Not sure if anyone can help.

I have some standard Dunlop D218 tyres on my cbr. Now, in the book it says the tyre pressures should be set at 42psi rear and 36psi front, which to me after the sv seems odd (but i dont know anything really).

I cant find anything on the internet that can confirm this is right or what other people recommend.

I checked the pressures last night and they have been set WAY off what the book says by the dealer so I dont know who is right.

Last night when cornering relatively quickly my rear tyre had a MASSIVE slide, there was nothing on the road and the tyres now have 250miles on them with very little left unscrubbed on the edges to cause the slip, could crap tyre pressures cause a tyre slip like that?

I assume the tyres are reasonable sports tyres as they are fitted on all cbr's and the likes of the kawasaki zx10.

Any help on this would be appreciated as I know theres some fairly knowlegable tyre type people on here.
