I’m running Pirelli Scorpion 275 45 r20 on Tesla Sportline Rims.
At anything above about 35° I don’t have any problems.
As soon as the temperature gets below that they start to lose air like crazy. For example I will fill them up to 40 PSI and then a day later many of them are too low and one was as low as 26 PSI!
Obviously not optimal for going up to the ski hill.
Firestone has looked at them but the tires never leaked when they were at the shop.
Anybody got any ideas?
