gents,

for whatever reason, (probably been watching too much f1) had the tyre temperatures up all the way through on a drive i did today... running on standard p0's... any of you guys got any comments on what you've found to be the optimum temperature ? road running not track..

had them at 62 rear and 52 front..

cheers

Firstly I have been surprised how many miles it takes for the tyres to reach stable and high temperatures . My tyres seem to be in the low 30's on a slowish road drive. Not sure at speed.

i don't suppose i have had them that hot before due cold ambient... grip improvement was noticeable.. not that it needed that much improvement though as we know!
actually reason for the post was that when i got back i checked the manual to see if there was any details about what the best temps were, and the only thing is the 'if its red then slow down'... the diagram shows 59 degrees...

i am also slightly surprised how long they take to warm up... however you can argue its worht the wait.. !

Mine are usually upper 70s, except for the rear passenger tire that is always about 10 higher. I presume this is a sensor fault, will get it checked when it goes in for service.
Even on the track I've never seen them over 100

34 deg C when I left the house this morning and then 47 deg C front and 50 deg C rear 20km/15 minutes later. Front passenger side was 5 deg C hotter at the start and I was thinking there may be an issue with the sensor but it equalised during the journey and I realised that this tyre was the only one that had been in direct sunlight ... Would have been embarrassing if I'd complained about that :)

The red 59 deg C in the manual has had me thinking that I may have issues here later in the summer, it can get to 50 deg C ambient and hence the road surfaces will be even hotter. A local ex-SLR driver told me he used to get warning messages telling him it was too hot to drive his car during the peak of summer!
