Excuse me if this should have been put in tires and wheels section.

Looking for a new set of tires for my 28’ enclosed. Tandem 5200 axles. 225/75/15 load range E. Have a set of power king towmax on it now. Those were on it when I bought it so ran with them for a season. Had a bulge come up and one blow out last year with them, so I’m going to replace all of them before this year.

Tire rack lists the power kings and a Goodyear endurance in that size and weight rating in a trailer tire. Everyone have any experience with the Goodyears?

This trailer gets pulled a few times a month all summer on trips ranging anywhere from 20 mins down the road to 10+ hours away. Always keep up on air pressure and they’re covered up when the trailers sitting.

I have Goodyear Marathons on my 5vr and had a blow out on the interstate last year coming home.

They are coming off as soon as the new camping season begins and will either go with Sailuns or Michelins but I suspect that my camper is much heavier than yours as I am going with 14 ply tires due to the load.

Goodyear has a new trailer tire out now that is made in the USA. Pretty much everything else out there (ST) is made in China and are garbage. Including Goodyear's old Marthon tires which were also garbage. Cannot tell you how many Marathons I went thru on 5-6 trailers before I finally gave up. They were made in China too.

The new Goodyear's go under the Endurance name. They're still fairly new but all the reports so far are encouraging.

As long as you stay with any ST tire in a 225/75-15, you're going to have problems, IMO.

Solution?
All you need is an extra 1/2" in height/wheel well clearance....
That^ allows you to move up 16" wheels with the same 6-lug bolt pattern ('bout $50/ea).


With 16" wheels, this opens up a whole market of LT tires to run.
LT225/75R-16s vs the old ST225/75R-15s
I call 'em the Abrams Tank of trailer tires, the Bridgestone Duravis R250.
A commercial LT Steel wrapped casing, suitable for retread/regroove.
Sidewalls like an iron fortress. Nails run and hide in fear.

Speed rated for 99mph, these will age out before the tread wears out on your trailer....the last trailer tire you'll have to buy for it.

It's an investment for sure, but your days of spending more time looking back (blowout) vs looking forward when trailering...will be long gone.

Mounted on the 12k lb 5er....no sidewall squat.

The 16” tires don’t have enough rating for 7,000 lb. axles.
You need to check out Sailuns S637 G rated tire excellent rating.
The ST235/85R-16 G @110psi is rated at 4400lb rated 3540 @ 80PSI check Simple tires
Tried to copy and post chart could not do it. These are rated commercial rated trailer tires.

I see it’s a Canadian Company, so do you know if the tires are made in Canada? That would be much better than the Chinese tires.

I know they are made off shore. I do not recall which country but I know when it comes to commercial tires they have to meet standards. Here is a email address of a Sailun rep. [email protected] Go to any RV forum and do a search on them and you will find they have a very good rep with people that have heavier trailers with 16" wheels.

Doubtful the OP has 7k axles, running 225/75-15s
Where did you find the ratings for the R238?

Now you get into the differences in construction and how ratings compare on LTs vs STs, where one is overstated, the other, understated. How all of the U.S. mfrs dumped their equip for making STs, to CN....the problem is not the country of origin cutting corners in mfr'g, it's just the crap design of an ST that is the prob.

But that's an argument for the RV forums....that has never been solved. :rof

The ratings were on the Bridgestone site. I have 7k axles, so that’s why I was asking. My trailer is coming with 14 ply, 4,400 lb. rated tires, but I’m sure they are Chinese.

It is my understanding that the only ST tire made in the USA is Goodyear Endurance I have them on my 5th wheel. I just put them on last year after ditching my china booms Westlakes. I only had them on for 1 year. The Endurance I think are Manufactured in Georgia.

I didn't find any ratings on it for 16" tires on their sites.
14-ply scenarios won't work with the LTs.
Unless you convert to .5 wheels/tires, which IMO is where those heavy RVs need to be in the 1st place.

Scroll down and you’ll find 16” Bridgestone tire ratings. You are correct, no R238’s in 16”.

Ah, okay thanks. Saw that, but page after page was all .5 wheels, and I gave up.

They have the same rating as the R250s.
