Those are all labeled LT, but if you can order them in bulk, maybe you can change that too. The LT235/75R15 is load rated at only 900kg, which is quite a bit lower than the ones on our RP-179. 

Who knows, maybe all the specifications and sidewall marks are written in chalk?

Here you go, CR857+ tires.  

You can get them as Goodrides, Westlakes, Linglongs, Chengshans, or Triangles. $30-$50 each but you have to buy at least 100 pcs. Bet if you buy enough of them you can get them labelled as ST's or anything else you wantLOL.

+1 to what Wood River Pod said.

The tires that came on our HRE RP-179 are Westlake CR857+ tires. The size stamped on the sidewall is "ST235-75R15", and they are also labeled "For Trailer use Only". They are plainly trailer tires.

They are a special tire (presumably) ordered by Forrest River for (at least) the HRE R-pods, and probably others as well. There is no after market equivalent, and they are also special because even though they are load range C, they are stamped with a maximum load of 2340 lbs, which is way above what a "typical" load range C tire would handle.

If you were to replace these tires, the closest I have found is ST225-75R15. You would want to get load range D in this tire size in order to get a similar/equivalent load handling capability.

The difference in height is only 3/4 of a centimeter (235 mm - 225 mm = 10 mm = 1 cm). And since it is a "75" profile, the height is .75 of the width, or 7.5 mm. This translates to about .295 inches or a little less than 1/3" (or a little more than 1/4" if you prefer) difference in height.

The Westlake 857+ tires that come on the HR's are 235 75 R15's.  They are ST tires not LT tires.  There is no like size replacement unless you go to a LT.  I have posted several times about my frustration trying to find a same size swap.  If I want to replace with ST tire I'd have to a 225 75 R15, which I'd lose about a 1-2ish in height.  Not a deal breaker since I added the risers, but I'd rather not. 

I couldn't find my old post on the topic.  Sorry.  Hope this helps.
Thanks

If you know you have 15 inch wheels you'll be fine with the 225/75R15's, no need to make a special trip.

Just to be clear, and I'm not in any way criticizing Carlisle, but many companies make 225/75R15 LRD trailer tires, so you have plenty of choices.  Smile

Thanks for all the quick replies.  Yes, we have the HRE model 2015 179 and I know they are 15 inch rims.  I looked at them recently and I remember LT 2?5/75 R15 load range C West Lake (originals) and I was thinking the ? was a 3 but easily could have been a 2.  I know many on this (GREAT) forum have suggested the Carlisle Trail for it's stiffer/thicker sidewalls and higher pressure capacity and load range (D).  Maybe I should make the drive to verify the tire size before ordering anything.  Thanks again!

No valid reason I can think of, other than the LT tire tread pattern supporting the HRE's "off road" image.  It will just result in higher rolling resistance and more rapid tire wear. And 179's have pretty high axle, wheel, and tire loadings. 

I agree with etrailer, its a trailer, use a trailer tire. Tire Rack also agrees:

I am NOT a tire expert.
However, I have personally found that the new Goodyear Endurance tires do in fact have a significantly stronger sidewall than my previous Maxxis and the original china bombs. I think the ride has improved and the pod does not bounce up and down as much as before the Goodyears were installed.
I increased the load range and feel more comfortable with the new tires. I have used them for 3 relatively long trips(3000+ miles) and am happy so far.
Just my 2 cents-other opinions may vary

I know this subject came up a while ago but the 'search' function failed to reveal it. Very frustrating.

Please educate me.

?Is there ANY valid reason to use a light truck tire on a travel trailer?

e-trailer 'expert opinion' - "Light truck tires are a type of passenger vehicle tire and as such they are not built with as thick of a sidewall as trailer tires. A thicker sidewall allows a trailer tire to handle more vertical load."
