Yes... don't worry about the offset for snows. I would pick wheels with the 30 offset.

But if I go with 35 it won't be a bad thing right? The only style within what I'm willing to pay is 35. 5 mm can't make that much difference right?

 

Don't sweat the small stuff. It won't make any difference when mounting 225mm wide tires. It's not even a quarter of an inch.

thanks for all the info, guys. Im glad I do some searching!
say if I want to keep the 18 stock rims on my 03 Z, what is a good set of winter tire for me?

 

Tirerack.com is where you can check prices and compare tires. There are very good snows for your 18” wheels. But consider this: For the price it costs to un-mount your summer tires and mount winter tires on your 18” wheels (and doing this twice during a year), you can buy inexpensive 17” wheels on which you mount less costly snow tires. And, snow tires are superior on 17” wheels. The idea is having two sets of wheels and tires (summer and winter). It costs less going this route.

thank you, spike!
since I dont have much money to do anything right now. Is it ok for me to drive on snow at 20mph (we are in Kansas and it snow SOMETIMES only, not always)
But next year I will invest on a set of 17 and snow tires right away!
btw, I bought my car USED so dont have owner manual. Whats the lug pattern on the z?

 

^^ If you're on tight budget, maybe it is wiser to invest in some all-season tires that you drive year around. Since it doesn't get that cold in Kansas, and you don't get much snow; that would be an economical solution for your 18" wheels. You wouldn't need to swap out seasonal tires. You're in a climate zone that begs for all-season tires.
