...and if so, any ideas on how hard it is to adjust the system and to what it is set to from the factory?

Um.. TPMS? I must not be following too closely..??

 

Sorry ... TPMS = Tire Pressure Monitoring System

AFAIK, it's going to be a requirement for all new cars in the near future, but I don't think it's mandatory yet. My R32 and Forester have it. While it's a nice feature to have, it:
a.) adds cost when buying new tires if you don't want to yank your TPMS sensors out of your old set
b.) becomes a PITA if you go with tires that run at a lower pressure than what the system has been set to (i.e. factory tires)

Well considering all the 08 Lancers have it, I'm 99.99% sure every Evo X trim will have it too.

Its been a while since mine went off but I think it was going off at about 27psi. The manual recommends the tires to be at 32psi cold. Not sure what the Evo X's tires are recommended at though.

There'll be a little bit of extra "bull****" if you ever do switch wheels, cause you'll have to transfer the sensor's over. But I highly doubt weight is going to be an issue. These are tiny eraser-sized things we're talking abut.

 

All passenger cars, light trucks and vans (Gross weight less than 10,000 pounds) must be equipped with a TPMS starting in model year 2008.

Actually no, they're quite a bit larger than a pencil eraser. Google it, you can find pictures of the various types. And you can buy sensors with your new wheels so that you don't have to unmount the tire and swap the sensors every time you want to swap wheels .

 

Wow.. I didnt know this.. I wonder why? Is DHSMV blaming low pressure for accidents or soomething?

 

Does anyone know what the recommended and max pressure ratings are for the new Advans that come with the X?

I believe we all have the wonderful world of SUVs to blame for this ... specifically the uber-top heavy pieces of crap like the Navigator, Explorer, etc...

Err I own a 2008 Lancer which probably has the same sensors that the Evo X will use and I've swapped them out when I changed wheels. So I think I will use my firsthand experience rather than a Google link. Thanks anyway though. But I guess with those Subaru's every little gram saved helps right...

Sure you can buy new sensor's from the dealer or aftermarket if you want to spend upwards of $100 plus another $60 or so to get them programmed to your car. Not sure how many times you swap your wheels but I don't imagine its going to be a daily excercise for most people.

 

^ For those of us who road race, swapping wheels is almost a weekly event.

Then I guess you'll just have to buy a new set from your dealer or aftermarket and have them programmed. Unless you can find someone to disable the constant warning for you

 

Partially. More specifically you have millions of drivers who never check their tire pressure and drive around with severely underinflated tires. Underinflated tires create all sorts of problems, including reduced fuel mileage, increased stopping distances, poor handling, and in top heavy vehicles, a slight increase in probability of rollover. In severe underinflation (i.e. just enough to keep the tire bead on the rim) the chance of blowout goes up exponentially, which is why TPMSs are being mandated. Very few people know how to deal with a blowout because it's such an infrequent occurrence.

TPMS is a good thing. Just a pain in the *** for drivers who actually *do* monitor their vehicles.

 

There are also drivers who overinflated their tires! One time I was at the gas station waiting for this korean couple to finish inflating their tires. I watched them spending about 5 - 6 minutes per tire without actually checking the tire pressure
