Bigger wheels/tires = higher top end correct?
Okay so im into a little debate about stupid ---- well anyways
im saying: basicly: the bigger the wheel/tire combo, the HIGHER top speed you would beable to get too.... example: 185/60/14s zc tranny si fd 7000rpm in 5th gear = 126.91mph 185/60/17s zc tranny si fd 7000rpm in 5th gear = 143.65mph http://crx.honda-perf.org/math/ ------------------------- if you swap bigger wheels or bigger tires onto a car , your speedo will read slower than what your actual speed is going correct?...e.g. my buddy has 35s on his little truck and when you're going 55mph, if a cop gunned you, it would be like 67-68ish. ------------------------------------------ correct? same RPM, same tranny, bigger tire = you are moving more ground, speed = distance / time . more distance = same time/(rpMs)... ----------------- im not talking about acceleration, or anything like that. im speaking of the TOP speed that you'd beable to get to compaired at the same RPMs... let me know if im right |
Re:Bigger wheels/tires = higher top end correct?
In theory taller tires will give you a higher top end, that is, if the car has enough power to overcome wind and "----" (I had to do that because I want to fit in and be cool).
Yes the speedo will read slower than your actual speed in most cases if the drive gear runs off the diff. |
Re:Bigger wheels/tires = higher top end correct?
power isn't an issue. 300whp we will say...
wind doesn't count in this problem 7000rpm in both situations |

yes, bigger tire=higher speed at same rpm and speedo reading slower than actual speed. |

Re:Bigger wheels/tires = higher top end correct?
I almost made it to the end before I gave up concluding that you were talking to a moron. it's the same for auto and manual trannies, they both work on gear ratios, the only difference is how the power is transferred from engine to tranny and how the gear is selected, there are still gears in there with specific ratios. you gave him perfectly good explanations, he's just a moron. I would have you paypal me the .32 cents but then I'd end up paying paypal because of the fees, so ---- that.
