Système de surveillance de la pression des pneus

[white328]

Je viens d'acheter ca : http://www.canadiantire.ca/browse/product_detail.jsp?FOLDER%3C%3Efolder_id=1408474396676731&bmUID=1230074063130&bmLocale=fr_CA&PRODUCT%3C%3Eprd_id=845524443298019&assortment=primary&fromSearch=true

Je sais pas si c'est très précis ou utile, ou bien c'est juste un gadjet que je devrais retourner au pc parce que c'est bon rien. Je pensais que ca pourrai être utile pour voir si la pression dans mes pneus bouge beaucoup en conduite sportive ou bien sur la piste.

you might need to re balance the tires after you have installed those because the senders weigh a few oz's

I hear these sensors are not that reliable, especially in winter. Is it really necessary to purchase a new set of 4 when installing a new set of rims/tires? I recently checked on Tire Rack's site for a set of winter wheels for my wife's car. The pressure sensors are over $90 US each for the Honda CRV, almost like paying double for the tires.

I thought the idea of using a TPMS system was mainly support cars equipped with run-flat tires. Now it seems they are using them with most new vehicles.

Theoretically it is only necessary when using run-flat tires. It practice the government lets any shithead operate a 4000-5000 lbs vehicle with up to 120 kg of highly explosive liquid in it. So the said shithead never checks his/her tire pressures leading to low tire pressures and spectacular blowouts at highway speeds with the ensuing rollover and suing of Firestone and Ford and whatnot.

So the US government mandated the system on all new cars now as they realized that any attempt to outlaw shitheads will eliminate their basis of power. Canada does not require the system but as most cars are made for the US market we get to have the system here, too.

For street driving the system is pretty good, especially when it is easy to reset from inside the car. On the track it goes all sorts of crazy and is best disabled. Owners of 997 GT3s get mostly annoyed by warning beeps but the C6 Z06 would actually go into limp mode annoying the owner even more.

They are reliable. They start having problems when loser tire installers break the sensors or don't reset the system properly. At work we have a very nice 600$ tool to reset the systems properly... The tires have to be bone dry when installed also.. the inside. I've also seen people scrap sensors when they use a can of fix a flat...

Sensors for a GM cost around 35$ each and I think around 40$ each at Honda. The prices have really come down. They are even cheaper jobber solutions.

Ford has the worst system known the man kind.... It wraps around the rim and is very very very very to break when installing tires.

Checking tire psi to most is like checking oil.. it's never done until some light pops up on the dash. 99% of drivers need idiot lights to tell them that they are idiots.

They should standardize the pressure sensors so that all cars can use the same sensors. This would certainly help to drive down the price of the sensors even more.
