Does it affect mpg?

[Adz]

if i fill my tank and get 300 miles fomr it

then pot 33 inch tyres on and still get 300 miles

is it possible the milometer is now out of calibration due to the wheel size change, if the speedo reads diffreent then so will the milage? :augie

Not when I use GPS :augie

I worked it out on mine with 33s on the speedo UNDER reads by about 6-7% vs the sat nav.
I know with all my mods I'm still around 26 to the gallon
Which I'm quite happy with as I've got lead soled boots and roof lights and 'king heavy winch and it runs on bio at 82p a litre

that's abut all i get running standard! so you must be doing somehting right :thumb2

I think the key phrase in all of this is about, GPS (with a mileometer? :augie) or not. There is no way to tell unless the difference is pretty large.

The bloody speedo don't read right even with the correct wheel size & inflation :doh
GPS is the only way :thumbs

My Mav's got standard wheels and tyres, got roof bars across the top, filled up today it worked out to 32 mpg. Mind you I've driven like my grandma on the last tank.
