Can't you just change the diameter of the tires?

for example, if one has a 4.4 final with a 195/55 15, what would the final drive then become with a 195/50 15? or a 195/45 15?

will this method actually work just like a final drive?

 

actually you can...

but you limit yourself what kind of tires you can get... not many company produce 195/45/15 sizes.

second you don't gain much shown below, but still gain.

If final drive is 4.40 and tires are 195/55/15

When you change to tires to these sizes it will be like changine final drive ratio
195/50/15 final drive ratio changes to 4.55
195/45/15 final drive ratio changes to 4.71

People autocrossing uses this as an advantage over other competitors.

a 225/45/13 tire has a really small diameter and stock civic tires are 185/65/14 has diameter of 23.46. As you can see, the car will be lowered 1.25. plus he gains in the final drive ratio changes to 4.92 if he has a 4.40.

 

how do you calculate the diameter of the wheels with tires? whats the formula

 

real constructive response, dickweed.


back to subject... one of the greatest street tires made is available in 195-45-15

toyo proxes T1-S

my friend has them on his EK hatch, and trust me... BIG difference over the 195-55-15 tires

 

I loved my Yokohama AVS 195/45/15's. Hehe...car accelerated great but you gotta live with a speedo that's off 5-7mph depending on speed.

 

Thank you Mike, my thoughts exactly!

 

Would the calculations differ between a 195/45/15 and a 215/45/15? ie, which part of these numbers constitute a final drive difference?

 

the seires (45,50,55)

ex. 205/45/16

205 = width (contact area)
45 = series (width sidewall)
16 = inside diameter

THe series and dianeter of the tire will both change the FD ratio

ok, but what about those of us with a 4.785 or 4.929 final?

What would these smaller tires effectively make the final then?

I intend to kick *** in autox next season! lol

 

so does changing the FD gearset to a higher ratio affect the speedo? will it be off?

 

formula?????

as well , does anyone know exactly how much it will alter your speedo? meaning if I change from a 195 55 15 to a 195 50 15 how off will my speedo be? what about a 195 45 15? is there a formula to calculate the difference in the speedo between the 2 tires thats correct? just curious because If I do infact go with a smaller diameter tire, I want to have some sort of idea on the correct speed im going, not just a guess

fuzznuts... you just made yourself look even more like a moron and an ***. Congrats!

 

HAHA...that's funny...geez to be young and naive...

 

Ron Jeremy works for Acura?

 

WOW and the owner of IPS racing is John Belushi <excuse the spelling> or is it james...well one of those guys...you were in animal house right?

Yes I'm alive Left the comedy business to sell performance parts hehe

John was in Animal house and Blues brother Etc, his brother is Jim, has a TV show movies.

 

haha...ok well in all seriousness...this is a rare good topic of discussion...so those of us w/ the JDM F/D or the AKT F/D...and we run the 195/45/15's that would be some outrageous number eh?...<---Eric who is happy that this isn't another newbie topic on "the best cams set up, the best header etc. and Toda vs Jun etc " oh yeah and what happened to that FAQ suggestion eh?...Eric

 

Hey, that was my line.

On the subject... DO NOT RUN anything less than 195/50/15's on the street. 195/50/15's barely do a good enough job of not bending/cracking your rims. I can't imagine what 195/45/15's would be like. (Yes, I did run 195/50/15 P-zero's for 4 years on GSR and EK hatch... one night I hit a pothole and my $300 15" rim was bent. )

 

Will that little tire trick kick you out of stock class in autox?

 

No, it won't kick you out of the class. But, if you shell out money to get new 195/45/15 T1S tire, you might as well pick up slicks.

 

No, it won't. However, I run tires with just the opposite philosophy. My fronts are 225/50/15s, which are even taller than the rear 205/50/15s. This is an unfortunate byproduct of trying to get the widest footprint I can in the front. However, I beleive that the added width in the front makes up for the taller size, and even though launching off the line sucks with these tires, the R in first gear will still spin them freely.

Ron Jeremy RULES!

Check out where I live man... I need a tire for wet and dry..

 

Hey, love him or hate him.. everyone has their own opinion of the man Ron Jeremy.

Fuzznuts, you don't provide much of an argument.
To answer your idiotic question, I don't know where a dickweed grows... where are you from again? Maybe that will give you a general idea..

But back to my response, can you please enlighten me on how your response was actually worth anything? The guy posted a good question, and you click the three times. Dude, you're awesome.
