Hi,

I have a track day on Yas Marina tomorrow night. Ambient night temp is about 33deg celsius.

What should I set cold temps on tyres to?

and what should hot be?

thanks in advance

 

First off what tires are you running?

 

I'd probably start about 26 all around, then come in to the pits hot and measure again. Most tires should be around 36-38 hot.

 

Not all tires are the same

 

different for sizes too

 

2008 gt3

Pilot sport

235 35 19
305 30 19

 

pilot sport cups? Pilot sport 2's?

 

sorry for late reply, PS2

 

Go to Tirerack's site under Michelin PSC tire. Here is one of the charts. Much more info available on the site.

I've read to start at 33F and 39R for a starting point. Its the winter TPMS settings, since the tires will heat up much more then normal driving your TPMS won't read +6 or however much over the "suggested" pressure for normal driving.
