Something whispered in my ear tonight… and told me to repost this article on trailer tires.


I am a bit freaky about tires because during one trip several years ago, I had three trailer tires blow.


I couldn’t  understand it.  The tires were practically new.  I had probably only driven a few thousand miles on them – if that.

How could they have failed?


At that time, I was preparing to move from Oregon back to California.

Consequently, I was busy and my trailer just sat.  New tires and all.

THAT was the issue.  Or one of the issues.

The guy at the tire store who helped me with the last of my three blow-outs told me:

(I need to say here that I was quite freaked-out to have so many scary events in one road trip…)

He told me 2 very important things about tires:

1)  Old tires will not last as long, no matter if they have good tread

1a)  Sometimes ‘new’ tires are actually old tires that have been on the shelf for years even if they appear brand new

1B)  Below is a guide on how to check the age of your tires.

2)  If tires sit in one position on your trailer – in the sun – they will fail sooner than later.

2b)  Move your trailer so the tires are not constantly in one position – move it just to move it.  Sun or no sun.

My tires were new but they had sat in one position, in the sun, for a while.

That is why they blew…

Part of my "Start of Spring" cleaning was to get new trailer tires. (Yes, I need to wash the foliage off of m y wheel wells - next weekend's chore!)

I’ve never forgotten that trip.  So, I am a bit over the top about checking my tires.

This year, I knew that my trailer had less use than usual and I also knew it had been several years since I had purchased new trailer tires.

My tires were not thread bare, but due to the time they spent parked and just because they were older in age, I decided to get new tires – so I could rest easily this riding season.

The same goes for truck tires…

I bit the bullet and got new tires for my truck as well... (Yes, my truck is old... but it works well - especially with new tires!)

I found the article on this website:

The Hidden Danger of Old Tires – how to read the code.
How old are the tires on your horse trailer and towing rig?

“…The following quick tip can keep you and your horses rolling along.

The problem is that tires, like any rubber product, degrade over time
and could present a significant yet hidden safety risk regardless of
tread depth.

Trailer tires 6 years and older can fail/blow out when traveling; also
under inflated tires get hot at high speeds causing sidewalls to fail
and separate from the tread. When getting a trailer or replacing tires
on any vehicle insist on tires manufactured within the past year or so.
Just because a tire hasn’t been ‘used’ or put on a vehicle does NOT mean
it is NEW.

Tires are manufactured with a date code, 4 digits long, which represent
the week and year the tire was made (For example 3211 is the 32nd week
of 2011 while 0598 is the 5th week of 1998). This code is on the tire
usually in a circle or indented oval following the other sizing numbers
and info on the tire. (The code could be located on the inside sidewall
if the tire is already mounted on the vehicle…check for it. Your
safety is well worth the extra effort!)”

    In all actuality, it’s a customizable, multi cellular caravan that’s a step up from the Airstream or your typical campers. The same faceted surfaces show up on the mostly white interior making this a great option for people who don’t want to leave their modern aesthetic.

    Several years ago, right after this information was posted the first time, I went out to check the tires on my horse trailer. THANK YOU for this blog because there was a big fist-size bubble on the sidewall on the inner side of one of the tires! I never would have known, and my ignorance could have been catastrophic. Again, thank you. I’m sharing this with everyone I know.

    WalMart is a BIG offender when it comes to selling “new” old tires. Two blowouts later, both front tires a couple months apart, after replacing both less than 3,000 miles before (in fact, just when I previously had my oil changed at a WalMart auto center. Although WalMart replaced both (they had to – I had the warranty and proof of purchase) they dinged me for tire disposal fees for the shredded ones. THIS time I insisted on a current year tire. And as soon as budget allows (I was unemployed at that time and still recovering financially) I will upgrade all four.

    Thank heaven it was my passenger car with triple A auto club for towing, and not my dually hauling the trailer with horses in it. BTW triple A won’t help you if you’re hauling a trailer!!
