One of the car mags did a handling test using a BMW 328i equipped with different wheel diameters from 16" to 22" with attendance change in profile to keep the overall diameter the same. The car got notably slower as the wheel diameter increased, and handling was optimal at 17-18" . The rest is aesthetics, even speed of turn in didn't benefit.

My Boss 302 Mustang has fat tires. Front: P255/40R19; rear: P285/35R19.
The factory tires for my 1967 289-4V Mustang were not fat. Or low-profile. 195/75x14.

radials hadn't been invented in 67

The first radial tire designs were patented in 1915 by Arthur W. Savage, a tire manufacturer (1915–1919), and inventor in San Diego, CA.^[3]^[4] Savage's patents expired in 1949.
Michelin in France designed, developed, patented, and commercialized the radial tire.^[5] There is no evidence that Michelin had knowledge of Arthur Savage's earlier work.^{[citation needed]} The first Michelin X radial tire for cars was developed in 1946 by Michelin researcher Marius Mignol.^[5] Michelin owned the leading automaker Citroën, so it was quickly able to introduce its new design, including on the new 1948 Citroën 2CV model.^[6] In 1952, Michelin developed a radial truck tire.^[7]
Because of its significant advantages in durability and fuel economy,^[8] this technology spread quickly in Europe and Asia in the 1950s and 1960s.^[5]^[9]^[1]

hmmm, maybe didn't become popular here in the farm area quickly.

I remember riding in my grandfather's 1971 buick LeSabre on radial tires. They made slapping sounds hitting the cracks in the highway at 60mph.

Hah, that 71 LeSabre with the 260hp 350 became my father's car. It was the car I learned to drive in and the car I drove until I got my first car as a junior in high school.

Hence no "R" in the Tire Code.

I should say, my '67 Mustang didn't come from the factory with radials. I put BFG Radial T/As on it, about 225/60x14. I really should have upgraded to 15" wheels, but I was always operating that thing on a shoestring budget.

The first factory car with radials was a 1973 Continental, in the US. Europe was using them earlier because of Michelin, which apparently is one heckuva tire company. They are HQ's in a rather interesting smallish city near the south of France in the mountains almost.

that's very close to what I put on my 70 Nova SS
and shoestring budget is what I had
bought the car in 1980 for $700
needed paint and tires

I had a '73 Nova with the 350 and the new ugly bumpers. Had bucket seats and floor mounted shifter, was pretty cool I thought. Came with bias ply raised white letter tires. They had dropped the SS moniker by then. It was fast for its day, I think the mags had 0-60 at 8.5 seconds.

Anything under 10 was "fast". Not many new cars today are over 10 seconds.

https://www.motorauthority.com/news/1128325_the-2020-cadillac-ct4-v-s-engine-has-a-unique-turbo-design-in-the-name-of-torque

The CT4-V uses a version of General Motors' L3B 2.7-liter inline-4, first seen in the Chevrolet Silverado pickup truck. As Fenske is quick to point out, General Motors made a big deal initially about this engine supposedly being a truck-specific design, likely to assuage buyer wariness of a 4-cylinder engine in a full-size pickup.
Just like the name says, the engine's dual-scroll turbo has two "volutes"—the passages that circulate air through the turbo. They're stacked one on top of the other. This is similar in concept to a twin-scroll turbo, but the latter places its passages side by side, Fenske noted.

In the GM engine, the dual-volute turbo is paired with an integrated exhaust manifold. The combination helps separate exhaust pulses from individual cylinders, which improves response. A twin-scroll turbo works on the same principle, but is slightly less efficient, Fenske said.
A twin-scroll turbo directs exhaust gases to just one side of the turbine, while the dual-volute setup sends gases to both sides. That ensures that the maximum amount of exhaust gases are used to spin the turbine, getting it up to speed more quickly. The dual-volute setup also shortens the distance between the exhaust passages and the turbine, further improving responsiveness.

Driving fast in Germany ....

The last time I was there I had a rental Diesel sedan, a Vauxhall I think, and it would do 180 kph before getting wobbly. The speed limits in that area were off and on a lot so we didn't have more than 4-5 miles of unlimited. I spent most of my time watching the rear view mirror.

It would be kinda neat to have an unlimited tollway somewhere in the US.

C8 will run size 275/30R20 tires up front and 345/25/R21s in the rear. That's 10mm narrower at the front compared to a C7 Z06, but 10mm wider at the back.

Even a modest pot hole could dent those rims.

I haven't seen "Vauxhall" mentioned in a long time.
I was unaware that it is still a going concern.

Yeah, some supercars are now offering carbon fiber wheels - relatively a lot of weight loss.
