Friday night topic - most power through most narrow tyres
Discussion
I just drove an R56 (third generation) MINI John Cooper Works on the track with 230bhp and what looked like stretched 205s, but I'd want more tyre ... I used to run my ~230-240bhp R53 (first generation) MINI Cooper S on 185/65-15 Nokian Hakkapeliitta5 studded winter tyres - great for gentle drifting - but now I run 195/55-16s in winter which are the stock (summer) size.

637hp, <750kg, 7.00 x 19 (cross ply - so less than 175 contact patch?)
The sound of it in the mountains.

The same pass the two british men sadly died driving yesterday.

Makes everything else look pretty gay to be honest.
My 1971 Lotus Elan Sprint: 126 bhp runs on 155 x 13" radial tyres - weighing 12cwt or 1,344 lbs (whatever that is in new money) !
I've just done a power to weight ratio comparison that equates to 210 bhp / imperial ton.
I have just checked the specifications on my 1997 993 Carrera S. It has 281 bhp with 285 x 30 x 18" rear tyres. It weighs in at 3,186 lbs giving a power to weight ratio of 198 bhp/ton
PS. I am not a mathematician - used an online motoring calculator as I ran out of fingers and toes :-)))

I was foolish enough to fit 205/35/18's to my MR2 Turbo that was tuned to about 320bhp at the time.
When I drive it sideways up a kerb, over a verge and into a fence I replaced those with 225's on the back.
It was annoying as the car really did need staggered wheels and tyres but there's not too many manufacturers out there that make wheels in different widths. I ended up having staggered tyres on the same width wheels (didnt come with OEM Wheels before anyone says it, they were gone long before I bought it)

I had 225's on the front of mine and 245's on the back and that was only an NA. Never went sideways unless you wanted to to like that. Could corner at amazing speeds without any fear.When I drive it sideways up a kerb, over a verge and into a fence I replaced those with 225's on the back.
