Does anybody know if 245/35R20 will fit on my 2005 Grand prix gt? 
Thanks in advance

    You'll have to fit one or two and see---as far as speedometer error goes, (circumference) and height (for wheel clearance up and down with suspension working) you should be fine but your "new" tire is about 8% wider, (7/10ths of an inch wider) so you'll have to check for clearance problems while steering.
