Ok how do i figure out what numbers mean when looking at tires? what do the xxx/xx/xx stand for all i wanna know is how do i determine a real thick tire to a real thin tire? i want 17x7 and i see this deal and it says the tires that come with it are 205/40 R17 what does that mean also?

xxx/xx/xx stand for this -- tread width/aspect ratio r rim diameter

(first the technical, then the simple)

Using 205/40 r17

205=tread width in millimeters (how wide the tire is, this would be about 8")
40=Aspect ratio (how high the sidewall is as a percentage of the width... in this case it would be 40% of 205 = 82mm or about 3.25") -- aka 40 series tire
r17 = Rim diameter... or a 17" rim

A 205/40r17 will have a smaller sidewall than a 235/40r17 because, even though the percentage is the same, the tire is wider...

You actually want to go with a either a 225 or 215/40 r17 to maintain the overall diameter of the stock tire. (keeps the speedo accurate)

Someone on the board gave me this link a while back, it has a lot of information on wheels and tires.

205/40/17, 215/40/17 or a 225/40/17 are all too small for our cars. you want a 215/45/17 or a 22545/17

yeah I was gonna say that also, 215/45/17 or 225/45/17.

R17
R is Radial from the days when there was Radial and Bias. You had a choice. Before R it was steel belted.

So are you saying that you have finally mastered the fine art of the button or are you being a braggart about how you mentioned to Mr. Bautz that he search for his answer? You are not being too clear as to your intention.

just @!#$ die already your worhtless. atleast his question was a some what good question where as you ask. "how do i put neons in my car" and "how do i install a shift knob". i hope you get hit by a bus so you cant reproduce

haha what you are allowed to send someone to search and be an @!#$ ive seen you many time here being a @!#$ @!#$ when somenone ask st that for you easy so easy that a monkey can do it
and when i do the same thing you get all bitchy haha at least i respect kardain he didnt attack me because of what i said he behaved in a good manner and kardain yes i have improved my search abilities

no the thing is you ask stupid questions that a simple search or a look in the faqs would explain. this however is a slightly (well for you way more) advance question then what you ask. the only reason i posted in here was because the wrong infomation was given out and i wanted to make sure it was corrected before he purchased the wrong size tires. you ask the most stupidest @!#$. hey where did you get this or where did you get that. how do i take off a shift knob? when they answer is right in the faqs which you choose to ignore. you need step by step instructions with detailed pics of the most easiest of things. i understand your new to cars but your lazyness isnt going to get you far. i say search because im sick and tired of people asking the same question and looking to be spoon fed info because they cant use the search button properly.

205/40/17's will fit but your speedo will be off and the tires will be like rubberbands, making it a rough ride.
