I found some replica audi wheels(18x8) for really cheap and I need some tires for it... I was thinking 225/ 40-18, but apparently that wil make it look stretched horizontally... anyone who is an expert or some one who knows about this stuff helps me... what is the best fit for 18x8 wheels...

this is the link to the wheels:

oh btw the stock tires dimensions are 195/ 65-15

 

I think 235/40-18's would be good, and look real nice on those rims
