Help. Serious thread please, dont jack it.

[fawk_you]

I need this information for a court date that is coming up April 12th. They are trying to prove that the speed-o on my car was wrong due to the size of the rims or whatever compared to stock size. I cant get the information due to not having the car in my posession... I cant have it calibrated. Thanks ahead of time.

With a known radius, what is the forumula to compute the circumfrence of a circle.

Known radius, 15" and 19"
7.5 and 9.5


3.14xRxR right??? or what?

anyone heard about TED danson joining cirque de soliel ??

Yea I remember hearing something like that. lol Him and rosanne

[deffro]

Circumference= Pi * diameter

[ahmonrah]

yeah , here's a shot of them practicing in costume.

I need the links to prove it. :)

[deffro]

3.14* 15= 47.1
3.14* 19= 59.66

[HyPer50]

He's right... d x pi = c.. but why do you have 2 different radius'?

To prove the diff. between the stock tires and the tires I had on there.

15" radius? 19 radiu? so a 30" wheel and a 38" wheel?

you want to go by size of your tire vs stock tire. you can have a 15" wheel with a 195/65R15 on it and have a 16" wheel with a 215/40R16 and they are .01 inches off depending on manufacturer. This is how it is with my stoc wheels vs new wheels.

You can also throw a 215/55R16 instead of the 215/40 and its going to give completely different numbers and a large difference in circumference.

just food for thought since your brining equations into it you might want to further think it, hate to see the court tell you your looking at the wrong aspect of it.

[fawk_you]

^--thanks man. :)

[EP3sAreFun]

oh and i'd hate to be the bearer of bad news.... but the speedo is going to be less than acutal mileage if you have a larger wheel. tell me the mileage when you went from stock to the 19s and what the final mileage was and i can give you an estimate of how off they are.

[fawk_you]

what does that have to do with anything?

[thinkfast®]

just answer the damn question!!

quit stallin

[Darling Nikki]

thats weird....It hasn't done shit to my car even with 22's

[dereksi]

you prolly dont notice but im sure it changed it even if its a little bit.

yea it did.. you probly just too busy changin the radio and puttin on lip gloss to notice

RICKY FTW!!

pay the ticket and stop driving all together.

Well thats what I thought. But I even asked a bunch of people I work with and they even said nothing has changed. Now a guy with an srt-10 viper truck had 22's on it and he noticed a difference.

[thinkfast®]

PLEASE SEE MY PREVIOUS POST :D

[EP3sAreFun]

what does that have to do with anything?
your trying to prove that the OEm speedo is in sync with the circumference of your factory wheel, and in all reality you wanna go by the circumference of the tire, not the wheel. Technicly speaking if you put a taller tire on a car than whats originaly intended, your Speedo still reads 1 circumference=X amount.

When you have a larger tire on the same factory wheel it reads 1 cirumference=X, But the Cirumference is different, byut the car does not know to compensate, so whenever you chanjge from the orignal tire size in diameter your changing what your speedo reads, technicly speaking.

Please homie....I have better things to do while I am driving my g-ride um like watching out for potholes!

[thinkfast®]

HAHAHA I'm just messin wit ya damn!

your not going to see a difference, your speedo will read what it thinks is 1 mile.

_______________________
say this is your OEnm tire circumference drawn in a line



_______________________________________
and this is your new 22"s with tire




the car's Speedo reads by circumferences, which it reads as by how much the axle turns, 1 turn being X distance. So when yo change what the actual distance is, depending on how much the distance is changed, the speedo reads back differently.

[Darling Nikki]

^hmmm thats interesting....+1 for being so smart!

[IndianStig]

hmm, will the people who bought the car help you out?

pay them like $50 to come for a day

but yea

2piR=cirdumference

and your speedo will be wrong, it measures angular velocity (w), not linear velocity (v)

so it has a set group of measurements to calculate the linear velocity using the angulare velocity and the radius

so say W=5 radians/second

and your old wheels and tires had a Radius of 15cm

then V=W x R

5 r/s x 15cm

75cm/s is how fast your going

and the new tires are 20cm in radius

so it would be 5 x 20 or 100cm/s, but the speedo would still show 75, becase it uses W going into a calculator of constants

haha thank you!

[fawk_you]

I know you secretly have a crush on me. Its ok... you gotta deny it to everyone else...deep down, I know whats up. :taun:
:lmao:

Thanks to everyone for all of the real input...even to the thread jackers for bumpin it up. I sent everything in to the lawyer, says it will actually help. :goodjob: I gathered alot of info, and sent him what I thought was right... Even a little bit can make a difference. :)

Go ahead and close this up. THANKS AGAIN!

[B16a2 Civic]

hmmm, this is all interesting.

[thinkfast®]

yea B, I opened up this shit and was like "got damn" and I made a face like if something was gonna fall on me.. I kinda leaned back in my chair too

[speedminded]

it doesn't matter one bit about the wheel size...it's the tires!

[Tiff-O-Bitties]

I need the links to prove it. :)

go to google and try to search it.. i suck at shit like that so i can't help, sorry babe!
