Check the overall diameter of the tire at the tread. It is possible that the tire/rim combination is now bigger than the stock tire/rim, which would effectively gear your car up, making it sluggish. You should probably consider using a lower profile tire which will give you the closest possible match to the original overall diameter.

The other answer is correct, but I'd like to add that depending on the make and model of your vehicle you can do ECM mods to change the shift points of your transmission. This would increase performance, but fuel economy will suffer (no way to escape that with big rims)

change your gear ratio

put the proper size wheels back on

A 6-71 blower and a six-pack on the engine............ You'll never experience drag again anywhere...........guaranteed. Except for, of course, Drag racing.......
