Toyo R888R tyre pressures

I've now swapped over from ZZS to Toyos and am out at Snetterton on Monday with LoT.  Does anyone know what pressures to run them at on track?  I've been typically going for 18 cold and 22 hot on the ZZS.

Thanks Gerard

Thank you both,

I remembered this morning that there is a race series based on the Toyos with McMillan as one of the sponsors, so I spoke to them.

They said for track use

Cold - 21 front, 20 rear

Hot - 25 front, 24 rear.

They also said that if your car has been setup for Avons you will need the car flat floored.  They charge £140+vat which seems very reasonable so I'm getting it done next week.

In the meantime I'll play around and see what feels right with the current setup.

One other point worth mentioning if you make the switch, is that it's worth checking tyre clearance on the front with the mudguard stays as one of my tyres was rubbing slightly, so I've had to bend back the stay.  It was never a problem with the Avons.

Regards Gerard

Gerard,

 

What was your stay bending technique?  I'm fitting Toyo's on Tuesday.

My worn out ZZS's have only 5mm of clearance.

Thanks,

I've given mine a tweak with the crowbar and have gained a few more millimeters before the change over.

They don't move very easily

I went to McMillan yesterday.  For the wet they go much higher; 35 psi cold front and rear, remove the front roll bar and disconnect a drop link.

For what it's worth I couldn't tell much difference between the Avons and the Toyos other than I was  getting more turn in oversteer.  My droplinks were as far forward as possible, but McMillan have moved them back.
