Yeah, i'm working on it - annoyingly my best eco route has just been resurfaced so i'm avoiding it for a few weeks till all the loose chippings have been scattered (so they arent chipping my paintwork).
Seems switching to the 15" wheels is sadly neither easy or cheap - maybe i can find someone on the Prius forum who wants a free upgrade to the 17" ones...
Our Honda has snow tyres. The Hyundai had the best eco tyres available, as will the Prius. Its rarely cold enough here to justify winter tyres on the daily driver.
Its the chump accelerating towards me who could do with better rubber!
Last snow tyres i bought for my car went on a Rover 75 less than a week before i scrapped it, gutted!
Ben here's an interesting fact about the Prius, if you travel to inner London any time soon, you'll have to pay the congestion charge, however if you have the 15" rims, it's free. You see the new rules are that only cars that emit 75 grams of C02 per km and below are free, the Prius on 17" emits 76 grams, just one over, whilst on 15" it's just under. Why not do what I do and get some aftermarket rims in the size you want, and dry store the original wheels to keep them in tip top condition? You'll probably be able to get A or B rated fuel efficiency tyres easier for the smaller rims too.
I want the Prius ones - i'll see if any Prius owner unhappy with 15" wants a free upgrade to 17". I had heard about the congestion charge discrepancy. Unlikely i'll be in and out of the zone though.
I want them for the potential 10% improvement in economy.
