Welcome to HTW...!
What size trailer do you have? What size are the tires and axles?
I don't know first hand because I have never owned nor have I ever pulled a Pegasus. Talked to a hauler a few years back that said he could always find something to reweld on his Pegasus. He said it was built so stiff and ridgid that it would literally break itself apart, trailer would not flex, too solid. He also said that it would eat those four 245-75x17.5 tires like they were candy. He never did say what it weighed loaded, but he could haul as many as 9 horses. Trailer was a 6 horse head to head with stall area for 3 in the center isle. Don't know if the trailer had a steel frame or if it was all aluminum but it looked heavy. Looked as it it should have been sitting on dual tandem axles........ Trailer looked to me like the axles we too far forward, axles were probably about overloaded with not enough weight distributed onto the hitch of the tow vehicle. may have been built for a class 4-5 truck. This trailer would have mashed a 1 ton pickup.... Trailer was being pulled with a F-850 Ford single axle tractor.

I have the 44 foot magnum plus that holds 9 horses also. It has 10,000 lb axles. 235/75/17.5 tires. I blew 9 tires this year and 4 more in November and December last year. I took it back to Pegasus twice and they said it was in perfect alignment. I took it to a local certified alignment shop and has negative 7/8 camber at all 4 positions. This is way out. Axles need to be bent back to 0 or positive 1/8 camber. There solution is to put three axles on it????? They said it was spec'd as a show horse trailer which is the most ridiculous thing I've ever heard

That size tire in a load range "G" is good for 6000#, it's also built in a load range "J" (18 ply)... But, with the axles that out of whack, nothing is going to survive.... Your trailer got air ride suspension?

My trailer weighs 17,000 empty. With 7 horses it weighs approx. 24700lbs. That puts the tires over capacity by 700 lbs. And they sell this as a 9 horse trailer. Sounds like false advertising to me. If anyone out there has had similar issues with Pegasus please respond with your input. Thanx

What is the ACTUAL weight on the axles???...I assume that they are expecting 20 to 25 per cent of your total weight to be on the PIN...so if your GVW is 24700 and we subtract 6175 lbs(25% of GVW) that are supported on the pin...then your axles are supporting 18525 lbs...so a long as you are not massively out of balance you are within the 10000 lb limits of your axles...Haven't done the math on the tires yet...

Actual weight on axles when trailer is empty is 11,090. Pegasus has trailer listed as 26000 gvw. From what I understand, the gvw cannot be higher than the weakest part of the equation which is most always the tires. If we have 235/75/17.5 tires that have 6000 capacity each that only comes to 24000??

The GAWR cannot be high than the weakest link. In your case, the axles at 20,000. The GVWR can include the weight that the tow vehicle carries, which in your case is figured as 6,000, giving you a total GVWR 26,000. This is a 23% tongue weight.
Going back to what Paul was saying, if your trailer weighs 24,700 loaded, your putting 19,019 on the axles, which is still within the axle limits.
That all being said, it doesn't help any of your axle problems that you are having. The negative camber is a sign of overload on an axle, so at some point you have been way over, or the axles were never right to begin with. The best thing you can do is get a weight with the trailer fully loaded so you know exactly what type of weight you are putting on the axles. Calculations are great, but what works on paper doesn't always work in the real world.

Just to be sure we are on the same page...Was that 11090 with just the trailer wheels on the scale?

Yes, 11090 with just the trailer wheels on the scale. No horses loaded
Then the next question is have you done a several backups where you were in a "jackknife" and were pushing the trailer around by sideloadng your axles on a hard surface???

Yes, unfortunately loading horses at the racetrack is quite tight trying to get around the barns and there is no easy turn around. I was always told to try to keep moving not too slow and not too fast when making these tight turns. There is no way for me to avoid these manuevers

Well, unfortunately...that may be the cause of your camber problems...the next time you are sideloading your axles...check if you can actually see the wheels move out of their vertical alignment...

Stay as far away from these things as you can...they had a good year in 2005, most of the design problems were fixed but they don't hold up both earlier and later years are junk. Pegasus won't stand behind them...there have been fatal accidents pulling them to both humans and many many horses.
