I want to change the tyres of my japanease Weagon R, model 2023, 650 cc engine.
Currently, 155/65/R14 tyres are installed.
I have noticed when my meter gives the speed reading of 65 kph, google maps/speedometer apps give 60 kph (and for 100 kph, it gives 92-93).
So it seems the tyre size is smaller, but I'm not sure. I was thinking about 165/70/R14 or 165/65/R15 or even 155/65/R15 or 155/70/R14.
Moreover, from where should I buy good tyres in Islamabad? I have heard about Japan Tyres in Blue Area, one shop (chinese tyres) on the start of stadium road and some shops in Pindi Sadar (chinese tyres). However, I do not know which one would be the best. If someone can guide, it would be of great help. Thanks/
