Guys looking for an opinion here. I have just purchased a CLK320 2003 and i need two new rear tyres, roughly about £150 cost wise, bear with me. Now with my 'blokes' logic, I'm thinking maybe now is the time to upgrade to 18" wheels and tyres, it would cost me roughly £950 but i could sell my exisiting wheels and tyres for say £200 ish plus the £150 i would have to spend anyway (for the 2 tyres), means I would be spending an extra £600 for new rims. See told ya blokes logic . I was looking at these of eBay...eBay - The UK's Online Marketplace With some Falken Z912's fitted (225/40 front and 245/45 rears), after reading a few threads they seem a resonable tyre for the price, i know we all have our own opinions and experiances on tyres and tyre brands so i don't want to open a discussion on that here. My question is ....... Shopuld I go for it and get 4 new wheels and tyres or just stick with the standard 16's and get two new tyres?
