Goodyear 'billboards'

[MaSnaka]

Hey Sideoiler10, Yes I'm happy with the MT's (ET Street Radials) and everyone I have met who use them seem very happy also. I have 235/60/15 in the front and 275/60/15 in the rear. The Cobras are light cars and the softer side wall is nice. On a heavier car I don't how the cornering would be. There are a lot of windy canyon roads out here (Mulholland Hwy.) for example that I frequent and these tires hold the corners very tight. I know another guy with a Superformance and I believe he has 275 fronts and 325 rears. That's more tread than I need but they look evil.

Nice look!

Geez, I'm confused relating to tire size - I currently have VR50's on my Cobra, 245/50 front, 265/50 rear - Roger Kraus Racing has billboards, 26.5X8.0 and 26.5X10 - is that equal to my rear tires with the 26.5 really mounted on an 8 or 10 inch wheel?

Avon tires are listed from 225/65VR15 to 295/50VR15, so it's easy to relate those sizes to my tires - but, Dunlop's are listed from 475/1000-15-CR65 to 650M15-CR65 - WTF?

Also, it's seems to me that the diameter is important with my current tires around 24" and the billboards at 26.2 front and 26.7 rear. I'm thinking that the higher diameter numbers will look the best, although more diameter may not result in a better driving experience, I'm clueless on this issue.

Anyway, any input will be appreciated.

cobra de capell:

The Mini Power Ball from Mothers makes polishing the centers on Torq-Thrusts a snap. Five minutes a wheel on my Typhoon, tops. There have been some other threads here regarding Billboards and there are a few places to get them. Billy Andrews at HRE probably knows who they are. Agreed on the 15-inch wheels. It's a matter of taste but 15-inches just look proper to me.

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,

Kevin, you pretty much outlined the trials and tribulations that many have to go through to get "the look." I ended up adding an inch of inboard width to my stock rear Trigos to get my 325/50's to essentially "set" better and not balloon at the rim bead. Cost me $350 for the pair...pro done.

Some cars are just naturally limited to what you can do, and the IRS in the SPF is no different. Even though I still have perhaps 2-3" of clearance to the coil-overs, I now have severely limited clearances toward the front of the wheelwells. These tires have an installed height of just over 27", so they fill up the wheel well nice, but I'd love to have the ability to tuck them underneath another 1/2" (will never happen). I have even eliminated the 1/2" spacer plate on the Trigo adapters, so that alone (and machining the inner hubs slightly to clear the Wilwood calipers) gives me that much more.

Whatever you decide to do, measure three times and cut once.

As for other Billboard sizes, I'd like to hear what others think of the alternative sizes available? I'd be curious to hear if anyone is running any of the G7 series sizes on their cars? More so would any of these alternatives prove to be clearance problems for front or back.

Contact Rick Parker on here-I believe he has G7's on his beautiful NAF Slabside.

Hi Dean,
I have G7's - 600x15 front, 800x15 rear. Just like when I had 295's up front, they rub on a lock-to-lock turn on the inside of the tire against the frame. Not smoke-pouring-out-the-wheelwell rub, but they do connect. The rears only rub the top of the fenderwell with the most bone-jarring of potholes or train tracks, but not 99% of the time.
I like the look of filled out rear fenders and these fit the bill for me. The fronts look good, would look better if I could lower the front end down further!
