I recently converted my from tire to a 21" rim with a metzler 120 70 21 and the rear with a 170 60 17 metzler.

To anyone who has the same setup, what tire pressure do you keep your tires?

 

Here yah go:

ME880
--------------Solo------2 Up Light--------2 Up Heavy
Front-------38-40--------40-42-------------40-42
Rear--------44-46--------46-48-------------48-50

 

I don't know about the 21", but I run the 19" up front with 40PSI and the 16" out back with 46PSI.

 

Thanks for the reply guys!

 

Run exact same tires and sizes
IMO I like to run 40-42 front and 44-45 back.
