Hi
I've got to tell you, i have the original 155HR15 CA67 Pirelli Cinturato fitted and they are epic. I have gone a bit posh and fitted Borrani wheels too.
I raced it at Snetterton last weekend, mine is a standard road car, but in the corners it was epic on the Cinturato. It held it's own against much more powerful cars on racing tyres in the wet. On the straights though i was blown into the weeds.
I think one of the things that is critical on an Elite is that because they roll so much in the corners you do need a period tyre to keep the handling progressive. A modern tyre carcass needs a much more rigid suspension set up with adverse camber, to attempt to keep the foot pit flat on t he road, where as period tyres are designed to be fitted to cars with softer suspension and no camber, so as the car rolls it doesn't pick up the inside edge of the tyre and loose grip suddenly, it starts to do it a little earlier but it does it in a progressive manner.
