Haha. I’m in Singapore. Right smack at the equator. So it’s only either hot and dry, or hot and wet. No winterised fuel either.

Actually, I currently only clock 20km/l on a route which I used to achieve 24km/l. That’s close to a 20% increase in fuel consumption. Which is making me wonder if it could be due to the tyre size alone or if something else is wrong.

I had on 215/40R17 Potenzas when I got the car. My new tyres are 215/45R17 Michelins. A few shops told me they didn’t carry 215/40 and had to make a separate order for them. Hence the 215/45s.

I have a Rapid Spaceback 1.0. I noticed an increase in fuel consumption by about 15-20%. Used to go 1000KMs with a tank of gas, but now it only brings me up to the 800KM. This increase in consumption seems to coincide with me changing all 4 tyres. I do not think its the new tyres' rolling resistance since the car seems to coast fine when i take my feet off the pedal. Neither do I think that my brakes are sticking. The increased fuel consumption can be observed when I put my foot on the pedal and accelerate as per normal, but the consumption figures are much poorer than before. Any of you guys have any idea what could be the issue?
