Okay, heres what I'm after. Data only, discussion can be had in other threads:) This is in the SRT section becuase AFAIK, we are the only ones that can read individual tire pressures on the fly.

Any 5.7 owner that wants to participate by pulling over and actually taking readings with a gauge, go right ahead, but I suspect that wont be many.

Followiing is data format, please follow. Suggestions to include relevant data I've forgotten are welcomed

Cold (overnight sit with no driving) temp and pressure

Readings from a few points during your commute/trip, with mileage and air temp as reported by the car, if there are changes. A short desription of the driving route itself, maybe a Google maps thing showing your route.

Heres mine, from this AM.


Start 06:20AM Temp: 55F

Pressures

LF.......RF.....LR.....RR
28......30.....29.....29

Waypoint #1 = .9 miles

LF.......RF.....LR.....RR
29......29.....29.....29

Finish 6:55 Temp 55F 14.3 miles

LF.......RF.....LR.....RR
31......31.....32.....31

Speeds varied from 35-55 during this trip, with the last section being pretty much steady state 45. I'll be doing a run at lunch time, when temps are about 20 degrees higher, and see what happens.

Do you want to include track observations with F1's in this thread?

Tonight ....

Parked at a restaurant for over two hours ... mid 40's here tonight ..

LF ... 30
LR ... 30
RF ... 31
RR ... 31

Started the 30 mile drive home, all 4 lane limited acess highway ... Within moments all 4 tires registered 31 psi ...

Started cruising around 75-80 MPH .. tires all climbed to 32 psi after about 10 minutes ... then all reached 33 psi 10 minutes later and stayed there for the duration ..

BTW, I find that my tires, according to my dash read-out run about a pound or so lower than my gauge, most times...

Okay, did a 12 hour run from MA to MD today, took some info.



Start 8 AM Temp: 37F

Pressures

LF.......RF.....LR.....RR
31......30.....31.....31

Waypoint #1 = 50 miles (speeds averaged about 80-90, all free way on the MA Pike and 84 south into CT)

Temp: 50 degrees

LF.......RF.....LR.....RR
37......35.....36.....36


Waypoint 2 200 miles, speeds 75-85, into NYC, and the Cross Bronx Expressway

Temp, 60 degrees

LF.......RF.....LR.....RR
37......36.....37.....36


After that, it was constant rain, which dropped pressures down to the 35-36 range.
