Just wondering if anyone can advise on what rear tyres are best recommended for GT12.

I have read recently that natural rubber is the go, but what is classed as natural rubber these days?

Many thanks.

JK untreated, are the best in my opinion.

jk untreat or treated are my first two choices. If you need a little more bite try the Koford fish rubber, very sticky and long wearing.

Colin,

Have you tried B.S.P. rubber from Brian Saunders in the U.K. Very good rubber with good wear rate.

I've been running JK8713E's and JK8703E's-- this is natural rubber on magnesium hubs. The plastic hubs work too, but I think I get a little more bite with the Magnesium hubs!!

Thanks guys for the help.

What is the difference between treated and untreated rubber? Does the treated give more or less bite, or do they wear differently?

Tim, many thanks for the part nos. In what situation would you use the big or the small hubs?

Rod, sorry haven't tried the Brian Saunders rears. Not seen any down here in OZ, our tyre choices are a bit limited. Did however recently try one of his Euro12 chassis, very interesting movements and quite different to the Slick7 designs.

Thanks again,
Col.

Hi Col!

The treated tires, JK, are harder and have less bite. If I find my car tipping out of the slot in the corners, too much bite, I change to the treated type tires.

If I remember correctly the bigger hub also gives less bite. But that said others, Lee Gilbert in particular, say bigger rims means more bite. Only you testing on your track will tell for your setup...

HTH...

See ya!!

Hi Colin

I use, as others up here in NORCAL/SCRA. Alpha soft do-nuts on Lee Gilbert's wheels (small hubs) there's been maybe once or twice I have used his big hub. Yes, I glue and true my own tires. It work's for me, if my ride has to much bite. I adjust this problem with the body.

Regards Colin,

Dave

Hi Joe, great help. Need all the help I can get! Yes, I read what Lee G said about the large hubs as well. I kind of remember reading "larger is less" some time ago when the big-hub tunas first came out. Ah well, more testing.....

Dave, is the soft Alpha you use the "piranah" rubber? Do you find this runs down pretty quickly on the GT12s?

Thanks again,
Col.

Hi Colin

You bet they do Colin, just like a ice cream on a hot summer day At the price that one pay's for Do-Nuts($2.50) it's not a big deal to me! I'll go through 3-5 prs. On a race day, this is with pratice on three cars. Yes, I have the time of glueing and trueing involved. This is just another part of the sport/hobby that is something that I like to do. At $11.00 - $15.00 a pr. the cost of tires gets to be a key folcul pont in one eye's. Especially if you are buying them yourself over the counter, 5prs. at let's say $12.50 is $70.00 smackers. The do it yourself route is 5prs. at let's say $2.75 (factoring in the glue & thinner) is $13.75smackers

Yes, you will have to buy a tire truer to do this ($169.00 for a Hudy) Most guys that I know re-true over the counter tires any way this must tell you something. I have re-tured over the counter tires and they are WAY OUT I have no idea what level you race these things (GT-12) you will use tires up at a alarming rate, more so then the bodies that these car's love too eat up I perfer the glue/true my own for many reasons, one of them is the cost. I'm sure one can do the math, and see this is a by far a way more economical way to go. Unless you have nothing but $$$ or you get FREE tires, or just plain LAZY. Which I'm NOT saying you are!

[slotcarcol]

Dave, many thanks.

Yes found the Piranah rubber wore down pretty fast, and summer is hot for ice cream here at the moment!

Tyre cost sure can be a focal point, especially with the large selection of rubber/hub combinations out there to try and test. The donut route sounds like an economical alternative to look into, thanks.

Best Regards,
Col.

Hi Colin, you are welcome

You bet truing and gluing your own "treads" is something that one can do once they know how once one has mastered this, they can spend their $$$ on other aspects of the sport/hobby THAT WILL STILL BE SUPPORTING THE INDUSTRY that support's our sport/hobby

Colin, if you are after donuts the best selection is available across the ditch.

You won't find a better selection anywhere.
