I'm new here, and only recently bought my Liberty GT 2004 a few weeks ago, it was basically stock when I got it. Since I've had it I have bought a new set of wheels, I went from stock 17s to 18x8.5 with 235/40/18 tyres. It could be a coincidence, but since I've had the new wheels I've noticed a rather noticeable decrease in acceleration, Is this possible? Could it just be that the wheels are bigger and heavier, or perhaps the wheels are rubbing on the inside of the guards (though from the look of it I have a decent amount of space in there) It just feels overall a little more sluggish.
Any thoughts?
