305/30/19 or 325/30/19 rear tires

[S550Mark]

I recently ordered a set of forgestar wheels in 19x10 and 19x11. Im about to place an order for some Continental Extremecontact Sports. Im on the fence on what rear size I should go with.
Wheel size is 19x11 +50 and I am lowered on Eibach Sportlines. I know 305/30's will fit no problem but if I can run the 325's I'll go that route. Curious to see if anyone has a similar set up and what works best.

Mine on 325's

No rub, I have about -1.2 degrees of rear camber in to clear.

I just replaced my 305's with 325's this week. No issues and fit well. I am not as low in the back as you guys are though but have my rear camber around -1.7

Looks good! I’m running the same in the rear now with my PP wheels on a 1” spacer. I’m going to get it re aligned though once the wheels and tires come in.

Judging by those springs you're concerned with looks over performance, but a 305 will fit an 11" wheel much better than a 325.

Ok sounds good. I have a feeling the conti’s run a little wide compared to say Indy 500’s or something

I know this was a while ago but wondering how the fitment was with your stock PP1 wheels and 305 width tires? Tons of people say it’s fine and others say it isn’t. 35x12.50 wide tires go on 9” wheels all the time on trucks as look great. The stock rear wheels are 9.5 so you would think a 12.00 wide tire would be perfectly fine?

It might hold air but it will handle like crap. I would not recommend it.

Agreed.

Truck trucks running wide tires on a skinny rim there’s always a lot of sidewall to take up the difference. That’s why they always buldge.

You don't want that on a low profile tire. It will handle like crap and feel really squirmy.

I would ask what are you going to run up front. I had the Conti SCE and love the tires. I run a 285/35/19 which is 27.1" tall. Which is quite a bit taller than either a 305/30/19 or a 325/30/19. A 305/30/19 is 26.3" tall and a 325/30/19 is only 26.7" tall. So I wanted to run a 305/35/19 which is 27.5" tall, pretty darn close to what a PP1 car (which my car was) has. Unfortunately a 305/35/19 is not offered with the Contis.

I ended up with Mich PS4s 285/35/19 front and Mich PSS 305/35/19 rear (GT350 size). However, if the Contis were available with a 305/35/19 I wouldn't hesitate a moment to get them again.

Yes a 325/30/19 will fit on a 19X11 wheel, but it won't be optimum. The 11" wheel is the minimum for a 325/30/19 but if you see the charts of this tire the specs are given with a 11.5" wheel. That would be the minimum for optimum sidewall support.

IMO those 305’s on the rear look a little stretched

Continentals run a tad smaller and are more rounded on the edges v.s. a Michelin or Falken.

Those are Mich 305s. Same size as GT350.
