question about tire pressure monitor
#1
#2
On mine it says (36) under each, which is the recommended tire pressure. I am usually running a bit higher than that (39-40).

That might be the fastest highjack in internet history.
Guys, my question wasn't about the correct tire pressure. I'd like to know why, UNDER each of the 4 numbers indicating the current pressure for each tire, there are 3 periods in parentheses, like this: (...)
It's not explained in the manual.
Thanks.

Frenchy, drive the car for a few miles and see if the parens get populated with some numbers.

You have to turn ignition on without starting the engine. Use the "ok" button and directional buttons to the left on the steering wheel to manouver in the display menu. I don't remember exactly what it is called, but it is something like "car information" menu and then "tire pressure".

Then: push the up or down arrow until you get to "vehicle information" screen between the gauges. push ok button again, and then scroll down to "tire pressure" and hit the ok button again.
Hint: the left arrow reverts you to the previous screen.

New theory: All the my14 and my15 models are set at 36. All the my16 and my17 models are set at 37.
New mystery: In the "vehicle info" screen, there is a "tire info" option (not talking about "tire pressure" option). In the "tire info" option you can select either display units or "recommended tire pressures".
Selecting the latter produces the following results:
................. Front ...... Rear
slow speed ... 37 ......... 37
normal ......... 45 ......... 41
The "normal" values seem to me to be appropriate values for roadtrack applications, but there has been a lot of discussion by some that higher values are inappropriate for new tire technology. I refrained from argumentation as I had no definitive proof to the contrary, but this seems to support my thinking that tire pressures need to be elevated for high speed handling purposes.

I see that in the F-type owners handbook from 2013 it says:
Tyre pressures - up to 250 km/h (155 mph): Front 36 psi / rear 36 psi (20")
Tyre pressures - over 250 km/h (155 mph): Front 41 psi / rear 41 psi (20")
It also says: "Vehicles supplied with 20 inch wheels also have a speed based TPMS system. If the vehicle is required to travel at speeds over 250 km/h,the tyre pressures should be raised. Failure to do this may cause the warning message TYRE PRESSURE LOW FOR SPEED to be displayed in the Message centre.
