Hey guys,

I'm considering buying a set of Advan RG II's in the following sizes:

18x8 45mm / 18x8.5 50mm

Can anyone tell me if those offsets are going to limit my tire size options? I will be runnng the car at autocross.

 

Always check the rules first.

Generally, 18" wheels bump you out of stock and into classes that will cause you to spend a whole lot more money.

 

I'm in Canada, in CAC rules the rim size doesn't bump you out of stock. When I come down to the US to compete I'm going to run R's on the stock rims.
