Well after reading all of the comments... I decided not to go budget but I went for 4 brand new Uniroyal Rainsport 3's.
£76 each from Lovetyres on the net.
I have put 37psi in the front ones, however they still look a little low. I know the engine weight has a lot to do with this but surely they shouldn't look less pumped up than the rear?
that was a good price.
34 psi at the front and 32 at the back should be fine. 37 sounds like a lot, maybe try again using another guage they can vary a lot.
