Hey Guys, I've mentioned before on another post that I don't like how tall my 1st gear is in my truck. It seems like I have to slip it forever before getting going.

The truck came with 265/70R15 winter tires on it which even by looks appear much bigger than stock. I did the tire comparison chart with stock (225/70R15) and it says the circumference difference is 88.3 vs 93.0 inches = +4.6% difference.

In your opinions, do you think if I went back to stock with summer tires that the 4.6% difference would make a big difference on how my first gear feels or would this be negligible?
