Yes I bought my blaster with 22-12-8 in the rear and hated them"Too Big"
BTW I heard tires that big are clutch killers...But correct me if im wrong
The first thing I did to my blaster was remove those beastly tires and went with 18-10-8 and couldn'I:It be any happier.
I would pass IMO on the 22 on your blaster
