It sickens me, how little you all know about tires.
Especially when it comes to sizes.

stock turbines... i just stuck w. what it had, 225/60/15. to make life simple.. like i said before,,, i dont really care about the tires performance... mt et streets are comming real soon...
i ended up getting kumho touring plus 732 theyll be good nuff for street use, when i hit the track, or go out intending to want good performance, the DRs that im soon getting will go on

well pro... since you asked.. i guess we can re-visit an old post of mine. It has become increasingly clear that the average car owner is "misinformed" about tire sizes and how the sizing works.
There are 3 parts to a tire size.
Tire width / Sidewall height / Rim size
Many people are under the impression that the "sidewall height" of a tire is the second number in a tire size. Although this is correct, its not really the truth. The second number in a tire size is a percentage of the width of the tire which makes its sidewall height.
Case in point, a stock 225/60/15 tire from a fox GT. It has a section width of 225mm, but the sidewall is not 60mm tall, it is in fact 60% of 225mm which is 135mm.
This is from a very old post of mine, it dates back to when i first joined the forum. RicePatrol posted the same exact assumption that many people make in the size of the sidewall of a tire. Read the below attached thread.
This is actually VERY incorrect. A 225/60/15 has an overall diameter of 25.6"
the "60" in your tire size is NOT 60mm. its a percentage of the tread width of the tire. in this case being 225mm
so although your math is correct, your variables are not.
225
100 = 2.25
2.25*60= 135mm
(135mm*2)*.0393701 = 10.629927
~10.6+15= 25.6"
(i used to sell tires)
*edit* changed formatting a lil bit
i figured is add this too
my rear tires are 275/40/17
275
100 = 2.75
2.75*40= 110mm
(110mm*2)*.0393701 = 8.661422
~8.6+17= 25.6"
so im even rockin the same size tires (overall)
Your new fomula should be
Section width divided by 100.
multiplied by the sidewall height number (your tires. 60. mine 40)
multiply this number by 2, then .0393701
add Rim height and you have your overall tire diameter
((((W/100)*H)*2)*.0393701)+R <--- for you math nerds!! (remember your order of operations)

hey topless, it asks for tire size, that would be including your sidewall.
Correcty me if I'm wrong guys;
Stock tires on my stock 15" wheels (87 GT) are 225/60/15
that means a 60mm sidewall.
multiply that by 2= 120 mm of sidewall.
according to my calc. that's an additional 4.72 inches.
Add 4.72 + my 15" rim and I get 19.72 total height.
To do is yourself, my calc. says the conversion factor is
1 mm= .0393701 inches
so your sidewall height, then times 2, then times .0393701.
add this to your rim size and your set.
Hope this sheds some insight.

That's all well and good There's a lot of helpful info there. Maybe that's what you should have posted to begin w/ instead of coming off the way you did.
There are a lot of knowledgeable ppl here, but there are more that are not. Hence the reason for their questions. Make sense?
