Just recently I have need to replace the tyres on my Austin 7 box. I then found out that I was running on 17" wheels when the should be 19" . I have been advised to change back to 19" which will ais stability and also matches the gearing. Does anyone have any advice on whether this is advisable and whether I should get the wheels I have re-built of try and find some new wheels?

Anyt advice helpful
