    I've had my 19" wheels on for about a month now, and I'm sure it is effecting my MPG? I'm sure I'm getting less miles to a tank of juice. Would I be right to think that?

    Tyre is wider = more rolling resistance
    Tyre is taller = more wheel material = more weight
    Tyre is taller = effectively gives a longer gear

    The last point is a plus but it's probably negated by the first two points so overall effective on the fuel consumption is negative so yes, it probably will drop.

    You know, I think you should LPG your car :Tongue:

    ...last full properly calculated tank of fuel revealed 36.5mpg for my 2.4 ex Tourer ! & the tank before the same and the one before that nearly 38mpg !

    Why have milk (Diesel) when you can have cream (lovely smooth 2.4 VTEC petrol power )...Yummy!

    I'm having a run out to Scarborough at the weekend, so gonna take it steady and see what she does.

    Best I've had on a run at 50mph due to average speed cameras and being summer over a distance of 110 miles was 42mpg! Don't think I'll ever see that again.

    Other best was 34/ 35mpg to work and back.

    This is a pic of my MPG app on my phone after a trip to Scarborough and back over the weekend, me the wife, 2kids and a boot full of stuff!
    I was keeping up with traffic all the way I was trying my best to read the road and do less braking etc....

    Nearly 41 to the gallon, this was over 180 miles.

    I was speaking wiht my cousin who has just taken delivery of a 2 year old Civic I-DTEC diesel. He was a little disspaointed with the MPG. He gets around 50mpg where as his previous 1.8 petrol Civic was doing around 42mpg. He has a little more torque with the diesel but its over quick. Given the extra cost of diesel he hasnt really seen much benefit. I know neither of these are Accords but thought I'd mention it.
    +1 for the petrol chaps.

    Well, done a 410 mile round trip since yesterday and MPG came down when fluctuating between 70 - 90 I managed 34mpg at probably an average of 80 with a full boot, 2 kids and 3 adults. I tell you what, it drove spot on at about 80.

    I went from 16 to 18 inch since last week and it definitely is affecting MPG !! I emptied a tank this week and need approx. 0,5 liter more for 100 km (from 6,9 to 7,4 for this one tank).

    For real silk you need to have a 2.4 with LPG ! I did a run from Birmingham to London, 250 miles for £18.

    That's the cost equivalent of doing 73MPG in a Diesel :BooYeah::party::mosh:

    I'd love to get my 2.0 petrol on LPG. I'm heavy footed and I average high 20s low 30s most of the time. Better than my diesel Land Rover though..... High teens most of the time. Haha
