I am looking at getting new rims for my 06 RT w/R&T and I have comtemplated getting custom chrome 18's and using the stock rubber. Then I would take the stock rims and put winter tires on. I have also looked at getting 20's but the price on rubber is getting more than I wanna pay. Any thoughts, opinions? Is it dumb to get custom 18's??? I am getting a great deal on snows though. Help!!
