Do you think that I can get a 31x10.5 on a 16x8 wheel??

 

mine are stock 16 x 8, the 3 rim sizes were 15 x 6.5, 16 x 8 and 17 x 9, as far as i know, if you have a sport or sxt you have a 16 x 8, if its earlier than 2000 its a 15 x 6.5 on sport and regular models, the only trucks with 17 x 9 were rt's and special order
