metric tubeless on Comstar in inches
« on: January 13, 2020, 01:21:28 pm »
Hello
on my 1978 Hondina I have to change tires.
I found on the market a 110/90/19 front and a 130/90/17 rear.
The question is, can I avoid putting the inner tubes and using these tubeless tires on comstar wheels?

I use the Comstars with tubeless 100/90-19 and 130/90-17 on my ToMatic, without any problems.

Well Jukku
I was what I wanted to know, my trusted tire dealer has no experience on these Comstars and I preferred to ask you more experts.
Do you know if there are problems with the assembly of automotive valves?
Thanks to those who express themselves through their experiences.

I’ve used tubeless tires on Comstars and my Lester wheels too. For valve stems I used a competition style bolt-in unit. They are externally threaded, use a rubber gasket top and bottom, and fastened with a top nut. From memory, I may have had to open up the hole size a bit, but they worked really well.

I use bolt-in 90 degrees valves on the rear wheel because it is easier to check the pressure.
