33 inch tires would actually improve mpg's IF driven accordingly (my cherokee gained 3mpg when I went to 31" tires) unless they are SO much heavier than stock as to offset the gearing advantage with rotational mass.

what is 463 gear ration? what is stock gear ratio ?

I kind of wish my tracker had a 6 speed more than I wish for one in my metro.

At 45mph I am turning 2500 rpm !!! really want that down to 2000rpm. thinking about taller skinny tires just to try and lower the rpm some more. its got WAY more power than I need :-) I think I can wring 35mpg out of it but I am greedy and want to push for 40mpg :-)
