Boat Trailor Wheel problem?

Question

We recently purchased a used Boat (20 ft Cuddy ) so it is pretty Heavy, It Now has small 15 in Car Tires on it, at 40 PSI they apear to be half flat, It should have a Larger 6 Ply tire, The problem is the 6 ply will rub on the fender,s I need to raise the Trailor, the only way I can think of is to space the Axle from the springs with a 4in Spacer, now were can I find a set of Spacers that are made for this application? unless someone has a Better Idia, Im open for any and all Suggestions.

A Personal Message to all of you, you dont now How much I appreaciate each and every one of you that take the time to answer our question,s no matter how stupid they may be

Thank You

Answer 1

might have the wrong size boat trailor

Answer 2

you may have the wrong trailer for that size boat. A really heavy boat should have a double axel trailer.

Another thing is that trailers are not supposed to have automobile tires on them. There are tires specially made for traillers and they are marked as such right on thier sidewalls.

As far as putting spacers on axels is concerned I think any sort of homemade modification is going into dangerous territory.You have to be able to control that trailer while going down a public roadway and not put any lives in danger.

Answer 3

The ply rating shouldn't increase the tire size> Go to a 6 ply same size tire>But if the tires are rubbing go to the next size springs> Raise the fenders>

Answer 4

Wal Mart has great prices on tires with wheels. Find out the weight of your boat, trailer and gear. See if a 14" wheel and tire will do the job.

If not it sounds like you have the wrong trailer for that boat. Like the others said, the trailer should be able to accommodate large 15" tires or be a double axle trailer. Having to modify the trailer to accommodate the Right tires just means that the trailer is not strong enough for your boat.

Answer 5

Would it be easier to raise the fenders?

Answer 6

How are the springs? If they are getting rusty to the point where they will need to be changed in a year or two you may consider just changing them out with ones with a higher arc. Are they under or over the axle? If they are under you may can take them off and put them over the axle. To just move the finders up would be OK if they will not hit the boat when you load it.

Answer 7

Trailor and tyres are fine just put a big wall tyer. bigger profile and wider tyre. or you can put a extra leaf in ur springs. or get a angle grinder cut the fender off and reweld it hight or leave it off. hope this helps.

Answer 8

i had a recent problem very similar to yours. i put a shim under the axil and i still had the same problem. i ended up replacing the leaf springs with a more heavier duty one. one that had more leafs in it . this cured my problem. it sounds like your problem is because your leaf springs lost there spring (if you know what i mean). you might also have to replace your tires and rims with a trailer tire. my trailer tires have a c rating on them and require 70 p.s.i. you could call a trailer manufacturer and they could also give you some good advice.

Answer 9

This is an issue that you need to have an experienced  marine trailer mechanic take a look at.  The 15" rims are common on trailers.  The tires, are different.  Trailer tires are so marked, and have several load limits.  Ofter the correct air pressure is 60 lbs.  not 40.   So, before you panic, read all of that small print on the sidewall.  It may be that to save money, someone put the wrong tires on the trailer.   I know that at the marine shops I worked at, we were careful to check the trailers that were sold with every boat, including the tire ratings.   We wouldn't let an unsafe trailer out the door.
