Running 305's All Around
 

So I posted this on ZL1 Exclusive (FB) and I'd like to ask the same here.

Has anyone ran 305/35/20 all the way around on their ZL1's? Any rubbing up front, change in handling, change in hard braking, fuel economy, etc.? In hopes to save more $$$ in the long run, I'd like to entertain this idea. I've heard people downsizing to the 285's, but I'd rather stay with 305's.

Pro's & Con's please... if neither, how much life did you get out of them by being able to rotate the tires every 5k to 6k?

Damn... I have no idea if 305's will fit up front. I would assume not because with my current setup with 20x10 +23 up front running a 275/40R20 I have less than a pinky finger of clearance at full turn stop.

Also, I do realize it is not as simple as rotating the rims around. I understand the tires will need to be dismounted and swapped to their new respectful positions. This is a ritual I'm willing to practice, as long as it will prolong my tires life and give me more mileage.

I realize this is an old Post but it's the same question I have. I traded my SS and bought a ZL1 and I want to rotate the rears to the front. buy a new set of rears and have a 305 square setup has anyone done this with the factory Goodyear tires? Surely I'm not the only one that's had this ideal but I've been searching for a couple of hours trying to find the answer any help would be appreciated.
