Do you mean you have 3 D rated tires and 1 E rated tire?
If yes, you need to seriously consider replacing the other 3. The other 3 are likely at the end of their life if the one blew out sitting in the driveway. Especially at the higher pressure, it will create an inconsistent reaction to bumps going down the road which could cause issues with the handling and/or suspension.
Assuming all 4 were replaced, I would go with the tire manufacturers recommendation over the trailer sticker...but the sidewall lists the MAXIMUM allowable pressure. You can go lower but not too low (manufacturer should give details on selecting pressure). Of course, if all 4 are at the same higher pressure, shouldn't be as big of a concern.
