Depends on the profile on them. Lower profile tyres lower the gearing and increase acceleration and also will make the speedo read a lower speed. Higher profile ones increase the gearing and reduce acceleration and increase the speed your speedo will be showing. | |

Try this website to find the best match. You can see the difference at different speeds too. | |

yeah, you need to calculate the rolling radius of the original and try and match it by lowering the profile of the tyres. | |
