Hey all. On another RV forum someone posted they seem to think that the 16inch or 16.5 inch tire was over worked (on older couches) and that the newer units that use 19 and larger tires have fewer tire problems. (and now for my question)

I realize that the poster may have been talking about larger (heavier) rv's but what is the general feeling of tire life with the gmc's?

and in case you can not tell I don't own one yet but am working on it. I do have a 1974 Dodge class c for sale.

This is a well worn subject here -- however, we may have a consensus that you should go to 16 inch vs the 16.5 OEM. Age is more often our issue than wear -- so many now prefer to use for no more than six years from date of manufacture on the tire.

I sent an email to BF Goodrich regarding tire life. They replied that any of their tires should last 10 years, if given good maintenance. I run BFG TA 245-16-75R. Obviously, too much ozone, too little air, etc. can be a big factor. My coach is garaged when not on the road (on wood) and the tires look fine with no cracks or other discernible problems. They are 6+ years old. Their email also said that, on general principles, tires should be retired at about 10 years.

Michelin has the same recommendation.

Some people believe that the warranty period is the expected life of the tire. They choose to perpetuate that they are unsafe beyond the warranty period rather than use the published life cycle as recommended for RV use by the manufacturers.

When I ask why they are driving a GMC that is past it's warranty period I get no responses.

It is only money.

George,
It would be nice to get a letter from BFG stating that, along with
some recommendations for storage for long periods of use. Maybe we
need to rethink our philosophy on tires here.

My theory is that the sun exposure is 98% of this. I garage my coach and cover the tires even when out camping. Never had any tire issues. The Michelins I had, I ran for 13 years and then sold them to a guy that used them on his truck. I have seen them on GMCs parked on the beach with strong sunlight start cracking in just 3 years.

A friend of ours just bought a new pull type camper. He told me that the tires were filled with Nitrogen to help them run cooler. I think he said it added $40 or so to the price. Is that a factor worth adding to the tire lifetime equation/discussion?
Just a thought,

Since air is already 78% nitrogen I really don't think 100% nitrogen will make them run any cooler. i suspect that is marketing hype.

Usually people use 100% nitrogen so that they don't have any O2 inside the tires with the theory that no O2 will stop the tires from oxidizing as quickly. However with the outside of the tires surrounded by O2 in the air that doesn't make a whole lot of sense to me either.

I sure wouldn't pay an extra $40.

Hi Steve, I asked that question, plus inflation info, and they would only answer the above. I also use nitrogen from Costco.

Ken B: I don't know if I understand your question re warranty; I run them as long as I can because of $$, taking into account the problems w/blowouts.
