hello ,
i just wanna ask what is the best offset for those rims so i can buy a right one this time. i dont want my tires hit the fender or stick out . i know it look sick but ..could you guy help me? thanks

what offset for these rims size and what tires size should i go with:
18x8 ??
18x7.5 ???

 

i dont think any of those will touch your fender .. Except if they were - 50 LOL .. just get the right size tires .. and you will be fine

 

18x8 +38 225/40-18

 

ohh okay thanks. one more Q. the less offset is the more stick out of the tires ??

 

that is correct sir..well the rim will stick out more

 

if you want to be a lil' flush 18x8 +30 or +32 with 215/(35or40)/18

 

Offset is not the only think you have to worry about. I have 19x8.5 +35 Exe Tenfolds on the front of my 07 TL-S and my buddy has 19x8.5 Works VS-XX +33 on his and do not clear the BBK by a good 10mm. The way wheels are made, makes a difference....but offset is key also.
