how tall of a slick did they run in prostock?
 

Hey guys got another wheel/tire question lol. What size slicks would grumpy and them have ran in the late sixties early seventies on the cragars? Also how wide? I was thinking of getting the 29x12x15 m&h for my 15x8 cragars I should be getting soon. Thanks guys!

Thanks,
Vinnie.

Although this isn't his '69, it's a pretty good shot of the rear tires on one of Grumpy's Pro Stock Camaros.

I'm not sure I'd put more than 10" of tread on an 8" wheel, but maybe that's just me.

I believe running a narrower wheel allows you to run a lower pressure that leaves a longer contact patch and still plants the inside of the tire on the track rather than just the edges. Get's a little squirrly at the top end though.

Thanks guys! Verne I love the way that the wider tires buldge out it looks so tough! And I think that's exactly why they did that.

Verne is correct again. Low air pressure is helped by a narrower 4-5&quot; rim to flatten the tire for max bite.
Those guys ran 28-29&quot; tires on the SB cars and 29-30&quot; on the BB cars for 6&quot; slicks.
Your combo Vinnie sounds like a SuperStock set up in the early 70's. Will definetly fill that wheel well up.

These look like 11.5 -12.5 on a 8-9 inch Cragar SS. I doubt they're 10 inches, L 60's are 10&quot;. These are outside the fenders with a deep backspace and Raised suspension.
Wrinkle Walls to boot, Later in 68, early 69 His Cars had the &quot;newest version Wrinkle walls&quot; we all came to admire and know. Too bad the rubber &amp; sidewalls on those was so thin they dry rotted faster than the non-wrinkle walls, leaving very few original or NOS tires for us today.
Any body have a set of 7-8 inch x 27-28 inch wrinkle walls ?

Again not his '69, but look at that sweet, sweet wrinkle wall action!

Now that's what I'm talk'n bout

This pic is much later in the life of the '68 Car. (he ran this into '71-'72 if I'm not mistaken in class,match races &amp; the defunct pro drivers league)
Notice the heavily altered wheel wells and vast amounts of sponsor decals.
Another &quot; trick he used on the front eye spring&quot; was to use Nova Spring cups to lower the front spring bolt, hence raising the car.
