Wet Tyre Pressure Settings?

[ScottHughes]

Well it looks like a wet day at Donnington Sunday so I could do with some help referance tyre pressure's I know slicks need to be about 14 cold but what about wets? Please help.

Thanks

What are you running? For my Avon radials I run between 20-22psi depending on conditions

[ScottHughes]

Avons? but dont know if they are radials or not? I assume it won't make much differance on pressure's thanks. Good job I asked as 14 would have been a bit low!

What are the size markings on the tyres, if they are something like 6.2/21x13 (width/ diameter x wheel diam) then they are crossplies, the radials would be marked more like road tyres.

The crossplies will need lower pressures than the Radials. I think the radical manual says something like 15 or 16 ?

Radial hot / running pressure should be similar for wets and slix. Obviously for wets you will need to start the cold pressures a little higher as you won't generate the cornering forces to get the tyres hot.
