I agree with Tourashine, in that I doubt its the wheels. I am in North Manchester. Burnley isnt too far. I have a set of Devonports in the garage you can try to see if it make a difference before swapping out your wheels.
However I do think the mpg is a bit low. I have a 180 and at 65-70 on the motorway Im about 40mpg.
Over a take of fuel Im getting 35-37 ish mixed driving mainly a commute to work on the M60.
