Location: Fairfield, IA | ShoreLand'r trailer, single axle, ST185 80R13 tires. I have less than 3,000 miles on the trailer and am getting really heavy wear on the inside of both tires. The right side is worse than the left.
I checked and nothing is hanging down and rubbing on the tire.
The first year I had the trailer I cut a corner short and hit a curb hard, going up over the curb. There is a slight indentation mark on the wheel but the tire never lost pressure.
I did take the tire/wheel off the axle including the bearings and then reassembled everything.
The only two things I can imagine causing the problem is the castle nut on the axle is not tight enough, allowing the tire to 'wobble' OR the axle is bent up slightly forcing the bottom of the tire out, causing the inside wear.
When towing, in the side view mirrors, it does not look like there is any side to side movement and the tires appear to be running level on the tread and not canted to one side or the other.
Any ideas?
Dave. |

Location: Elk River, Minnesota | Hiya,
Chances are you have an axle that is not in perfect allignment. I had a shoreland'r that had the same issues where the tires were wearing on the inside portion. To alleviate this issue, find a good welding shop or somewhere that works on axles and they will straighten it. Amazingly enough, it does not take much to have the axle not quite in allignment where the axle shafts are welded to the the main axle frame.
Not sure of cost, but not a hard thing to fix.

Location: Elko - Lake Vermilion | I think Steve has it right, your axel is bent/or out of allignment.
Also make sure your tires have enough air in them.

Location: Stevens Point, WI | The other thing that could be causing this is if your boat is on the trailer cockeyed. It can make a big difference if the boat is just a little off center. Also, how is your weight distribution in the boat? If it's heavier on the right side, and then the boat is off center on the trailer just a little, that can cause more wear believe it or not. |

Location: Oconto Falls, WI | The joys of a Shoreland’r! I have one as well and have the same issue. Getting the axle trued up will work, for a time, but it will go back to wearing badly on the inside. I had it done by a welding place that also makes trailers, and they put it up on a rack to get the trailer “trued”. The only thing I have found is to rotate the tires from side to side throughout the year, as well as getting the tire flipped on the rim itself. It is a bummer when you have to get new tires because you have cords showing on the inside/outside (if flipped enough), but the middles look as if they are new. I think I m on my fourth set of tires now in 9 years! |

Location: Fairfield, IA | Boat is always centered. It is light enough that I can move it side to side to center it. The boat and motor is +/- 1,200 lbs. I have the glide pads on the bunks so it is easy to move.
I am heading out to the garage now to pull of both tires, flip on the rims and have re-balanced. Not certain how someone would 'true' up the axles as I imagine when they are welded on they are in a fixture that 'should' be perpendicular to the center line and to the ground. Not certain how a weld shop could do this without fixturing.
I just hate to think of the p.i.t.a this is going to be going forward.
Dave.

Location: Stones throw away...finally!! | I had my axles trued on my tandem as I was experiencing the same thing. It is more or less a heat and bend procedure if it is a solid axle. A shop that knows what they are doing can true it quite simply and relatively inexpesively, compared to new tires every 300 miles. |
