I have some 44" boggers with rims in the tires section for trade or sale.....I am not sure what to ask for them..I would like to get enough to buy different rims and tires for my new application. I guess my biggest concern is shaving the calipers on the D60 for 15" rims...this is my daily driver the thought just scares the cr@p out of me, especially since my kids ride in it every now and than. need advice !!!!!!!
