Det ser ud til at du skal "trimme" kanter med 235/85-16.
Tillader mig at citere fra

235/70-16: Stock tire size.
205/80-16: Stock size in many other countries. same height as 235/70-16.
255/65-16: same height as stock
225/75-16: little taller than stock
245/70-16: little taller and wider than the stock size. reportedly, no need for lift, just minor trimming to fit those tires.
245/75-16: popular size for OME suspension lifted vehicles. require slight trimming on the rear wheel well fender, and may also call for adjustment on the steering bumpstops.
215/85-16: same height as 245/75-16. but narrower. seems to be preferred for the snow and mud.
265/70-16: about as tall as 245/75-16, but wider. will require more trimming and steering bump stops adjustments along with taller bump stops over the rear axle.
265/75-16: almost 32" tall. Same as stock NAS D90 tires. Will require even more trimming.
235/85-16: same height as 265/75-16 but narrower. And seems to be the most popular size with OME lift.
255/85-16: about 33" tall...very few people have fitted this size. Lots of butchering for this one.
285/75-16: about 33" also... but very very wide.
