But from hauling our Sandpiper to all the Rendezvous and we have mid size trailer tires with tubes inside then, I am surprised how Warm they become when towing. Tire pressure is correct but when the boat is full of gear there is some extra weight. At all stops or breaks that we take when towing to/from a rendezvous we immediately as a precaution touch the hubs and tires to detect any abnormal high heat. Smaller sized tires would even heat up more.
NEVER RUN RADIAL TIRES WITH INNER-TUBES!!!!!
It causes the tires to overheat which can result in blowout's.
Please don't tell me you are using bias-ply tires on your trailer?
That technology died in the 60's.
Omg you can't turn your back.
