Try upping the rears a lb at a time. Some peeps reckon 34 all round, I like 33/31, see what you are comfortable with

 

I put 34/32 on my 03 WRX, trouble is though, it seems to feel great when you first drive it after the pump up....then a couple of days later it seems back to where they were....I know i dont have a puncture but they seem to go down a PSI or 2 every few weeks....

I think that 28 (even on the back) is pretty low though.

 

i will try to increase backs a bit,28 seemed perfect for bridgestones
thanks,martin

 

To be honest if you thought 28 suited then it may be ok, i run mine higher because i live in milton keynes, the land of buggering tyres quickly....running a higher pressure makes them a little stiffer so slightly less flexible.

If you dont have 100s of roundabouts to content with then i would say up the backs to 30, no more.

 

28psi does sound a bit on the low side.I run all my tyres at 35psi,never had any unwanted side effects.Im asuming the tyres are not literally brand new?
(still got surface sheen) which will obviously effect grip level.

 

they have got 2000 miles on them so well run in but the side walls seem softer than bridgestones
thanks, martin
