not be such a big hit to the wallet to just get two done for starters.

As one who has been in this position I can tell you it is better to do it sooner than later. It's not much if a holiday to be sitting in the side of the hiway waiting for a service truck.

My next question would be do you have a spare? And do you have RV roadside assistance insurance. Would highly recommend that you do as this has pulled my bacon out of the fire on a couple occasions.

Also just so you know, getting a flat on an RV isn't just losing the tire. There is a very very high probability of damaging the wheel well and other cosmetic, mechanical and electrical.

All in all just plain not fun thing to experience and may end up costing you a lot more in the long run.

Just my opinion based in my limited experience

We had slight cracking on ours as well, tires were 7yrs old but only had 25,000 miles on them, went on a camping trip about 200 miles from home and while doing an inspection on the tires a couple days before leaving the campsite we had a bubble show up on the side of the right front tire. I told DH I would not drive home on that. I did not want blowout & damage done to RV, we called Les Schwab, 20 minutes away from the campground, they ordered tires for us and we had them installed on our way home. Also if you are a member of FMAC they have a program for purchasing Michelin tires at a discount--check that out too on their web site. I didn't know about that when we purchased ours last year.

Take a look at http://www.barrystiretech.com/dotcoding.html. I would bet your tires where manufactured the 8th week of 1996, using the old three digit date system.

As Mike said those tires are 17 years old! Don't drive another mile; well OK drive very slowly to the nearest tire shop.

I've gone down the road on 10yr old tire in mint condition (always covered, not a single crack), but that was with a smaller class C, and that was still probably pushing the limits. If you have cracks, and your tires are 15+yrs old, I wouldn't even take it out on the highway. If your pocketbook won't allow for new tires yet, try craigslist or tireshops for used ones. Tire shops usually turf 7yr old tires, so you can usually get them free or cheap.....something to just get you down the road until new tire day comes.
