cheers dirty harry,whats the nearest aquivalent to stock sidewall height you can get?

 

[Dirty Harry]

I would compare them at the tire shop to make sure you make the right choice.

Good resource that Joval, but what happens when the tyre size doesn't state aspect ratio?

eg my stock bus tyres are 185 R14, but make no mention of aspect ratio (eg 185 65 R14) That converter seems to need that middle figure, or am I missing something?

 

[Joval]

When no ratio is given the default is 80.
