Bought a set of wheels that's 19x9.5 and 19x10.5.

Thinking about putting on some PSS or S-04 in 255/35/19 and 275/35/19, will they look stretched on 9.5 and 10.5 wheels?

A little stretched but not ghetto. Stock ZCP is 245/265 on 9" and 10" respectively so you are adding 12.7mm wheel width and 10mm tire width. Also, it depends on the wheel offset. 255 will rub the fender in front if the offset is too aggressive.

The offset on my new wheels are +23mm for the front and +25mm for the rear, not sure if that's considered to be too aggressive or not.

You will be fine with the PSS. The Bridgstone has a more square edge to the tire and may rub. The bridgestone is also seriously heavy.

And seriously cheap, I think the S-04 is over 30% cheaper than PSS....they're just too damn heavy!

BTW, what do you think about 265/35 and 285/35, serious rubbing?

FWIW, the spec sheet for most tires will list the acceptable wheel width. Playing with the offset on an aftermarket wheel is 'supposed' to be to get the thing centered per the factory options, so the clearances are proper, the track is within acceptable range, and the load on the bearings isn't compromised.

Selecting a tire and wheel combination that changes the overall OD from the stock also means you've changed the gearing which will affect the speedometer and odometer, and if front/rear OD's aren't close, affects the ABS as well.

I would (and have) run 275/30/19 and 295/30/19 on wheels with that size / offset.

A couple of pics with 9.5" et23 fronts with 5mm spacers (effective 17mm offset) and 275/30/19. Rears with 10.5 et25 wheels and 295/30/19 AD08's

Ah! I remember seeing pictures of your car with the G25 wheels before!

What suspension setup were you using when you had the G25? Also, any rubbing in the front or back?

BTW, did the OEM TPMS sensor fit on the G25s?

These would be perfect tires for 18" wheels. Not sure if you are running 18" or 19" since you only initially spoke about the width.

For 19", you could also run 295/30/19 (r) and 265/30/19, 275/30/19, or 255/35/19 front. 285/30/19 is a great rear size also to run with 265/30/19 front, but 285/30/19 is not available in PSS.

KW clubsport. Around -2 degrees camber in the front. I had to add the 5mm spacer to clear the KW spring on the inside. Very slight grazing of the front fender liner at full lock. No other rubbing but it's close everywhere. Camber and alignment settings will impact success. The AD08 tires are some of the squarest and widest available. I loved how the car drove with the above set-up. Grip was fantastic. I always run 275's in the front because I like the extra grip and reduced under-steer.

Unfortunately, I'm running 19", lol.

Do you think 285/35/19 rear is too tall? I was thinking about 255/35/19 front and 285/35/19 rear.

Could also do 275/30/19 front and 295/30/19 rear, but not sure if the 295/30/19 rear gonna rub with the +25mm offset. I am on stock ZCP suspension tho.

Yes.

Great information, thanks!

I'm on OEM ZCP suspension and stock camber and alignment settings, do you think I would need the 5mm spacer for the front wheels if I were to run PSS 275/30/19 in the front?

I'm such a noob when it comes to camber/alignment/wheels, a lot of stuffs I need to learn

You won't need a spacer in the front with OEM suspension (KW coilovers reduce inner clearance due to the helper spring). You will however want to add negative camber front and rear when running 275/295 tires. There are camber pins that can be removed in the front which allow about -1.8 degrees of camber. I wouldn't hesitate to make that camber change. That is very mild camber and will improve handling without any significant impact on tire wear. Without the camber change the tires may rub slightly and will look a little odd because the edge of the tire will almost protrude past the fender. This depends on the tire brand but I can say that Yokohama AD08's will require the camber adjustment (I needed it with Eibach springs which are slightly lower than ZCP).

If all of the above sounds like too much work, then just run 255/35/19 and 275/35/19 tires which will be slightly stretched but will be an easier fit. I have always felt like the wider tires were worth the effort but the 255/275 combo is also a good option.

The wheels are 1" or 25mm stagger. Whenever possible I think its best to match the same stagger with the tires and wheels. In other words I would run a 20mm tire stagger in this situation. The only two sizes I would consider are 275/295 or 255/275 with 9.5/10.5 wheels.

I have ran 295's on et22 and couldn't eliminate the rub. 10.5 et25 with 295's will absolutely work but I would plan on negative camber - as I stated above.

Here are some pictures of Frank's car with the same wheels and 255/275 tires.

Do you know how wide the AD08s run? I will be using Michelin PSS and I heard the PSS tires are a little on the wide side, but not very square, not sure how they compare to AD08s tho.

I actually have couple pairs of PSS right now, a set of 255/35/19+275/35/19(on my ZCP wheels now), and a pair of 275/30/19. I can pulls the PSS off from the ZCP and put them on the G25, or I can get a pair of 295/30/19 and use the 275/295 setup.

And I definitely agree with you that 275 on 10.5 look a little stretched.

The benefit of going with the 255/275 would be saving money on tires since I already got them, and easy fit. If going with the 275/295 setup I can have a spare set of wheels if I need them but may have to do the camber....

[slicer]

I already stated that AD08's are some of the squarest and widest tires on the market. PSS tires have a rim protector at the bead which makes them wider than average at that point. The AD08's are however more square at the tread shoulder. I would say that PSS tires are easier to fit than AD08's. If the AD08's fit then almost any other street tire will fit.

285/35 /19 is definitely too tall.

Options:

255/35 +295/30
255/35 + 275/35
265/30 + 285/30
275/30 +295/30

Good luck. The wider fronts will slightly diminish steering feel.

Why do you say that? I could buy into this if 275's were installed on a 8.5" or 9" wheel but a 9.5" wheel will provide the proper side wall support.
