I love the Billboards on Cobras, they just make the car look even more "racier"
To each it's own, but any larger than 15" make the cobra too much like a hot rodded car, and I love Hot Rods. They just look too big for such a small car. I don't think anyone, can honestly say that the ride of 17" + low profile tire, isn't real harsh. Now for racing, I can see how the wider and taller tires help a great deal. Plus, for 15's, there is not much of a selection of tires.
Here's a question like several of you have asked. I would like to have Billboards on mine too.
My front wheels are 15x8 with 235/60 tires.
The backs are 15x10 with 295/50's. I changed my tires from 60's to 50's for a wider tread and, the fatter tire just looks better. But, now that I've lowered the rear, I get some tire rub. I will not raise the rear back up because I don't like the "raked look", nice & level and having the wheel well filled up with tire is the look I want.
Here are some of the things I can do for the back.
Go back to the 60 series taller side wall but sacrifice the wider tread.
I believe my back spacing is 4.75" and could order new wheels. ($$$)
Narrow the Currie 9" rear end tubes & axle. (lot of work and $$$)
Adjust my QA-1 shocks for not compression. (
)
I would have to guess, the better & leased expensive, is to buy the Billboards in a 60 series.
I sure like the look of the original cobras or Kirkhams, with the wheels/tires tucked way into the wheel wells a couple of inches. I will never have this "look" unless I narrowed my solid rear end. Even then, I think the tires would hit a brace that's part of the frame and would have to at least notch it. It makes a triangle to the frame for strength. Damn,.... I wish I could afford a Kirkham. lol !
Two fine examples of the "tucked in look", are in the pics below. What great machines these are !
If I go back to the 60 series tire for the back, I'm having problems comparing the 295/60 to the Billboard diameter numbers ect...on Rodgers site.
Please help my pea size brain, (I did pass 12 grade's of education,............... 6th grade twice) on which Billboards I need for my wheels.
Thanks,
