Changed By: grant Change Date: August 29, 2013 02:26PM My guess is that extra air will not help much (read my original reply)
As to the sensitivity of modern tires to camber - re inner wear - true. They are very rigid and therefore more of the wear occurs on the inner edge. If they were perfectly rigid, only the inner ridge would touch the road and the rest would be (slightly) in the air. Think about it.
To make thsi less true you might actually REDUCE the rear pressure a pound or two. But i would not.
That said, POrsche's recoemndations are desigend to dial in "safe" understeer. For my car that is 36R/29F. I run mroe like 34R/31F (cold) on the road and 35R/33F (hot) on the track As noted, extra air does not make modern tires baloon out as much as you would think - in fact very little. But it might help *some*. Might not too.
