It wasn't a question of opinion....he just wants the truth.
Over here in WA, if u ask the cops they'll tell u 1 thing but then if u ask dep't of transport, they'll give u another story.......it sucks but I think as long as your speedo is recalibrated to suit & there is clearance under the guards, u r pretty safe. I've never heard of anyone over here getting done for tyre size but they do tend to pick on susp height sometimes.
The legal requirement should be able to be veiwed on your state's transport dep't website. Happy hunting.
I hope that is unbiased enuf not to stir the pot
