4. Aldermog's original 2009 rear Avons lasted less than 20,000 miles. The fronts look good for 40,000 but will be replaced next year when they are 6.
5. Properly inflated tyres should be 3 to 4psi harder when hot than cold. If more than 4psi they are overheating which is accepted as meaning under inflation or over loading and if less than 3 psi they are over inflated or under loaded, or both.
So Milligoons thermal imaging test can be replaced by a tyre pressure gauge. But I like his logic!
I can't believe you got that many miles, you can't be trying hard enough. Maybe you need a tune up.
On point 5, when I picked up my Roadster it was somewhat bouncy, and I had NeilM with me, we stopped and lowered the tyre pressures all round by about 1.5psi, and it made an immediate difference. This was not a particularly hot day and lots of water on the roads so tyres were not getting warm. Suspect they were slightly over-inflated from Williams. Also I have softened the front Koni's to 5 clicks and rears to 3. Which has improved the ride, but I think they need to be a little firmer so moving up to 6 and 4 respectively.
As for tyre pressures front to rear, you after right they should be biased according to front rear weight bias, and quite a few performance cars do this accordingly. I suspect a a 22psi up front and 24psi rear is about right for a Roadster. Do bear in mind that with a harder tyre on the rear if it does not get warm and you hit a more slippery surface in a bend it is more likely to break away, as the tyre wall will be less forgiving. I have experienced this in Rosie with a sudden rear end out and a resultant Fish Tailing up the road, If this ever happens do not brake but power on out through it, if you brake the rear end will come right round.
