I use to on some old leaky cast aluminum wheels , I wouldn't do that now due to the extra weight: down: Make sure if you do use tubes that you are using the correct tube type for that tire, bias tube for bias ply tires, radial tubes for radial tires
I'm using them on my early skinny Ansen wheels that didn't come with the inner safety bead hump that any modern wheel was made with. I was concerned of mass inflation loss after a wheelie or abrupt turns under power. There are a few choices out there. If I can dig up my receipt I will post the vender name here. Merry Christmas All!! Bill
Had tubes in the fronts on my Super Tricks - car came that way. I didn't run then with the Flys, though. The extra weight wasn't an issue - the car ran downtrack on its rear bumper for 300 feet before it got wheelie bars.
What size and type (bias or radials?) front tires are you using, Cesar? If bias and those tubes are for the original bias ply V.W. bug cars your good, if they are for radials and your tires are radials your good Don't run bias type tubes in radials type tires
