Just a follow up on a post I made about a year and a half ago.

We changed out the tires on the 5th wheel after 5 years of service they are Goodyear G-614 tires and still looked good .But with the advice I received here and other places we changed them as a proactive measure. As and experiment I placed the 4 old tires that still showed no sign of wear on a flatbed farm trailer that I haul equipment and hay on with the idea of running them until they blow .

 

Fast forward to last Sunday I was loaded and moving about 15000 lbs. of tractor and implements from 200 miles away back home. total wt. was in the 25-28 K range . The first of the Goodyear's finally let go by throwing the cap ,this was a rear tire on a 3 axle trailer and during tight loaded turns is generally the one that slides., air pressure was good the tire was at 95 PSI even after the cap came off.

I plan to keep running the remaining 3 at least until the next one goes but did find it interesting the timing from changing these tires off the 5ver and the time remaining on the tire.

 

To sum it up its a matter of do you feel lucky. IMHO change your tires at or shortly after the 5 year mark or you are taking the chance of a blowout that could remove the side of your house.

 

Thought I would give a final update regarding this . The remaining 3 G-614 tires are no more . I left out last Monday (9/19/16) with the same load going to the same place in East Texas . Less than a 100 miles and the 2nd tire blew out and before I got home the other 2 let go.

Long story short on an RV trying to get that extra year or two out of tires is just not worth it in my opinion .

Completely agree. Considering the relatively low cost of tires in contrast to the amount of damage a blowout can cause.. it just isn't worth it, IMHO also.

 

One other factor to consider. When you are running your tires near max capacity and you have a blowout.. the weight that was being carried by that single tire was just transferred to your remaining tires.. especially the tire opposite the blowout. Possibly overloading them and potentially causing damage and accelerated breakdown. It's not at all uncommon to have another tire let go on you shortly after an initial blowout. Just as Tex Bigfoot experienced.. one blowing right after the other.

 

It's generally best to, at least, replace both tires on a single axle after a blowout, but ideally, all tires should be replaced at the same time.. or at least "put it on the books" to replace the remaining tires at your earliest convenience.

I have always been in the conservative group on replacing tires base more upon age than tread-wear. To me it is a matter of the acceptable degree of risk involved. Not only can it be a safety issue, but I have seen some terrible damage done to an RV by a blowing tire.

[Alie&Jim's Carrilite]

Our Carrilite came with brand new tires. Had less than 500 miles on them..... but they were all 4 years old. They had sat on the coach on the dealers lot, in the factory, in the warehouse, for 4 years. The first one was a catastrophic blow-out, the 2nd lost its tread but held air, that last 2 were replaced with the 2nd.

Wear is not the issue. The issue is Time, under pressure and overloaded.

95 psi seems a little low for carrying that load. Maybe the tires over heated and caused the failure?

I treat mine with 303 aerospace a couple times a year to keep the sun from drying them out.

i think that it was in my original post regarding this but the trailer in question is a 35' plus dovetail 3 x 7000 lbs. axle flatbed. The tires where not overloaded.

 

It was just a simple real world experiment, nothing more.

Living in a 36 foot DP and replaced tires at 5 years for same reason. We were setting out to drive across the country, yet again. I hope I am still RVing when the new tires time out! It wasn't worth waiting a year just to see if they would make it.
