Get your wheels from Discounttiredirect.com or Tirerack.com (tires,too for that matter) you can let them choose by make and model or youself using a wheel with 5 bolt x 4.5" (114.3mm) bolt circle and 40 mm offset with 66.5 mm center ring. One thing to remember is that the tires you want to use are about 26.75" diameter, 765 revs per mile. For diameter use this formula: tire section width x twice the aspect ratio in hundreths; result divided by 25.4 and that answer added to the wheel diameter, e.g. ((235x2x0.55)/25.4) + 17 = 27.17" diameter. I used this example because it is one of the few tires which, although correct, does not yield the actual rolling radius that calculates the correct value, which is 768 for the Pirelli tire recommended (400AA, 80k mileage warranty from discount tire direct). Thats why it is a direct replacement for the 225/60x16 tire which also has a rolling radius of 768 revs/mile By the way, several have commented on the darty/floaty feeling in the azera suspension. Although we have not finished our shock/spring motion testing I more suspect rear shocks are the culprit. The rears are so soft that the back end wants to wallow easily. our solution has been to lower the front by one coil (5/8") and install heavy duty rear shocks. Unfortunately, we had to custom make the rear shocks and they cost $100 each . But they really work.
