Alcoa Wheels and What Tires?

Recommended Posts

Hey All, looking for some guidance on shoes for the snake. I have ordered the new Alcoa Wheels from SAI and I am looking for suggestions on what to wrap them with. I have seen the articles and information about what the SS and KR will be wearing. Pirelli PZero Nero 255/35 ZR20(Front) and 275/35 ZR20(Rear). I called SAI and they mentioned that the SS and KR packages will have the option of the Pirelli or Michellin Sport PS2. I want to go as wide as possible but don't want any problems with rubbing. I am not looking to do any racing with these on but dont want to give up performance.

 

Has anyone out there put 20 inchers on? How does it look and did you do any suspension mods? What tire sizes are working. Thanks for the help!!!!!!!!!! Pictures are very helpful too!!!!!

I went with nitto 555's 255/35zr20 and 285/30zr20.

I believe the wheels are 10 inches wide in the back. Will the 315s still fit? What would be the widest?

From everything I have read, the 285's are starting to get tight. You could take delivery of the wheel, mount the wheel, then do some carefull measuring. Discount tire has a tire size calculator you can use to get the exact dimensions of the tire size you are proposing. Remember to leave a little clearance for tire and axle movement (sideways). I would go to any less than 1/2 inch, which might not be enough if you really corner hard.

 

Measure both sides because the axle could be offset slightly. You might want to consider a panhard bar too to keep the axle from move around too much.

 

Hope this helps.

Carnut- thanks for the info. Much has been said about the suspension and panhard bar. Please tell me what the panhard bar will do in conjunction with a suspension upgrade. I don't know if I am going to do coilovers or possibly the Eibach Pro series plus kit. From what I know this is what they will be putting on the SS and KR. The eibach rep said you don't need a panhard bar because the extra wear on the tires,etc is very minimal.

 

Looks like the wheels are coming 8/16. That means 9/1. I don't think I can wait that long! :waiting:

The panhard bar is basically a bar the runs parallel with the axle and has a rotating joint at each end. It keeps the differential and axle housing from moving left and right and makes the car more stable. The standard suspension relies on rubber joints in the control arms to keep the axle from moving. The control arms are perpendicular to the axle and want to bend the rubber joint. Since the rubber will give, the rear axle housing will too. The panhard bar reduces this considerabily.

 

Because the rear axle housing moves up and down and the panhard bar is mounted on the axle housing on one end and the frame on the other end, there will be a small amount of left right movement when going over bumps but it is a lot less that the stock suspension.

 

As far as tire wear is concerned, I don't think I ever heard of anyone ever using a panhard bar to take care of that. The panhard is there to take the wiggle out of the backend of the car.

 

Hope this helped. If not, let me know what I missed explaining.
