Is this mod legal?

I think they mean that it cannot project radially past the tread, that is, it can't come in contact with the road surface. So I would say no, trim rings are not illegal.

 

If the Tread width is larger than the Rim width, as it is in most tires, you have no problem at all with those trim rings.

Look at this cross section, the tread has a greenish tint and is much wider than the bead that attaches to the wheel.

 

Trim rings aren't tires. Wheels aren't tires. The only things that are tires are tires (those black rubber things that they replace when they wear out).

I don't think it will be an issue. If you do happen to get cited for it, I bet it's an easy ticket to fight (for the reasons I gave).

 

Right. They don't want you to have any metal or wood in contact with the ground (with the exception of the things they've listed), like spikes for ice racing, bolts, nails, paddles, etc., because they would tear up the road surface.

 

If these are Plastic Chrome plated like the factory trim, it's not covered in the wording...

"block, stud, flange, cleat, ridge, bead, or any other protuberance of metal or wood that projects beyond the tread of the traction surface of the tire."

Don't see the word Plastic in there.

 

periphery (plural peripheries)

1. The outside boundary, parts or surface of something. The suburbs are a city's periphery

If you look at this in the context of the exceptions listed in the V.C. (i.e. the exceptions tell what types of studded tires can be used in Calif, etc.) it seems clear to me that they are talking about the outer diameter of the tread, aka the periphery.

 

I really like the tire shedder wheels..


But I suppose the extra weight would shred the MPG!!!

 

I don't think those are legal, but I don't know which specific V.C. would apply. Maybe the Ben Hur subsection? :madgrin:

 

I am guessing you live in California, this will help you find a local office.

those rings have pictures of rims they fit and don't fit... a prius rim is on the doesn't fit list.

IF it did fit.. it wouldn't matter in CA. they allow spinner rims here... (because they don't exceed the sidewall of the tires)

 

I'm an officer of law and I can tell you this is refering to studded tyres and chains or wooden blocks strapped to the wheel for traction in mud. It refers to the traction surface of the tyre, so nothing on the tyre should be metal or wood and nothing on the wheel should be able to contact the ground apart from the tyre.
