I will probably put on wider tyres on it, and maybe slightly shorter tyres. Will this have a great effect on top speed? I really don't want to stick with the original tyres, apart that they look horrible, they have no grip at all. I enter at a roundabout in 2nd gear barely moving and floor it the back just slides out like nobody's business with the stock a12 which has been running daily for 33 years... So yeah you can imagine what its like in the wet! Ihave to change them
