hi all, have been given some 18's off a relative with four good 225/40/18 tyres on, my astra is a 1.6 hatchback 4 stud, the whels are fine, fox multispokes, but im unsure about the tyre size, it will not be getting lowered as it is my everyday car and i use it for ferrying mine and a mates mountainbikes about at weekend, will they go straight on with no rubbing and not much drop in performance? ive searched on here for posts but have got mixed messages, some people run this size tyre and some don't, im just unsure if there worth putting on as don't want to ruin the useability off the car and can't really justify buying a set off 215/35/18, thanks in advance, andy
