Larger dia tyres will use more fuel... but... don't forget you will now travel further than your Odo thinks you have.Originally Posted by Sprock
I was thinking the fuel usage jumped when I put the chip on it but I just realised I put it on the same day the 33s went on so that might be the reason for the fuel increase ? I think standard tyres are 31" ? I remember they were road tyres & looked like they were off a commodore

If you haven't already done so you will need to check your Odo calibration and use a fiddle factor in your distance travelled.
Note that your Odo error may possibly be significantly different to your Speedo error.
