hi guys i have stock rims 18" , that came with the car i have a 2003 g35 coupe 6mt , and i need new tires my question is what is the maximum tire wideness i can go with out scratching i heard i can go 245/45/18 on the front and on the rear i can go 265/45/18 or 275/45/18 , if you guys have any ideas let me know thank you in advance

 

with 255 would be the safest... 265 is too wide IMO and not safe

 

This might help.

thank you for help

 

that means nothing... 265 or 275 is not safe...

 

i have 245/275 on my 19's, and its JUST FINE.

 

^^^ just fine... but not safe at all...

 

im not getting into this again. Youll be fine with a 275.

my 3700 miles with 3 autox's have something to say about 275's in the rear being safe.

PLUS the KDW2 is a skinny tire for its size.

AND dragging them ive had no problems. Ive cut a 1.98 on them... stock.

 

LOL, 3700 miles on 1 set of tires is hardly justification for claiming something to be safe, come back when you've done 100,000+ miles on multiple tires on that width without any failures like the tire manufactures do to determine safe operating ranges. Its one thing to decide for yourself to if you want to do something, and its a whole other thing to then extrapolate your limited experience to a general recommendation

 

ok, i will secede. Get a 265 and call it a day, but 275 WILL FIT and you shouldnt have problems, if you are looking to sit on fat tires, i would go 265 MAX on an 18 and 275 MAX on a 19.

 

iam going with 255/45/18 on the rear and 245/45/18 , maybe in the future ill lower it , im getting kind of cheap tires since i drive every day im getting the nexen n3000 i kno , u can laugh but im poor right know hehe : thanks peeps for the help

 

glad you went with 245/255

 

You want 245/40/18's on the front of your '03-6mt coupe.
255/45/18 on the rear.

 

yes...

thats the size i have right now on my 18''

 

+1 - That is indeed the correct sizes.
