Wider Rear Tyres ?

[25stagea]

hey guys im getting new rims for my rs4 and was wondering if i can run 265/19 on the rear and 245/19 on the front , or is this going to stuff the ATTESA system up ?

Hey Lachy, this has been covered heaps of times, search is your friend!

Basically, long story short, it's not recommended, but if you MAKE SURE that your rolling diameters are the same for the front and rear, then you should be able to get away with it.

Hey dude. So the wole deal with the roilling diameter is because the attesa system engages when it senses 5% or more rear slip in the rear wheels (ie. rear wheels turn 5% more than front). So as long as the rolling diameters are the same all should be good and act as normal. So the width shouldn't affect the system.

I haven't got new mags yet so I can't speak from experiance. But knowing how the system opperates I'd say it won't affect it. When i get mags im planing on more dish at the back.

On a side note, i noticed that the attesa system was engaging more often simply cause of the diff in tyre preasure in my tires, as diff in pressure results in a diff in rolling diameter.

Thanx for the advice guys

and yeah i noticed the front driving a lot more as i have a slow leak in one wheel.

I will just go same size io think

265/35/19 will just have to ensure off set is correct
