I'm running michelin XZX 165's

what is the most ideal pressure for these because I know that radials run a little higher than the bias ply's that the bug came with.

I have them at 24 front and 28 rear at the moment which isn't too bad.
I did have them at 18 front and 24 rear but it felt spungy so I pumped it up a bit.

Cheers

XZX's are a road tyre rather than a semi slick, yeah ???

Road tyres you want to be pretty high... I know guys who run upwards of 40 psi doing circuit stuff with road tyres... bit of insurance that the tyre won't roll off the rim I think.

Semi slicks it depends on brand and model, but usually around 32 hot is a good starting point (they have a different side wall construction ya see)

Yes,
XZX Michelins are normal road tyres...
I had them years ago..

20 and 30 PSI front/rear is OK.. in MHO..

You need to watch in wet weather as the front wheels can lock up in hard braking... letting You slide...
If there is too much air in the front...

I can lock My front wheels at any time by hard braking..

and I run 20 psi in the front with 165 tyres..
28 psi in the rear...

I would like to run higher pressure in the front due to the very heavy steering when parking..
too heavy for My Wife...

PS: this is for normal highway use.... not racing... lol

There are many things to consider for tyre pessures, such as suspension, road or track, rim width, and so on. I feel happy running 'low' pressures - 19f & 22r on the track.

A good idea is to experiment with pressures until YOU are comfortable with the handling. Have fun!

I'd rather wear a Beetle out by racing it than by polishing it!
