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 |

Re:Bigger wheels/tires = higher top end correct?
bigger tires give you more top end

yes, bigger tire=higher speed at same rpm and speedo reading slower than actual speed. |
Re:Bigger wheels/tires = higher top end correct?
yeah
this guy was aruging some fucked up points just a second and i'll psot the conversation |
Re:Bigger wheels/tires = higher top end correct?
oh no, a conversation, I'm way too lazy to read that crap.

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.

Re:Bigger wheels/tires = higher top end correct?
I'm not gonna bother reading your conversation but I will insert my 2 cents,
Think of it this way, you have a tennis ball and a basketball. You roll each of them exactly one full rotation, which one would have covered more distance. There's your answer. |
Re:Bigger wheels/tires = higher top end correct?
man that`s one piece of ---- that u talked to.
he THINKS he knows everything. explain to him with final drive ratio assuming youe car only has 1 gear. ask him y does taller gear gives u more mph at the same rpm then ask him y does shorter gear gives u less mph at the same rpm if he still don`t get it, bat a hundred bucks with him and have him ask his instructors/ or whoever |
Re:Bigger wheels/tires = higher top end correct?
well that is the same thng as
7000RPM in 5th gear RPM = rotations per minute it is the same number of rotations per minute, but you have a bigger wheel. speed = distance moved/time well since your time is the same, and rotation is the same, then the ditstance around each tire is not. the bigger wheel, more distance, more distance, more speed |
Re:Bigger wheels/tires = higher top end correct?
ok.. lets get something straight.
the top speed (gearing) will get higher if the OVERALL WHEEL/TIRE circumference is more. (distance around the tire) so if you go from 15's to 17's you wont see any difference because you will get a thinner tire to match hense retaining the original rolling diameter. you 'could' get 180/60r17 but that would look homo on any car other then a lifted truck. in your "conversation" you stated that you would get a higher top speed from going from 15's to 17's.. that is incorrect. as most people get a 205/40R17 tire. understand? |
Re:Bigger wheels/tires = higher top end correct?
well in his first 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 |
Re:Bigger wheels/tires = higher top end correct?
the sidewalls are the same based on those specs
185/60 so the extra 2" in diameter would make a difference since the tire sidewall is the same |
Re:Bigger wheels/tires = higher top end correct?
Ask that crack head how those old bikes with the huge ass front wheel were able to go 40 mph with out really tryin...Hmmm... Go put a 14 on that bike and go 40 mph

yeah it was just an example...
even with 205/40s on there...it is still going to be diffeerent |
Re:Bigger wheels/tires = higher top end correct?
you'll have a tad bit more top end...but you'll be a lot slower thoihg :-\
Someone with some light 15's with ab it less power then you will give you a beating. I've seen 15's weighing in at 13 lbs some even less depends on material and make. |
Re:Bigger wheels/tires = higher top end correct?
My DIV.3 16"s weigh 12.6 lbs.
the 17"s he was looking at in stevemode's thread are 18lbs fake spoons are like 13lbs at 15" 15 or so at 16" TE37's are less then that. my wheels are pretty expensive TE37's are more then that fake spoons don't weigh TOO much less those 17"s are like $350 if you can clear them in your wheelwell, buy them. then sell them after you've drove on them a while and have saved enough money to buy a good set of wheels. |
Re:Bigger wheels/tires = higher top end correct?
i need to get some of those 17s quick....
at only 18lbs that isn't ---- i bet my stock si's are close to that too lol bling bling |

Re:Bigger wheels/tires = higher top end correct?
I had some dildo trying to tell me that he installed a "NOS" kit on his friends Eclipse, but the guy was too scared to use it, so he got in it and hit 90MPH in first gear. He explained to me that he made so much power that he gained top speed on his gears. 90MPH in first gear would have put his Eclipse at like 56,950rpm. ::)
