Tire Size Question
Please bare with me as it's been a while since I've tried to figure out the various tire size options...and yes, I know how to use search but am looking for specific advice on my setup.
I currently have 2008 C6 z51 (non-widebody) with Vossen wheels/Nitto Invo tires, sizes as follows:
Front 19 X 9.5 265-30/19
Rear 20 X 11 305-25/20
My question is what (proven not theoretical) alternative tire sizes can I run with this setup w/o ANY issues? For instance, can I run the following:
Front 19 X 9.5 265-30/19
Rear 20 X 11 305-30/20
I'm also interested in tire recommendations in these sizes as they seem fairly limited.
Thanks in advance!

are you lowered? if yes, is it just lowered on stock bolts/lowering bolts without other supporting mods such as stiffer shocks to compensate for the decrease in travel. a minor change to a 30 series tire shouldn't cause any trouble unless you're lowered. I run 19 x 8.5 245/30/19 up front with 15mm hubcentric spacers and 20 x 11 295/30/20 in the rear with pilot super sports. reason why I run 295 instead of 305 is because the PSS's have a bigger sidewall silhouette than the Invo's. I have no clearance issues with the wheel turned all the way in either direction.

In that case you may want to turn the bolts up just a tad in the back if there's any rubbing that occurs with a 30 series tire. Having the thicker tire is a bit of peace of mind from potholes and other possible road hazzards

Nope, rim diameter increased and tire sidewall decreased to stay within 3% of the factory specs for both front and rear. 1010 tires has a great calculator to help you play around with different tire sizes and it'll feed you the differences. Goal of the game is to stay in the green in percentage difference so the computer doesn't take a crap on you when you throw the setup on the vehicle. Your speedometer will thank you
