The percent off on speedo math is pretty easy, it's just new tire size divided by old tire size times speed, or drop the leading one and that's the percent off you are. 32 new / 29 old = 1.10, or 10 percent.I full on agree with alll of the above. ^^^^.
My car is NA and pulls 5th fine by me… for now.
I have done some top speed pulls a few times and saw 72mph. Which isn’t crazy fast at all in comparison to a turbo cars capabilities. But it does lead me to a question I’ll throw out. On 32” tires how far off is the speedometer? Where and how is it finding that information? On my yota if I went up 3” from stock my speedo might me off 7mph at 72mph putting my true speed at 79mph. And IF that’s the case 72mph seems definitely fine for a my NA YXZ.
