how fast can a trailer with small tires go
The smaller the tire the faster it has to turn to keep up with your tow vehicle. Thus the faster it heats up and more turns on the bearing (laugh, but it all adds up) The smallest tire I have is a 14 inch dia on my 11 whaler trailer, it only gets towed a short distance and no more than 50 mph. Nothing ruins a boat trip more than problems on the road with the trailer or a traffic ticket....
