Re: BT020 tire pressure



Hello Jan,
Yes, lower tire pressure will make the tire heat up faster, when the heat
goes up, the grip improves.
But , when you drive to slow the tire will heat up slower, during that time
the pressure stays low, and the tire will "move " a lot under the wheel
(bouncing ).
This gives an secondary "spring effect ", suspention manual's from : Ohlins
,White Power , and Technoflex, all say that :
The lower the tire pressure the harder the suspention "feels" (needs more
rebound damping ) and visa versa .
With a lower pressure the wear will be a little more ( higher temp and the
improved traktion ).
I hope this is of any help.
regards ,
Johnny Gebruers
