At the risk of hearing flames from the extremes, how long should I really expect TT tires to last?My situation: I have a 2005 Jayco Eagle 298BHS (8000-9000lb loaded) with Maxxis M8008 ST225/75R15 load range D tires. The tires look great, no observable sidewall checking/cracking and lots of tread as they only have 15K-20K miles on them.Since I'm planning on getting a 5er at some point, spending $500+ on tires would be lost $ if I make that move and it wasn't really needed. With that said, not sure if I'll make that move in next year or not.Looking to hear from a good cross-section, not just the ultra conservatives, but where on the true tire life distribution am I? Already at the 1% outlier point where 99% chance I should have had a blow-out already; pushing my luck past 1-sigma where ~80% would have seen a blow-out at this point; at the nominal point for half to experience problems; etc?I'm not looking for insults or judgment, just honest open feedback.Thanks,Ron

What? No insults or judgements? You are in the wrong place, especially with a 'tire' discussion...:)My take, and I have load range E Maxxis: 8 year old tires. How have they been stored and where? (southern or southwest climates in the sun??)I think you are on the edge. I probably would not go another full season on them. Remember, new tires can also be a selling point to prospective buyers.

According to the National Highway Traffic Safety Administration, recommended service intervals are 6 to 10 years based upon the manufacturers recommendation. Visible inspections will not tell you how the internal structures of the tire are wearing. My own personal opinion which should be taken with a grain of salt is that I'd replace them after 5 years in very hot climates, and 6-7 years in cooler climates.Check out this government website:NHTSA Recommendations

I'd run the old tires. Let us know how long they last.

Per Maxxis tire warranty;"Subject to the limitations contained in this Limited Warranty, your new Maxxis tires are warranted under this Limited Warranty against failures due to defective materials and workmanship for a period of five years from the date of manufacture." Your living on barrowed time if those tires are from '05. The tire may look great on the outside but dry rot internally.

Inspection off the trailer is far better point of view in my experience.

Sorry to extend this thread, but MUST say THANKS again.

I pulled all wheels off tonight to take in for the new Maxxis E's (two dealers told me the wheels I have would be fine going to E from D (only an 80psi vs 65psi thing as trailer still weights same 8-9K)).

Good news is that the spare looked perfect even though it was 10 years old. Lucky news was that all 4 running tires had several 1/2"- 3/4" cracks between treads on each, with one tire having a several inches long crack running between treads (all cracks ran along tread on top surface with one tire also having several small cracks near the tread on the side-walls).

I take back my previous comment about probably being OK. I count myself fortunate and don't planning on running 9yrs again.

If the tread is flat across, round in circumfrence, and no bad wear pattern I would keep running them.
I have had 2 sets (not Maxxis) and both had tell tale signs of going bad before they let go at about 3.5 years. Just bought some Maxxis and expect 6 to 10 years as I would with any tire.

Rule of thumb for the group i camp with is 5 yrs, i had valve stems crack after 4 yrs, tires started showing dryrott at 5yrs, so i replaced them, and they do not sit in the sun, tt is kept under roof and tires parked on wooden blocks 90% of the time.

Thanks all for the feedback.

I've just scheduled to replace all 5 (spare was >10yr old) with Maxxis load range E. Tires Plus didn't have D's available, and believe it or not the Maxxis E's were cheaper than I found Carlisles for.

Net-net I've kept the Maxxis but upgraded to E's as well as upgrading 9+ years (insisted on 2013 date codes). Wasn't too worried about my current tires for short runs, now I won't be worried at all and can start longer trips with this trailer when I retire next year.

As always, thanks for the feedback.

Are your wheels rated to handle Load Range E's. If not, you might want to reconsider finding D's or upgrading wheels.

How do you find out if your wheels are rated for E rated tires?

9-12,000 miles on ST tires is what I have read. Tread is a non-issue.
That would mean some people would go through 2 sets of tires in one year, if those STs didn't blow up first...I don't think I would follow that rule.

The Maxxis tires on my trailer were born in 2005. I bought the trailer new in 2006 and used it for seven years.

When I got home from my 2013 summer trip to Key West, two of the tires had signs of tread separation although everything else looked new. Fortunately, they didn't leave me on the side of the road and died a peaceful death in storage.

I now have a new set of Maxxis and am ready for another seven years or so.

:) Hi, it's hard to put a date or mileage on tires. Most people don't even think about it on cars and trucks. Most cars and trucks can actually wear out their tires. Trailers usually don't wear out their tires. My trailer is also a 2005 model. I replaced two of my tires at about 3 years because I noticed a small sidewall bubble on each one. I replaced the other two at about 7 years due to the beginning of tread separation. I don't keep track of my trailer's mileage, but each trip is usually 1,000 miles or more. And one trip was over 10,000 miles. Keep them at max cold pressure, don't over load them, and don't tow too fast. Visually inspect your tires at all rest stops, gas stops, and camp grounds. (this works for me)
