helloI'm assuming that you currently have the standard 175/65 R15 tyres on the carso you can get a 17" rim to fit and give nearly exactly the same gearing by using a 225/40 R17 tyre or a 195/R45you can't go much wider than the existing rim due to the suspension strut clashing this site is very useful for quickly comparing the effectshttp://www.willtheyfit.com/index.php?width=175&aspect=65&diameter=15&wheelwidth=6.5&offset=40&width2=195&aspect2=45&diameter2=17&wheelwidth2=9.5&offset2=20&Submit=Calculate#content so a wider tyre will greatly increase cornering and braking grip, admittedly at the expense of road noise and a penalty in fuel consumption ride comfort will reduce however as the tyre sidewall height comes down and you effectively make the the suspension stifferyou can counteract this slightly by dropping the tyre pressures and also selecting a tyre with a low load rating
