Default Tyre pressures for Proxy T1-R's?

Hi All,

Anyone use these tyres and more importantly what pressures you running them on?

I have a MY51 Bug WRX and these are currently 34 front 30 rear and the car feels skitterish!!

Brand new tyres... last set wore at the outsides after a recent airfield day (i.e outer third of tyre)

Dont want these wearing as fast!

Maybe worth get a full geometry / alignment check?

I recently changed all 4 on my bugeye WRX and the wear was the same as you, got a full setup done for £40 and my rear alignment was way out.... made a big diff to the feel of the car, worth the money!

For info i'm running 32/30

Would agree with this. My first pair wore on the outer edges. Had the Geometry set and get even wear over the whole tyre.

Tyre pressures are related to the weight of the vehicle, not the type or size of the tyre. 32/30 sounds about right, but if you do a lot of motorway miles you may want to increase by 2 all 'round. On track I would always increase pressures by 8-12lb depending on the weather on the day. The extreme cornering forces on track will roll the tyre on the rim and scrub the outer edges, higher pressures will prevent this to a degree.

Agree with comments on geometry, always worth getting done well.
