need Help understanding...
 

i have a set of 17' rims i just bought and there too big for my car.. cause the tires are 215/45/17 what i was wondering ... would i be able to put 205/40/17 on the same rim?
Please PM or email me if you could help
Thank you... =)

Yes you can.

thanks buddy you saved me alot of time and money...

usually you can go down or up one tire width on the same rim

Is it that the tires are too tall? It might be a matter of the wheels being the wrong offset.

If they're just too tall, you can also go to a 205/45/17 if you don't want the ride of a thinner sidewall.

i was wondering that also.. cause i would like to keep the width.. the offset on the rim is 38... my offset is +45 I believe. my cars a 2003 lancer oz rally.. in case someone might know more then me..

Stock height? Lowered (how much)?

Where/when is it rubbing? Straight over bumps? Turning over bumps? On the inside/ outside of tire?

when i turn and go over minor bumps... if straight away and no bumps it rides nice... so im assuming its the hight...

i was also wondering how you can put 40w and 45w on the same rim?... if it would make that much of a diff to actually rub

40 and 45 are the aspect ratios treadwidth/sidewall height in percentage .

so that doesn't affect fitting on the rim,check the tire manufactures website for what beadwidth(RIM) an individual tire can be mounted to.

ohh.. ok.. thanks..
how do i find out what the biggest tire size i can put on my car.. or anyone else's?...
is there a web site or something?..

thanks everyone.. for all the info... i know how it was the width not the hight that rubbed with my last rims... biggest tire i can put on is 215/35/18 if anyone was wondering...
