When I purchased my 1991 plus 4, I have five Avon ZT-7 tires installed. They have been great with no issues.
HOWEVER, for some reason, the installer used inner tubes. reasoning is unknown. The tires do say tubeless..... Why would they have done this? I did have a flat before shipping it back and the tire shop inquired as to why tubes were used. At the time,I had no answer other than to say it was going on a boat the next day!

I'm asking because I'm going to have the rims resprayed and demount the tires. Should the tubes be reinstalled??

If I go tubeless, has anyone tried the balancing beads?
