Rim Air Pressure Rating

hdmtnrider · 10-09-2016, 08:55 PM

Hi All! I'll try to make this short and to the point. A friend has a 2015 29UDQL5 and wants to upgrade his tires to the Goodyear G614's. He pulled one of this wheels off today and looked to see if the rim air pressure was marked on the rim and the only rating on it was the load rating at 5950# (If my memory is correct). They are 8 lug alloy wheels. He is going to change the valve stems to metal and has a TPMS. So, in saying all that, How does someone find out the air pressure rating or does he just upgrade to the new tires and stay within the load rating?

TIA for your INFO and Time.

I spoke with a wheel mfg. a while back and was told that they don't have a psi rating on the wheels. They will handle any tire pressure requirement up to the rated load.

The GY G614 requires a high pressure (110 psi) rim with steel bolt in valve stems. It's size is 16x6.5". That 6.5" rim width is the only width approved by GY.

Here is a reference.

That's one thing I like about the Sailun S637. It comes in a 6" width.

You're right, I misspoke. I meant: ST235/80R16 but see that I'm wrong.

hdmtnrider, can you double check with you friend and see if the load rating on the wheels are 5950#. If they are see if he can take a photos of the wheels I need to but 6 for my trailer as I had 1 3750# wheel fail last week. TIA

It may be marked on the rim somewhere, inside or outside. When all else fails call/email the rim manufacture.

I seem to remember a post a long time ago, possibly from one of the factory guys on here, that the XLRs all use the same high pressure rim, regardless of which tires are mounted on it. Not 100% certain, but maybe we could get a confirmation on that from BulletBob?

Define fail, please. A leak or did it disintegrate?

Now we can ship the focus from tires to CHINA BOMB WHEELS! I wonder if it broke at the welds, seriously? That has to be a very large and heavy boat, B.

I think the 5950# wheel number is way, way off. The following is from eTrailer.com

Expert Reply:
A 6-lug wheel can be on a trailer that has an axle capacity of 3,500 lbs, 4,400 lbs, 5,200 lbs and 6,000 lbs. The 8-lug wheels on a trailer can fit a trailer with axle capacities of 5,200 lbs, 6,000 lbs, and 7000 lbs, and higher.

An individual 15-inch, 6-lug wheel will have a capacity of 2,830 lbs at 80 psi. An individual 16-inch, 6-lug wheel has a capacity of 3,050 lbs at 90 psi, and an individual 16.5-inch, 6-lug wheel has a capacity of 3,040 lbs at 80 psi.

A 8-lug wheel will be either a light duty 16-inch size with a capacity of 3,750 lbs at 110 psi or a heavy duty 16-inch size with a capacity of 3,960 lbs at 110 psi. There is also a 16.5-inch size with a capacity of 3,530 lbs at 90 psi.

The trailer will have a plate or sticker on it that will list the VIN number. The weight rating of the axle should be listed on that same plate or sticker. Also, the axle could have a tag or plate on it that will list the weight capacity.

You can also tell the weight capacity of the axle by measuring the diameter of the axle. A 3,500-lb. axle will have a axle diameter of 2-3/8 inches and a 6,000-lb. to 7,200-lb. axle will have an axle diameter of 3 inches. Expert Reply:

Maybe our forum wheel / tire experts can confirm or reject this article. I am 99% sure my 6 lug 15s have 2830 stamped inside.

The boat weights 12,500lbs and sits on a 24,000lbs GVW trailer with 8000lbs axles. The wheels were rated at 3750lbs. The weld failed, and 3 other wheels were cracking at the weld. The wheel manufacturer is sending me 8 new wheels rated at 4020lbs. That is the reason I was asking the OP if his friend was sure his wheels were rated at 5959lbs as I would buy a set ASAP. But what I found out is the 4020# wheel is the highest for a 16" 8 lug wheel. The manufacturer is also replacing 1 of my Goodyear G614 tires and repair to my axle ubolts and plate.

Switch to 17.5" and all your problems will disappear. 4800lb ratings. http://www.trailertiresandwheels.com/17.5-radial-tires

WolfWhistle · 10-16-2016, 06:57 PM

looks like we scared the op away or he was pulling our chains with the 5950# wheel rating.

hdmtnrider · 10-17-2016, 08:44 PM

NOPE! OP is still here. My friend is going to have his new GY 614's installed this week and i asked him to take another look at his rim's. After reading e-trailer's reply, it looks like they were probable 3950# and not 5950#. Will post as soon as he has his tires installed.

WolfWhistle · 10-19-2016, 06:43 AM

wow, they put a substantial wheel on those 29UDQLs! Thanks for updating the solution

hdmtnrider · 10-27-2016, 08:06 AM

Update, my friend had his G614's installed Monday and had the dealer look at the rim's. The rating did say 3960# and not 5960#. Sorry for the incorrect numbers in my original post.

SidecarFlip · 10-27-2016, 08:44 AM

Been reading along... I've never been comfortable with a tri-axle setup because of the torsional force applied to the outer axles and rims when making a tight turn, especially on uneven ground. There is allot of tire scrub as well.

Just my 2 cents. Back to reading....
