The team tests of the last weeks ...
Published on 22 February 1998 by Verstappen Info Page
The team tests of the last weeks have shown that most drivers are setting their fastest times 15 to 20 laps into a session. The cars seem to be getting faster as the tyres wear. A possible cause for this could be the wear of the grooves in the tyres, so the tyres get more 'slick-like'. The FIA is monitoring the situation and it might be possible that tyres will get under new scrutineering rules which may have a minimum groove depth.
