rim specs...need help..

what does this mean... 205/40/17...can you give me specific info about those numbers..
tnx...

I'm no tire expert, but I'll take a stab at it. The 205 is the width of the tire, the 40 is the thickness of the tire and the 17 is the size of the tire or of the rim that is going to be mounted on. Hopefully that gave you a little insight of what you wanted to know. Peace :alien:

hey..thanks..helped me a lot..anyways what do you prefer a tire width to be?

No problem, as far as the tire width goes I would go from 205-215. You don't won't to go to wide.

205/40/17

205= size of the tire ( circumfrence )
40 = size off the rim ( how low profile is -tire thickness- )
17 = size of rim the tire is wrapped around..


something like that.

i thought it's nice to go wider cuz you'll have a bigger floor patch which means more grip for the car....maybe it's only good for autoX, i dunno, but 215 is perfect cuz our car isn't as heavy as a mustang or a camaro which they use a 245 width....only drawback of having a wider tire is it adds more weight to the car

205/40/17

205 is tire width in in millemeters.
the profile is 40, which is 40% of the width
17 is the rim diameter.

Hope that helps.

i thought 40 is in milimeters, not a percentage?

Use this link it has everything you would ever need to know about tires.

Yeah i just wanted to say that another drawback from having wider tires, is a bigger contact patch which may or may not be good cause if you're racing drag or going for top speed then you need really skinny tires on the wheels that aren't powered, that's why top fuel racers have those really small "bicycle" wheels on the front and gigantalorious tires on the back. But if you need any sort of good handling then wider is better

so ill go from 205 to 215...it sounds good and probably it'll look good and im really not into racing yet cause i want to set up my car before racing...thanks for the inputs!
