I have never heard anyone rave about how great their Loadstars held up when in use. Will be eagerly awaiting your report.

BTW, lots of irony in this post. Be careful out there.

They should be good for my weight. I think the next chance I get I will get it weighed. I always travel with no water in the tanks and about the only thing additional packing I do is fill the fridge. everything else that is in it stays in it. The most important thing to me now is the tire pressure and cheching the lug torque. The brakes seem to be fine on road testing and I have not noticed any issues with heat from the axle caps or brakes. The more reading I do I find that max cold tire pressure is the ticket.

Wow! 35 PSIG?!? What is the weight of your trailer? What does the nameplate data on your trailer say for recommended load range of your tire, and recommended air pressure? (A required tag).

Your tires will state the load rating/load range, which will govern the "max" tire pressure. Load range "C" for example (a very common load range for trailers) is max 50 PSIG. I was running my old Carlisles at less than 50 and they didnt last very long at all. Then I upgraded to load range "D" Maxxis (max 65 PSIG) and I am very happy. Kinda finicky about my pressure...keep 'em at 65 (cold) and they are wearing very nicely.

The Carlisle tires have a good rating for my 23b. I think I will take it down to the local truck stop and get it weighed just out of curiosity. It stays close to same weight all the time except when I load the fridge and about 100lbs of miscellaneous crap to travel and I do not carry any water in my tanks when I travel. I was more concerned with how it will ride with the max cold tire pressure at 50psi as compared to how I am use to it riding at 35psi. I know that speed plays a big factor in that as well. Me being a motorcycle rider as well I am always traveling in a caution defensive mode so I never go over 60mph with the TT in tow. Thanks for all the input!

Was just curious about the weight ratings posted on your sticker for your 23b. From the Jayco brochure, it looks to be about 3990 empty (UVW) and 4950 max loaded weight (GVWR). I would bet your side panel sticker indicates Load range C tires, inflated to 50 PSIG. Like said before, lower pressures cause more heat and premature wear (and blowouts!). Your tires will also have a speed rating listed on them, typically 65 MPH...pay more money and you can get a higher speed rating (I dont typically travel my trailer >65). Its just good overall to really know your tires and your weights.

OK NEW DILEMMA!!!! The problem the sticker is gone and the manual calls for 35psi.... Today I stopped and looked at another Kiwi and took a picture of the sticker.......The sticker say ST175/80R13B......35psi..[ATTACH][/ATTACH][ATTACH][/ATTACH][ATTACH][/ATTACH]....needless to say I have different tire size than what is on the sticker! I don't know what rules that changes but, I know I put back on it what came off, ST185/80R13. It sounds crazy but I don't think that the TT has traveled very far in the last 10 years. I know the furthest the previous owner took it was a 3hr drive. I have seen the cold pressure on the new tires but, not the speed rating. They are load C tires just like the old ones. Also a pic of one of the tires I took off[ATTACH][/ATTACH][ATTACH][/ATTACH]

If I am doing this correctly the load per tire is 1480lbs x 4 = 5920lbs. I think I am in the 4500 range loaded.

Load C tires are good to 50PSIG...(and the closer you run to max, the better they respond/wear/etc.) The sticker you looked at had load range B (ST175/80R13B) @ 35PSIG max pressure. What is the weight rating on the tires you are running? (my load range D tires have weight rating on tire listed as 2150lbs per tire...my old load range C tires were 1820 lbs per tire) What is the weight of your TT? (and how old is it that the sticker is gone? How about the weight rating sticker on the inside of one of the interior cabinets?)

Hmmm... Ok...13 inch tires tells me this is a very light/small trailer. Not the 23b I am used to. (Pop-up?)

The following is an example of the difference in load carrying capability of a C load range tire at 50PSIG or 35PSIG:

1360 pound capacity x 4 = 5440 pounds capacity at 50 psi. But only 1100 x 4 = 4400 pounds capacity at 35 psi.

From what I call tell (without knowing the year of your kiwi), your UVW is probably 3945 and gvwr is 4950.

I'd go with 50PSIG (for LRC tires)

It is a 2000, jayco 23b kiwi hybrid. In the photos I posted you should be able to see the max is 50psi at 1480lbs x 4 = 5920lbs. I think I am in the 4200lbs. range loaded.

I believe your number are right, Jason.

On the speed rating: ST (special trailer) tires are rated 65mph
