Tire help

Hey all!

Was puttering around the MH yesterday starting to get it ready for the season (I'm eager, can you tell? LOL), and noticed the following cracks on one of the front tires.

I know cracks can be benign, or a sign of something far more serious, depending on what they look like - but I don't know which these are.

Half of the tires are Michelin XZA 8R 19.5, the others are Michelin X 8R 19.5. They're on a 32' 1986 Triple E Invitation Class A motorhome, with a little over 100,000kms on it.

Do I need to replace that tire, and if so, what should I replace them with that will give me a smoother ride and better handling without feeling like minor steering adjustments are causing it to swerve everywhere? Right now it feels like I'm driving on skinny little bicycle tires.

Concur with the others in that you need to replace ALL of the tires ASAP. I run Sumitomo 8R 19.5 tires on my coach and they are fine. Your local tire shops may not stock the tires but they can get almost any brand and size. If your coach has a spare, also replace it as most likely it is as old or older than the ones on the ground. Don't run on old tires and blow one like I did!

You could go to the nearest Kal Tire or Fountain Tire. They deal truck tires but also a good source for RV tires. They are knowledgeable and can answer all your questions. I used to live in Central Alberta as well.

Amazon sells tires. If you're a prime member, that means they'll ship them free. Takes 5 days for tires. If you have a shop near you that has the equipment to change them out, ask if you can have the tires shipped directly to them. I've used Love's Tire Stores for that over in Oregon.

Your tires are probably both. 🙂

HANKOOK tires are a good choice..


gbopp... that I have, yup! I'm not maligning the Michelin tires, I was just surprised to see cracks that weren't there when I tucked the old lady into bed in October, and wasn't sure if they indicated a structural failure in the tire itself, or if they were cosmetic and safe to drive on.

Does Hankook make the 8R's?

Not sure where you are located. Here in Northwest many truckers and RVs run them.
Don't let your local tire dealers say that 8R-19.5 are not available. I run the 8Rs in the rear and wider 245s in the front.


We're in the middle of farm country Alberta - the closest RV places are 1.5 hours of highway driving from where we live. 😞

Can I run 245's on the same rim the 8R's were on, or would I need new rims as well?

From what I understand of how to read date codes, it's the last 3-4 digits on the DOT line, right? In which case, they were made in the 32nd week of 2003... and it's high time to replace them cracks or not I guess!

I've seen the multitudes of tire threads out there... it all kind of mumbo-jumbos after a while. Was hoping someone could cut through the jungle and give me a clearer answer - the all the tire shops around me deal with farm trucks, and haven't got the foggiest idea about RV tires.

Not what anyone wants to hear but You should replace those tires. What is age of the Tires? Date code information on the side wall of tires. I would not think they are original being 100,000 Km as your stated mileage. Also there are numerous posts on this site as to when tires should be replaced and which brand to buy. From tour pictures I would say replace Don't risk your and others safety. Welcome to the Forum

Hey Bud!

That's kind of what I thought. Those are the unsafe kind of cracks then, yeah? 😉

Any suggestions on what to go with?
