If you want fat then 245/40 and 275/35. If you want "normal", then 245/35 and 275/30.

What are the specs of the rims?

Found this great reply by Neo on a different thread on fat setups:


"The term "fat" tire setup refers to using tire specs that would give you more sidewall than a "normal" setup. The benefit for low-profile tires would be more rubber which usually translates to a better ride.

I will give you an example for the GS, as that is my car.

In general, the only rim size that makes the most use out of this spec is 19. Typical normal tire size for 18s (I'll skip staggered setups for simplicity) is 245/40. For 19s, 245/35 and for 20s 245/35.

If we go by the definition above, the spec for 20s is already "fat" as to be closer to OEM size, you'd run 245/30. The problems with this size for 20s are that is is not as readily available and the rubber would be very thin (about 3") and will make driving not as optimal. Running this "fat" (but really for usable application, this is normal) size for 20s, we get the outside diameter (OD) of the wheel at 26.8" which is about 1" bigger than OEM.

For 18s, the side wall is about 4" for a 245/40 setup. This gives us an OD of 25.7, right at OEM. I suppose you can run a "fat" 18 setup at 245/45 with side wall of 4.3" and OD of 26.7". This would give you even better rim protection and ride but for many, the extra rubber for this setup takes away from the aggressive look of low-profile tires.

Now, for 19s which I said earlier is the size that benefits from the "fat" spec. 245/40 on 19s will have a sidewall of 3.9" and OD of 26.7". These numbers mean that the 19s will ride as well as 18s, will have minimal impact on visuals as the sidewall is the same as "normal" 18s, and will give the car the extra lift (since the OD is the size of 20s) for more ground clearance while reducing the fender gap better (also because of the OD), and thus requiring less of a drop.

There is a bit of rubbing and fitment issues when you are running at the OD of 20s. This is one of the reasons why some prefer to stay at the OEM OD.

Anyway, it is a personal choice of how each person want the balance of ride quality, looks, and compliance to OEM spec.

Believe it or not, this is only a slightly detailed overview since there are a few other things to consider but hopefully, this gives you a start on understanding this "fat" term better."

Thanks for digging that up. Either my connection or CL or a combination of both is kind of slow today so it would be frustrating finding the thread. You saved me a revisit later tonight.

the wheels are of course is a (19x8.5 42mm offset with 60mm lip and 19x9.5 42mm with 91mm lip) I don't want to slam the car so thats why i'm going with the cs setup plus the ride comfort,but i would like to sit the car on the tire as close as i can and some of the pics I have seen they dont have the wheel size or if it's lower than it would go.

Sounds like you are good to go. The CS will be perfect for what you are planning.
