Steve:
If your Alpine is a Run Flat the 32psi would be fine due to its stiff sidewall. Unlike the Apline, the General G-Max has a single ply sidewall and requires the higher pressure i.e. 40/42psi to reduce/eliminate "tire squirm". I'm just shy of 22K miles on my Max and have maintained 42psi for over 19K of those miles and the ride and performance have been well above my expectations regarding a Non-Run Flat Tire! I brought along a mounted spare and will be mounting it shortly, as I arrived in sunny Fl. With the potential for quick and unpredictable "downpours" I don't want to be caught with a well worn CT:shock:
