Adding to this, i've been driving about 250/300 road miles and have had no issues with the VS-5S alloys and tyre pressures.

But as soon as I went on track yesterday, I had 3 of the tyres gain pressure normally under heavy load. Unfortunately one of my rear tyres was losing air quite rapidly.

I'm running Cup2's instead of the 4s's on 19x9.5" ET28/19x10.5" ET45.

Had the tyre assessed, no air bubbles or punctures. Had the tyre resealed to the rim, valve needle replaced. Still had the same issue repeat on the very last session. It might not be an alloy issue but a TPMS seal but concerning to see. I've bought a new TPMS and taking it to another garage today to see if they can spot anything.

Anyone else got any trouble shooting tips?
