i have an 03 with prem package
225/45R18 and 245/45R18
I guess I have 18x8 all the way around right guys?

now without changing the overall diameter(thats rim and tire both)..what is the recommended 19" rim and tire for me?

am i suppose to be getting 19x9 all the way around?I want to try to keep the same width i have now on the front and rears

all help is appreciated..thanks

 

Coupe, sedan?

my 03 has 18x8 on all 4, so if you have the coupe, then yes.

You dont have to stay the same width. Most people when upgrading, run staggered. 19x9 or 9.5 and 19x10 or 10.5. It really depends on what offsets you want to run. Do you want a big deep lip?

To keep the tire and wheel near the same dia. you need to choose your tires accordingly. Try this

what is the widest rim and tire i can go with that wont pass the fender and stay basically under the fender the way the stocks are now on my coupe

 

The recommended staggered 19" upgrade:

Front: 9 - 9.5" wide with 245/35 tires
Rear: 9.5 - 10.5" wide with 275/35 tires

 

Why dont you just buy the 19 inch sports rims from the 05 or 06.
