Hi guys, I have 19" stock rims now. I'm interested in some black 20" aftermarket wheels for summer. Does anyone know what tyre pressure I should be running with 245/40-20 tyres? Should I just go with whatever is printed on the side of the tyre, I mean, the tyre doesn't know which car it's mounted on, but maybe that doesn't matter....? Bonus question regarding TPMS: In settings, I believe one can select either 19" or 21", that setting has impact on the "low tyre pressure warning"-threshold, right? Does anyone know what the treshold is, for either 19" or 21"? Again, I would like to know which setting to use, when driving with 20". Thanks.
