'09 Cimmarron, 4 Horse with 12' LQ. Bought new in April '09 and has about 15k miles on it-full weight is 17100 lbs. Trailer is pulled with a 4500 Chevy and the front sits 3" higher than the rear with the adjustable hitch all the way down. Ideally, I would like to drop it another few inches to run perfectly level but the hitch mechanism is in the way to drop further.
Problem--the tires on the front axle are wearing on the inside (indicating overloading) and the rear tires are wearing on the outside (indicating not enough weight) on the torsion axles. The tires are Goodyear G614 RST Load Range G-236 85R16. Axles are Dexter 7500 lbs. Bearings appear to be tight.
Question-besides rotating front to back on the tires, should I raise the hitch a few inches to transfer weight back and make it 5" higher in the front? This weekend I am going to try to weigh each axle to see the difference. If significant, will probably call dealer to discuss. Wear is really noticable.....

I would check the air pressure in them, most of the time when a tire is under inflated the outside will wear faster than the inside. And if you over inflate a tire than the inside will wear faster than the outside. So thats what I would check is your tire pressure.

Thanks! Max on the tire states 110 cold. All 4 have been run at 105 sense new--I try to check before every big trip.(several times a month).. The abnormal wear is the inside shoulder only on the front, and the outside shoulder only on the back tires.

Sounds as if you have things figured out. If the load isn't being equally shared by both axles, you will definitely have uneven tire wear patterns.
By weighing your trailer and axles, you will have the information you need to determine the source of your tire wear problem. By then adjusting the trailer's trim, and re weighing, you can even out the axles' loading.

I had a flatbed truck with ball on top of the bed. With the coupler all the way up, my front trailer axles barely touched. All the weight was on the rear axles, and it wore the back tire on the passenger's side bad on the inside. I was trading the truck anyway, and the new truck can let the trailer ride level. Haven't had a problem since.

Have you checked the load rating on your axles? I have seen trailers built with less axle than needed, and they were ALL LQ trailers. Find yourself a reputable shop and let them help you with this problem.
You shouldn't be experiencing wear at 15K miles. Check tires first, axle weights second and then axle ratings.

I would say have the axles on the trailer blocked so it will set level!
