What is the tire size of the Jog i125?
2 Answers
The tire size of the Jog i125 is 90/90-10. Tire specification location: The original tire size can be found in the owner's manual, on the left front door frame, the storage compartment door, or the fuel tank cap. You can also find the tire specification information on the sidewall of the existing tire. How to read tire specifications: The tire specification is 195/65R1591V, where 195 indicates the tire width is 195mm; 65 indicates the aspect ratio (the percentage of the tire's section height to its width) is 65%, meaning the tire's profile; "R" stands for RADIAL, indicating it is a radial tire; 15 represents the rim diameter in inches; 91 is the load index; and V indicates the tire's speed rating.
I've been riding the Yamaha Cuxi i125 for a long time, and its tire sizes are 120/70-12 for both the front and rear wheels. This size is scientifically designed: the 120 width provides sufficient grip, especially making turns more stable during urban riding; the 70 aspect ratio balances comfort, so it's not too bumpy when going over speed bumps; the 12-inch wheels make the bike agile and easy to park. I think choosing the right size is crucial because switching to non-original specifications can affect braking performance and safety—for example, tires that are too narrow may skid easily in the rain. It's recommended to check tire wear and pressure every six months, maintaining around 28 psi to extend their lifespan. When replacing tires, go to a professional shop and don't skimp on costs. Brands like Cheng Shin or Kenda are good choices—safety comes first.
