18s all around
 

Due to stock tire availability I am thinking of going to 18 inch rims on the front. planning on using 275-35/18 on stock rear rims for front and staying with 295-35/18 for rears. Looking at Conti Extreme DWs.
Will this set up cause any traction / active handling problems and how will it look vs stock sizes? appreciate any pics with this combo.

I used to run the exact same size tires - no issue at all. Below is a pic:

Just 2 weeks ago I put 18s all around on my 02z...with the original F1 295s all around as well. I get some weird bump skipping if youre at full lock going slow, but nothing in normal driving. Made the size upgrade to make it easier to get tires in the spring (and rotate them). Going with Michelin Pilot Super Sports all around 285/35/18s. Theres another member running the same setup with no issues. I dont think youll have any problems with your setup. Id suggest even running a square setup like I plan to do to let you rotate your tires. Happy motoring!

Won't the square set up cause problems with AH/TC. Thought that the rear tire needed to be taller than the front tire.

In theory, yes. In practice, no. I did a ton of research on it and couldnt find one case of the TC not liking the square setup, even in track settings.

I'm running the exact same set up as the op is asking about.....no issues at all with mine. I also run another set of 18" Speedlines at the track with a 315/30 squared setup with zero issues.
Here is a shot with 295/35/18 rear and 275/35/18 front

I planned to chime in here, but these guys got it covered :thumbs:

Thanks for all the inputs. Looks like 18s all around are the way to go.

conti dw my next tire, next year, i have 18x9.5 and 18x11 with 265 and 295/18 currently, but no longer available in brand i have

:iagree::flag:

The Michelin PSS also fit fine all the way down to 265 wide on the stock rears. 4x rears with 265 PSS's:

I'm running 265/35/18 on the front with no issues. The 275's won't cause any problems either.

Just curious, why 265 and not 275? Does the 265 front look better with the 295 rear or is it due to brand availability?

265/35/18 is the closest size to the stock tire dimensions. I'm running Extreme contact DW's and they are available in both sizes. There is also not much difference if you step up to a 275 width tire.

Looks wise. I don't think there will be a drastic difference but some of it will depend on rim width also.

I'm running 18's all the way around...great choice IMO.

I'm planning on running 10 1/2 wide rims all around (stock speedline Z06 rears).

Ok, then you probably want the 275 size in that case.

265/35R18 will mount just fine on the factory 10.5-inch wheels

There are cars that run 265/35R19 rears on 10+" wheels from the factory

Kinda off topic, isnt speedline who made them for 01? From my reading the 01 wheels were lighter right?
