Chains are usually an issue only in the mountains. Some ares of the State get enough snow to stop railroad trains on occassion and we have passes that are "open" in winter as high as 8000 feet (2438m).

California has three levels of chain requirements and all four wheel drive cars with snow (M&S) tires must still carry chains for at least one axel. If fact all vehicles must carry chains (or device such as spike spiders) in chain control areas. At this instant it is not snowing on I80 in the Sierra and AWD vehicles with snow tires are OK, but they still mus have chains on board.

Go to the CalTrans website for a complete explanation and to http://www.dot.ca.gov/cgi-bin/roads.cgi to check current requirements.

From recent personal experience conditions can go from no chains to full chains very quickly and CalTrans can be an hour or more behind in their updates.

I had bought these same chains for my IS350. They definitely ended up scratching my rims. plus I found they didn't work well. I was attempting to go up Mt Baldy and couldn't make it. It was scary as f^ck because I had to do a U turn on a very narry switch back. Now that I lowered my car I doubt I could fit the chains on.

I am wondering if Thule CS10 is good for ISx50

On my old car that had low profile tires I used chains like yours and the chains scratched up the side of my rims.

Looks like they can do the same to yours according to your pics.

After that I never took a car with low profile tires to the snow. Its not worth it.

Rent a car

Not worth it. Better Safe than sorry?

I agree, I'm so pissed I even tried the chains...definitely should have just rented something for the day.
