GBS Open Day

Had a great run up to the Great British Sports Car factory.  

Went the back roads so it was an hour each way.    Lots of mates there and cars  there so had a happy 2 hours chatting, admiring cars, doing emergency repairs to one of the cars, drinking coffee and eating cake (lovely )   


This time I used the tyre sensors and pumped the tyres up to19psi.   During the trip I was interested to note that they fairly quickly warmed up and settled at 20 psi for the front and 22 psi for the back for the whole of the rest of the day.   It's very subjective, but I really did feel that the ride was a lot smoother and less shake, rattle and roll, but this was a different set of roads to my last trip so it may not be a valid comparison. 
However, it does show I have probably been driving around on under-inflated tyres for 3 years  because I believed the Halfords gauge.    
About half way there I flicked to the 'Tyre Temperature' display and found that the two front tyres and the offside rear had settled on 19C which is nice.  Unfortunately the rear nearside was 3C hotter than the others.  And this differential was maintained all the trip.   I was coming up with all sorts of reasons (rubbing brake, tight wheel bearing...) until one of the lads pointed out that the exhaust gases were coming out just in front of that wheel so the sensor was probably being warmed by that    I think I will file Tyre Temperature under 'things about the car I would rather not know).
