Getting a new set of tires

I made some comments a while back about the tires on my RV being 10 years old but still good because of not going anywhere. They have been blocked off the ground and protected from the sun's rays. I spent nearly 20 years in the tire business and during that time we decided whether a tire was safe or not by condition much more than by age.

It's obvious to me now that I was wrong, and that materials and manufacturing processes have changed. I suspect they have learned to manufacture a tire that looks good and may perform well for a time but has no long term value.

My awakening came after close inspection of one of the tires that was leaking very slowly and finding air seeping from the sidewall not through a puncture, but through a crack so small that it was almost impossible to see. So it's off to the tire store for a new set of shoes before we leave on our trip to Arizona in a few weeks.

I'm sorry for doubting any who advised to change any tire over a few years old.

Speaking of old, I'm not mentioning how long it has been since I have been in the tire business

Long story, but I learned the hard way about trailer tires. Had one blow while traveling across southern Ca.. It changed my plans for that day. Luckily I didn't have any trailer damage, but a lesson learned. The tire was 5 years old and looked great, I thought.

Pulled a trailer with new looking old tires from NC to SD, long story short; first blowout on day one, second on day two, day three changed the other 2 tires and made the rest of round trip without further issues. Then spent lots of dollars fixing trailer from the damage.

I read somewhere that some tire wear (damage?) may occur on the inside of the tire and not visible on the outside. I've read too many stories about tire explosions so I replace mine at 5 years no matter what they look like. Glad you are having yours replaced before any damage.

I replaced mine back in the spring when they were 4 years old. I know from age they should be good for 5 years'ish, but they were the original OEM tires and Load Range E. Having weighed my 5er I know they were loaded to within 300 pounds of their max so I replaced them a little early with G rated tires just before my trip to the Florida gulf coast for the summer. I sure felt more comfortable on that tow as well as the return trip this past Tuesday.

One thing I noticed from the original E tires to the new G tires is the lack of pressure loss while sitting. My old E's would need to be topped off a couple of psi every month. The new G tires only dropped 2 psi over 4 months and each tire was almost exactly the same. I check my tires every month while parked.

Three to five years is the projected life of most trailer tires. It is suggested that they be replaced when they are 3-4 years old regardless of tread life. The tires on our new Jayco were already fourteen months old when we purchased it new so always check the manufacturers code on the side of the tire to determine the actual age of the tire. Look for "DOT" followed by 4 numbers. The first two numbers indicate the week of manufacture (01-52) and last two numbers are the year of manufacture.

5 years is also the age limit for my E range 5er tires. Just won't take the chance.

Ya pays your money ya takes your chances... Ever been behind an RV that the tire was shredding on? to me it is not worth the risk.

I've been down the same road!! Blew a Marathon that was in its 6th year on our trailer. But there was where my problems really started!!! Came home to my local tire merchant that I've used for years on the farm and told him I wanted a high quality tire for replacement . He mounted up 4 new BCTs on our unit. A Chinese tire!!! I wasn't even smart enough to question them.. I had bought tires from that dealer for 30 years. The following summer I blew the first one in South Dakota with body damage. The way it exploded, I was certain that it not from road debris but was structural failure. Blew the second tire in Nebraska. No damage this time but the same kind of explosion. We changed the tire and immediately went to a tire dealer in the next town. It was Saturday afternoon and I explained our situation. He wasn't sure he any replacements that weren't Chinese built. I told him I would just camp in his lot until he found me tires built in the US. Turns out that he had Marathons that were built here in the US. Never again will I except Chinese built tires!!! That local tire dealer that sold them to me lost a good account....

Unfortunately, Goodyear Marathons are no longer made in the US either. Like others, I have researched and not found any US made trailer tires. Today, US tire makers spend all of their resources building car and truck tires. When we bought our 2011 Jayco Pinnacle several months ago it had Goodyear Marathons with less than 350 miles on them. Within a week I replaced them with Maxxis 8008 tires. In my research on Maxxis trailer tires in a number of RV forums, I found very little to no complaints on them. I encourage others to do their own research. I did not want Chinese tires either, even though the Marathons had very low mileage on them.

One year ago while traveling with our former Keystone Raptor fifth wheel, we experienced a massive blowout on the rear axle passenger side tire that did $3,200 damage. Tore up the side sheet metal, the plastic covering under the rig, bent the rear entry steps and twisted up aluminum fender trim. I always pay close attention to tire pressure because of the many experiences I've read about in the RV forums I frequent. No matter how well we keep tabs on our tire pressure, if a slow leak starts the tire will heat up and blow. I now run with tire pressure monitors.
