Interesting that a 8" rim can only handle a 225 tire. I would have guessed a 245 at least. My old cobra had 8" rims and it had 255/45/17 stock. But then again those low profile tires do look good.
And you are right S2K1 19" are very popular with the 350z folks. I think they look best on that car due to the bigger look over the S2000.

 

It's not that the rim can't handle a bigger tire, it's that the offset pushes the wheels so far out that any wider a tire and it would rub on your fenders or stick out and look tacky. Plus it would kick things up and damage the paint. I haven't had these rims personally, so I do not know, but this is based on my knowledge of this setup. PM RedlineS2K about the tires he's running.
On 350Z's, from what I've heard/seen, 19's are popular on Z's. My dad has one, neighbor has one, bro-in-law has one. They all agree, 19's are "in" on the 350Z. Volk Racing came out with a pamphlet on the 350Z(picked it up at Stillen) and all of their model cars had 19's and there were several 19" wheel options. I think they look perfect for the 350Z because the track model's 18's don't quite fill the wheel wells enough. Drop it a little and put some 19's on it, and it'll look great.

 

Thats the plan, although I do like the look of my Track wheels.

 

well,,,if i recall correctly.,,i think OZ makes a set that is almost identical to this Axis ones..maybeee 19's tho' again..
oh,,and speaking of 350z on 19's....this kid i know has chrome 20s on his.(shit is even slower now for him..and he had an exhaust put on..so its louddd,,but aing going nowhere that quick..hah)

 

Well that is what happens with heavier wheels. That is why I hesitate changing my rims the lightweight rays are nice.

 

If you can afford 19-inch Volks, I say, get 'em. The track wheels are nice, but I feel that there's something missing. It just doesn't strike me as being some really nice wheels, which they are.

 

Well I had the oppurtunity to really drive a S2k today. I must say I was impressed. Dealer is suppose to call me up and offer me a deal for my Z. The manager wanted it for himself. Usually I would say no thanks, however if he can lower my payments by 150bucks per month with nuthing down. That could be mighty tempting. Any thoughts

 

Z is a wonderful car. I was going to buy one myself, but then canceled the order and got an S2K. Nothing beats the top-down fun of an S. It's like a damned motocycle on 4 wheels. Too damn fun!

The other day, I saw a Z with massive, most beautiful 19" wheels on. Oh mama, beautiful! They were deep-dished too. Should've stolen those for my S.

 

What type of wheels were they?
