The original rolling radius is 309 mm. Yours is 294.8 mm. (14/2*25.4+195*60/100). You are driving at 95% of the distance it should be. For an example, If your drive for a distance of 100 km, your meter will read 105.2 km. However, for the engine oil changing, you should count on your meter since your engine works as hard as you drive for 105.2 km. (it is not a big different if you change your engine oil sooner or later just only 5%.)
