Re: question for you wk owners.
You "should" be fine with that size. Most can get away with 255/75/17 which would be a hair taller and maybe a bit wider(mm or so..). I don't think you'll have an issue. Technically the two sizes I listed ate identical bit with the bigger rim I believe you'll gain a bit more leeway.
