Tyre pressures question..

[dylanp]

Can anyone give me an opinion please?

I'll be running my race car on Dunlop slicks 235/610/17 on the rears for the first time on Saturday - so far I've had slick Avon 190s on 15" on the back. The Avons worked well by setting them to be about 14psi cold (which raised to about 20psi during the race)

The car is a Marlin 5Exi - mid engined and weighs about 550Kg and I'm racing in Castle Combe..

Unfortunately I will not have an opportunity to do a test day prior - so I'll have to guess it before the race..

Any educated opinions invited.. :-)

Cheers,
Dylan

Ask dunlop would be my sugestion.

If the Avons were crossply's and the dunlops are radials, you are going to need to run more negative camber to get the best out of them.
