Changing tyres

[Benjy1]

I would like to change my tyres without buying new inserts and wheels every time. Of course they are super glued and that's where the problem is. What do you guys do?

I soak the whole wheel, tyre and insert in acetone. This dissolves the glue and I re use the wheel and insert.

Cool another question to this I drive indoors on carpet using yellow mini pins have you heard of using 2wd tyres on 4wd car at the front? What difference does it make?

Yes I have heard of this being done.
The best thing to do is try it, you might like it, you might not like it.
I dont think there will be much of a difference on the mini pin tyre. I think there is more of a difference if you tried the mini spike.

i find if you cut the main of the tyre off, remove the isnert you can get more wheels in your bucket and no inserts to dry!

Yes Mark, this does work better, but, and it's a big BUTT haha, I said butt, ok what was I saying, oh yes, it takes far more effort to do it that way! So I just dunk the whole wheel tyre and insert in, the foams are fine with a good rinsing.

rough up the mating surfaces (wheel and tire) with some sand paper.
Put a bead of hot melt glue around the wheel and let cool (without fitting tire)
When cool, fit tire and pop in oven at approx 100c for 6 mins.
Hot glue melts and tire beds into place.

when tires are knackered just put back in oven and then you can pull the tire off.

down side is if missus catches you putting things like that in the oven.

works for me.

(ovens vary. hot glue can be hurty. be careful)
edit. some Tamiya wheels will melt

heat from over will temper the tires mate not a good idea,stick to simple super glue theres a reason everyone does it that way,90% most of us dont have a oven track side

I am sure you are right. I don't dispute it. Try roasting an old tire at 100c for an hour and see if you can tell the difference. I cant. Green will still be green etc.

It maybe a good method for those that dont have well ventilated places to play with acetone or have kids that could get their mitts on it.

no it wont rubber changes it properties at that sort of temp.

If they are made from just natural rubber temperatures up to 100c should be ok.
Do you know what type of rubber tires are made out of?

I tried all methods on Saturday in race prep for today.

Decided that baked was poo and boiling hurt and was poo so acetone is the future! .

I will only be removing tyres from rims when bald (worn tyres can be used for the skate park ) so I will cut the tyre off and soak.

Cant see the need to save the tyres TBH with rims so cheap...

I don't use superglue,I use clear silicone sealant to fix tyres to rims.

They don't pull off on the car but will pull off at tyre change time with
a bit of effort(read:grunting and swearing).
The dried sealant is easy to pull off the rims ready for some nice new rubber.

do you have to key up the rims with sand paper for silicon to work?

I don't do the oven bit on prepping but I do 'oven' them to remove the tyre.

This time I got it wrong though. Had a blonde moment. 200c for 20mins for some reason, instead of 150c and 10mins Just glad the smoke alarm didn't go off in the works mess room . Two extractor fans on, door open, window open etc

Looks like the tyres & inserts are OK though

I know that now. Mine are very tacky so should be good for grip. When they came out of the oven I got little black pin heads all over my fingers

isnt it better for the wheels/tyres to be supported above the acetone in an enclosed container?? put them in, leave them in overnight and the fumes do the business..

I used to race heavily with Slot Cars, and the practice was there to glue the tires to the hubs, and as you can imagine the rate of wear was massive, so we were changing them all the time especially after truing them as well.

Of course most the competition hubs were alloy of some kind, and some people did use super glue, but there was another type of glue which contained rubber which wasn't as brittle as super glue so would flex better with the tyre and hub - it was also quite easy with a sharp knife to remove the tyre from the hub when finished.

Can't for the life of me remember the name, it was black and when dried stuck like shit to a shovel

I think this is the stuff your thinking about
