Hi All,

I currently have a 53 Plate TD5 XS Disco 2with 18 inch Hurricane wheels and 255/55/18 Tyres.
For Winter I have from a previous car a virtually brand new set of 245/70/16 General Grabber AT2 Tyres and have purchased a set of 2nd hand Disco 2 16 inch Alloy wheels.
My question is will they fit without any mods, some seem to say yes, some say no??
Will the wheel nuts I currently have be OK to use or should I use the set that were included with the 16" wheels. (not 100% sure they are the original ones!!)
Also if I get a flat, would it be OK to use my current 18" spare or would that not be an option due to very slight diameter difference.

I have checked on a tire calculator site below and they are very close:

Any help appreciated.
