I have some 295/45/20 Continental UHP tyres availalbe for just £120 inc VAT each. These are a little larger than the OE 275/40/20s, but will fit without problem and give you a better ride due to the larger side wall. When the speedo reads 60mph you would actually be doing 63.8mph. Delivery on these is £5.50 per pair.

Thanks
