New tire question

Picked up our leftover 2012 Windjammer wearing a set of original China Bombs. They survived maybe 15 minutes before a blow out.

What's the current thinking on the best replacement? I've done the search, what's the pecking order.... Maxii, then Goodyear? What about the Carlisle radials?

Thanks in advance, don't want to experience that again.

Depends on who you talk to.....

Mine are Maxxis but I have heard good about Goodyear and Carlisle also.

Was the RV new? If so why didn't the dealer stand behind the tires?

re replacement tires it would help if we knew the OE size & infl numbers as well as the real measured tire loads.

RV was an unused 2012 Windjammer with original tires. They were 225 75 15inflated to 50 psi, unsure of load. They are C rated and I plan to go to E rated or D at least.

The tires didn't look pretty, no surprise as to the blowout, only as to the timing. I don't think they should be warranty, they succumbed to the elements.

I just don't want another blowout.

why the increase in load range? The load range of the tire should be commensurate with the axles capability. Seems like dry rot was the culprit here not that the tire was overloaded, right? An 8 or 10 ply tire seems like a waste of money. Make sure you get quality tires and keep them covered when parked.

OK
As a minimum you should file a complaint with NHTSA. I don't think the RV dealer is being a responsible seller as most reputable dealers have the tire warranty clock start ticking on date of sale. Sure hope you got a great deal on the "AS-is" RV.

Until we hold the tire company responsible for the stuff they sell we, the RV owners will never see an improvement in quality.

What is the claimed GAWR & GVWR on the plate on driver side, outside driver front side of the RV?

You need to find out the max inflation rating of the wheels, in writing as you may need to change wheels too.
If they refuse to give you an inflation max then you need to find wheels in your size that came on RV delivered with LR-E tires.

I hear that eTrailer can help with wheels.

We have a 3025W that had the China bombs on it. I started to see splits in the side walls after just one year and 2500 miles. I always kept 50 psi in them and although we never over loaded the trailer it was always right at the max that those tires were rated for. They always looked like they were low although they weren't. I put Carlisle tires on this summer and keep them at 70 psi and it made a huge difference in the way the trailer pulls. It don't seem to sway or wallow around at all like it did before and feels much more solid. Also when its set up it don't bounce near as much as it did. I think the E rated Carlisle tires are great.

Tireman, I've looked at your blog and thank you. I can get the sticker numbers FWIW. I will make a report.

I bought the trailer at auction, it appears new, maybe from a bankrupt dealer. The tires had varying pressure, low 38 (one that blew) and others 42-45. I filled all at 50 before moving.

I got a really good deal and can afford to spend a few bucks on new skins. The trailer has the nice aluminum wheels and I will check inflation numbers, thanks for the tip.

Nice to hear from a pro, thank you. Is there a brand you like better than the others?

Are you confusing Load Range i.e. "C, D E etc which replaced the old , out of date, misleading "Ply" or number of layers of reinforcement cord, with the load capacity that is given in pounds?

It is the air pressure that supports the load.

It is the body and belt strength that retains the air pressure.

All the "ply" in the world will not support the load if the inflation pressure is zero

So you went from LR-C to LR-E. I'm not surprised the trailer bulls better and has less wallow.

I am compiling a database. Could you post your individual tire loads from the scale readings? Thanks in advance.
