I agree the government sucks, did everyone read the cover page for off-road.com?
Here is a copy of the "lift law" and a example for a TJ I have off another list:
540 CMR 6.00 says....
The maximum mechanical lift for four wheel drive vehicles shall be calculated
by multiplying the wheelbase times the wheel track, and dividing the product
by a safety factor of 2200. The outside diameter of the largest tire size available from the original manufacturer as standard or optional equipment for the particular motor vehicle may also be increased up to an amount equal to maximum mechanical lift calculated.
The maximum combined mechanical and tire lift shall be no greater than the sum
of the maximum mechanical lift and increased tire size calculated for the
particular vehicle.
So for my '97 TJ
93.4" WB x 58" WT divided by 2200 = 2.45" maximumlift
and 2.45" tire diameter larger than stock or optional (30" for TJ)
equals maximum tire size of 32.45"
That means my 3" lift and 33" tires are technically illegal.
I am concerned about this also and my plan is to go SOA and then SUA for the inspection with stock size street tires because there is another law in the
link above that states no mud tires will pass either. Can you believe this?
This whole inspection thing here is MA has just surprised alot of us out here.
Here is another link for the law regarding tires outside fender wells.
