It would be nice to run the 11" wide rims but stay aggressive for that "right" look in the fender without tire rubbing issues!

 

I have 19x11 running et67... no rubbing, no rolled fenders and 305's

 

Let's define aggressive to mean as flush with the fender as possible without extending beyond the top fender lip.

1st, the diameter 18 or 19 doesn't make a difference as long as you adjust the aspect ratio of your tire up or down to keep the same outer diameter.

2nd, It is the offset aka the ET stamped on your OEM wheels that determines where the face of the wheel sits in the wheelwell. The width of the wheel in of itself doesn't matter either

Example: a wheel that is 19x11 ET63 sits exactly in the same location with respect to the fender lip (ie aggressive) as a 19x10 ET50.

To drive that point home. Take a stock 18x10 ET 65 wheel and slip a 15mm spacer in it and it now sits exactly like the 19x11 ET63 except that the wheel is 1" narrower.
ie aggressive

For the record I run a rear 17x11.5 ET 60 from a gran am car. I have rolled fenders and almost 3 degrees negative camber. They are tucked up inside the fender lips
I hope this helps.

 

^one of the best answers i've heard on this forum yet. Finally

 

Yes but when shopping for rims, ultimately width comes into play with respect to offset. As you stated above, one can adjust offset to make a wider rim "sit" identical to a narrower rim inside a fender.

I currently am looking at a 19" x 11" rear wheel with a 52mm offset, which to me seems very aggressive. According to the wheel offset calculator mentioned in a previous post (1010tires.com), it will "stick out" approximately 1 inch more than stock. Will this fit is my dilemma???

 

I would echo the post of others on this subject and recommend you stick very close (if not identical) to GT3 sizes.

Here is my car with 11 x 18 ET65 and 295/30-18 tires

 

Seems pretty aggressive. Best way to make up your own mind is..

Take a look at any stock 996 GT3 and stick a tape measure on there and try to find .43" of extra space on the outside of the wheel. If you think that will work out for you then cool.

 

I'm having a similar tire/wheel issue on my 01 C4. there is a metal bar at the lower front end of the rear wheel well on my 2001 C4 NB. What is that metal bar? That seems to be the limmiting factor for me when trying to run a wider tire. I wanted to use 305/30/19 but that bar is where the tire rubbed. If I chose to go with spacers at that time then the fender rubbing would become the issue. And even so a 0.25inch spacer was not enough to prevent rubbing on that bar. It seems like lots of people have this issue but then i see people running 305s on this same car without a problem...what am I doing wrong? Anyone who can help would be greatly appreciated. I'll post pics so you can see what I have now.

 

pics of this bar?.... I ran 305/25/19, no issues at all. Sounds like you have offset issues...

 

 

I have 19x11 running et67... no rubbing, no rolled fenders and 295's. I did have to modify the inside portion of the plastic fender liners on the rears to clear the tire.

 

I guess it all depends on the tire brand you are using... I have Invos and they clear just fine...

 

you need to give us your offsets... running 19'/11, lowered... not much room to play....

305/25 is the correct profile.... I use Pirelli P-zero Rosso.... 305/25 are very hard to find.

 

Just our of curiosity. Has anyone tried stuffing some 20's in there? On a NB that is.

 

You're kidding, they look like 19's! Well, somehow they look bigger than the 18's that they are.

BTW, what wheels are they? I would really like to get a set too. I'm running 19's on my 996 C2, but if I can go back down to 18's and still have a look like yours, I'd do it.

Do you happen to remember the front offset and width, and tire size as well.

Thanks.
