Pump your tyres up and get Free Fuel (I am an idiot)

[DaiRees]

Or the TG where they drove the 3 Cars 750 miles to Blackpool to switch the Illuminations on... That Jag was amazing

[Doggy]

And throw out all extra weight - tools, building supplies, cows...

Dogs?
And switch off heated seats/rear window, air con, radio....and the fogging foglights

Now lets see, 613.9m / (67.14l / 4.54) = 41.51 mpg or well overdue for checking pressures

My steering's lighter now

[mjb]

If I put 50psi in all the tyres do you think my mpg will go up

Lots, but you'll also pay for 6 sets of tyres a year

[Doggy]

Finally checked mine for the first time since I bought it in October
Looked at the sticker, says 2.3 bar F + R lightly loaded / 2.3 F 3.2 R fully loaded....
Gets to garage - posh automatic pump only works in psi
Varied between 24 & 27
So I standing in the snow trying to remember 1bar's about 14.5 psi so 2.3 = about 36??
Vaguely remembered Dai saying more in the rears & suspected the pump a bit so I compromised on 35 F / 36 R
Suspension seems a bit firmer, streering's a bit lighter
I'll watch the mpg with interest, but now I'll never know if it's the exhaust or the tyre pressures

[steve_earwig]

Sounds about right. Hey, maybe it'll be both!

[Welly]

Eh up Doggy

You will definately see an increase in mpg

As someone else said - most garages/tyre places just blob 30 psi in and that's your lot

[swiss]

Idd, even if you've got loads more or less in your other three, buy a replacement tyre and they'll bung 28-30 in for you unless you ask.

I realise an estate has more weight to deal with across the back, but a saloon's pressures ought to be more or less even, right? Perhaps even a little more in the front when the car's empty, to accommodate the mass of the plant? ATM I'm puffing 'bout 35 psi in the whole lot.

And yes doggy, 1 bar = 14.5 psi, or there abouts.

Note to self: pump tyres tomorrow. Also, consider buying diesel so that annoying light on the dash'll go out ^^
