THE PORTAL HUB - Pinzgauers, Haflingers, Volvo 303s and more!

I put tubes in mine because I had two small rim leaks running the tyres tubeless and got tired of looking for the compressor every 100 miles or after just setting for a few days.
I did not think about the friction aspect, course I don't think I go that fast. I imagine that running at 70+ mph might cause some friction, that's not my issue.

I took the tubes out with the malyoas and run with out them on my TSL's, only lost a bead once at a very steep angle with about 12 passengers on board, didnt have a can or lighter fluid to re seat it so had to swap it with the spare.
