Yokohama AD08R Pressure?

[sparoz]

Has anyone got experience with the tyre? I am going to be running them this weekend as the track is going to be around freezing weather. What pressure do they usually run at?

I run my AD08s around 35 psi hot.

Won't make much diff for you. Same as normal weather as tyres will heat up around the same ... Start at 31 cold

Really don't know how to take you sometimes. You can deliver your message without trying to piss me off you know . That's why I am getting training tomorrow so hopefully it will make a difference in the future!

Anyway, thanks for the tip .

This.
I run mine at 29psi cold which ends up around 36 hot, but it's easier to let pressure out than add more in.

Thanks guys

Thanks for your help. Seems to run great on 38 hot at Morgan Park - temp quite consistent, except for left rear which runs a lot hotter than the rest on the sides. I had a fantastic day with Paul - great tips on my driving.

My pressure for Nordschleife:
front 29psi (hot)
rear 28 psi (hot)

Road pressure are 33.5 psi all around.

29/28 psi hot?

Those look like cold temps to me. The hot temps would be 7-9 psi higher.

Been using on track yesterday again, 2.0 bars hot front / rear. (28 psi)

Those are my target hot pressures for autocross and seem to maximize grip for autox, built I have never gone that low for the track. How are your outer tread blocks holding up?

I have another track day coming up and plan to try 37psi front/36psi rear, which is about 1-2 psi lower than my last day, treadwear seemed OK. I am using RE11's, completely stock setup otherwise.

As spoken with local Yokohama importer, the AD08-R is made to ride as a semi slick, even if it's not (it's not caged).

2.1/2.2 hot is the right pressure for track, as I'm riding 1.8° camber on four wheels.

The tires look is great and regular all around.

Started new thread since the tires are different, but my "seat of pants" 39 front and 38 rear for my tires was pretty close to spot on . . . different tires, but still think 28 psi hot is very low at the track, probably good for autocross.
