Tyres

[Amo911]

During a normal run today, my front tyre came off.

I checked the manual and it stated "cement" to be used when attaching the tyre to the wheel. THis did not come in the kit so I did not use anything.

What should I use if anything?

 Thanks

Cement = Super glue. this will stop the wheel coming of tho is permenant in that to remove the tyre you will need to cut it off.

cheapest way is from the local charity shop - I got 25 for £1 so cannot go wrong there lol.

If you use CA glue you can also buy "un-zipper" stuff that deactivates the Cyanoacrylate so you can actually re-use your wheels when the time comes.

The 'cement' they refer to is, as stated above , super glue which is technically known as cyanoacrylate or 'CA' glue.- Be careful with this stuff, it bonds skin in seconds. Dont buy the Tamiya stuff, its too expensive, but in my experience also dont buy the really cheap stuff which works fine but the tube its in gets stuck real fast and you cant get the stuff out.

As stated above you can get debonders which unstick the super glue.

You will have to use cyanoacrylate/super glue to glue the tyres on.

If you use CA glue you can also buy "un-zipper" stuff that deactivates the Cyanoacrylate so you can actually re-use your wheels when the time comes.

Not worth the time or cost. Debonders are brushed on and work on the glue it touches. If the wheels are valuable it is worth doing, but you have to brush it on, let it work, then peel the tyre back and brush some more on. Takes ages.

Racers use one or two methods, both a lot cheaper than debonder and a lot quicker. The only problem is what the wheels are made from. Wheels made from ABS (like a lot of Tamiya ones) are usually a problem, nylon wheels made by most others work fine.

1. Acetone. First cut the tyres around the tread to remove the inner foam. Put the wheels in a sealed container, pour in some acetone and leave for 24 hours. Come back and the tyres should just peel off. Nail varnish remover can be used if you can't get any acetone. The problem with this method is that some wheels just melt, test before trying by dabbing some acetone inside the wheel, press on it with your finger to see if it leaves a fingerprint.  If it does then the wheel will melt.

2. Boiling water. Boil a pan of water and drop the wheels into it. After a minute or two the tyres can be peeled off, although make sure you let them cool before handling. The problem with this method is that some wheels will deform in the hot water so are no longer round. Unfortunately there isn't any way to test this before you do it.

Adding to the above post, wheels of the following manufacturers are of ABS material:

-Tamiya

-Team Sorex

-Kyosho (R34 style 6 spoke)

-GPM

Speed mind, HPI, Kyosho all offers nylon based wheels, sure they flex a bit more, but they're not as brittle as ABS in the event of crashes.

Though if it's beauty you're after, nothing beats the crisp ABS moulding (as far as casting goes... machining is another different story)..

As an Additional note, those special edition translucent wheels tamiya just did looks neat, but they're not track worthy.
