I have a 2006 6MT sedan with the 18" sport wheels I am looking to get some 20" wheels.
Below is a list of the available offsets for the front and rear wheels I want.



I am looking to get the maximum wheel lip while still being able to have the tires fit inside the wheel wells without rubbing.
WHICH IS THE BEST FIT FOR A 06 SEDAN?

Front:

20x8.5 +20 offset
20x8.5 +35 offset
20x8.5 +45 offset

Rear:

20x10 +25 offset
20x10 +36 offset

Lowering Questions:

1. I do plan to lower the car about 1" or whatever slightly tucks the tire how will this affect choosing the correct offset?

2. Lowering the car pulls the wheels in right? so if your 20x10 is rubbing in the rear will lowering the car 1" pull the wheels inside just enough to eliminate the rubbing issue?

Tires Questions:

Front 245/35/20 will it work with all these offsets for the front without rubbing? +20, +35, +45?

Rear 275/30/20 will this tire work with all those offsets without rubbing? +25, +36


Thanks

 

front: +45 will work, +35 might be pushing it
rear: those offsets are too low, you might be able to go +38 or +40, but with both of these you would have to roll your fenders. +45 rear and you don't have to roll them. search this, there's so much talk about offsets

when lowering, it does pull the top of the wheels in, not the entire wheel. you should get a camber kit to save wear and tear on your tires though, and if you do this, your back to what the wheel was before you lowered it, offset wise anyway. technically if you didn't fix the camber, you could tuck a lower offset, not sure the number though

 

In the rear I think the widest you can go is 9.5 without having too many rubbing issues. Safe offsets are 38+ for all around. Usually anything lower you may have some rubbing issues. You can get away +35's maybe but if you want something safe with no rubbing issues I would go with a +40.

Put it this way, anything under 35 you will have rubbing issues on a sedan. Also, stick to a 35 series tire if you are lowering. If not lowering go with a 40 series tire to fill in the wheel gap more. However, you said you were lowering so go with a 35 series tire

 

see my old threads...

20x8.5 38mm offset 245/35/20 tires

20x10" rear 42mm offset (need to roll rear fenders no rubbing w/ 5 people) 275/30/20 tires

i'm dropping on 350z h&R springs estimating 2.5" drop front, 2.2" rear

 

To the OP - SEARCH!

This has been answered 1000 times. 100 by me!

 

If you plan on an aggressive drop with fender modifications, you can do 20X8.5 in the front with an offset of +30 or even +25. As for the rears, 20X10 with +36 offset maybe doable but you'll have to run a minimum of 2.5 to 2.75 camber in order for the wheels to tuck. Fender modding must be done for this to work. - Mike

 

If you dont mind stretching the tires then you can fit the +36 in the rear. You'll need to run a 255/35/20 and atleast -1.5 degrees of camber. To accompany the look of a stretched tire in the rear, you'll need to run a 235/35/20 front for mild stretch with the +35. And you'll have to roll the rear fenders, no questions asked.
