you have at least one response in the tire/wheel section of the forum...

you need to not buy used 500 dollar wheels for your 35k Z! lol

im not sure many people will have info on tire setup since that is narrower than the factory wheels...

245/40 for front,275/35 for rear.

For winter tires you want to go narrow if you think you'll be driving in the snow.

215/45-19
245/40-19

These sizes would keep you very close to the stock diameter.

Why would you want to go narrow for snow?

Fat tires will "float" on the surface, especially in deep snow. Narrower tires give better traction in loose snow. Ideally you might run 225's all around on 18" wheels, if you could find a set that would fit. I think 235/40-18's might work on the base Z wheels?

The other key issues are tread design and rubber composition.

For tread design, there are two issues: ice performance and snow performance. For ice performance, you want lots of little "edges" in the tread to help provide traction. Micro-siping of winter tires and multi-cell treads are attempts to provide this. Or you could just go for studs! For snow performance, snow grips better on snow than rubber does, so modern snow tires are designed to pack in and hold a bit of snow in the tread. Older designs (mud tires) try to have open patterns that throw the mud and snow out and keep the tread clear.

Most non-winter tires get hard when it gets below about 40 degrees F. They provide very little traction even on dry roads in the winter (in the northern climates).

I tried a bit of ice-racing once. A bunch of guys there used to gin up their own tread batches, including embedding walnut shells in the tread which created lots of pockets for better grip. And in the studded classes, they had incredible stud arrays that might be classified as deadly weapons. They would throw up huge rooster-tails of frozen snow/ice as they buzzed around the lake. Fun stuff!

Think of wide tires as being sleds.

This is true only when driving on snow. When I lived in Chicago, I drove on actual snow less than 5% of the winter. The roads are usually dry, only wet or light slush coating. The stock width is best. If you live in the country and drive on snow covered roads, then go narrow. If you live in a urban place that uses salt, stick with the wider tire.

The rubber compound and sharp edges of the tread were more than fine for the few times I was actually driving on loose snow.

Just my 2 cents
