There is no need to glue the tires to the hubs. I put about 200 landings on a set of 2.5" wheels on a paved runway. Needless to say, the tires were worn out when I replaced them and they were still quite difficult to remove from the rims. I have always used the Trim brake valve as well....I HIGHLY RECCOMNEND IT!! The Trim valve is the best kept secret in modeling.........

When I assemble the brakes, I smear a light coat of lithium grease on the O-ring and bushing. This keeps the brakes operating smoothly. I just serviced the brakes on my A-7 after 30 flights since the last cleaning and everything looks good....'Could have gone to 50 flights....................
