Scrub Line
Imagine your car-any car-sitting on the street without any tires. The wheels are still there, just without the rubber. Is anything touching the ground? Suspension parts, any brackets, exhaust system, fuel tank, transmission, or motor even? If so, they are below what is called the scrub line, and while you may not worry too much if those massive 6-inch lowering blocks meant the nuts on the U-bolts are now halfway down the sidewall of your rear tire, you'll be in for a nasty surprise if you get a flat on that tire at speed. Those U-bolts will make a nice gouge in the blacktop, and you'll be fighting to stay in control of the car ... if you're lucky. You'll more likely be in the ditch or facing oncoming traffic. Tall tires don't help either, but ensure no part of your undercarriage hangs down below an imaginary line drawn between the bottom of all four rims. In fact, an inch of clearance would be a good idea.
