There are 2 different gear ratios??? I didn't know that. Does it have any connection with rim radius?
As I know, there are three tyre types: 1) 195/50-15 2) 185/60-14 - both in Germany-Opel 3) and 185/65-14 in GB-Vauxhall . Can you tell me which goes where?
I thought that because of the different tyre profile 65 vs 60. there was different gear ratio. If you calculate combination 65 and lower gear ratio VS 60 and higher gear ratio, you will see that it gives the same speed.
Anyway thanks probably 3.42 in Switzerland .
