I own this trailer

600 Lb. Capacity Boat Trailer & Other Small Boat Trailers

I want to make something like this Using used atv tires

Jet Ski (PWC) Dolly 12- from Wheeleez, Inc.


Basically using a standard trailer to beach launch a boat by hand. Has anyone mounted atv tires on a trailer?

 

We do it all the time on our fishing trips. We can only truck in so far before the trail in to narrow and rough, these lakes are mostly air access fly in lakes.
We have ATV trailers for camping gear with ATV tires on them full time.
We have one boat trailer that has trailer wheels for the highway then we switch the tires to ATV wheels when pulling with a ATV for a smoother ride.
The trailer could make it with trailer tires but the ride is much more bouncy for sure and its a rough 20 mile ride.

For lakes that are not as far or as rough to get to we just leave the trailer wheels on.

Here is a pic of us heading out, not a great shot but every ATV is towing a trailer with ATV tire on them.

 

Nice to see it can be done. Now I'm just trying to figure out the technical side of things. The bolt pattern on the trailer wheels has a diagonal measurement of 4 inches. That is 102 mm, most atv tires I see are 100mm or 110mm, none of them are measured in inches I assume it needs to be exact unless I use a smaller diameter bolt it might get me some wiggle room of a mm or two to get them mounted and just really crank them down. Im not going to be towing the trailer anyway so as long as the wheels turn I'll be happy. Can anyone help me out with figuring this out?

 

We just bought some cheap used ATV rims that work on 4/4 trailer hubs.
As far as we found, only Kawasaki and Polaris made 4/4 atv rims. ATV Tire and Wheel Application Chart : ATV Tires Free Shipping : ATV Wheels : Mud-Throwers.com.
