This is a very odd location for rubbing, at the 3 o'clock position for both rear tires. Many on here say that 285/35 would fit just fine with no rubbing. Well, I got A LOT of it. Car is lowered fully on stock bolts (didn't look that low on stock tirres) and it rubs on any bump on the highway. Took it to the track and its constant rub on any hard turn. More so on the driver's side. Good thing is it is no damaging the tire at all, bad thing is its going to eat a hole through the wheel liner quickly. What is behind the liner at this spot? can I somehow push the liner further back? I don't know if raising the car back up will do much of anything but I could try if no other choice. I didn't get a picture of the passenger's side but it's obvious that's where the rubbing is, just weird it happens when that side lowers.
Help please, it is a very annoying and embarrassing noise. It also rendered my track videos pretty much useless due to the constant noise.

My 295/30 MPSS rub on the front of the inner liner, about the 10 O'clock position. Only rubs on large bumps in the road. It is lowered on stock bolts about 1 inch. I have a small hole in both liners.
Bruno,
I had a similar issue, except my rear wheels were too far "forward". Did you have a 4 wheel alignment recently?
Have someone who knows alignment on C7 vettes and possible re-align the wheels "forward".
To do this right, have your alignment person remove the rear shocks and leaf spring, and check for interference. Set the camber (negative), etc. accordingly. Hope this helps.
285 30 20 is what should be in the rear. The 285 35 20 is 1.2 inches taller, plus you lowered the car. Sure its gonna rub.
Well actually the tire is only 1/2" taller. It is only taller by the radius, not diameter of the tire. Normally people don't expect to rub at the front or rear of the tire but rather above it so I was a bit thrown off.

It is fairly close to the front too. I think a 27.8" tire is just the limit with these cars. Here is what I found out for future reference for anyone:
Pulled my driver's rear wheel off and checked the liner, wore through about 1" by 1" hole . No problem as where it wore has a plastic piece behind it. Pulled the liner out a bit and realize its the outside wall of the little trunk cubby. Definitely don't want to wear a hole into that.
Car was lowered on bolts all the way, I raised it to about 3/4 on the bolt. This effectively raised the rear fender to 30.5" on both sides. If I remember correctly I had 29.75" before the change. So that's quite a big jump. Drove a bit excitedly and hit some bumps on the highway, no problem!
Looks tall here but from far it looks fine.

My 295-30-20 Michelin PSS (BMW Spec) do not rub ( in any setting) with my car lowered all the way on stock bolts on stock wheels. Have Z51 w/mag ride. No issues before and after a recent alignment.

I commented only because others in this thread commented that they also had rubbing issues with this 295-30-20 MPSS.
I always check widths and diameters of possible replacement tires before I buy. The real challenge is when you go with aftermarket wheels and the varying offsets.
I am rubbing with my stock 19" rear tires on the driver side. It is rubbing against that accessory block in the back of the trunk that sticks out with the wheel liner on the driver side only. Only rubs when I hit a depression in the pavement at freeways speeds. Nothing I can do about, other than selecting a slightly smaller tire.

Same tires. Same car. Two alignments. Track and street. And rubbing with the car lowered
