Thanks for the informative blog post. What were the readings on your trailer TPMS before the blowout?

We had two set of Maxxis load range E's (10 ply) on our 2005 Safari 25FB. We bought the first set after our OEM Marathons gave up the ghost. The first set of Maxxis lasted about 20,000 miles before the had tread separation. I considered that pretty good, so I bought second set. This set only lasted about 8,000 miles before the same type of tread separation started. This is when I got totally fed up with crappy ST tires, and went with the 16" Michelin LT's. If I had gone to the Michelins when the 2005 Safari was brand new, I would have been ahead by about $1,500.

Just upgraded the 15" wheels on our 19' Intl to 16" last week based on collective advice from the veterans on these forums. Stock GYM lasted less than two years and maybe 8k miles before steel cords were showing through the rubber on both sides. Just drove from Las Vegas to the Redwoods (about 850 miles) over the past two days on the new Michelin LTX's. Crossed a half dozen legit mountain passes, drove at 70mph through the Mojave Desert in 100+ degrees, on tight narrow roads through the Sierras. No issues whatsoever! This is just one person's experience so take it for what it's worth.

$1500 for new tires and wheels minus $500 from selling the originals. $1,000 upgrade on four new wheels/tires, kept the original spare.

Why did you choose Sendel wheels over other brands of aluminum wheel? I'm going to switch over from 15" Maxxis to 16" Michelins this winter, but many Airforum folks have chosen to put their new Michelins on Sendel, and if they are better than other aluminum rims I might do that too.

Several years ago I put four new Maxxis on my 29' Excella together with tire monitors; E rated and had them at 80 psi. and after 2.5 years had two tread separations that were alerted by the tire pressure monitor just as the tires started to come apart on opposite sides. Replaced with four more Maxxis but now realize that Maxxis are also speed limited. I prefer 65-70 mph on interstate highways, but don't want to worry about over speed with my tires. Without the tire monitors I would have spent thousands on repairs to the AS.

I try to get as much learning as I can on others' tuition; and I had heard enough horror stories about the 15" Goodyear ST tires to know I wanted to upgrade. My 27FB Classic has a GVW of 9,000 lbs, so I could not get a 15" LT tire to take that weight within a comfortable margin. So, I went with the 16" rims and Michelin XPS Rib tires - just for good measure. Just came back from a 3500 mile trip and very pleased with the ride, performance and peace of mind. Look at your numbers, weights, capabilities - and budget. Always get the best you can within your means and you can't go wrong - enjoy!

A tire upgrade is always money well spent in my book.

We do not have TPMS on our tires.

Excuse my ignorance, but I suspect not just any Sendel 16" wheels will do? What should I look for, or should I just ask the Michelin tire place? I spotted some wheels that I like, which say "16X6 8X6.50(165.1) +0 4.90". What do those numbers mean (other than 16" with 6 lugs). Thanks for any insight. Oh, and I will be replacing the lug nuts with better ones, and a torque wrench to tighten them.

I have had my Maxxis tires on my CCD 28 International now for 4 years and about 30,000 miles. Run 65 PSI and 60 to 65 mph in them. Have tire pressure monitors as well. For the cost of putting 16 inch rims on and tires accordingly, and with the need for tire pressure monitors on either option, you can buy a lot of Maxxis tires. However if you want to run 75 mph go with the Michelin tires and rims, please get them: I don't want you around me traveling like that without the very best hardware. I'm never in that kind of hurry to risk life and limb on any tires on a trailer.

Here is what we got for 16" wheels

Ditto: Maxxis E-rated tires on 27FB. Alta & I just returned several weeks ago from the Lewisburg, WV rally (9,000 miles/6 weeks), where I attended a seminar by a long-time Airstream service man. His recommendations:

1. Whatever: get rid of the Goodyear Marathons.
2. For typical driving (ie, up to 65 mph): replace Marathons with E-rated Maxxis.
3. For more extreme driving: replace Marathons with Michelins, which requires replacing 15 inch rims with 16 inch rims.

I bought the 4 Maxxis tires over the Internet for approx $450 including shipping & sold the 4 Marathons over the Internet for $300, for net out of pocket $150. I paid my local tire dealer $75 to change over the tires, balance them, & add metal tire stems, for a total out of pocket $225.

The Michelins with 16 inch rims would have cost me approx $1,500. With the "savings" of approx $1,300, I bought a tire pressure monitor set for 8 tires for $380.

So far, the Maxxis tires have a little over 10K miles, I typically drive between 62 & 64 mph, and so far, I've had no tire problems, & although I routinely check their pressure, I have yet to add air to them (ie, they've kept their original approx 65 psi pressure).

Bottom line: While I am a life-long advocate of Michelin tires, given modest trailer driving, the E-rated Maxxis tires om 15 inch rims have appeared quite satisfactory on my 27 FB so far.

After getting advice from Vinnie at Vinnie's Airstream Repair, we bought 16" wheels and Michelin tires.

To clarify. Based on what I can see in your picture you did not have a classic "blowout" or more technically accurate "Run Low Flex Failure".
What you had was a tread separation. Yes it still lost air but that was after the structural failure.
Did you record the tire DOT serial? Have you filed a complaint with NHTSA?
Can you post the DOT serial here so we can ID the tire plant that made the tire?

The Root Cause of tread separation is completely different than the cause of a Run Low Flex failure. If you don't correctly ID the cause of a failure You are only making a wild a$$ guess on why the tire failed so may not be taking the appropriate steps needed to avoid a repeat.

Tread Seps take many hundreds if not thousands of miles to develop so your travel speed and conditions just a few minutes before the failure are not a good indicator of the cause. Run low flex failures can happen in 10 to 30 miles and can be avoided with the use of TPMS.

Tireman9 08-16-2016 10:57 AM

15" vs 16" in itself will not address tire durability issues.
What you get with the switch is a significant increase in the selection of tires. With more sizes, types and brands to choose from with 16" you have a better opportunity to select a tire that will provide significantly better durability that the limited selection of 15" tires with their lower load capacity.

carl2591 08-17-2016 08:03 AM

another great thread on tire issues presented in a very thoughtful way by many.

I don't have a dog in this hunt as the 2005 classic I bought had 16" rims and new Michelin LT tires installed.

But in reading post by other I would be more inclined to do the switch if I put more than the weekend user type of mile on one.

I also read the Maxxim ST tire story in Trailer Life and it sounds like a good tire.. They stressed the fact of the development and research labs in the US., but for some reason they decided to make the tire in foreign lands. Not sure that passes the smell test to me.

The manufacture of the tire is just as, if not more so, important than the development of the tire.

For me and I know others the Michelin LT tire is the best way to go.. and for all the ST tire disciples if you want to keep using the ST tires and feel that right for you go for it.. and I hope you never have a blowout at speed..

Thanks. I also hope no LT tire users have a blowout either.

Have you checked the date of manufacture of those tires, which might be as early as 2003? Every tire has the mfg. date (week/year) coded on one side. If your tires are 13 years old, they are probably overdue for replacement IMO, just on age alone, regardless of outward appearance and/or miles traveled.

If you bought a used trailer with newer tires, it is still a good idea to check the mfg. date IMO. On our new 2014 FC20, the tires were mfg. in the middle of 2013, meaning that they are 3 years old, and thus have 30% less strength +/- compared to new, from what I have read. No thanks! Time to make the swap to 16" Sendel wheels and Michelins before the next major trip.

Happy Trails . . .

Peter

Correction carl, I just now saw in your signature that you got the trailer in February of this year. It still might be good to check the tires' mfg. dates?

Via Adventure.AS in another thread, here is the mfg. date info:

carl2591 08-17-2016 04:18 PM

yeah i have checked.. the DOT code show the tire to be now 3 yrs old. I and the PO keep the tires covered when not in use was well.

I had a set of LT tires on a heavy carpet cleaning van that were over 10 yrs old when i got around to changing them out. The side wall were cracked to a large degree and the tread depth was still above the 2/32 bar. this was a e-250 extended van we carried a 600 or more lb cleaning machine, 125 gal of water, hoses etc.. when i went across scales it was close to 8100 lbs with door sticker rating at 8500 GVW.

I try to make sure the trailer get moved at least every 60 days for at least 30 miles to keep the tires moving so to speak..

I plan to replace them in 4 yrs before we go full time.
