An interesting debate. So you appear to be saying that these tyres will make our cars:
without doubt. Yes. categorically.
The Pirelli's only competitor would be an Avon CR6ZZ https://www.longstonetyres.co.uk/vintag ... cr6zz.html
because that is the only other tyre that has a carcass designed to compliment a chassis like yours, importantly the carcass is designed to compliment a car that rolls more in the corners than modern cars. And is rear wheel drive.
So if you want to make your car benefit from the extra grip that a modern tyre carcass offers in the corners you have to spoil it, as a road car, by stiffening and lowering the suspension and add caster and some adverse camber. and with respect, that sort of adjustment to actually get this balance right takes hours of testing and is beyond the bounds of a mere mortal. that is the sort of thing you need a proper test driver and careful adjustments to get the balance right.
Without doing these adjustments your car will not handle as progressively on a modern tyre carcass, because when it gets close to the edge of grip then it will loose traction more suddenly.
The handling thing to me is the massive advantage with the Pirelli
stop better (in all conditions)
well no, you can't have both. straight line braking comes at the expense of handling to some extent
In a straight line, a good quality modern tyre in the same size will present a little bit more rubber to the road. However only if it is a top quality tyre, will the compound be as good as the Pirelli. So a modern tyre of similar quality to the CN36 (So probably only really Pirelli, Michelin or Goodyear, maybe Conti or Bridgestone) will stop slightly better in a straight line than the CN36. but a budget tyre will not.
Fitting fatter foot print tyres will improve your stopping distances in a straight line.
However in unsettled braking, then the handling benefits will help you bring your car to a holt better on the CN36 because you will be able to feel what is happening better, and it will all round be more progressive. so less likely to suddenly totally loose it.
A German magazine did a modern tyre test on the CN36 tyre a few years ago, and this is the real clincher; in the braking test
In dry braking the CN36 scored 1
In wet braking the CN36 scored -1
So although it is fair to say more rubber on the road will stop you better in a straight line the CN36 scored near as damn it the best possible score. that is down to build quality and compounds.
and have a better ride than modern tyres?
comfort wise, a top quality modern tyre of the same size will give similar comfort.
A CN36 will drive in a straight line better on our rutted motorways. the steering will self centre better and the car will track less.
If you go lower profile you will sacrifice comfort.
If you go wider you will increase tracking.
If that can be proven, I'd happily use them in preference over my current Dunlop Street Response2 tyres.
I for one certainly don't buy tyres based on price, I buy them based on whether they are SAFE, regardless of cost. I'm sure that the majority of owners do likewise.
