Conflicting Brake Info Everywhere On Here

[snaphappy]

I'm leaning toward hawk ceramics, similar performance, less dust, quieter, right? But I'm going to check the racingbrake website.

I was all set to buy these only to find out they don't fit my rear RS wheels. Unless you guys know something I don't. I need 275/40/20. The Michelins only come in 275/35/20

Someone correct me if I am wrong but the ZL1's and 1LE's run 35 why can't an SS? Talk to someone more knowledgeable than me but I don't think it would be a problem?????

No particular reason the car can't - with the advisory that you might have to run them at a slightly higher inflation pressure than you do in the SS's 275/40's or even the 1LE's 285/35's.

Most likely, the tougher part is getting the car's owner to accept a tire that's an inch or so shorter and has half an inch more tire to fender gap than what he's taking off.

Yup. You'd be surprised how much people care about the fender gap.

They are a good pad for an everyday street car, but i wouldn't use them in any sort of competition/performance driving.

Just called Tire Rack and they won't even sell me 270/35/20. I would love the Michelin Super Sports, but there's got to be a reason they wont sell them to me. I think I'm just going to stick with Pirellis, I got 26,000 miles out of them. They were quiet and grippy, at least to me as a novice.

I called my local tire store. They will sell me the tires and mount them on my wheels but will not put them on the car due to liability reasons. The stock tires for our cars are rated a little higher than the PSS. As others have mentioned our stock tires are like SUV tires and are rated accordingly Pete and others run different tires without a problem. Here are the specs of both tires.


PZERO

275/40ZR20
106Y XL 220 AA A 2094 lbs.
50 psi
10/32"
35 lbs. 9-11"
9.5"
11"
10.2"
28.7"

BR , MX , BR PSS

275/35ZR20
RF 300 AA A 1874 lbs.
50 psi
10/32"
27 lbs. 9-11"
9.5"
10.9"
10.2"
27.6"
755
FR

besides the size difference in the side wall the PZERO's are rated to hold 220 lbs more than the PSS. That is why they won't sell you the tires since they do not meet the factory specs GM said these cars should have on them.


Input from others would be appreciated.......Maybe Pete can chime in and give you and me a little more info.

All that is understood. Part of what's missing is what inflation pressures that the two tire sizes (and load designations) have their rated load linked to.

To some extent, you can "crutch" the 'operating' load capacity of a "smaller" tire upward by running the inflation pressure up by a small number of psi. I've got some really old tables that are good enough for many such purposes if you work the numbers a little, but what you'd really want is the latest Tire & Rim Association book complete with the current load vs inflation tables. Not free, and not cheap.

Kind of separate is that the maximum corner weight of a Camaro is well below 2094 lbs (it's closer to 1250, maybe 1300 lbs at a WA-Guesstimated 4800 GVW), and that it's highly unlikely that the 2094 load rating is consistent with the inflation pressures called for with any trim of Camaro and tire size.

I would not be surprised to find that there are other considerations besides load capacity @ inflation as well.

I really appreciate all the technical info. Maybe I'll get the Michelins put on the front!
