Just taken my 58 hse into the local tyre place to find I need 3 new tyres. 1 has around 2-3000 left on it but thinking may as well get 4. Had the con ti's since new and just done 20,000mls. Replacement conti's are £250each Inc vat and he offered me pirellis at £840 ... Any advice ????

As long as the pirellis are the P Zero ones. I had them on my last sport and lasted 36000 miles. So pirellis for me every time.
