You have a smaller tyre, although you have better torque when moving off, but your distance covered per revolution of your wheel is shorter. 56mm/rev or 3.13% to be exact. But I think that does not translate into any significant loss.
I think the main reason is still your driving style. You may be more urgent lately and tends to step on the gas more.
Another reason maybe your engine is near to the end of service cycle. Especially for Spark Plug, old and foul plug tends to consume more petrol.
Hope you understand what I say.
Thanks and safe driving.

Btw, i'm a noob here so hope u dont mind my questions. Cheers. There are few types of spark plugs. Their recommended usage duration are as follows: a. Copper (standard, common type) - 15k km b. Platinium - 20k km c. Iridium - 30k km d. Silver - 30k km There are also some spark plugs (eg Autolite) that recommend 100k km. My take: change at 75% of recommended duration. The reason being the performance and fuel efficiency at the last quarter is usually very bad. I would rather change them (since they are not too expensive) and enjoy a much better driviability. Thanks and safe driving. Joey Lim
