Tire inflation

> I usually go 4 under the max psi to allow for heat expansion (with
non-oem size tires).

iirc, max pressure is based on a cool tire, and already accounts for heat 
expansion

> Keep in mind, it wouldn't be wise to run a 40 seires tire with little
sidewall at 35 psi around town.

exactly, a wheel repair guy (owner of wheelbendermender) suggested to even 
run them slightly higher than max rated when only driving around town 
(taking up some of the slack provided by the conservative max pressure 
rating). be sure to deflate to max before doing any highway driving.

> Also, running a higher tire pressure effectively raises your spring
rate.

more importantly, it focuses wear on the center of the tread, while the 
typical vw enthusiast driving style focuses wear at the outer edges, so i 
find that it tends to all balance out in the end.
