I know that most folks tend to replace tires by age, but if age was not an issue, what would expected tire tread life be? I am at almost 90K on my 4year old Goodyears 275x70x22.5 rear tires and they still have decent tread. I replaced the fronts with Michelins at 20k due to severe rivering, and I can't wait to get rid of the rears, but I am also not looking to throw $$$ away. I will replace them when they wear out. As a side note, the Michelins have been totally trouble free for 70k miles, and there have been no changes to suspension or alignment, only change was steer tires.

Commercial type tires will last longer.Most RV'ers end up replacing due to age because they don't put on a lot of miles each year. A typical RV'er travels about 150 miles to their destination.

Cbones, if it were me and you have plenty of tread, I would go up to the seven year mark and maybe change them all. If you want to keep the steers, put that set on one dually side and keep a fresh set on the front.Our seven year old Michelins had 57,000 miles and had plenty of tread. The tire shop gave me $50 each for the take-off's as they will resell them to re-treader, a guy needing a tire or two or to a guy who needs tires for his farm trailer. They still have life in them some way or another.Safe travels,MM.

At the rate I am going I would expect 120-140K which I think is pretty respectable.

Keeping your tires covered from the sun will certainly extend their life. However, tread wear is not the only indicator of when to replace. If the sides are getting cracked from the sun/ozone attack, then safety should rule. If you check on the specs of new tires, they usually define tread mileage estimates based on number of plies and rubber compounds.

We travel quite a bit so every three to four years I get new tires. My old ones have usually 50,000 or so miles on them and I have always been able to negotiate a trade-in value for them. Obviously this lowers my over all tire cost and I prefer the ride that I get on fresh tires.

The Firestone tires (12R 22.5) on my coach lasted 80,000 miles and I was very pleased with that. You say yours are only 4 years old and have 90,000 miles miles on them. That's even better. If you still have what is considered a safe amount of tread (Lincon's head is fully visible when inserting a penny into the tread) there is no reason to replace your tires.

Keep running the tires but keep watch on the wear. I would not recommend wearing them down to less than 5 to 7/32 inches of tread remaining. In my fleet experience, I have seen the most failures when attempting to run off that last 3 to 5/32 of rubber. Remember, 2/32 is the minimum tread depth you can legally run.

If you are replaceing RV tires due to tread life.. have your alignment checked, Weight the rig, and adjust tire inflation to match the weight (4 corner weights not total weight).

Either inflation or alignment is 'off' if you are wearing out tread. (or bad tire can do it as well).

Cbones, that is really strange about your Goodyear Tires wearing like that and you change brands do nothing else and the problem doesn't show up in the new tires? I would get the rear tires inspected once a year and run them out! My guess would be 7 to 10 years!

Some states are at 4/32 now!!!
