    Evening all,

    SO I am thinking of getting some nice new fresh alloys for the car. My question is I currently have 15' wheels, what size can I go up to , as in can I put 18' wheels on. By increasing wheels size what does it add to the car, performance wise.

    Well what car is it? Are the current 15" an approved size for the car?

    In relation to performance, you should keep the same rolling radius ideally i.e. bigger rim with lower profile tyre. This will ensure the speedo stays accurate and you wont be putting extra forces through transmission etc. Allloys are supposed to be much lighter than steel wheels and a theoretical advantage would be had from this but depending on what you are driving, you wont notice.

    You can go bigger alright but an 18" wheel and tyre is going to weigh a fair bit more then the 15's on the car unless you go for an expensive wheel such as bbs/oz superleggera.
    Replica wheels are very heavy which will dull performance and if it's a 1.4 golf don't do it, big heavy wheels will kill your gearbox.

    Be careful, VW gearboxes are crap and fitting 18" wheels will put a lot more strain on the transmission.

    Yes I'd say so, keep a look out for a set of wheels from a higher spec model, maybe a cupra or FR spec, these wheels may look better then whats fitted.

    my brother recently fitted 17 inch wheels to his avensis which had 15s, they are official toyota wheels and come as standard on higher spec avensis. The tyres have a rolling radius 15% larger than his old ones. Its hardly bad for the transmission, is it?

    18's will fit no bother on an A4. Make sure they are the right fitment before you order. The spare wheel will be a smaller sized wheel, it's possible to drive on but obviously would have it's effects.

    No, lol. The offset of the wheel. What wheels are you thinking of buying. All wheels don't fit every car.

    As long as they are they same fitment your grand. Wheels can be gotten in different fitments. Just be sure to be sure they are the correct size for yours.

    Many cars have the tyre sizes listed in the manual, not only the standard ones but sporty ones as well.
