Attended a big Hot Rod show today. I got talking to the guy that sold me a set of 17" Boyd Coddington smoothies for my wifes car. He showed me the new 20" version and it got me to thinking again.
I put one of the Smothies on the front of my cobra a while back to see what it would look like and I liked it but I figured I'd go with a 17" Halibrand.
The 20" tires would fill up the wheel arches a bit better than the 17s as the OD of the rear 285/30/20 is 26.8" as compared to 25.7" for the 315/35/17. Fronts measure 245/35/20 with an OD of 26.7" compared to 25.4" for the 235/45/17s.
I think the 20s would look good but I'm interested to hear other peoples opinions as well.
Here's a pic of the 20" rim above some 17" rims.
Cheers
