I am trying to decide if I should put 286/75/r16's on my stock 2003 GMC Sierra Z71 with a 5.3. Currently I am running on 265/75/r16's without a lift or turned keys. I think it looks great. I'd love to hear any thoughts about the pros and cons of going with a slightly bigger tire. I am excited about the bigger tire stance, but not excited about any possible extra wear and tear, diminished power or fuel economy. Thanks for your help!
