Default Tire truing

I just cut down a set of foams without a truer. Is it a bad idea to repeat in the future? I just attatched the wheels to a drill and ran it on a sheet of sandpaper.

I think it worked pretty well. I cut it from 66 or 65 to 63mm. I don't get what you mean by how I can be sure the tires are perfectly round. They should be round because the tire is spinning on the drill and I put the tire against the sandpaper.

If you pushed harder with the sandpaper in one spot than another it could create a flat spot. In offroad we just use a pair of scissors or a dremel to trim the foam, but I guess offroad isn't nearly as precise as onroad.

Had already thought of that. I had the sandpaper sheet taped to a piece of flat wood.

I used to use my drill press to true tires. It actually worked quite well. Just fixed a sanding drum to the table and used the up and down motion of the arbor to keep it true.

I used to do the same method when I was racing 1/8 onroad. Drill press plus a vice that had y and x axis movement (I think that's what it's call) with sandpaper glue on a 1/2" block of wood.

What the guy meant by round was if the axis of rotation of the drill is not perfectly paralell to the plane of the sandpaper you could end up with a cone shaped tire < . which is counterproductive as one of the purposes of truing tires is to remove any "coning" Although if you are running foams as big as 63 mm I suppose what little bit of coning you induced wouldn't matter to you.

I'm not even close to serious racing yet. So... yea. I think it gets rid of coning pretty well. When I do get into serious racing, I'm gonna get a truer.

so you are positive you had the drill completely parallel to the sand paper?

Don't post a thread on why your car has no traction around corners.

local shops, tracks true tires for like 5 bucks..

As another person said. A few small imperfections wouldnt matter if my tires are like 63mm.
