I bought a set of these to replace a set of Pirelli Corsas that had become roughly hexagonal after sitting. My first impression of them was that they were pleasantly round. Then I took them to an autocross and they have comically low grip and howl like wolves under a full moon. I played with pressure a bit and was eventually able to get them to stick a little bit @ pressures like 30f/32r, but as someone else said, they grip like the retro tires they are.
I have Pilot Sport Cup2's on my GT4, and after a weekend with about 40 runs on a brand new set of those, they were worn about 50%. I guess if there's an upside to the A008P's, after a similar number of runs they still look like new. If you want a round tire that will lower limits to the point where you can safely push the car on back roads, the A008P's are OK. If you are after a modern grippy tire, look elsewhere. |

I’m not familiar with those tires but I would like to point out that the factory recommends tire pressures of 29 front and 44 rear. If I remember correctly even my 88 Carrera called for 29 front and 39 rear. Both pretty far from what you were running.

Factory pressures were recommended with 1987 (in my case) Pirelli p7 tires, which these are not, and with a particular handling balance in mind. They are not divinely revealed, let alone optimal with modern tires.
Lowering rears to around 32 improved grip quite a bit with these A008P's on the AX course. Lowering below 30 in the front decreased front grip. YMMV, but I played with this quite a bit and that's what I found with these tires, on my car, on that day. That said, I still stand by my assessment that grip with these tires is comically low compared to several other tires I have had on this car. |

Maybe consider a wheel alignmenet? A proper one, where caster and camber are set in the front. Post pics of the upper strut mounts once completed so we know it was done properly....
Run the recommned Porsche tire pressures....

A008p
I know this is an old thread but I haven't been on in ages. I wonder if Yokohama is having quality issues. I bought these tires and fell in love with them instantly. They replaced R888R tires. My 911 is a 73 with a tuned 3.6 engine. Running F205/R245. I found these tires to have better grip than the TOYO. I also didn't find any howling with the tires except at the limit of cornering. I tracked the car and was very impressed with the tires. So much so that I have another set ready to install

44 psi is way too much for the rears. We have come a long way since 1987. Go drive one of these cars hard with the rear tires set to 44psi (more like 50 hot) then air them down to ~32 psi (hot) and report back. Last edited by patina; 02-13-2025 at 01:36 AM.. |
