I have answered this query many times if only I had a £1 for everytime.
the spare is a 90 profile on a 16" rim which means it has the same rolling distance as your standard alloys and tyres. the correct fitment for all jukes is 135/90x16 and 145 is slightly wider a 125 thinner they all fit they are correct size and moreover they are the size supplied by Nissan on all 4x4 Jukes and what you will be given if you buy one from the dealer.
