When to replace old class C tires?

Pretty sure that the going recommendation from the manufactures is 7 years.

I know that Discount Tire will hassle you (might not be willing to rotate/repair/mount balance) at 5 years.

My sister had 3 tread separations this year on tires that were 3 years old. Seems ridiculous to change that soon, but after you spend time changing tires on the side of an interstate with semis rolling by at 80 MPH right next to you, you might change your mind.

I'd replace them whenever 1) the tread gets too thin, or 2) the sidewalls begin to show cracking ... whichever occurs first.

For what it's worth ... my lightly driven 20 year old pickup truck regularly gets 10-12 years on it's tires before either thing happens and it sits outside in the sun. However, so far our Class C can't seem to get past 4-5 years before it's tire sidewalls crack. :h

OP here...Ya, pretty good article in a way. There answer when to "re-tire" IMO was round about..."While most tires will need replacement before they achieve 10 years, if the motorhome is not stored in a covered location"

Six years from the date of manufacture, not when they where replaced, some tires at some tire dealers have been stored for years.

The manufacturing date is found on the side wall two numbers all by themself, the first 2 numbers are the week and the last are the year.

0814 as an example indicates the eighth week of the year and the fourteen is 2014, I replaced all 7 tires on mine and they were looking like brand new but they were 6 1/2years from manufacturing, be safe on the road, do not gamble with your life and loved onrs, or totally inocent persons trying to save money, it is not woth it.

Have them inspected.

I'd lean towards at least replacing the front tires.
