I usually go 5 or a little more LESS then the MAX on the tires when warmed up.
If our cars are rated at 35 but our tire holds 50 max i would not think that using the recommended rating on our cars would suit the tire. Its only a little over half. Dont sound right to me.
Mine are rated at 40 and i have 37 on the rear and 35 on the front.
Tire blowouts are more common on UNDER-inflated tires. I think your right on the money.
