245mm F and 285mm R ?? Anyone ever drive on Federal 595RPM's?

G-SPOT

Hi.
Fitted 265-35-19's front and 285-35-19's rear about 4 weeks ago on my 2011 370Z.
First drive out car felt like tyre pressure was to soft... Contacted the tyre supplier's and got told to take pressure up to 3 bar / 43 psi, did that with no joy. I played around from 2.2- 3.5 bar/31-50 psi and no difference.
I did about 600km's/370miles to scrub of the new tyre look to get to the sticky part, some hard driving,cornering, braking and drifting at it as well.
Bottom line they are awesome if you like going side ways cause there is no grip, unpredictable, super soft sidewall, if you drive with vdc on your skid light flashes on every corner you take and hard acceleration, horrible under hard braking, wet roads are a blast( side ways) on the positive side they are quiet!
I use Federal ss595's(595) on my daily drive 2004 350Z and have done 32 000 km's/20 000 miles so far and loads of tread left,I have used about 4 sets of 595RS-R's on my supercharged and track 2006 350Z awesome grip wet and dry( wish they made 19 inch in these) I even use their mud terrain 4x4 tyre on my off road truck, so I like the brand-just not RPM's.
I now own tyres that's over rated on their website( misleading)
Federal Tyres - Federal Motorsports - 595RPM
and cant/wont sell to anyone, learn from my mistake and stay away from 595RPM's!
Saving up for set of RE-11's.

Cheers
