I am looking to order the above tire and it comes in two specifications:

One for a Ferrari 812 superfast - $554.00

One for a Porsche Panamera - $534.00

Are their any differences, other than the fact that they are on two different cars?

Essentially identical. Part # 07074 has .5 32nds more tread depth that's it really

The design has to account for the Ferrari being more heavy. So if your looking for a more robust tire, that could be a slight clue.

So why not the one for $532.99? Besides, the Porsche? one has some sound deadening foam inside. The Porsche one also has lower ratings too. The Ferrari one is not an "S" either. I think you're paying extra just to have their name on the tire.

I dont think we are looking at the same tires!

Both are PS4s - 315/35 zr20 XL

Both have nearly 5 star ratings

Actually the Porsche is heavier. (4700 lbs) vs Ferrari - 3600 lbs :)

.... i went with the Porsche tire spec, since it is the heavier car.

Thx
That’s it then. I don’t own one and was looking at the wrong internet numbers. Good luck, hope that works. It is close.;)

Ok, I was only looking at the S model.
Yeah, I bought the cheaper ones last Spring, beat them pretty good on tracks, 8K, and still have 6/32nds left. I only paid $322 each on E-Bay also........... I dead getting new ones next year.

Couple of thoughts on this size. I just went through a set. Mine rub the inner fender liner wver so slightly, as in rub the head off a plastic rivet that holds the liner, but that might've only happened at full song on the track. I couldn't hear it, but could see the evidence after. Also, I went with the 110XL load rating. Additionally and IMO more importantly, this size is about 3/4" larger diameter than stock, so raises the ride height ever so slightly, which doesn't help if max cornering performance is your goal. I am replacing these with 315/30s today. The squishy from control arms and the road course killed the shoulders of the tread in just a couple days on track. I flipped the tires on the rims to get more life out of the tires. Killed those shoulders. Changed to AAD front control arms too late, but I believe that solves the problem. Rears are fine but I have the AAD Drag Pack for out back, just haven't had a chance to install. Except for the outer and inner shoulders, the rest of the tread has amazingly little wear, so not the tire's fault. Great tires, just wanted to pass this along.
