However many people do want a wider tyre, If you do think you want a wider tyre then 185/70VR14 PIRELLI CINTURATO CN36 or 185/70HR14 Avon CR6ZZ | Longstone Tyres are the only really good options. Pirelli for road use and CR6ZZ for racing. However you will only benefit from wider tyres if you are getting too much wheel spin or locking up the wheels under braking.
These 185/70R14 tyres are tyre carcasses that are designed to suit a car like your GTV. all the other carcasses in this size are modern tyre carcasses that are developed to be fitted to a completely different kind of set up.
fitting wider 15" wheels does not open up a selection of better tyres. quite the opposite there is a greater variety of not as good tyres that are not suited to your car but yes they are cheaper.
However i think that 185/70VR14 Pirelli Cinturato CN36 is very good value
Dougal is on a myriad of forums for all different marque's purely to advertise the tyres he sells. It is very predictable when he's going to pop up. Can't blame him for trying but it does get very tedious
And the distributor for the specialist Pirelli Cinturato range of tyres in the US is Pirelli Cinturato buy on line or ring -- 1(800)952-4333
Hi GTA R. Sorry Steve, if i wasn't clear. As much as anything the reason in my post is that these cars ride better on 14" wheels, which is why Alfa changed to 14" wheels, In i believe 1968 (ish). which incidentally is the same year that Alfa had the opportunity to start fitting low profile tyres, which they chose not to do.
