I own a 2wd 2013 4.6l platinum grey Tundra and I can't decide. I like the look of the 275/65 on the 3/1 but I don't want to deal with the speedo and mpg loss. I do a lot of driving and I don't want to regret this decision. I recently purchased the platinum 20's and I plan on getting the Nitto Terras just cant decide on a size. If I go 3/1 I will definitely be getting the coach builder +2 shackles. Pics would help but any advice is much appreciated.
