Boat trailer tire uneven wear

[landry]

Maybe someone ca help me out here.

My tires are wearing in both edges super quickly. Has always done it. I keep them at the recommended 50psi.

I am thinking I should move to a trial tire as I do get flat spots if it sits for a while. I thought maybe this was causing my problem?????? I barely get two seasons out of them - likely about 15,000km max.

If the edges wear, they're under inflated, if the centers war, they're over inflated. I run load range C 530 x 12 on my trailer, recommended pressure at max is 80 psi. I use about 60 otherwise they bounce like a billy goat. Radials are better if you can get the size.

I am at correct psi so I am thinking the tire is a poor choice maybe.

Could quite well be the issue, what size are the tires?

After reading all the talk about tires, bearings etc, I thought I'd check the extra bearings and seals I had stored in the boat - glad I did - the bearings were rusty and useless - then I figured that I'll get a whole hub assembly for the trailer and have that along just in case - to do I needed to measure the bolt circle so the tires fit - thought the easiest way would be to drop the spare that was bolted under the boat - well I couldn't get the 1/2 inch bolts holding the spare on to the trailer loose - tried and tired - just couldn't budge the nuts - ended up having to heat the nuts with a torch - finally got the spare off -

 

So here I'm towing the boat all over the place thinking I'm ok - if I had a flat and needed the spare there was no way that I could have gotten it off the trailer - boy you can't be careful enough -

Good idea to loosen those wheel lugs at least once a year and re-torque them just so you know they'll loosen up when you need them to.

 

Lucky you found out now rather than on the side of the hiway.

They r 175/80 D13.

Max load 1360 lbs.

50psi cold max pressure.

 

Boat is an 850lb aluminum with 300+lb optimax 75hp and way too much fishing stuff according to my wife.

Well that size should do quite fine, maybe just a bad pair. Try for radials next time, D's are bias.

I've been through three sets. Same thing every time. It's weird.
