Does this sound right?
I had 4 x new BF Goodrich AT tyres fitted not that long ago. 265 75 16 on boost alloys.
Over the last few tanks (fairly soon after i replaced the tyres) i have noticed a drop in mpg, down from average of 33mpg down to 26 -27 over the last few tanks, doing similar driving. Thats about a 20% drop! Before anyone says anything, the normal MPG for my driving and truck is about 33 average over about 10000 miles, so its a definate drop in MPG.
Also i have noticed it feels a little more sluggish and requires a little more throttle to get the same acceleration etc out of it, especially at low revs.
So my question is should these new tyres make a difference to the way the car accelerates etc and how much throttle is required etc to push it along. I have read that BFG AT are heavy tyres so would this make a difference?
I was possible expecting a little drop in fuel consumption moving from 235
General TRs to the 265 ATs, but not 20%!!
Has anyone else noticed this when changing tyres or should i investigate other things? Maybe i could check the MAF etc to see if its fooked and its a coinsedence?
Cheers
