Tyre spec.

you could drop down to 16" rims, but now 205/55

hi there

that's the correct size for your car. changing the ratio (on the 17" rim) might affect your insurance in an accident.

anyway, what you need is a tyre with a slightly softer sidewall (they flex a bit more). something like a Vredestein sportrac3 would suit you best, imo.

you won't notice any loss in performance as you need to be driving like a idiot to feel a difference, but in normal everyday driving they will cushion the bumps a wee bit better.

Thanks for the replies guys, I'll bear your views in mind when I need to replace the current tyres.
