If sunlight does all the damage, then the inner tires of the rear axle, which never see sunshine, should last almost forever. Yet, when we change tires, we change the inner dual tires as well. Why is that???

Sunlight causes cracking but the deterioration comes also from ozone and from standing around not being used. You should also have similar rolling circumferences on both tires otherwise one will heat up more than the other.
Personally, and this really is just my opinion, it's the lack of use that causes more damage than sun and ozone. Use that as a reason to get the MH out more often!

Tread wear, and ride height. Robbie Plus, I posted a piece about ozone effecting the longevity of tire life.

Bridgestone's U.S. Unit Advises Tire Life-Span Limit on LT tires.
Service Life is Not Determined by Chronological Age
50pascals your post does drive home the false info about tire life that gets posted on this forum. The info below just applies to car and light truck tires. Those who have done any trucking knows you judge a heavy truck tire by its external condition and not the date stamped date or the date the tire was put into service.
I remember when I walked across the street from the office where I buy all of my tires and asked him about the 6 year info posted on this forum. He looked at me like I was an idiot and said if they look good on the outside then they should look even better on the inside.
Having hauled heavy loads on 20-25 year old tires without issues on farm trucks I quickly said well it thought that was the case but you know how most of the stuff posted on the internet is by those who are clueless and I guess the 6 year replacement myth is just is a good example of that fact.
Serious some RV's tires would be unsafe if changed every 6 months.
I think this is especially true in the TT/5W class of RV and can even be the case with a 22.5 inch tire on the front of some MH's due to the load or the placard PSI being stated too low.
All sources state a tire that has been ran overloaded or seriously under inflated for any time should be replaced at once period.
As I stated before if you are loosing sleep over your tires go by more tires. The HUGE concern however are you getting tires less likely to blow out or not than the ones you are pulling for someone else to install?
Personally I think running with some margin (not maxed out load wise) is about all on can do in truck tires. Yes brands can make a difference but they all have duds.
What ever you do make sure not to repeat what you read on this forum in front of a tire professional if you do not want to get the "what an idiot" look.

So unless one has the life story of a tire , one may be replacing them very prematurely by following the date code .

This post is the extreme case of "apples and oranges" Race tires have nothing in common with street tires, especially truck tires. You cant compare some special exotic race tire compound/construction that are stored in a climite controled enviroment to tires "in use" exposed to the elements and road hazards that sit for long time with the heavy weight of an RV on them. RVs are different animals and the loads and stresses put upon their tires are not common to other types of vehicles...

I don't care what they do, or don't do, or can do. I want fresh tires on my rig and my last year's GY replacements are dated 2007, so there won't be any controversy over it.
I'm still of the opinion that most tires just don't blow unless caused by a road hazard or low air pressure, regardless of the brand including the Chinese line. I like top brand names, though...especially Bridgestone....but mainly for no hassel replacements, especially when traveling out there somewhere.

I tend to agree w/ you. It seems that when Firestone had that debacle about their tires on SUVs blowing out, it was found that "high speed, and heat" were the main culprits. I'm not sure anything about age was included. Robbie

The real problem was actually under inflation. Ford used a low figure for air pressure recommendation so as to improve the ride and Firestone went along with it. Many of the tire failures were on heavily loaded units where the lower pressure caused a heat buildup and tire failure.
