Does anyone know all the possible tire size that can fit my 8? i dont know anything about tires. Please help

 

Are you really looking just for tires or do you mean wheels as well?
If you have the 18" x 8" wheels then 225-45-18 is stock and 245-40-18 is optional
Read through this section, search the tire sizes and check out www.tirerack.com

 

can 215/45 17 fit the 8? cause my friend is selling me some rims and tires for 300.

 

215/45 17 is a smaller overall diameter so your speedo would be wrong and you would accumulate more miles on the odometer than you actually drive the car. Not a good deal.

Also for wheels you need to get the correct offset and bolt pattern which I think is 35mm to 45mm
Hubcenter Bore should be = 67.1mm
Bolt Pattern is = 5x114.3

so its bad if i put the 215/45 17 on the 8? how?? (sorry if i ask to much questions i dont understand anything about tires)

 

215 is how wide in mm?, 45 is the percent of the width in height, 17 is the rim size you're putting it on

 

i think the width is in mm. im like a noob in the car subject. so is it ok to put on?

 

You just asked the same question three times! You've been given the answer already. Did you even read through tirerack's site? Take the time to learn about tire sizing, then you can answer the question yourself.

 

wtf?? i still dont get it.... hella confusing for me
