Thank you for viewing. This is a finished product of thin tires (never run). Tires: Low friction black Wheels: SX chassis carbon dish Quantity: 8 pieces (for 2 cars) Tire diameter: 22.8 mm (flat tire) Tire width: 8 mm Bonus 72mm hollow stainless steel shaft x 4 Manufacturing process 1. 1.7mm wheel penetration (1.8mm penetration does not provide accuracy with Eagle's setter) 2. Hex hole shaping of the wheel 3. Wheel selection (only good ones are used) 4. Wheel rim small diameter processing (using a setter) 5. Wheel circular processing (using a setter) 6. Rough tire cutting with a 22.5mm setting of the Veracru cutter (using 24mm narrow tires) 7. Tire installation on low-height wheels with Hirogerunder (fixed with double-sided tape) 8. Check for tire wobble with a work machine (if there is wobble, remove the tire and go to process 7) 9. Tire processing with a tire setter 10. Tire edge chamfering We have spent time and effort creating these with a focus on precision, using Eagle's tire setter, P model lab's penetration jig, shaft blade reinforced wheels, Veracru cutter, Hirogerunder, etc. However, as these are handmade by an amateur, please refrain from purchasing if you are sensitive to such things. As a bonus, we will include 4 pieces of 72mm hollow stainless steel shafts that have been straightened to some extent. The case is also a bonus. Photo 5 ☆How to use ① Carefully attach the bonus shafts to the running machine so as not to bend them. ② Turn on the switch and rotate the tires, and lightly and evenly contact the left and right tires with a flat metal grinding stone of about 600 to 1000 grit until you no longer feel the vibration to some extent. (Finishing cut) ③ Wipe off the tire surface shavings with lighter oil. ④ If you lightly touch the rotating tire surface with your finger and it feels like it sticks, it's OK. If you still feel vibration, shave it again evenly, but be careful not to over-shave. ※ It is recommended to use a jig for inserting and removing wheels. You can insert and remove them by hand, but there is a high risk of bending the shaft. ☆Caution If the tires wobble due to going off course, there is a high possibility that the shaft is bent, so we recommend replacing it with a shaft with less bending. We try to ship the same day, so thank you for your cooperation.
