I need to know why I'm suddenly getting significantly more mileage out of a full tank of fuel in my car. I have a new set of tyres and given that the previous set were literally bald, would the extra centimetre/s (or thereabouts) on the circumference of the new set affect the spin cycle of the input shaft to the odometer OR would the improved traction increase the fuel efficiency?

or perhaps these ones are inflated to the correct pressure ?

Always keep them well inflated, just didn't want to fork out for a new set until I absolutely had to

Quichy - extra rubber on your tyres (meaning a larger circumference) would result in the odometer running slower for the same distance travelled, not faster.
I reckon your improvement in mileage is a result of the new tyres having less friction and possibly also being better aligned and balanced.
I'm wondering if this should go in the Cricket Forum, but will post here anyway...
I'm taking Mini-Jase to the 20/20 game on the 20th of January, his first ever cricket match, my first one in years... obviously sitting on the hill near the scoreboard would be fraught with danger but if we were closer to the members stand would that be "safe" enough...?

Okay, I thought there may have been an inverse relationship there, but obviously not!

You would actually be travelling slightly further but odometer would still read the same. I think...

?? how could you travel further, the distance from point A to point B doesn't change.
1 revolution of the tyre will still give the same odometer/speedo reading no matter the tyre diameter, the actual distance travelled and speed travelled at will change if the tyre diameter changes.

if you increase the wheel diameter you'll actually be covering more kilometres than your odometer is counting?
Look at it this way; Current circumference for example 1m, increase the diameter therefore circumference might go up to 1.1m. Odo still counts 1 revolution as 1 metre, but you are actually travelling 1.1m.
