The laws have been on the books for some time, but the DOT sent out a ‘clarification’ in a June 2016 bulletin.
TIRE STRETCHING The act of installing a smaller tire on a larger wheel commonly known as tire stretching, may be unsafe in regards to safe operation of the vehicle. When inspecting a vehicle on which tire stretching is evident, inspectors should be vigilant to ensure the ‘reject if’ criteria listed in 175.80 is followed. Possible ‘reject if’ criteria that could be applied are:
• 175.80(b) Internal Inspection;(v) the front wheels can’t be turned to the full right or left position without binding or interference, (vii) the number of turns of the steering wheel from a straight ahead tire position to the position to the top right is not equal to the number of turns to the top left stop within a tolerance of ¼ turn.
• 175.80(e) Beneath the Vehicle Inspection; (ix) A tire’s tread extends beyond the outer edge of the wheel housing inclusive of fender flares; (xxii) A tire is smaller than the manufacturer’s recommended minimum size or below the manufacturer’s recommended load rating, (2) (iv) The steering stops allow the tire to rub on the frame or chassis parts; (v) The front wheels are incapable of being turned to the right and left steering stops without binding or interference.
Note: To determine if a tire is “smaller than the manufacturer’s recommended minimum size”, you will need to determine if the overall diameter of the tire is smaller than the recommended minimum size. To accomplish this, the inspector can utilize resources such as the tire manufacturer or tire retailer websites, web-based tire diameter calculators, tire diameter smart phone applications, or printed tire specification charts which are available from parts stores and tool suppliers.
• 175.80(f) Road Test; There is a malfunction of the braking or steering mechanism, particular shimmy, wander, pull or other questionable behavior that affects safe operation of the vehicle.

So tires have to be properly fitted to wheels now? Good.

I still think that JZX100 Chaser up top is sexy even with a horrible stance on it.
Just put those wheels at a slight step of negative camber, and a 265 out back like it should be. With a 245 up front. Call it good. I’d drive it til it was junk.
Although I’ve got a special place in my heart for JZX90 Mark 2's and JZX100 Chasers.. Love me a chubby chaser.. (nick name we gave them in Japan..)

There is a lot of anti-big tire in there too. Frankly I think the smaller tire line is a step too far. Load rating? sure. Tire size? why?

this looks like it is for DOT state inspections....... nothing a set of spare rollies can’t get you past......

I always thought that the terrible potholes and failing infrastructure of Pennsylvania roads would sort of self-police any stanced cars that were foolish enough to reside in the keystone state.

This. As worded, those regulations render many snow tires illegal as well.

They ought to add a provision talking about under sized tires in relation to original wheel sizes, or some such thing that prevents having tires that are too small for the wheel they are mounted on rather than just small tires.

It’s interesting how some states have inspections and take enforcement of DOT regulation/safety standards while California has crazy levels of Smog regulation and no inspection whatsoever...

Not really, as the way to check the size only specifically mentions diameter, and you should get a snow tire that’s smaller in width, but still has about the same circumference, to avoid speedo errors.
The initial paragraph does mention smaller tires in the sense of width, but there’s nothing in there that explicitly forbids that.
Additionally, some/most manufacturers put recommended winter tire sizes in the manual, which are often both smaller and with a lower speed rating.

unsafe in regards to safe operation
Only at a large bureaucracy could a phrase like this make it into a final version. OH, thank you for clarifying that you meant “unsafe” in regards to “safety” as opposed to “unsafe” in regards to “not in a safe, vault, or other secure facility.” Or, worse yet, one could be open to assume “unsafe” in regards to countless other dangers such as STDs, meteors, UVA (or even UVB!) rays, or grizzly bear attacks.
