Having some good success running my tires @ 45 PSI

Wouldn’t it make much more sense to mitigate your car’s alignment problem by getting it aligned?
Besides, it’ll be a lot cheaper than repeatedly replacing tires worn out prematurely due to bad alignment and overpressure.
And with a good alignment and the proper tire pressure, your car will ride and handle better too.
I’ll let others flog you on the safety issue. But what they say will be 100% true.
