Heh, welcome to Massachusetts where lift laws really suck and there's no cheats around them.
Here it's not bumper/light height. Here they measure rocker panel height. There's two different laws on the books, one says no more than two inches up or down. But the one that most people follow is a registry formula. It's wheelbase and track width and some other arbitrary number.
Basically our tj on 33's is about 2" over the legal limit but for the most part no one notices.
On a full size truck as long as you don go crazy on lift height you can get away with 35's. Anything after that you're pushing it. There's a reason you don't see many huge trucks around here.
I've known two people who regularly drove trucks on 38's. One got lucky and got away with it. The other got his balls busted so bad he sold the truck to a friend who then got his balls busted so bad he took lift out and ran it on 35's and never got bothered again.
