360 Wheel Upgrade Issues

I recalled reading that there were error lights and issues for owners that went 20" wheels on a 360. Cant find the old thread with a quick search.

Can someone advise on the best set-up (wheels, offsets, and tire sizes) drivability/handling wise or advise alternative(s) (e.g. should not exceed 19"x XX setup)? The upgrade is cosmetic as I do not track, but I do not want to sacrifice performance (to any great extent) for just looks either.

If anyone has pics of a mounted 20" CS style wheel on their 360, I would like to see them. Here is the proposed CS wheel style setup:

• Front wheel size: 20x8
• Rear wheel size: 20x10
• Front Offset ET: 28
• Rear Offset ET: 30

 

You will not have any ABS issues if you retain the overall diameter difference (% wise) of the tires the same as stock.

I went with a 19-in front, and 20-in rear on my F430.

Front tires are 245/35/19 and rears 305/30/20. My main reason for doing 20-in rear is because I absolutely hated that in stock form the rear sidewall is a lot more than the fronts. With the tire sizes I have now I still retain the factory diameters and both sidewalls match since the rear is a taller tire.

 

So in the case of your 245/35/19. Given a 35 aspect ratio nominal sidewall height reflected as a percentage of section width you did 35% of 245 or approximately 86 millimeters and added to the size of wheel? What is OEM diameter tolerance? What about offset?

This is exactly what I have on order for my 430. I will post photos and feedback but it won’t be anytime soon. The data you listed above was given to the sellers (if it’s who I think it is) of these by me. They were using some slightly different data and I straightened them out.

 

Sherrillt- (tire diameter in mm x aspect ratio x 2)/25.4 + wheel diameter gives tire diameter.
(245 x 0.35 x 2)/25.4 + 19 = 25.75"
