Stock Suspension, 19"x11" rear, would you run a 305/35 or a 305/30

Perfect, thank you for the explanation ?

You're welcome! Tire sizes can be confusing, but once you break it down a little and understand it more, when you do the math it all makes sense.

305/35 hands down. This is on HR springs but on stock springs i would definitely go with the 35 sidewall

I echo this, @Timmy_Jones . If you are staying at stock ride height, go with the 305/35. Lowered on springs, you could go with either one. A lil extra meat in the rear never looks bad! After seeing @travsam89 photo here, I am kind of wishing I went with 305/35 instead of the 305/30s I got. Travis, the concavity of those wheels and the more meaty sidewall looks bomb!

Yup. Looks absolutely awesome

Most people do 305/30, but if you can squeeze the 305/35, then more sidewall the better. ;D

305/35 for the win.

305/35 for the win.

is that stock ride height?

Rear is -15mm from stock presently, just casting another vote for 305/35

What did you end up going with? I'm waiting on my new set of WedsSports RN-05M 19x9.5 28mm / 19x10.5 32mm wheels and trying to decide what size to get for the Conti ECS 02's. I'm lowered on Whiteline springs 1.25" drop all around last I checked (couple days after install)

Whiteline brother. That’s what I’m on and went 295/35 in the rear! I do have a 10mm spacer but that’s just because the damn apex wheels are noisy.

That looks good! I think I'll be able to do 305/30 then. This is mine with 15mm and whiteline

A 305/30R19 has a sidewall height of 3.602 inches as shown above.
A 305/35R19 has a sidewall height of 4.202 inches.

When it's time to replace my rears (currently on mps4's 305/30) and I finally pull the trigger on femto unlock, I think I'm going to go NT555RII's 305/35R19. Lowered on eibach, I'm sure I can manage the additional 3/5 of an inch on the sidewall.

For those coming back to this thread, know that 305/35/19 is not available on Michelin PS4S or Conti ExtremeSport 02 (the ideal tires for street / Track), so your only reasonable option on that size would be the Michelin Super Sport 4S (the sock tire in North America) which has lower grip, and overall less dry and wet performance than the PS4S and the Conti; unless your focus is street/drag strip, in which case a set of low pressure NT555RII are probably your best choice.

I am running BC Forged RZ05 with PS4S
Front 19X9.5 +22 - 275/35/19
Rear 19X11 +35 - 305/30/19

From my delusional experience, the wider the tire the fatter the side wall, if all other aspects remain unchanged, not sure why or how. For example, to me, the front tire running 35 and the rear tire running 30 looks just about the same thicc'ness.

I am currently back on stock suspension as the coilover rebuild needs 4 weeks due to parts shortage.

Photos attached for reference.

front tires are clearly taller than rear.

20x10 front on 275/30's
20x11 rear on 305/30s
H&R suspension

I have wheels that should arrive in the next couple weeks, and the manufacturer, Variant, suggested 265/35 R19 for a 19x10 front wheel and 305/30 R19 for a 19x11 rear wheel.

I’ve seen this tire setup on @Spiguyver Supra YouTube video when he installed Titan TS-5s and think it looks spot on, albeit he’s lowered on Eibachs.

I’ll try to remember to post pics of my setup here once it’s installed ??

i have this setup with Variant NYSE rims. The car looks amazing and mean. When you look from behind it’s akin to a GTS. So badass!!!
Mike’s the man and knows his stuff. Makes every other setup dated.
