hi sockeye.
I have the same problem, went from 20's to a set of wrangler 18's with the falken wildpeak on, still have to sort out a spare after about 18 months
, good to know it will fit in the well.

my fuel consumption went up by about 1ltr per 100k's and made the speedo about 3-5kmh over so cant complain too much and they are wearing pretty good and even.
