Wow, only 20 lbs each for a 1999 OEM 16x7 stock rim??? That sounds almost too good to be true.
Can you please double-check the rim weight by holding it in your hands and standing on your home Bathroom Scale and then subtract your own body weight from the total??? It just seems 20 lbs might be a tad light, so please double-check at home with your Bathroom Scale to be sure. Thanx for your assistance.
