I had 4 of these fitted to my 145 when i bought it. They were brand new then and the grip was very low right from the start.
Traction losses were frequent and that is not the cars fault since it uses the Tipo platform wich is known for the fantastic grip and handling it can provide, The braking power is....none. On good pavement they tend to slip with trajectory corrections needed and on bad pavement roads they just don't brake the car, they seem to only slow it down. Without ABS (tryed it also) they just lock as the braking force becomes harder .
In the wet thay are dangerous to say the least. They tens to "lift off" from the road even in low speeds and about 2cm of water and without warning so they are DANGEROUS. The feedback from the road is a mix: well....you do feel all the road since they don't filter any bumps and cracks but when you make a fast change in direction they seem to slip all over the place. Maybe in a lighter car that doen't show so much. I must say that the 145 can (and should) have 185's and these were 175mm wide and that they simply can't deal with this car. The 145 Alfa (in Portugal at least) is allowed to used 175 or 185's.
Returning to the tyres - After some time they turn into some kind of plastic and become even harder and start to make a lot of noise as they pass the 70-80km'h mark,
So off they went as soon as the car restoration ended and were replaced by some Toyo CF2's wich are the best tyres i've had except the Goodyear Eagle F1's. And i've had Michelin, GoodYear, Vredestein, Sava, Marshall, Continental, Firestone and Hankook tyres God...i'm getting old lol
