Thanks! I'm going to mount a few sets this weekend. Also, someone mentioned putting glue on the sidewalls so the tires don't chunk as easily. What kind of glue goes on the sidewalls and how much?

This might not be gospel, but I suggest not gluing the tire sidewall. When you put glue on the sidewall it may resist chunking slightly better (if its done perfectly), but not much, what would be more effective would be to round off the very outside edge of the foam so the rim is the widest part of the tire. Glue on the sidewall also changes the shore rating of the tire unpredictably. If your tires chunk anyway and you can find the piece, PLIOBOND glue which ACE Hardware sometimes carries is a great repair glue, as it dries flexible.

The most proven way to prevent chunking is to turn the tires down, especially front tires, to about 2-3mm of actual foam on the rim, but you will probably chunk tires like the rest of us. Don't resent it, its part of racing 1/12 scale, and even if a tire is chunked it can still be used.

The (super) gluing of the side walls helps stop the side walls 'flexing over' in high grip conditions, rather than stopping tyres chunking mate.

Any news from Black Arts as to when the Mercedes WGT body will be released?

Actually, "seam-gluing" can substantially reduce chunking on softer compounds like yellows. Just a very thin bead of glue at the point where the rim and tire are joined can prevent the tearing of the foam from the edge of the wheel.

Nice one mate, from the guys that run in our national series here in the UK, the idea of running the super around the outside edge stops the tyre deforming whilst cornering. If it helps with stopping the tyres chunking, that's all the better. Cheers mate.

Actually factually, I agree with both of you. But I would NEVER count on gluing sidewalls as a cure-all for tyre chunking. That treatment will also 'help' the tyre chunk more if not done properly and also depends on how objects come in contact with the sidewalls of the tyres. Another big help is to radius the outside edge of the tyre nice and smooth.


But nothing beats error-free driving......., who am I kidding

Not quite... Running superglue on the sidewalls stops the tyre digging in, and is done when the grip comes up to stop the car grabbing in high-speed corners, or grip-rolling. If the sidewalls didn't flex, the tyres would wear oddly, and they don't.

It's not an exclusive UK trick, it came from the States from those running at their big meetings where the grip can be mega! HTH

Exactly, Gluing all the way up the sidewall prevents the tires from digging in and will definitely help prevent traction rolling.

The bead gluing is more of an insurance policy. I don't do it on Pinks or Magentas, because the higher natural rubber content makes the tire more durable. Whites, Yellow and Greys, are more easily "torn" at the factory glue joint, so the "seam glue" technique just shores this area up a little.

JayBee is right, in a perfect world, we wouldn't drive the cars too hard, or hit things. But occasionally you still get spun by a backmarker, so I seam glue just to give me a bit of "cushion"

you shouldn't be so hard on yourself, I don't glue my tires for you.

What's the best way to apply the thinnest possible line of seam glue to the tire?

With a plastic Qtip, but I would have to show it to ya. Kinda hard to give a step by step.

You Tube video!!

First and foremost a quality glue is a must. I've been using thin AKA glue lately. The thin Losi glue is also very good.

Most hobbyshops sell tiny tubing made for applying tiny amounts of CA. It's designed to fit in the end of the bottle. I cut off about 3/4 of an inch at a time at an angle, insert the straight end in the glue, and use the angled end to glue the tire. You just tilt the bottle, and a very small stream of glue will leave the end of the tube. I place the tube in the center of the wall of the rim, then hold the glue steady and rotate the tire. As long as you don't linger too long in one spot, you should end up with a minimal amount of glue on just the edge of the rim and the edge of the tire.

Best explanation I can give without showing you.
