Saw that JK has new natural donut that is listed as DS* Premium.

 

JKP-D1 _ 0.375"ID x 0.850"OD Natural Donut (pr) * PREMIUM *

 

Anyone know the difference from the DS? (Besides a $1).

 

Mark

Not sure what the diff is but I notice an interesting pricing strategery on the regular non-premium DS donut. It is $3.50 ea. or $46.66 for ten. Now there's a deal for ya.

LOL... I'd bet that gets adjusted soon, now that you've pointed it out, Jim.

Don't know if there is a difference between the "DS" rubber from what Jerry previously sold as natural rubber.

 

I do know that it worked great for my vintage cars, plus was the only donut available anywhere with a large enough OD to use on the old mid-'60s cars.

Fixing the pricing now, oops. There will still be many more mistakes I'm sure. Over 12,000 prices to try to get right.

 

The new premium donuts have a much tighter pore structure, firmer than our regular rubber, excellent grip, and a little longer life. The ISRA guys love them.

Any chance you will sell the premiums as a finished tire in the future?

Tim,

 

If those are the donuts I tested, you need to get these released on rims.

Yes, Tony. I can make them into tires. As you can image, with the huge assortment of tires/rims/sizes we offer it would be too difficult to make all of them.

 

What sizes would you guys like?

I'd go with the Retro sizes – big hub, small hub, and .815" diameter – other classes with smaller diameters can cut them down!!

Plan to come out with small hub (0.400") and 0.765" or smaller diameter. Also medium hub (0.470") and 0.820" or smaller diameters. I should have them available in a week.

 

If anyone has an emergency we could probably make the small hub tires custom for you but would have to charge more since it's not part of our normal production yet.

Tighter pore structure... now that sounds like some of those tires that are unobtanium sometimes and very expensive when you can get 'em.

 

I think I'll hold off my next tire order 'til these are ready.

 

WTG, Tim.

Wow glad I asked. Ten pair of JKP-D1 for $28. A 20% discount. Previously my choice from the track's distributor was very limited in JK donuts. They just carried the D4 for $4.65 a pair.

 

I now have a choice of any of the JK donuts, a discount for buying 10 (which I do anyway), plus there is a new premium fish donut to try.

 

Thanks, Tim.

Is "premium" the same rubber as on the D14 natural?

I wouldn't want the new DS "Retro" tires to start out at .815" diameter, that's way too small to allow any break-in or to do a light touch up on the tire truer. I would highly recommend making them available at .830".

I agree, Jay.

 

The .820"s I have been getting seem to measure  about .830" or just over. That is fine by me. Nothing starting out smaller please.

No, Frank, very different rubber than our D14.

 

Jay, we've got you covered. Thanks for the input.

The .850" OD that is listed for natural on the website is perf. On a large hub they'll be bigger. No prob. I like starting out with .830" finished and ready for practice


You can quote me.

.830" works good for me too. I use them at .820" on my Retro Stockers, then use them at .812" for CA and Coupe. Then at .790" for F1. After that they get used on Flexi cars at .750". After that my cats like to play with them. But they prefer "fish rubber."

Is there a rule of thumb on which id size donut is correct for a given hub size?  Such as:

 

.375" ID tire for .400" and .425" hubs.

.425" ID tire .470", .510", and .600" hubs

 

My local track owners just notified me that they are now listed on the JK website and thanked me for the info. Without Slotblog I would not have found out about JK's new direct to track sales. I want to direct the thanks I received to Cheater for Slotblog and also JK-Tim for using this valuable resource to spread the word.

.690" is way too large for the cars we race on our flat track.  :)
