Hi, new member

There isnt to much info here for the 2009 and up harley ultras as , Im running a 09 ultra , 107 stg 4 ultra, I am contemplating on using a CT and probably will. Those 180/65/16 dunlaps get pricey. It is a 5 in rim. Thinking about asking members here about a lower profile CT 50 vs 65, i already run a 30 tooth pulley down 2 from stock. and have 121 trq at 3200 rpms, Maybe it will be to much?? i dont know how many rpm's it will raise from what I have now. I run 2750 rpm at 70 in 6th which really,really great for passing with no down shifing even with 2 up. But how much is the question??? Thanks
Tim

Welcome
If you go with a 195/60/16 it will be almost identical in height to your stock 180/65/16.
It is about a 1/2 inch wider too. Which I'm pretty sure on an 09 will fit.
A 55 series tire will be about 3/4 of an inch shorter which will make your gear ratio about 4% lower and make your speedometer run about 2.5mph higher than actual at 60mph.
