PSS's are available in UK for 19" OEM [225/255] and OEM up 1 size [235/265].
You would need to check to ensure correct load rating if moving from RFT to non-RFT.
Not sure but I think non RFT need to "XL" with a higher load index # than RFT equivalent. Other forum members please please chime in on whats available / recommended for e9x wrt 19" non RFT load index.
Just a shame Mich PS3 is the only option for non-M e9x 18" oem sizing. Bah humbug !
