Check the JDS 7017 8 hole rear tires.
10.30 X 285 3/32 axle

Use the part number to order from your local track.

Re: aa/fc tires

isn't .285 too small for aa/fc, i know jds makes that same tire in a .435 wide but isn't it still natural rubber? i am talking about a aa/fc using a open  64 .459 arm motor.

Re: aa/fc tires

Joe,

Natural rubber goes by a bunch of different names like Tuna, or Pirhanna. SBR is a a blend of natural and synthetic components. You won't want any tires smaller than .400 wide for a AA/FC, and depending on the motor you may need even more than that.

Tuna tires don't work on a AA/FC because they are too soft. The preferred range of hardness for SBR tires on AA is 22-25. Once they get down to 18, they start running slower. It only takes a few good runs to get there too. Don't even think about it if the car spins on the run. That's a tough pill to swallow when they cost 20 bucks a set.

Yellow Dot is an SBR rubber that was made by Rubatex, no longer in business.  Some have a stash hoarded, but who knows how long it will last.

Re: aa/fc tires

If they are SBR, then they would be worth a try.

Yes, you understand correctly. If they work ok, and after 3 or 4 runs the car slows down, put another set on to see if it comes back. Most of the time, enough glue is down to prevent any serious spinning, but if it does spin, it breaks down the rubber much faster and softens the tire, making it junk. I learned this by trial and error. 

One tip: If your car slingshots through the shotdown area, it's spinning on the top end. AA/FC's are light enopugh that they should stop reasonably well, but if it's spinning it's brains out at the finish line, the glue in the shutdown grips the tire and sends it into the sheets.

Re: aa/fc tires

i might order a set and see.  btw why is it that soft rubber doesn't work, does it grow/distort too much? thanks for the info...i'm in the process of building several cars and i'm in new territory with all this and want to somewhat know whats going on before i just break everything. lol

Re: aa/fc tires

Tuna tires are much softer than SBR, and SBR has its lower limit,  so that pretty much rules them out. I think they distort too much at speed. The edges grow more than the rest, so it doesnt maintain a flat surface on the track which reduces traction.
