Eh, most 37's aren't actually 37's anyway. You can look at their actual size charts and alot are 1/2in shorter. Add weight and lower tire pressure , wahhlah, your 37's are now 35's
Makes me feel better about runnin 37's on my d-30

it all depends on rim width, weight and air pressure. i have found that most bfg's will run about 1.5" less then stated size once on the vehicel. my 35 km2's messure approximatly 33.5 after mounted up. i wish i would have went 37's now.

I think you missed the previous post. My 37" Cooper stt are 37" when not mounted. If I used a 10" rim and ran 50-60 psi I would have it stand at 37" mounted. Since I use a 7.5" rim on a 12.5" tire and run 26 psi... I get 35.80" mounted. I'm pretty sure that if pitbulls stand at 37" unmounted... They would be less then 36" mounted on my setup.

On that 8 inch rim you are squeezing the hell out of that tire. That make the tire stand taller when on tht rim. Put the same tires on the correct rim and you will measure a shorter overall height.

or is whats happening is you are squeezing so much you lose some side wall height?
