Hey gang,Regarding big, DP tires...I know most adhere to this rule and some prefer to replace tires within 7 years or so of date code. Others replace the steers every 5 and the drives every 10. Others still will have them all removed and the interiors inspected before giving up on them. Etc, etc...I'm inclined to err on the side of caution, myself, but I'm curious to hear your thoughts. And to see if anything has changed in the last 5 years since this thread.So given...6 - Toyo M-154 265/75R22.5 tires with 10,000 milesInstalled March of '13, but approaching 10 years of date codeBabied and covered most of their lives, in beautiful (where visible) condition with no checksEntire lives in Santa Cruz with a very mild climate. Last couple of years undriven and parked without the jacks down and uncovered with driver's side facing south (the sun... and Central California coastal fog) On a Freightliner/Cat chassis running fairly close to GVWR / tire maxReplacement cost - $3,100What would you do?EDIT: Here's a good read posted by dougrainer 5 years ago. The study indicates 6 years is the maximum for safety. Though it appears to be general tire specific. No mention of commercial, one way or the other.http://www.ntsb.gov/news/events/Documents/2014_Tire_Safety_SYM_Panel_4b_Kane.pdfAlso... some seem to indicate that commercial truck tires are more robust than RV tires, despite the size. I can say this... the Toyos are spec-ed at 99 lbs vs 90 for the OEM Michelins. All that said... they also undergo more severe punishment..

I would replace them. $3100 sounds like a lot, but when you figure out how much reparing all the damage done by an old tire blowing, it's cheap.

I'm told that in some states tires over 8 years are considered hazardous. (NOTE I have made no effort to verify that. I replaced the tires shortly after being told that for other reasons. (They needed it) but that is what I was told. I've seen both 5 and 7 as the recommended replacent intervialJust now the motor home is in a bone yard (Long story. but not unhappy)And the car the insurance check paid for in full.. Tires are like 7 MONTHS old.

I wouldn't take the chances - replace them. I've seen tires that look brand new but are aged out go. That $3100 will give you another ~7 years of service so consider it a $37/mo insurance policy.

I replaced my DP tires a month or so ago--2 fronts were 6 years old and 4 rears were 7 years old--with Hankooks. $2500 out the door, BUT, I sold my take offs to a contractor for his low boy for $700 right at the tire store so it ended up costing me $1800 out of pocket for peace of mind.

Wow!

I feel like that rig has been in your signature the entire time you've been a member here, no?

When did this happen?

Buy proper truck tires and stay away from the RV ones they will last a lot more than 7 yrs. Just my thought's.

If they had not sat for 2 years…had been used regularly I probably would have gone a couple more years on the rear, but not after sitting that long at that age. Went 10 years on the rear (7 on the fronts) on previous DP and I then put them on the back of my 10 wheel dump truck.

Just ordered 6 new tires for the rear…replaced the front 5 year old cracking Michelin’s when I bought the rig 3 years ago. Cracks on rear are getting big enough so replacing at 8 years.

My rig is just a smallish {24'} Class C but the blowout of a 5+ year old Michelin the day after being inspected and aired up for the load by Discount Tire did $4,181 in damage blowing the wheel well right up through the coach. Had it been a front wheel it could have easily killed us. I'll never own a tire older than 5 years again.

My dear departed dad used to tell me "Son, any problem that can be solved by money is NOT a problem... If you have the money."

Just saying. Good luck.

Desert Captain,
Did your insurance cover a large percentage of that damage?
