    That's news to me at least. I wouldn't be surprised, however.

    rurso, what was the exact wheel/tire combo you ended up going with?

    I know that the federal government started mandating vehicle manufacturers to implement some sort of tire pressure monitoring on vehicles after a certain year. Though I'm not sure that they're enforcing it on an individual basis(post manufacturing). So your car is equipped with TPMS system, but is INOP without the sensors which is the operators decision.

    It is fed law that all new vehicles after 2005 have TPMS standard....it is also fed law that no shop mount tires on a car that has TPMS without sensors in the wheels.

    I am not too sure about the legality of an individual owner electing to mount winter wheels on thier car that don't have tpms sensors.

    I all boils down to safety regulations to make sure you are not driving on low pressure.

    I guess it's a grey area type of thing again. Obviously cops don't have xray vision and pull you over just because you didn't have sensors. Unless I guess you get in an accident and they forensically tore down the scene and tracked down the cause to low tire pressure and the tires not having sensors to warn the driver.

    I don't really need sensors as I check my tire pressure every two weeks or so, but I have them anyway because I hate having any warning lights on my gauge panel.

    I don't need them either, but they have come in handy a few times. The ones on my old tC would trip the light if there was a nail in the tire....which is nice to know information even when they are jolding pressure just fine.

    On my rex, they let me know last winter when there was a sudden temp drop outside that made the pressure in the tire drop enough that I was a bit low (29psi) (went from 50's in the day to mid teens by the time I got out of work).

    'course, in both cases above I had to investigate to find why the light came on, but the heads-up is a nice convenience.

    Just a side note Bruce, but if it gets to be an issue you can consider filling the tires with nitrogen. I'm not sure how effective it is when dealing with lower temps, but I know a few serious guys at the track with larger cars do to avoid the (massive) change in pressure with temperature.

    I'm not sure if it works on the lower end of the temp spectrum though. To my understanding, it is the water vapor in the tire that turns to steam and causes issues when hot. By heating your tires up to turn the moisture into steam, purging all of the air (and now steam), and filling with nitrogen, you can eliminate most of the hot pressure changes.

    It's way too much work for me... plus I left my nitrogen compressor next to my cable stretcher in a past life time. The option is there though in the future.

    Right....my understanding is that nitrogen takes much higher pressure to compress than normal air does, and does not expand the same as it heats. Additionally, nitrogen molecules are larger making pressure loss through reverse osmosis far less than normal air....

    These two properties together keep pressure more consistent as the tires heat and cool in addition to keeping proper pressure for longer periods of time (biweekly pressure checks are not as needed)


    edit..... Oh, and btw, Costco does nitrogen tire fills in their tire center, so if you have a membership they can fill you up with nitrogen incase anyone is interested

    That's aside from the water vapor issue I had read about I believe, but valid nonetheless.

    The last book I read actually recommended deflating you tires and covering them in garbage bags when you take them off. I will probably do that for whats left of my RE-11s for next year. Worth a go I figure.

    I only skimmed the last couple of pages, but in case it hasn't been said - winter performance tires are a great option in many areas. I have direct experience with them vs. several sets of A/S on my WRX and they perform significantly better in snow than all seasons and also perform better in dry or wet cold conditions.

    I sort of agree that A/S are adequate and not a real safety issue if you drive safely in areas with reasonable road service (plows) and not a ton of huge hills. I could see preferring them to a real serious snow winter tire for a significant portion of the winter in many areas that get the occasional snow and where you aren't often making actual tracks for yourself through anything over a couple inches. That being said, I'd only do them in a second set in rotation with real summer tires, because I don't think A/S compare to a real good set of summers in any way, shape, or form. And then, since you have two sets anyway, winter performance is the obviously better choice over A/S.

You should see a gain in cold weather cornering traction with the WS3Ds along the lines I stated earlier (3-5+MPH). Obviously, in snowy conditions, you're not really going to be pushing the limits, but it will certainly have better snow traction than whatever A/S tire you would choose to throw at it.

    I don't see how a cop could ever enforce a law requiring TPMS sensors. Are they going to pull the tires off the rim to see if you have sensors? There's no other way to tell...
