I am going to put 19" chrome rims on my S55 and discount wheel warehouse told me to put 255/40/19' in the front and 275/40/19's in the rear. tire rack said to put 255/40/19's in the front and 275/35/19's in the rear, which is correct? thanks, Chris

255/40/19 front and 275/35/19 rear is the correct combination
