Tyres tweaking 2

The whole world was holding its breath waiting to know how the coated hard tyres perform on bcg... :D

Well... as said in previous post I coated hard tyres with nails enamel but they had no grip at all (as expected); removing the subtle enamel coating from tyres leaves them softer.

I suppose they could be now considered a softer grade than hard tyres and an harder grade than medium tyres !
Those intermediate tyres works very well, they offer enough grip to race and they helps to drive good lines too.

After a good one hundred laps I decided to work the tyres in a "home made" tyres lathe (simply a dremel with a rear axle attached !!) to true the tyres and to round the wedges.

I destroyed a good couple of tyres !! the coated tyres had been destroyed by the nails file I used to grind them. I suppose those files are too aggressive to grind tyres, next time I'll use a softer sandpaper :D
