Any change in tire size will throw your speedo off. It will read about 10% low if you go with the 31" tires. You can correct it in the PCM. I did the same thing, and it doesn't drop the fuel economy much, maybe .5 mpg to 1 mpg. I don't know about those 3.55 gears turning 31" ties though. Somebody here might know better than me.

I went form 245 to 265. just remember the faster your going the more the needle is off, i painted my gauge cluster just after getting new tires. i left the speedo needle off and went out and did 60 down the highway (according to the GPS). i pushed the needle on at the speed the GPS read so that when i'm on the highway the needle will read vary close to my actual speed. Or you could just have it re calibrated. As for fuel economy it's just about the same as before, I'm running 4.10's
