I am getting 30 mpg but I am riding on the 20" staggered,so on 17-19" s pretty sure upto 37 mpg is easily attainable. |
As a matter of interest why do you feel your 20" setup is causing you to loose so much economy? I know your tyres are wider than the standard 235s' fitted on the 17" rims, but that should not hammer your consumption that much? I would have thought rolling resistance is biggest factor affecting fuel economy, and that is a lot to do with the type of tyre fitted rather than its width. i.e. a partly off road ATR 235/65/17 tyre will probably have a higher rolling resistance (due to the knobbly tread pattern) than a hi performance semi slick 285/40/20.
