I've had success with the small pore natural tires (JK Premium, Kelly Retros, Alpha Primo).

 

Are there other manufacturers selling donuts or tires with a similar rubber?

I tried so hard to get BSP rubber, What i found out is they only sell them at .790 donuts now, to small for retro.

Maybe you will have better luck than i lol.

I believe JK is out of premium donuts in retro sizes, but I might be wrong on that. Im starting to feel boxed in on buying Kelly Retros since they work so well on the FL tracks. I wish they sold donuts to help keep costs down.

You could treat your own rubber.

A few racers do it to keep their cost of tires down.
Test, test, test and go test some more.
You're never fast enough!!! 💯

Luck is the residue of design.

Id need a tutorial for treating tires to firm them up. I believe someone posted on here that the chemicals used are quite dangerous.

Bucky- at $12-18 a pair, adjusted for inflation is about $2.50 in 1960s dollars. Not too bad.

If you want to do your own its
1. Source rubber
2. Cut rubber
3. Treat rubber with known carcinogens
4. Mount rubber
5. Match quality of existing suppliers

If you can do all that on your first try then thats amazing

Otherwise, one needs to spend the time and $ which requires becoming a supplier just to get your original investment back.

By ending your post with your call it comes across as an attack on me.

I dont want to manufacture tires or source rubber. Im looking for existing companies that already do this. However, I also like to save money by mounting my own donuts when I have the time.

Sorry Bucky. Not everyone gets my humor. Ive been down the rabbit hole of rubber. Ive bought sheets. Ive bloodied fingers figuring out how to cut it. Ive mounted tires perfectly only to realize later that the glue was out of date and thus separated during an event. Ive had firm rubber turn soft days after mounting.

I have different sources now for special rubber. Others who have already blazed the trail.

I was hoping to save you $ and aggravation.

Sorry if you felt like my comment was an attack.

Frustrated racers tend to leave the hobby. Id rather that you stay and enjoy the fun

I'm overly sensitive to perceived internet slights. Have a good one.
