I'm going to add that your larger tires DO have more "mass", which means there IS more power needed just to get them rotating (along with the increase in weight they add to your truck, the increased "rolling resistance" due to the larger footprint and the increase in wind resistance you'll see at highway speed due to the larger frontal area).

Yes! I did say 17's. Sorry, after I talked to him I was corrected. It is the same truck. Jack, in your opinion, why would the canned tune 0-60 be quicker than my Custom Tune, even if we are dealing with a tire size and gears issue. Seems to me, that I should have picked up some and not lost power from the Custom Tune. My neighbor also corrected me on his 0-60 time. He said in 87 Custom Tow he is at a 7.37s 0-60. Thanks, for all the input!
