Tires

RV tires AGE out vs wearing out cause of limited yearly mileage

Rule of thumb is 5-7 yrs for trailer tires and 7-10 yrs for MH tires.

Having tires 'professionally inspected' is always a good idea.

For me.....
I am anal about tires.
At 5 yrs (5th wheel) I replace.
I would rather get them at my leisure when most convenient then when on a trip needing tires, possible damage to rig .....hassle/added expense etc.

If I had a MH would probably increase time frame to 7 yrs vs 5 yrs for trailers due to lack of 'tire scrubbing' incurred on trailer tires when maneuvering


As suggested.......check out DOT tire date.
Those tires could be 7 yrs old now

How to determine when to replace tires????

We have a 2011 Pheaton with less than 20,000 miles. Unit stored inside when not on the road. original tires look good with adequate treads.

Recently, it was suggested I should consider replacing because of age...

Thoughts???

You're getting there, however with excellent care, some go 10yrs.
We blew a 5 yr old GY, but didn't own the coach, except for a few months prior and most sure they had the very worst of care.
Jacks not down when parked, no tire covers and who knows is they were ever run with low pressure.

Yes, without knowing the age of the tires, or how they were cared for, not sure our opinions are relevant for you, your pocket book and your safety.

I would not get concerned until the tires (not your coach) are around 7 years old. Even then, if there is no noticeable checking or cracking I would likely still keep driving. I have had 10 year old Michelins on my coach and they were fine. I also just replaced 6 year old Michelins as they were cracking badly. Common sense goes a long way here.

Have you put the majority of the miles on them?
Have you weighed and adjusted the air pressure accordingly?
Have you ever traveled 25+ miles with a soft tire at speed?
Does it sit more than it moves?

My answers are Y, Y, N, and N so I went 7 years on the front tires and 10 on the rear. Those 13 year old tires are on the rear of my 10 wheel dump truck and they still are in good shape.

I would replace the front tires sooner than the rear.

Stormy Eyes has the first important question. How old are the tires by the date codes?

6 years old as far as the coach possibly, but if kept out of the elements and moved around regularly you may be good for a bit longer.

My DP sits outside but I keep the tires covered and it is used year around here in Florida. But I don't want to risk a blowout and a bad accident either. I will more than likely change mine out around 7 years.

At five years, you should have the tires inspected annually by a tire professional. Many tire manufacturers recommend replacement between seven and ten years, regardless of how the tires look. The interior structures of the tires will still age no matter what kind of environment they were in.

What is the DOT date code on the tires? We know the coach s a 2011, but that does not tell us the chassis manufacture date or how "fresh" the tires were when built.

I'm going against the grain here....

For me, I absolutely would run a coach on those tires. My total opinion is if they have been away from the elements they have aged way less. Especially good if you haven't kept the coach in 1 spot for months at a time.
