So my tires are starting to get low and Im thinking of upgrading. I think the best move for my build would be to go with 35s. I run 285/70/ R17 duratracs now. I love them and think they are amazing. I eventually want to run 37s. However, being reasonable, I cant afford them now. So I was thinking of moving to 35s and then keeping them as an extra set when I get 37s. Im wondering how badly my mpg will suffer moving to say 315/70/R17 duratracs. I currently average about 13-14 on the highway and around 11 city. I can get a tuner if it would help the mpgs a bit and I will need one in the future anyways. I dont have money for axle and gearing upgrades yet. I have 4.10s
