tires

Checking the ol moho over for a big spring trip and the tires just didn't look right. Made a trip down to my tire guy and he says these tires are 5 years old and they are real iffy for even a short trip. The tires are oem Michelins with 35k miles. They are cracked bad up next to the rim so I have 6 new ones on the way but not Michelins. Is this the norm for these tires? I have dealt with this father and son as my father for well over 50 years so don't go there. Just want to know is this what other people are experiencing.

    Date codes are same way on all road tires since 2000. Check the other side of tire for the last four digits. Usually only on one side.


    Ah ..... Not exactly.

    Since 2008, the TIN (Tire Identification Number, aka DOT Number) is required on both sides of any road tire, except for the date code portion, which only needs to be on the side intended out.

    But the format of the TIN dates back (pun intended!) to about 1970 - and it was only required on one side and typically that side was the side intended inboard.

    I recently bought a 2002 Monaco with Toyo truck tires (22.5 inch rims) The date codes are different and i could not decipher the mfg date. Any help out there?

Sounded like BS to me, but he was correct and that's what happened to my OEM tires.

    Really....? Now that's an additive! I sorry but, I have had very bad luck with Michelin tires. The latest were in DWs Lincoln MKZ. Less than 24,000 miles on them and had very sever sidewall cracking. These tires were less than 4 years old. If you are having good luck with Michelins, great, but my experience with them has been dismal. I learn from history, and try not to repeat it. Had almost 12 years on the original Goodyear's on the MH. Not saying never, but will avoid Michelins at all costs.

    On March 19th this year I had my 6 10 year old Bridgestones tires replaced with new Bridgestones at a cost of $3,166.

    The sidewalls were like new but there were some minuscule cracks in the depth between the tread.

    Insofar as the tires on a coach are the weakest link between it and the pavement I will spend the extra $$$$ on quality tires.

    Best of luck to all and safe travels.....:)

    We also replaced our Michelins, less than 5 years old and very low mileage. Sun damage was the culprit.


    I keep my tires covered when parked for more then a week. No sun no damage.


    You live in Florida - so that makes sense.
    We live in Ontario so the sun is not as strong but probably still a factor. We have never covered our tires and have never had a problem on our other RV's. The tires are sprayed regularly with a UV protector but I hear there is good and bad with that stuff.
