Goodyear Eagle F1 Supercar 3. About the same grip, way more life. May not get the best times, but close and you’ll save $.



These are my PS4S after four 20min sessions back when I had a Cayman S. This happened 3 times. Others swear by them, so YMMV.

I'm curious to know what tire pressures you were running. I've been through two sets of PS4S, running 35-36 hot, and have never seen anything approaching that tread separation. Maybe I'm just not driving hard enough :-).

Or maybe I know nothing about proper tire maintenance or proper cycling Track hot: 32/35
Track cold: 26/29

Same pressure for all other tires I’ve used. Front/rear camber: 3.0/2.8, Sway bar: Med/hard. I do have some of the best production car times at my track.

I’ve read a few more people with similar results, but most people like them. I usually don’t drive the GT4 on a wet track either. PS4S are better in the wet than the Goodyear.

My home track is Gateway in St. Louis. It’s been known to be hard on tires.

Similar setup to mine, I'm at Summit Point, WV about half of my track days. I'm running BFG R1s this season, so the PS4S will be mostly rain tires. I'm sure they'll see some dry use, though. I'll keep a more watchful eye, now that I've seen that photo...

That isn't too bad, seems like they would last 2 weekends at COTA? How did you like them overall? Did they handle heat well throughout their life? Good grip until they chorded?

I'll bite- what mount is that?

Tackform. They make great mounts.

Same here. I actually ran slightly quicker on the Goodyears at Gateway in Oct but ambient temps were much different and I'm still learning the car and track. Maybe just learning curve. I'll try the Bridgestone's again when if/they come available, but until them I'm perfectly happy on the Goodyears.

Oh, and I've tried to chase CyberGeorge around that track many times. He is VERY fast...and smooth.

...an obvious exaggeration but thank you

What sizes are you guys running for the Goodyear Eagle F1 Supercar 3? Are they the same as the RE71?

I am running 19" wheels and will need some new shoes to replace the RE71 - thanks!

CyberGeorge

On 19x8.5 and 19x11 you can run 245/35ZR19 and 295/30ZR19 and you get a bit more patch in the rear. But you may need spacers and lug bolts depending on offset. For my ultra leggera I got these:

Thanks lot!
I checked and my wheels are actually 19" OZ Ultraleggera HLT
8.5 49mm offset with RE71 245/40
10.0 40 mm offset with RE71 285/35

CyberGeorge

I used to have the same rears. In that case, get the 285/35ZR19 rear. No spacers or bolts needed. Same fronts. You’ll get a lot more track time out of the tires and if you’re not racing, doubt you’ll notice much difference in grip. My times stayed about the same in my local track, but there are other factors of course, and I’m too chicken to run hard when wet, so I can’t speak to wet performance.

Sancho22

awesome - thanks!

Lot's of tire talk lately. Just had the SC2's installed (N1 compound and heat cycled by TireRack) and really struggled in wet/damp conditions this weekend at Autobahn CC North Course. Was not so much my inexperienced wet driving (finding the wet line is an experience), still slipping the wheels when short shifting on the straights was a surprise. Throwing it out there for what it's worth. Loved them in the dry last year and hope I get the same grip I experienced previously in my next outing.
