I had not seen that type of stamp before. I have seen actual max PSI rating stamped on the rims before.

 

The only other stamping is this

 

Here is the spec's on my rims I assume 6/3200 lbs means six inch wide tires and 8" the rim can take 3750 lbs. I run 235/80R16

 

Maybe 6 is 6 lug, 8 is 8 lug? After thinking about it probably not.

I had no psi anywhere just the # rating?

 

They are 8 lug though so maybe so.


here is the spec from the web on my rims:
http://sendelwheel.com/wheels/t06gm.html


T06-66867GM**16X68/6.5+04.903750 @ 110 PSI

 

I went to the manufacturers page and the 16×7HD rim doesn't say psi either just weight rating.

 

Not unusual to have the weight rating OR PSI rating. Sailun 235/80/R16 are rated at 4080# at 110PSI, the 235/85/R16 are rated at 4400 at 110 PSI.

 

Same with me. I only saw the 80psi stamp on the 8 lug rim. Didn't see any indication of carrying capacity.

 

I managed to crawl under the trailer today and look at the rims from the inside.

I could not see a PSI rating, but there may be one that the drum is covering.

I did find the following numbers stamped on the wheel.

Sendel 5134 B3 16x6J - This is the make and model of the wheel, but very little to no information on Google about it in regards to PSI rating.

Max Load 3580 lbs - I am attempting to correlate this rating to the PSI rating.

I have an email out to SenDel to see if they can provide me a PSI rating of the wheel.

More to follow.

 

I'm going to go out on a limb that the wheels aren't good to 110 psi given the weight rating at 3580. Most wheels that are marked 110 are rated to 3960.

 

Looking at the image that Senix posted of his rims weight doesn't have anything to do with it.

 

No response from Sendel as of yet and there is no phone number listed on their site.

My gut is telling me to choose the GY Endurance, but I plan to give it another week or so before giving up on the ability to inflate tires to 100+ PSI on my existing rims.

 

Sendel seems to use a T # for the rims. Were there any other markings on the rims?

 

I saw that too Scott. The only thing I can think of is they changed their number/item codes since 2011. There were no other markings that I could see on the wheel, while mounted to the axle.

Although, it 5134 immediately followed Sendel.

 

Not to side line the wheel rating discussion, but I did get the opportunity to pull our 5th wheel last week with the new Carlisle HD F-rated 235/85-16 tires in place.

There replaced the Cooper LT tires of the same size.

I did notice that at 95PSI there was a tad more feedback from the trailer as to rough roads, this might be able to be adjusted with a lower PSI of the tires. I however will be leaving it alone as it just wasn't that big of a change.

I also noticed that when backing into a site there was much less sidewall flex, as in none. Where as the LT tires did flex and roll on the wheel. Many times with the LT tires after getting the RV in place I would pull it forward a few feet just to get the flex/twist out of the tires sidewall.

Tire temps ran cool when tested with an infer red temp gauge.

I guess the real test will come next month when we head out on a more extended trip.

As a side benefit, these tires are rated only for 75MPH which kept me from getting crazy with my speed. I averaged closer to 70-72MPH which was plenty fast, even for a guy who had no issues with pulling at higher speeds. When it was all said and done I did average .8 MPG more than before. That savings alone in fuel will pay for the new tires in only..........oh who cares.
