Tire/lift laws

depends on what type of inspection you require to be able to bring your jeep here, most places are lax on the rules, in fact many if not all vehicles would likely fail an inspection if the mechanic wanted to pick it apart, for example the size tire that is supposed to be in it which is posted on the doors has to match all the tires are the vehicle, the front and rear axles must have matching tires(meaning the front 2 match and the the back can be different tread of similar patterns) bull i know ive read the laws because i want to mod my jeep and not get in trouble, front axles must have swaybar links, shocks can not leak, all equipped lighting on the outside must work, brake lights, turn signals(most ignore fogs as many add what they want, battery must have a tie down that is part of the vehicle(not a bungy cord or ratchet strap) bunch of little stuff, look up a few shops and hope you don't move to allegany county where they have strict emissions testing or the th philly area.

I believe the widest tires can legally stick out is no more than 2 inches, and the bumper or lights(can't remember off the top of my head) cant be more than 52 inches from the ground(i want to say the bottom of the bumper though).
good luck look me up if your in western pa sometime

The fenders have to cover the width of the tread. The maximum bumper height (height of the lowest horizontal part of it) depends on the weight of the vehicle, up to 30 inches. As far as lights go it's always - if it's there it has to work. Fog/ driving lights have limitations and have to shut off when the high beams turn on... I believe you're allowed one pair, dot approved, and any additional need to be covered when on a public road. The headlights have to be properly aimed but I've never seen a shop bother to check them. Tires can be mismatched brand and tread but must be the same size across the axle and can't be mixed with bias ply and radial on the same axle. The shop is required to pull a tire off each axle and check brake lining thickness, rotor run-out, rotor thickness, etc. They're supposed to check wheel bearings, ball-joints, tie-rods, make a visual inspection of the emissions parts, check for exhaust and fluid leaks. There can't be any holes in the body (fumes), fuel lines aren't allowed in the passenger compartment. Sharp/ jagged edges on the body aren't allowed (like after a wreck that could cut someone). The exhaust has to exit to the outside of the body, no dumping underneath. No parts are allowed below the 'scrub line'. The seatbelts have to work too. There's more but that's a good start.

The law doesn't seem to have anything to do with lifted vehicles and more todo with vehicles that would have a registration class change.(v8 swap into a 6cyl, gas to diesel, removing axles and repairing flood vehicles). Hopefully the GRAY area becomes clearer and shops don't go full retard. I've been looking into what I have todo to get my jeep to pass PA inspection since i'll be moving there in august. I've got a lot todo starting with flares
