Duravis 250 vrs XPS rib tires

[inlinesix3million]

Thank you sir. I googled images for that and it came back as a great looking split-spoke. Did you have to determine the back spacing before ordering, or is that somehow standard on a trailer
wheel? I intend to ask Arctic Fox what their 16's will cost me( assuming the back spacing is the same ) They appear to use the same wheel appearance on the 15" and 16" for their 2016 TT. It is
a black/silver split spoke which will fit with my theme perfectly. My Trailer gross weight rating will be 10,000. Over engineering is definitely welcome on the wheels/tires.

All, or nearly all, trailer wheels run a 0 offset. The ones that don't are a very rare exception.

Look at the placard on the left front corner of the trailer. It will list the GAWR. If that number is above 6,000 then LRE LT tires are out! You size tires to GAWR not the actual lower loaded weight! By law they have to meet or exceed the GAWR.

You are saying it is illegal to use the not enough tread for driving in the snow tires (2680 weight rated) from my truck on my gooseneck flat bed that has 6000 lb axles? Where is that written?

It's not written anywhere, at least not in the states I have looked at the statues on.

Now if you have more than 5360/axle and only 5360 worth of tires then you are illegal.

So load up to your tire rating is they are less than axle rating.

EDIT: It looks to be a federal reg, not state... at least for Idaho.

49 CFR 571.110 covers vehicles with a GVWR < 10,000 lbs, but Section S4.2.2 is interesting:

S4.2.2Tire load limits for multipurpose passenger vehicles, trucks, buses, and trailers.

S4.2.2.1 Except as provided in S4.2.2.2, the sum of the maximum load ratings of the tires fitted to an axle shall not be less than the GAWR of the axle system as specified on the vehicle's certification label required by 49 CFR part 567. If the certification label shows more than one GAWR for the axle system, the sum shall be not less than the GAWR corresponding to the size designation of the tires fitted to the axle.

S4.2.2.2 When passenger car tires are installed on an MPV, truck, bus, or trailer, each tire's load rating is reduced by dividing it by 1.10 before determining, under S4.2.2.1, the sum of the maximum load ratings of the tires fitted to an axle.

Good info. Thank you.

Now to relook at my state statues and see if I can find anything new.

That second bullet is commonly overlooked by guys with pickups and P rated tires loading them to the sidewall max. It does not apply to LT tires.

EDIT: A search brings up nothing in Idaho.

I do know that the federal CFR's allow for modified weight placards based on reasonable modifications. So if you want to run lower rated snow tires then run a lower GAWR placard.

States generally follow and enforce federal weight regs. SNOKING

Yeah it's a combo of both. States don't always follow the fed regs thou, just look at Colorado, Oregon, and Washington... different topic but a fed vs state issue.

It is not impossible to have LT tires on a 6K axle and meet state and federal regs, even with snow tires.

The Blizzak W965 235/85R16 is enough tire for a 6K axle.

7K axles are hard to match as you need bigger than a 265/75R16 which is already going to be hard to fit on many trailers. A 265/75R16 only gives one 6,830lbs.

But as the federal CFR's allow just drop a new placard on it. It's a reasonable modification and legal.

 

[GAmes]

Interesting, but no worries. My data tag came off years ago. I had to borrow a stamp kit to put the vin on the frame.

 

[RVTRKN]

Thanks for everyone responding to this thread, it has been informative. GAmes, I think that your in a grey zone with that trailer not having a GAWR tag. I'll admit I know very little about commercial regs, but I do know that interpretation of fed/state regs can vary from the officer that wants to inforce them. Also, the State's can only exceed federal law but must inforce the federal laws, so meet or exceed federal law. As far as just having the VIN stamped on the trailer, I would be OK with it, if I was the officer, but I would take a quick look at the frame and axles to see if they seem to match the tire's specs. It goes back to an old argument about the axles, having homemade axles using a 1/2" rod welding the spindal to support hubs that can handle a wheel rated for a tire that makes up a 6K pound axle, would catch the eye of an officer.

 

[GAmes]

I don't use the trailer commercially. If I did the tires' rating would exceed the GVWR. However, there is a provision in FMCSA rules covering missing data plates. It isn't focused on tires or vehicle's actual GVWR though. It's focus is drivers license class, whether or not a CDL is needed for the GCWR. It allows use of the actual weight of the trailer added to the GVWR of the towing vehicle. I have towed several older RVs on the job that the data plate isn't legible and that provision covers me.

I put my first couple hundred miles on the R500's this weekend and I am quite pleased. Braking action is better and the trailer seems a little more stable on winding roads. It tracks great up to 70 and shows no issues. I did not have any issues prior, but these do seem to be slighlty better from the drivers seat.

Do you have any more miles on the R500's now? Do you think it has affected your fuel economy at all?

I have another 900-950 miles on them and so far so good. I would say around 100 of those are on dirt/gravel and they do great.

I haven't noticed a change in economy either way.

 

[MoparBob]

For the folks that would consider the R500 due to weather and road conditions, did you consider the M700 HD too?

Thanks for the update!

I briefly looked at them but I didn't like the tread design for a trailer tire.
