I have a 1994 Fun Chaser 22L. I purchased it in 2017 with very low mileage on the original tires. I changed them because of their age. I've put just over 20,000 miles on it since the new tires and 3 of them are wearing very heavy on the outside. The left front tire looks like new. I contacted a axle alignment shop and they told me there is not fix and I would need to replace the axles. Does anyone have a better answer for the problem?
Do you rotate, is it Tracking correctly? 20,000 miles on trailer tires is great. repack the bearings, slap some new tires on and replace the brakes. Keep on trucking. I think if you had a bent axel it would dog trot. If you're traveling that much put nice truck tires on and rotate them. Take the weight off during storage with some cheap jack stands. (This is the never ending question to truck tire or not to truck tire)
