Erm no actually re reading my post 30 was a typo, Ive got 34 in the back but do have 22 in the front. No problems with cornering but then I didnt really notice that they were down in the low teens prior to the top up other than the squealing. Also I inflated them at the local petrol station and that guage has been thrashed, dropped and driven over so Its at best an aproximation of inflation.
