thanks and any recommendations on tyre pressure? i usually have the fronts on 32 and the rear on 34-36. since im chaing the size do i need to change the pressure aswell? thanks for your replies guys

You should be running higher pressures in the front - reduces understeer.

I'm running 38 all round (only because of AWD setup) on a 235/45-17.

The standard rim is 17x7.5 and will take a 235/45R17 however a 225/45R17 is better suited to that wheel and that car.

thanks for your reply's guys looking forward to putting them on, im gona have 235 at the back and 225 at the front

Why? That's not smart. The fronts do the steering and the braking. That's very important stuff. More important than "putting the power down" or the staggered look. Plus, you cannot do any tyre rotation at all if you run different sizes. Given that a smart approach to balancing tyre wear is to buy a pair at a time and put them on the front, rotating the old fronts to the rear and only buying another pair when the tyres on the back are down to the limit, being able to run the same size all around makes a lot of sense.

I'm interested, what do you think you'll achieve by the 10mm extra contact patch (in theory) and extra sidewall height?

Who are you asking?
