will 20inch rims fit 2010 Impala
20" rims equat to a smaller tire profile like 40 or 35 aspect ratio (side walls) check your stock wheel & tire overall higth. It might work out to be the same? Otherwise a lift suspension & wheel well arch mod is needed. I saw people using poly boat trailer rollers on the frame to lift the car, handling & ride will suffer. Discount Tire is good with this oversized info, ask them. 40 & 35 series tires sacrifice the comfortable ride & don't hit a pothole they will pop & damage the expensive rims. Better to stick to 1+ high performance oversized like 17's to 18's or 19's like a Corvette.
