Default Any easy DIY way to shave foam tires . . .

Any easy DIY way to shave foam tires . . . I don't have a drill press or anything like that.

I was wondering if I could shave them down on the car somehow. Mainly the rears . . .

Any ideas?

I wouldn't use anything other that a tire truer. Does your track have one? If not, somebody you race with must have one?

Yeah, the "super gurus" have them . . . rarely bring them . . . there are so many people pestering them I feel like el numero uno noobo asking them to shave my tires.

I guess I should stock up on tires when I eventually do ask them . . .

I'm pretty sure you must set the car up with the batteries in. I can't see how you could without?

I used to just disconnect the motor (remove pinion) from the drives and then take my dremel with a sanding drum and sand my tires. I mostly did this with my rubber tires to scuff a new set.

If you have the drum spin in line with the tire it will rev up the tire. Then turn the drum a few degrees to grind on the tire. Too much off an angle the tire looses speed and you can flat spot parts of the tire.

Yes there is.........
You need a drill....... cordless or corded, it doesn't matter.
A G Clamp (C Clamp)
A Hacksaw with blade.
A bolt and nut's (2 pref') to fit the tire onto.

Use the clamp to clamp the Hacksaw to a table or other sturdy bench or something.
Take the bolt and place in the drill with the threads outward and place one nut on fairly well down the thread, then the tire your going to true, then place the second nut on and tighten down onto the tire.

Start the drill up at a fast speed and "shave" your tires against the Hacksay blade you have clamped down.

This does work as I did it for a couple of months while racing on a very tight budget!!? There is a certain amount, quite a bit actually, of skill involved to keep the tire cut square. Don't forget to round off the edges of the tire too!

Also keep a close eye on how much your taking off too. You need to have someway of measureing the tire diameter. I used to use a plastic pipe I had found that was 60mm ID (Internal Diameter) Then cut (shave) the tire untill it just slips into the pipe. Then you'll have all your tires the same diameter.

Hope this helps you out.

British Menace

This is not easy so you really should try and find a truer, maybe off Ebay or something? Be careful using this method! No tire is worth hurting yourself over!!!!!

I tried the drill press, bolt, and hack saw blade approach. It got the job done, but the amount of time it took and the amount of nasty fumes I inhaled convinced me to spend the $200 on a truer. Then Prisms came out, and they don't need truing.
