Default Foams are separating from the wheel...can I use CA?

Can I use a tad bit of CA to glue the foam tire back on the wheel? It is just the outer part of the foam that is coming separated.

you can try the thin stuff but not sure how it will affect the foam as it soaks it up, it could create a hard spot on the tire...

It's better to use either thick CA or, better, to use a good quality contact cement - apply to both surfaces, let dry a bit and then stick together (just like the directions say)

The funny thing is that the only two foams that are coming separated are the two rears. The one rear tire started to chunk the last time I ran the car. It was probably due to the tire coming separated from the wheel. Is there any way I can prevent this from happening again in the future?

I don't want to replace just the rears either because race day is tomorrow and that will throw my whole setup off. It seems that everything bad happens to me the day before race day!

Just glue them back and you should be fine.

Remember that we tend to wear the rears faster than the fronts so they're taking a lot of side forces. They will want to peel just a bit, so check on them every race.

It's worse with 1/10th pan car - just think, you're using 45/40 shore tires, we're using 28. . .

Try slow CA glue. Hobby Town sells it. It's called "Slow Jet." It's described as extra thick CA glue. A friend showed me how to mount foams using this, it's sticks very well.

If you tires are seperating in the rear. You need to change your setup to be a little softer in the rear. Your asking to much of your tires for rear side traction. Your goal when setting up the car is even wear across all tires and as little wear as possible. If you tires burn up quick your setup is to stiff.. it may feel great but you are putting to much emphasis on the tires to perform. So as the race goes on and compounds break down your reaction changes.

After every race I always check each tire and reglue any seperation that may be forming. I prefer a beed of glue around the edges of the foam to help prevent traction roll.

Much of this depends on driving style. I tend to pitch my car around corners and this places a lot of wear on the rears so they develop more "pull away" than do my fronts. I'm faster driving this way than I am with a balanced setup.

Just the nature of the beasts, slightly "loose" in the rear is faster. No controversy in this. But it does mean that the rears are GOING to wear just a touch faster. The rear end has to do a lot of work to stay behind the front. . .

Separations are normal for foams. I haven't yet had a set (nitro or Pan) that I don't have to tend to. Rears more than fronts, usually.

I've only had one or two TIRES that have seperated. Probably because i don't pitch my car in corners...faster that way.... Just get some thick CA when you get to the track and let the tires drive for a while. Another note...is there a reason that you are running Speedmind foam tires? The new TRC's definitely hook up, as do Jacos.

so do the speedminds (I have been told that the UFRAs are based on Speedmind)

There isn't a single brand of good tires.

Also - pitching the car can be far faster than just driving it around the corner . . . watch the 1/8th scales (yeah, they're different cars, but just look at them). I've timed myself and I am definitely faster, by like a second a lap. . .

Also, look at tire wear. It says something when you put a lot of wear on the tire, it says you're working the tire. If you don't put a lot of stress on the tire then you're not at the limit and not going as fast as you could be.

I guess you dindn't see Days of Thuhder...

Remember that part where he says give me 10 laps your way and 10 laps mine.. Then he came off the track the second way a faster and less tire wear


hehe

Yep, I did see it. Great flick! (Although it really is only Top Gun on four wheels. . .)

It's also a different type of racing. . . they don't use four-wheel-drive, one-way fronts or solid rears, nor do they use foam rubber tires, etc etc etc.

I'm not talking about an unnatural amount of wear. I'm talking about what is fairly normal.

Remember, also, that Nascar tires run for about 50-80 miles TOTAL and then they're done, forever. That's a LOT faster wear(proportionally) than we do, even at our worst.
