MPG with 265's
Hi everyone!
I am thinking about putting some Toyo Open Country AT's 265/75/R15 on my stock rims on a 1996 Chev Blazer 4x4. I was wondering how much this will hurt my fuel economy and I was also wondering how to re-calibrate my spedo after I do this. Thanks |

I lost a little under 2 mpg when going from 235/75/15 all-seasons to 265/70/15 all-terrains.
As for recalibrating...you either need to reprogram your PCM (Wait4Me tuning, PCM4less), or buy a programmer (Hypertech Power Programmer III). |

or go to the dealer and have them do it.

RE: MPG with 265's
I tried that....all of my local chevy dealers said they were not equipped to make that correction for me.

RE: MPG with 265's
Thanks for the help, now any ideas on how i could regain my lost mpg?

RE: MPG with 265's
You would have to regear (go up to 3.73s or higher), or again with the getting the computer reprogrammed, you could modify your shift points a little...but that would adjust power a little more than mpg's.
