I recently bought the 2004 KS with original Michelin tires, and drove it 800 miles home. The tires rode nice, but with tire manufacturer dates exactly 12 years ago, I didn't want to take the risk and bought new tires very first thing. I actually thought long and hard before I drove home on them, thinking about buying the tires before I drove home. Prior owner had taken good care of the tires, always garaged or covered, regularly treated with Aerospace 300, but the risk wasn't worth it to me.

Why would I call CC? As I stated, it came from the factory that way plus those are the tire sizes shown on the weight sticker on the rig.

When replacing tires in Dual position you MUST be sure the tires have a measured Outside Circumference variation of no more than 3/4" difference between the pair.

Here is a post on matching duals.

You can read THIS post and THIS one for more details on how to measure.

Mismatching duals with bias tires MAY be less important (don't use this statement to imply it is OK)

Radials are more critical. Check out my posts.

If ya look after your rubber, keep then clean and properly inflated, 10 years shouldn't be a problem

I'm curious. What was the defect? Were the tires part of a recall by GY?

I haven't seen posts that include the measured tire loading (including side to side variation)
Once we know the facts on load then the reason for tire size selection may become obvious.

The tires on our 2005 Pace Arrow we bought a year ago are the originals dated 1704.... They have 44k miles on them and are just showing some cracking... we might replace them this year but havent decided.

My Continentals are only 4 years old but after seeing the damage done by a catastrophic blowout on a 4.5 year old michelin last week I am seriously thinking about new tires. The Country Coach is owned by a friend who is a long time coach owner who is meticulous about his maintenance and has the money to do it right. Even with a TPMS he had no warning when it blew, shot him from right lane to the median of I-85 and he barely got back across to the shoulder. The damage included broken and buckled floor tiles, destroyed generator slide and muffler, buckled fiberglass, damaged wheel and several other things. The incident scared the wife so bad she made the rest of the trip driving the toad.

My 2000 Suncruiser got its shoes replaced last year. It had original ones date code 99 with 13000 miles and sat outside for 4 years before I bought it in 12. No cracks and great tread. This Forum convinced me to change them last year. New XRVS and boy the ride difference was almost worth the 3000.

I just replaced a 10 year old set of Goodyear 295 75 22.5 with Firestone 1100 22.5.
They do ride alot smoother and quieter.Maybe because they are new or maybe because they are different.
They truck tire shop I deal with sent my old tires to the retread shop for inspection. I came back from our winter trip and found they gave me $70.00 a tire for casings.

My tire story

I just bought my first Class A RV, a 2004 Holiday Rambler Imperial. It has five Goodyear G670 tires dated 2007 with one 2008 on the front passenger side. I followed the "How old are your tires?" thread with interest because I was looking for guidance on when to replace the tires. I took delivery of the RV this past Thursday and spent until this morning (Saturday) cleaning it and moving stuff from my travel trailer into the RV. We decided to drive it to the truck stop to top off the diesel because the fuel gauge was reading low and I wanted to see what it would read with a full tank. The distance to the station is about 10 miles one way and we drove down I-95 at 65mph most of the way there. On the return trip we were about a mile from the storage yard on a city street doing about 35-40 mph when the driver front tire violently blew out-pic attached. We spent about 2hrs in the center turn lane waiting for a tow truck to arrive and finally made it back to the storage yard. I had intended to have the front tires replaced next week and replace the rears sometime later on but after today's experience I'm getting all six replaced. Thank God we were not on the highway when this happened. I will probably buy either Michelin or Toyo tires based on what I've read about the Goodyear RV tires and from today's invaluable lesson.

Hope this helps you decide when to replace your tires. Be careful out there!
