Skinny tires are:
Better for mileage because of surface area,
More predictable because of load distribution with tire wall flexing and feedback harmonics which is all tire,
And better in plowing through the snow because to small contact patch dynamics.

And less rotating mass, so more power for acceleration, snappier handling.

They look like motorcycle tires, I am amazed it handles as well as it does to be honest.

I will say it is a beast in down pouring rain. Never a hint of aquaplaning.

skinny tires

Read about the greatest Fangio he could tell you a thing or to about skinny tires,
with the seat of his pants.
In case you have never read about him, he drove by the feel in the seat of his pants
like no other driver, thats why he was world champion 5 times.,and yes on skinny tires.
Thankyou PWD TLs for showing us that fabulous vidio.

Tires? All tires were skinny when I was a kid, remember reading about Spa-Francorchamps, Fangio and Moss in R&T.

Driving in only an open-face helmet, wearing a short-sleeved t-shirt and street clothes...


Also, Malmedy (a corner on the track) was the scene of a terrible Nazi massacre of dozens of captured US soldiers in WW2... famous. Was portrayed in "Band of Brothers"....
Machine-gunned in the snow.

Seems obvious now, back then the lack of safety on cars or tracks.
