Alfa GT: Biggest Wheels Possible

Some advice please. Can I fit 18" wheels to my Alfa GT? If so what are the benefits/drawbacks? Is it possible to fit 18"? Any suggestions on a good tyre/alloy if so. Thanks in advance.

The car came with 8"x18" as std or an option. So: Yes.

The main benefit is that 18 inch wheels look cooler to some people. Also, depending on the wheel and tyre choice, you may lower the unsprung weight slightly by using 18 inch wheels, which theoretically improves acceleration response.

The main drawbacks are that the tyre sidewalls will be lower. This makes the ride quality harsher and the rims more vulnerable to pothole and kerb damage.

I have no advice on a good wheel to choose, unless you go for the standard 18 inch GT "jetfin" rim. In terms of tyres, I'd recommend GoodYear Eagle F1 Asymmetric.

18" jet fins look great. Haven't driven a GT with 16 or 17's so can't comment on comfort. But the GT isn't a car you get for comfortable driving, it's a car you get for great driving and beautiful looks.

Edit: someone's selling a set of jet fins in GTA lounge

For 8*18 I would stay with 225/40/18 with good side protection only to avoid alloys damages by kerbs.
So any tire to be check for this first before purchasing. 235/40 is also alternative.

18s are a must imo - anything smaller makes them look under wheeled.

A few people have got 19's fitted also.. Not original wheels, but you can get away with them..

A bit big for my tastes, but it's an option!

Thanks for all your replies. Mine has 17"s and the "hole" not spoke alloys. Presume previous owner changed them,?
