Meaty Tire Setup

What's the fattest rear tire capable of clearing CCB + suspension?

Getting a 20x11 ET43 rim... I'm sure I can get away with 305/25R30, but would I clear with a higher profile 305/30R20 on street height setting?

I'm running 295/30R20 on my GTS on PSS 4s/Cup 2 so I haven't had experience with this, but doing my own research earlier you might want to go with 305/25R20 over 30R20.

LOL going 25 feels like rubber bands like the pic. It'll look nice from the rear but I think I'll be annoyed by the wheel gap looking at it from the side.

Found this thread to confirm you can run 305/25R20 on the rear:

The 305/30R20 going to make the car too tall and probably rub but the wheel gap on the 25R is bothering me. Guess I'll have to settle for the 295 tire...

19x11.5 ET45 with a 315/30 Cup2, the OEM rear tyre from the GT350R Mustang is the best I've found for clearance.

Looks great! I'll have to keep that in mind in the future for when I need tires but might be a while seeing I only put 100-200 miles a year on.

Yes cup 2 tires. OEM 265 front but will try 285 front next year
