Just FYI I went from a 30.1 to a 29" tire on my truck and gained more top end which you are wanting for roll races or interstate races.

Went from a 255/70/16 to a 255/65/16 tire. Our setups are way different I know, but just wanted to add some info for others to read possibly.

Example before on my truck with the 255/70/16 tire I could floor it at 70-75mph on the interstate and it would kick you back in the seat every time, but if you tried to floor it above 75mph it had not so much *** and would not kick you back in the seat.

Now with the new 255/65/16 I notice much better top end, I can floor it at 80-85mph and it will kick you back in your seat unlike the old tires which would not at those speeds.

so just 1" can make a difference. "That's what she said too btw"

I have the shitty 3.42 gears too as well.

i run a 28" on street and slicks w/ 3.42's. shouldn't need any taller as long as it will hook. some big power guys prefer a 30" slick.

Yeah try to find a happy medium, you don't want to get too small of a tire either.
