Can someone enlighten me as to what TPMS is, why it's important, and whether I need to buy one before I put my snow tires on my FR-S?

TPMS stands for Tire Pressure Monitoring System. They're probably talking about recalibrating it for different tires. If you can point me to that thread I can probably decipher it for you

Well, what you for sure don't want to do is rev it when the engine's still cold. What's ideal for the car is to drive off at low RPMs and generally drive moderately until the engine warms up. But if it's too miserable inside the cold car in winter, then it can be considered a reasonable trade-off to idle it until you start getting warm air coming out the ventilation ducts.

I would have seen if the dealer would have taken a trade-in for her. She works hard and bakes a mean casserole; mops floors too! I'm only kidding but I slapped my head when I read that.

Now here's my noob question. It's pretty general and probably applies to most cars-

Some people say it's better to warm your car up in the winter by turning it on and letting it run for a few minutes. Some say that it is okay and even better to begin driving immediately upon cold start, as long as you drive it very lightly in low RPMs to start out with.

What do you think is the best way to warm up your car in the morning?

IDK if anyone else has noticed, but when I turn on my FRS, it starts at 2500 rpms then slowly works itself down to 1200. then it changes its noise to a lower one, goes up to 1500 and goes down to 800 rpms in a few seconds. That's when I know the car is warmed up. It takes about 30 seconds on daytime California and about a minute 30 during nighttime. If i keep it any longer the Idle Engine Noise comes on haha.

Thanks! The thread is here: http://www.ft86club.com/forums/showt...t=20301&page=6

The discussion about TPMS is only on the last 2 pages or so.

Soooo, my FR-S stock wheels already have this sensor? And I'm technically supposed to buy a new one to go with every set of wheels I buy?

The deal with warming it up in winter is for the creature comforts of the human occupants, so yeah, it's a trade-off.

wait 10 seconds for "pressure in the boat" THEN drive off slowly keeping revs down until engine reaches operating temperature.

no idling! get "oil pressure" then drive off! your car will warm faster under load,as opposed to just sitting there idling.parts will wear more rapidly in a ''cold" engine at idle!

You can go without TPMS however your TPMS warning light will pop up without them. This can be fixed by going to the dealer and having them remove it from your computer. You don't have to buy a new set for every wheel you can remove the current set and move them to new wheels as well.



Engine wear during a "cold" start has two main components to it. First is the temperature. As the engine heats up different metals inside the engine expand at different rates causing wear. This includes compression rings, pistons, engine block, and valves. The second component is oil. As the engine sits the oil slides off the cylinder wall down into the block. This means that there is a thinner layer of oil on a "cold" start meaning more wear. This gets fixed when the piston dips itself more and more times into the motor oil. So the type of oil that you use can also be a big factor in engine wear. It's best to pick the stickiest type of oil you can find.

Thanks for adding that! A good way to make it happen is to start the engine, *then* put on your seat belt, check mirror adjustment, adjust windows, select music etc, *then* drive off. I do it that way, but I had forgotten why

for me its usually start car... wait for wife to actually get in car then go

Well that's what the guys in the "Snow Tires" thread are saying (actually it's one sensor for each wheel plus programming/calibrating by the dealer). But then we learn that:

This would be my personal preference - either skip it altogether or reuse the current ones. Either way I prefer to keep an eye on tire pressure myself instead of relying on sensors which can fail - but that might be because I go way back to before there were sensors for everything and early ones were often faulty :P

With the caveat that you don't want it so sticky that it turns to molasses in cold weather, making cold starts hard all over again.

My Noob Question would be related to paint.

Is Opticoat the same as Xzillon?

[Synack]

What you guys don't all have turbos and floor it the second you turn your car on from a cold-start? Get with the times!

[travace]

how does one know what tire/rim sizes will fit their car and an explanation of what all the numbers and letters mean.

I usually let it warm up enough to see the temperature needle move up to the first bar before I slowly drive off.

+1.

I will wait until the temp gauge is not bottomed out and has risen to the first bar as well.
