Our System and Process
Our process  (PrestoryWay out?The solutionOur processCareSpecial wishes,?  Legitimacy)
 Many vintage cars needed them like the pot needs the lid: White or red rings, sometimes discreet thin, sometimes snobbishly wide on the flank on the tire to decorate. They made the look of the vehicle to a delight even from far away. Here something moves along round tires. And even this trend nowadays gets out of hand to modern vehicles with broad aluminium rims in sizes of 16, 17 or even 18 inches. Still the classical white wall tires have not died out completely. Quite on the contrary, it appears to become the new fashion to restore old classic or vintage cars and sometimes to build modern high-tech in old shells.
  But unfortunately the supply of the original tires with the remarkable rings is difficult, almost impossible. You can get at least some tires from the american market, but these are almost always not licenced for Europe. ("P" tires have too low speed index).

Same optical effect: White wall tires or big aluminium rim

Way out?

Because of these reasons the so called ornament got spread out. The outward appearance looks like the original white wall tires, but the white wall was just a white ring produced out of synthetic material. These rings have to be wedged between tire and rim. Some people developed a method where the synthetic material got glued to the tire flank, to keep the classical black void between the white and the rim. But both got strictly forbidden by the manufactors. It was badly critiziced by many trade journals. Infact the tire is exposed to strong walkforces during driving, and this causes friction between the tire rubber and the synthetic white wall rings, which causes a strong damage of the tires in time. Besides the softener which is embeded within the synthetic material decays the tire rubber. And they will not look good in time; because of the airstream they loose contact to the tire flank and may rip off by curbstone contact. So they will not look delightful anymore.
  Another possibility is to vulcanize white rubber inside the tire flank with heat and pressure. The rubber is transported from the plastic to the elastic condition. This is forbidden by leading manufactors because of the grinding of a groove in the tire flank because this process is thinning the surface and may damage the layer of textile inside the tire. The tire may disform during the vulcanization. So this method impairs the driving condition and security risks.

Plastic rings mounted between tire and rim? Unfortunately forbitten!


The solution
 Our method is different from others; we use white raw rubber which is chemically identical to the black tire rubber when vulcanized. Only the black maker, the smut is missing. The tire flank will only be grinded on the surface to enlarge the surface and to remove the printings. We vulcanize the white rubber on top. This will not weaken the flank. Even the temperature during vulcanization has no negative effects on the tire; repairs of tires use the same method and temperature. Furthermore our process was tested by the manufactor Kleber (subsidiary company of Michelin) even for high speeds (240 km/h). No negative effects in respect to driving stability, security, longevity and walkability of the tire were noticed. And at the end we have more than 15 years of experience with our process; we have not had any problems or reclamations, and no dissatisfied customers.

Tire with approx. 40 mm wide, subsequently vulcanized white wall

Our process
  We have many vulcanizing forms in sizes of 8, 10, 12, 13, 14, 15, and 16 inches. These sizes cover most requests for white walls. Unfortunately we are forced to place the white rubber on the tire flank so that there is a space of about 15 mm between the inner side of the white ring and the rimflange, here we cannot vary. But it is possible to choose the width till the maximum of approx. 40 mm. On the finished product the white wall has a thickness of about 1 to 2 mm on top of the flank.

 Our rubber mixture is the result of a long development process, so its longevity is optimized. The rubber does not grow old faster than normal tire rubber and the white rubber does not detach under normal driving conditions and does not discolor even after time. The white walls can be cleaned from street dirt and brake dust easily by scouring agents or potscrubbers. If you have stubborn dirt you can clean it with waterproof fine sand paper.

special wishes?
 Besides the white rubber we can use red, green, and blue rubber and even combine them. Your phantasy is not set any limits. Just the before mentioned technical (and of course financial limits). For example we can put a white ring on top of a red one and lay open a small red one between a wider white one. The result would be a white-red-white ring. Of course this needs double expenditure of work. Obviously our process can be applied to all modern tires, too, and not only to vintage tires. So we can give your vehicle an individual touch with colored or white rings.

Or would you like it green or blue?

even colorful is possible. Just ask!

   The German federal organization of tire dealers and vulcanizers (Bundesverband Reifenhandel und Vulkaniseur-Handwerk e.V.) together with the German federal agency of moter vehicles has confirmed: "The process of making white or colored wall tires with the method of hot vulcanization according to the directive for reinstatement work on pneumatic tires (paragraph 29 and 36 of the German StVZO) represents - in the broadest sense - a professional tire repair of a tire with an E-(ECE-)label. Although the liability for material defects (formerly warrantee) and the product liability goes - through this "repair" - to the executor - as with all repairs - the tire does not loose its original E-(ECE-)label."
  But as executors we are obligated to mark our white wall (resp. colored wall) tires with a date of production (DOT-like with four digits) and our company marking (name and phone number) so that the claim of guarantee is ensured


Our white wall tires are marked on the inside; with our company marking and the DOT

Bottomline: You won't get any problems at the technical supervision authorities (in Germany TÜV).

(Probably) our white wall tire; the spot of the erased company marking is clearly visible. For such a manipulated tire we can not give any guarantee!
