Has anyone successfully installed 345/30/19s on the rear of your z28? I have searched and seen several posts where it has been discussed but none where it was actually done.

I’m running 325/30/19 Michelin 4s. And by the looks from what I can see it looks like 345’s would be pushing it. I could be wrong but I wouldn’t try it. Also another thing to remember is that every brand is different they all use the same number system but in the past I’ve noticed that they aren’t always the same even when the tires sizes match numerically.

I agree. I've probably pushed the fitment on stock rims as far as anyone here. I got a 325/30/R19 Trofeo R on the front 11J rim and it was Ok. As 232_ray says, a 325 TrofeoR is a significantly wider tyre than say a 325 Michelin 4 and even a but wider than a 325 Michelin Cup2.

I reckon a 345 would go on the rear rim. I'm tempted to try it one day.

You could probably do it, but you may need 12 inch wide rims in the rear.

I'm going with 325s out rear, 305 in the front in about a month.
I still have the original Trofeos, time for new rubber!!

I had 345s on the back of my 2013 ZL1 w 11" rims w zero issues. Looks awesome too, Z rears are 11.5". Shouldn't be an issue for street driving.

After I took off the Trofeo's I installed Michelin 305's and they look to small on the Z rims. I wish I had gotten 325's.

Did the same, but did the 325s out back.
Looks just right!
