NT05R "not advisable"

2011 full bolt on l99... I bought a set of 20x9 and 20x10.5 wheels and w my traction issues I thought I'd put 275 40 20 nt05 in front and 315 35 20 NT05R out back. I place my order online and receive a call back stating that the rear NT05R doesn't meet the cars engineering specs on load index. Does this mean no one should be running NT05R on a fifth Gen bc the cars too heavy? Or is it this particular size? Thoughts? Experiences???

According to tire rack, the stock tires have a load rating of 2094 lbs (106).
According to Nitto, the 313/35/20 NT05R has a load rating of 1609 lbs.
It is light by 23%.

I have 315/35/20 NT05's on the rear of mine. The only issue is extremely poor tread life. 6000 miles and they are down
to 2/32nd tread depth but they looked really cool. Trying to find 315/35/20 Pzeros to replace them.

What's funny about drag radials (NT05Rs and NT555Rs) is how little tread there is when they're new.
I had a brand new set of NT555Rs on my car and I had to put my car in the shop to replace a tailing arm bushing. The shop manager came over to me and told me I needed new tires because my tread was down to x/xx. I laughed and told him the tires were brand new. Then a mechanic came over and explained to the manager that they were drag radials and they come with very little tread.

Keep in mind that those max load ratings are based on your Camaro being full of full-sized adult passengers, full fuel tank, full trunk full of luggage, etc... basically the max payload/weight rating. With these tires, you now have a good excuse to tell your buddies to drive their own cars, instead of bumming rides
