Junky tires, and a nice car.
@Ian Stephenson, yep these kinds of tires are rubbish, they allow for a (slightly) higher MPG rating while compromising handling, braking, (maybe) acceleration, and safety. @armyknife, one aspect of being a good driver is keeping your vehicle in safe condition. These tires I'm sure are technically legal, but they really are not remotely safe tires. I've been in several vehicles with these types of tires, and they don't corner worth a damn, don't stop worth a damn, and don't give any warning they are getting ready to let loose. So, if someone stops short in front of you and there's a drop of rain on the road, you WILL ram into them. My friend got rid of his after he got stuck because *1* out of 4 tires was in about 2 inches of snow (with the other 3 tires on dry pavement.) That was too much for it!
That said, I wish they'd sell some cars like that here in the states. They are starting to pay *some* attention, finally within the last year or two more 40MPG (that is 48MPG in your British gallons..) cars have come out than just the Prius and a few inflated-MPG Honda Hybrids, whereas before... well... you could either get some car with a nice torquey V6, where they'd pull out the stops for MPG and get 30MPG (that's 36 UK MPG), or a little 4-cylinder that they instead tuned and geared strictly for power, so it'd still be far slower than the V6 but also get about 30MPG. (This is why us US'ians had this apparent obsession with V6s and V8s btw... the car companies were supplying 4 cylinders with no mileage advantage over the 6, so why buy it?) But over 75 (US) MPG? Yeah, I'd be interested in that.
