VMAX tyre pressures

[willr]

What do people do with their tyre pressures at vmax?

I was just reading some Michelin data sheets and notice they recommend quite an increase in pressure at high speed. For example 7.5psi more above 170mph!

42psi rear and 41psi front for my CL.
Usually run with ~34psi round town, stops all the rattles

I increased mine by 10% i.e. normall 39 all round and I ran them at 43 all round.

I mainly did this to stiffen the widewalls as under hard cornering the heavy nose weight can get the tyres to fold over.

Dunno - didn't bother checking...... they seemed allright on the 198mph warm-up lap......

I just stuck to road settings for VMax because it's not as though you're hammering along at high speeds mile after mile. I'd be more interested in this question if I was going to hit the autobahns and cruise at high speeds for a more sustained period.

41 rear and 39 front, based on some advice from Craig @ Graypaul.

22 front, 24 rear, same as for road use.
