Looking into new tires in the next day or two and I want something a little different than that stock 265/45/18 rears and 245/45/18 fronts that are currently on my 18" touring wheels. Ive been reading a little but have come to no conclusion. Im planning on getting the BFG KDW2s and have herd people running a wide range of tire sizes for better performance and would just like some general input on the setup you have or have had experiance with. Pros and Cons of size setups would be helpfull too.
This is the range ive seen according to this thread: https://my350z.com/forum/wheels-and-tires/231823-03-track-model-wheel-question.html And i could be wrong but I thought that the Track and Touring wheels are the same dimension...
Sizes:
245/40 all around
245/40 front 255/40 rear
245/40 front 265/40 rear
255/40 front 265/40 rear

245/40 front 255/40 rear ---- Best application in this list
245/40 front 265/40 rear ---- Rears too wide
255/40 front 265/40 rear ---- Too wide on stock wheels. Not safe.

I recommend OEM width + 20mm. No more. The rear tires should be 10mm taller than the front.

Any tire shop who is careless enough to put 265s on your stock rears is asking to get sued when you loose control and wreck your car. Oversize tires are not supported properly because the sidewalls of the tires are not re-enforced enough against wheel. If you corner hard enough you could roll the tire off the bead, but most likely you'll just loose control.

On the next set I will be going with a 265/40 and I suspect it will be just about perfect. This is with the BFG TA\KD by the way...
and yet more confusion...

Well since you are having so much doubt regarding our advice, and I'm really not trying to be an a$$ about this, your best bet is just go and get whatever you want. If you want to go with 275s or whatever and the tire shop is actually stupid enough to install them on your stock wheels, then go with it. Run around town for awhile and see how your back end reacts. Once you realize what it does to your car, return them under the 30 day ride guarantee (most tire stores have this policy), then put the correct sizing back on. Problem solved.

I didn't say you were an a$$. I was covering myself since people around here tend to have a trigger finger for flaming and a nose for the negative.
