Thank you for viewing. This is a completed set of Pera tires (never run). Tires: Low friction (maroon) Wheels: Carbon fin, cap removed Quantity: 4 Tire diameter: 22.8 mm (flat tire) Tire width: 8 mm Manufacturing process: 1. 1.8mm wheel piercing 2. Hex hole shaping 3. Wheel selection (only using good ones) 4. Wheel rim diameter reduction (using a setter) 5. Wheel cap removal, deburring 6. Wheel circularity processing (using a setter) 7. Rough tire cutting with a Pera-Kuru cutter set to 22.5 mm (using 24 mm narrow tires) 8. Tire installation on low-height wheels with a Hiro-Gellunder (fixed with double-sided tape) 9. Checking for tire wobble with a work machine (if there is wobble, remove the tire and go back to step 7) 10. Tire processing with a tire setter 11. Tire edge chamfering We have spent time and effort creating these with precision, using an Eagle tire setter, P Model Lab piercing jig, shaft blade reinforced wheels, Pera-Kuru cutter, Hiro-Gellunder, etc. However, these are handmade by an amateur, so please refrain from purchasing if you are overly concerned about details. *We recommend using a jig for inserting and removing the wheels. It is possible to insert and remove them by hand, but there is a higher risk of bending the shaft. ☆Caution If the tires wobble due to going off-course, there is a high possibility of a bent shaft, so we recommend replacing it with a shaft with less bending. We aim to ship the same day, so thank you for your cooperation.
