The steelie spare is not the same as the DX rim afaik, the DX rims are 16x6, the spare on the ST-R is a 16x7, get another 3 and you have a set of genuine Nissan Sunnys. Wonder what Nissan actually charge for the steel wheels, might have to enquire about that.
well a 265x75 should measure around 805 - 815 mm in dia.
Grab a tape measure and climb under.
My guess is that they would without a problem as there is a fair amount of space there.
how do you take the spare wheel off the car? im not used to all this 4wd stuff... whats with the chain hanging down? does that release it or something?
On fitting the 265/75R16 under the tub. when I changed on my 4wd wheels this time I tired again and it fitted this time. Just needed to make sure I pushed it away from the exhaust when I was winding it up.
