Also - how will you know if the wheel change has any effect? If you look at your fuel usage, there's probably already a fair amount of variability from tank to tank.
I don't mean to be negative, just realistic.
didn't realise they would be a rare find in the US!
this was the other reason I was wanting to whack them on, the current tyres on the old rims are good year regattas which while not a performance tyre are more of an allrounder tyre, while they would have a higher rolling resistance, it will be interesting to see how the mirage performs with extra grip.
my mirage came with stock alloys, which im happy with the look of, just using the opportunity to try something different without an outlay of cost, will probably run the old rolla mags for 2 fills then chuck the stock wheels back on.
I do agree that plastic eco covers are the way to go if you want extra economy.
edit: well that was a short test! the wheel centre/hub centre on the mirage is slightly larger than that of the corolla! would only have been a few mm, cant measure exactly as I dont have any verniers available.
they would have looked alright though, would have been reminiscent of the volkswagen beetle with dragway mags look i reckon.
at least i got to test out the emergency jack and toolkit!
