Taller wheels on AWD c3

[Mike Kastens]

I’ve got a 2001 AWD C3, low miles, still in great shape. I want to update the look of it but not sure the AWD system could handle going from a 18” wheel to 20”? Wouldn’t the system think something was out of whack??? I guess if you kept total diameter the same but that seems like very low profile tire on a truck?

As long as all 4 tires are the same size it shouldn't be an issue. The computer wouldn't be able to tell if all 4 tires changed in size, although your speedometer would be inaccurate. That being said, you can use a tire size calculator on the internet to find a tire size for an 18 or 20 inch rim and match the stock outside diameter. You can buy a new truck with a 20 or even 22 inch rim, and those tires are pretty low profile
