Tires: changing wheel size, gas milege, chevrolet tahoe

I have a 2002 Chevrolet Tahoe 2/w/drive  with 265/70/16wheels. I want to put some wheels from a Tahoe Z71which or 17"  wheels  . What size tire do you recomend to keep as close to making my gas milege and speedometer the same. And do you think it will effect my brakes . Thanks Phil

Hello Phillip! In answering your question the closest size to your stock 265/70/16 would be size 275/65/17. This size should only affect your speedometer only slightly 2-4%, but also by doing this your going to limiting your selection in tires greatly and your cost per tire will raise also. Let me know if you have any other questions!
