Tiny's were also available from distributors but I do not believe that they made it to the East Coast that much. Baldwin Specialties was one of the distributors that carried them.

Tony,

I don't know. Your experience in this hobby is a ton deeper than mine. It would be interesting to find out. I have a light green pair and a light blue pair that are almost NOS. I got them from a (now deceased) friend of mine about 1999. I have them stored in (hopefully) air tight plastic 35mm film containers.

Back in the day, we would soak them in genuine oil of wintergreen to soften them up. Our local track was in a shopping mall and there was a drug store next door. That was convenient! I tried to find some a few years ago and the best I could come up with was synthetic.

Someone here on Slotblog recommended getting the Walmart equivalent of Ben-gay, so I did that and it seemed ok. I did put a bottle of it in my slot box to bring back the smell from the day. Young people today think because I'm an old man, that I keep Ben-gay in my slot box. They don't realize every kid's box back then smelled of wintergreen. :laugh2:

oh yeah! thats my favorite smell! not old people but wintergreen slot boxes lol.

John,
The first slot car tires were made of molded natural black rubber pretty much everywhere, the first of course made in England where the hobby was born as a going concern. By 1963, some racers in the USA had discovered molded sponge rubber, namely model-airplane tires made by Graupner in Germany, and called "Rekord Elastik". These were ground to slot car sizes and because of their circular section, early aftermarket rims often had a half-circle inner rim to accommodate them. By 1964, several SoCal racers had discovered Rubatex, a company distributing neoprene sponge sheets located in Santa Fe Springs. These rubber sheets were available in various colors and thicknesses and were used in industrial or consumer oriented application. Rubatex seized the opportunity and had tooling made to die cut donuts from the 1-1/4" thick rubber sheets. Tiny's became one of their customers but the largest was Classic that in 1966, really started the ball rolling in a huge scale. Riggen got in the game and also became one of the big players until the hobby collapsed in 1968. Then it became the territory of smaller surviving companies such as Associated, Riggen, Cobra, Champion...

Meanwhile by 1966 in the Midwest and in Michigan and other places, silicone tires on dry, slick tracks had become the thing to use.
In 1966, MPC of Mount Clemens, MI, was first to introduce silicone coated sponge tires at the commercial level, but this had been inspired by their use by racers on local tracks. The smart guys had figured that rolling trued, soft sponge tires over black or white silicone weatherproofing material laid on a flat surface, then letting them dry, gave them a tremendous performance advantage over the hard molded silicone tires mostly manufactured by Twinn-K.

I am not aware of use of silicone tires on HO cars until at least 1968, but it is possible that it happened before. I seem to remember that both Champion and Twinn-K began offering silicone tires for HO cars sometimes in 1969, I have to verify this.

Have no data to back my suspicions (since my focus at that time was 1/32nd) but MPC may have co-opted the coated sponge tire concept from Bob Smolinski of White Circle Tires , who I got to know during the early days of R/C racing , Bob's process was to rack the ground tires on long spindles that were ganged and geared together and dip the tires by bringing a tray up from below with a diluted silicone solution - not sure of the formula but the smell was certainly powerful.

I worked for Bob at White Circle for a short time when he rented space at Shore's Raceway in Saint Clair Shores Michigan. The tires were mounted on 1/24 axels that were rotated by 64 pitch Welden spur gears that were mounted between two pieces of 1/8 by one inch aluminum flat stock. Each rack had about twenty four pair capacity. They would rotate at about 15 rpm. He used Dow Corning White bathtub caulk. I think that he used Xylene to thin it. The pan was about one inch deep, and you would hold it under one side for about two rpm's and then do the other side. I think it would take about three or four coats. I also worked for Shores Raceway. To sell the tires, we would hold the tire against the vertical glass on a showcase an let go of it and it would roll down the glass until it reached the floor.

Bob, thanks for that inside info. This is the kind of thing I was hoping for when I started this history thing. I think it is important to hear from the people that were actually " there ". P, was the Baldwin you mentioned here on L.I.? Did it have anything to do with Bert Lemil or Lemil distributing? He was located in Baldwin as well.

I forgot to mention in my first post that I think White Circle was the originator of coated tires. One of the racers at Shores Raceway ( Dave Lowe ) was a I think a production manager at MPC. I don't know it they worked with White Circle or just made their own, but Bob was first as I remember. White Circle also used a clear coating to please the racers that didn't like white rear tires, but they did not come close to the traction of the white one's. Bob

Some of you may know this and some may not......Bob Smolinski was granted a U.S. Patent for silicone coating tires. I have a paper copy of this Patent.

You may also find it online. :)

I also believe that Bob Haines REH Dist purchased all of the White Circle coating equipment and fixtures a few years back.

That's settles it. "Smolensky" is how I read it in an old mag race report.

No, different company, different people, different wheels. But the rubber came from the same place, Rubatex.

If I remember right from my days in the Midwest during the 60's and 70's, some local guys made tires for the local raceways with Dow Corning and benzene. Glad I never tried it myself! The White Circle tires dominated many of the Midwest tracks that did not allow glue. We used to put down 6 inch water trails on the main straight with a drop of soap to clean them off every lap. It worked real well.

Tiny's made their way to Western New York pretty quickly. My memory may be a little foggy but I recall the red variety becoming the must have on local tracks. Then threaded axles went away and the blue and grey taper lock hubs came into use. I also seem to remember running on a track prepped with castor oil.
