#DavesCarIDService begins today with a bit of mystery; car #2 is definitely 31 Buick Series 90 but car #1 seems to be a different 31 Buick roadster, sporting what I think are either aftermarket Clark Firestone or General Jumbo wheels
Although photo #2 says Betty & Billy are playing in 1932, plate indicates 1931. Note wheels on #1 car, containing Myrtle and Frances: AFAIK, no stock car pre 1933 had steel artillery wheels, thus my guess at aftermarket
*Firestone and General began offering "balloon" tires for softer ride around 1931, requiring smaller diameter wheels, made respectively by Clark (Firestone) and Cleve-Weld (General Jumbo). Gramps seems to have sprung for a very early set of these.
Also, either Gramps didn't put the hubcaps back on or he was a victim of hubcap thieves
Wheel/tire dimensions evolved with road technology; in days of rutted dirt roads, skinny buggy style wheels made sense, but as roads became more gravel/paved, wheel diameter became smaller and tires fatter
On the other end of the tire/wheel spectrum, this Donk-style 1968 Pontiac Bonneville is sporting rubber band tires on I think either 26" or 28" rims
Lingo lesson: "Donk" now generically refers to old big body car jacked up with huge rims, but originally referred to a Chevy Impala shape:
Donk: 71-76 Impala (flat front / sloped rear, like a donkey)
Box: 77-90 (flat / flat)
Bubble: 91-96 (slope / slope)
Donk: 71-76 Impala (flat front / sloped rear, like a donkey)
Box: 77-90 (flat / flat)
Bubble: 91-96 (slope / slope)
This rat rod cry for attention appears to be a circa 1939 REO truck cab, chopped, with a circa 1960 REO grille, on handmade tube frame with Cummins diesel engine, Dana 60 rear dually axle & old semi wheels.
Needing a custom car palate cleanser after those last two, and this did the trick: here is "CadZZilla," a 1948 Cadillac radical custom. Designed by Jack Chisenhall & Larry Ericson, built by the late Boyd Coddington for Billy Gibbons of ZZ Top fame
Quite a few rock guys in the hot rod/custom car scene: Clapton, Jeff Beck, James Hetfield, Kirk Hammett, Jimmy Vaughn, Travis Barker, but Billy Gibbons is probably King of the Hill in that regard
I think my proudest hot rod moment: Billy Gibbons taking pics of my heap backstage at the 2010 Crossroads Guitar Festival Chicago. Son and I got to hang out on his tour bus and yak about cars afterwards. 
*long story, but a friend did all the staging for the festival (at Toyota Park stadium Chicago) and asked another friend & me if we would lend our cars as conversation pieces for the Fender courtesy tent backstage. Met many of the performers as a result, including Beck & Clapton
Behold Eric Clapton in Topsiders mesmerized by free Lou Malnati's Chicago Deep Dish Pizza
my boy Hawkspawn, then a 13 year old aspiring guitarist, was pretty starstruck by the whole thing. He got to hang out in the Fender tent and play the guitars, resulting in a compliment from & short jam with Cesar Rojas of Los Lobos. Hawkspawn is now himself a pro musician.
I'm pulling the plug on this thread, it sorta became Dave's personal anecdotes rather than Dave's car IDs
