Will 325/30ZR19 tires fit on the rear of the CT5-V Blackwing with the stock wheel offset?
 
Agreed...https://www.michelinman.com/auto/assistance/warranty

If Michelin makes them you could try them out and if you don't like them for any reason and it can be as simple as too loud or bouncy (it doesn't seem to say anything about fitment changes). I've actually done this same thing at discount tire on my MK6 to a 235 45 17 wouldn't clear the front and rubbed under max rebound. They took them back and I went with the stock 225 45 and went with 215 45 and was able to rotate the rear easier for autocross. I didn't wait longer than a week or so.

The car is sitting a bit uneven bit they are amazing!

That is killer... almost like it was made for those tires. 😯

So, no rubbing whatsoever?!?

Are your fenders rolled?

Have you checked at the extreme yet (e.g. with two adults in the back seat, hitting a large depression at speed, etc.)?
 
Car is lowered?
 
As posted on a previous thread, I did the same thing: Michelin Pilot All Sport AS4 325/30/19 in the rear on OEM wheels with 6mm spacers.

No rubbing at all of the fender. The inside edge of the tire sometimes just barely touches the fender liner -- but just barely & only under severe loading.

I ran Toyo R888R on my ATSV but I’m curious to know what size tire the 4BW will take without spacers?
 
Personally did not think you could fit 325 without it looking like a hammer hit the thumb with the OEM granted they are Toyo and not PS4's, and based on this old thread it looks great and lowered. @Hurley24BW

Watch that unsprung weight according to AI. someone said;)

Aftermarket forged aluminium wheels can/may be heavier than your OEM's.;)

A few of us miss this back then, glad you brought back @ajtx00

I just put Toyo R888R 325/30/19 on my stock CT5 V Blackwing wheels with 6mm wheel spacers and it works! Hooks like a champ!
Where did you get the extra extension on the front splitter? That looks great.

Hi, I had some questions on your setup as I'm looking at doing something similar.
  • What was your setup (tire size, wheel offset, etc.) for the front?
  • With the front setup, how is the tolerance for rubbing in the wheel well?
  • For the rear, you stated the inside edge of the tire just barely touches the fender. Do you think there's enough tolerance for 3mm more outward poke on the tire, and 16mm outward poke on the wheel to not touch the fender?

Did you get longer studs?

If not, did you get 7 full 360° turns on the stock studs?

I would not want to tempt fate with a high HP machine...

OE 19" wheels with OE size 275/35

Same as stock bc using the OE sized tire on OE wheel so no rubbing.
  • For the rear, do you think there's enough tolerance for 3mm more outward poke on the tire, and 16mm outward poke on the wheel to not touch the fender?
I do not think that will work at all. As it is with the spacer and 305/30 on OE 19" wheels, the tolerances are super tight.

Using the OE studs like others & have not heard of any issues. If I were tracking the car, then I'd definitely use longer studs. But I'm not tracking her with AS tires. YMMV.
