Just fitted the 18s ( will get some pics up ) and the tyre guy put 40 psi in them ![Confused](https://www.scoobynet.com/images/smilies/confused.gif)
He said thats right but who am i to argue so i though i'd better come here and ask the question
225 / 40 ZR x 18
Anyone care to set the record straight![Thumb](https://www.scoobynet.com/images/smilies/thumb.gif)

As its quite a broad title does anyone know what the best pressure is for 225/45/17 and 215/45/17 as well?
So thats
225/40/18 =
225/45/17 =
215/45/17 =
So thats
225/40/18 =
225/45/17 =

As in does it work for you? What size tyres are you using? My local Subaru specialist said that the standard 16 and 17s work best with 28psi all round. Not sure if thats right but I tried it and it drove well but didnt feel as sharp or quick.

Played this game....
Tyre maker says see car manual.
Car makers say ask tyre manufacturers.
So I run +2 psi F & R over Subaru's advised pressures, more on track.
225/45/17 or 235/35/19

So thats
225/40/18 =
225/45/17 = 32 front / 28 back
215/45/17 = 34 front / 31 rear Bridgestones RE50
215/40/17 =
I did 10000 miles and got very even wear at these pressures. So would you lower the pressures slightly for a wider tyre i.e. 225/45/17? I have just bought some Vredestein Sessantas and no idea what to inflate to so just kept it the same.
