Will this fit? Tires are 235/40/18. Will I rub or will anything happen?
What if I get 10mm spacers? Would that clear the problems?

 

You would have 11mm less inner clearance and would extend 1mm out when compared to stock Si wheels. I wouldn't get those, way too tucked in. I don't like spacers as well. I have 18x7.5 +32 on my car, it's almost flush with the fender.

 

what he said. run no bigger than a 40 offset1

 

i got the 42 offset and fits perfect

 

i have 17x7.5 with a +45 offset and it doesnt rub. im also on sportlines

 

i have 18x8 +45 with a 225 tire and it rubs over bumps at high speeds.

 

isn't +45 our stock offset?

 

i'm running 18x8.5_+52 offset_245/35/18 clears suspension and rubbed off the top fender liner clips on both sides. other than that i track the car DD with no problems.

 

i dont mean to pull up a slightly old thread but.. my gf has a 06 Honda Civic 4DR and i was wondering what exactly is good to put on there for 18".
What is an "offset" i dont understand that yet.
My brothers gf has 18" .. dont know the tire size but im guessing maybe.. 35 x 8..
Its not too skinny of a tire and thats what i want.
Her car rubs likes crazy with weight on the back seat.
The wheels are about flush with the fender so im guessing thats why..

Any help? i want 18" with no rubbing at all. and i dont want a super tiny tire either.

thanks
