tire size for 16' johnboat trailer

[Justaguy442]

I had 12's x 4 bolt on my 14' tin and i upgraded to 13 x 5 bolt. Alot bigger and wider which i believe will work better on gravel roads.


I dont buy the car tire excuse on light boats. If they are both radial tires then the side walls are thin on both, unlike a bias. On heavier boats id say go with trailer tires for sure. But on a 1000 lbs boat i doubt youd notice a difference.

So i was doing some research into the car tire vs Trailer Tire and they talked about trailer sway. My nephew has a 14' tin on a trailer with car tires and my brother mentioned it sways but they figure its because the tongue is longer then usual. So after reading this i will change my opinion and say that just use trailer tires. A swaying boat is not fun at 60 mph.
