4.60 = 120 ... people put 120 tyres on 2.15 rim every day all over the world
thats why they make 120 dirt bike tyres when just about all real dirt bikes have a 2.15 rear rim...
I have done it for years..

But a tyre around 3.00 /3.25 "90" would be a better fit on a 1.85 rim..
1.60 is the normal size front rim...

tubes... if you are going to run low pressure on the dirt don't go to the
ultra heavy tubes...at low pressre they don't comform to the tyre
as well as a thiner tube... Have you ever seen a ultra heavy tube with
wear/rub marks on it... because the tube is moving around in the tyre
at low pressure....
