Hi-

I have a 22 ft 2001 Dutchmen Express with 58K miles on it. We purchased it in 2004, with about 47K miles on it.

I know everyone says replace your tires every 4-5 years, I agree. But I am wondering, with the mileage that was already on it, if the tires hadn't been replaced once already. The people who had it kept it immaculate.

I thought I read somewhere back that there was a place on the tire itself that had the year it was made-or I could be crazy. Is there any such way to determine the age of your tires? (I know, I know, tread isn't an indicator)

Thanks!
Lisa

look for the DOT label, besid the will be a 4 digit code. The first 2 numbers are the month and the last 2 numbers are the year. They should be in an oval shaped circle

It is a good bet they have not been replaced yet.

Firestone stamps manufacture dates on tires (example is lets say right now we were in week 45 so you will see the number 4505). Ford has begun urging consumers to replace tires six years after their date of manufacture, regardless of wear. Toyota has long warned drivers that tires are perishable.
Daimler–Chrysler's Mercedes division had been telling drivers that tires last only six years; last fall the Chrysler group began including such a warning in its 2005 owner's manuals.
General Motors so far has not taken a position.
The information needed to determine the age of your tires is present on the tires — but it may difficult to determine. Look in the oval stamped in the tire sidewall. I went out and checked my car and learned that all four tires were made in 2002. Then I checked the spare: it read 1401. That means it was made in the 14th week of 2001. That's 4 years ago — not quite at its expiration date. Slate

Its the law now that tires must have this info. Check before you buy, because some tire shops sell expired or close to expire tires at deep discounts. The same with Batteries! Slate

Be aware that the DOT code is often only on one side of the tire and may be mounted so it is on the inside (and a pain to read).

Some good info at http://www.nhtsa.dot.gov/cars/rules/TireSafety/ridesonit/brochure.html

See the Michelin RV Tire Guide. Great stuff in there - including how to read the tire info off the tire, with pictures and everything!

http://www.michelinrvtires.com/michelinrvtires/pdf/RvTireGuide.Pdf

Note that Michelin advocates replacing tire by inspection, not age - though they do say to replace them at ten years even if inspection would not dictate that replacement.

"While most tires will need replacement
before they achieve 10 years, it is
recommended that any tires in service
10 years or more from the date of
manufacture, including spare tires, be
replaced with new tires as a simple
precaution even if such tires appear
serviceable and even if they have not
reached the legal wear limit."

[345] = the 34th week of 1995. They are overdue for replacement.

In 2000, they went to a four-digit code, the first two digits are teh week of manufacture and teh second two are the year.
