I have a 2290 sn# 9916355. Getting ready to paint it and the front rims are silver and the back rims are power red. All the literature and op manual show the back rims to be silver. Can someone enlighten me as to what color they should be? The tractor has not been repainted to the best of my knowledge. The 970 has a narrow front on it. The pedestal came off of an 830 (threaded caps). I used to run 6.50x16 tires on it. What are the biggest tires i can put on it? Would the 10.00x16 tires off a wide front work? If not can someone tell me what kind of a rim offset i would need? Thanks in advance!
