240 Wheel Options

You can also use Lotus Excel alloys as I did to good effect with 225/50/15 tyres, these can be found for next to nothing and are the perfect offset and pcd for a Z, my personal preference though would be 17" rims with 225/45 fronts and 255/40 rears these will fit with a little manipulation of the arches where they meet the cills, these will be seriously grippy and the ride will not be that bad either (depending on spring rates) though they will not please the purists in search of the classic high profile rubber look.
At the end of the day it is your car and you should go with whatever you are happy with, it might be an idea to go to a wheel specialist and get them to hold up a number of different size wheels next to your car to get an idea of diameter / style, remember that tyre profile has a serious effect on the sidewall stiffness and with careful spring / damper / profile matching you will greatly increase your steering response and feel as well as roll and tyre flex resistance. remember to try and keep your rolling diameter as close to stock as poss otherwise your gearing will change for better or worse and your speedo will be further out than normal or might even become more accurate................have I added to the confusion

BTW 19x7 wheels will fit a standard Z with as wide as 225/35 or 235/30 (rear) tyres and still be less than the rolling diameter of a late 260z with 195/14 tyres which I assume are 80 profile at 667.6mm, but the ride...........what ride.......you will feel every rizzla you run over

Tire/Wheel Sizes

On a Z with a noncoil-over set-up you can easily run 215 or 225X50X15s on either 6.5 or 7 inch rims. Good springs will keep the tires from hitting the inner wheelwell. As to spare tire issues, the 215 will fit but the 225 sits proud back there. I can get all four 215X50X15 race tires in the back of my 240 but 225 won't fit. The race tires now sit on panasports (minilites).

A good idea is to mount the tire/wheel combo and jack it up through the suspension travel and see if it rubs or hits any where. Borrow a wheel from someone else's car. You also get to see what it looks like. Or if you're handy with the computer a little photoshop work will do the trick.
 
Sam, Baddog has just reminded me of something very important, the wheel and tyre combinations I was talking of require the use of smaller diameter Leda springs with adjustable spring platforms, this skipped my mind cos when we were all Z crazy young boys, Leda suspension was a must have and everybody I knew had it on their cars.
 
Just one Question, is there any way to put 8.5" Wolfies on a 240Z without welding? I just bought two of them and two 7"! I think it was a big mistake and they where used on a 280ZX.
Thanks, Joachim.:S30:
