Concorde tims question

Does anyone know what the biggest size rims can fit on a 2000 concorde?? i am getting ready to buy one and i want to start pricing everything up that i want to get for it....i would really like to put 22's but im not sure if i will have a suspension problem or if they would rub...i've seen cordes on 20's but mine has to be bigger and better than everyone else's....please help

Here is a CarDomain.com member who has a 2001 Concorde on 22's. It look like that's the biggest you can go. http://www.cardomain.com/memberpage/813437
