Short answer: I would love to give you a specific, 100% guaranteed accurate answer but truth is I can't since you don't include the type of vehicle (year/make/model) or what size tire it is.
I have to assume since the recommendation is 80 psi that this is an E-Load (10-ply) light truck tire, in which guess, your damn well right you had better put 80 psi in it. The air in your tire supports the weight of your vehicle including whatever you are carrying in it. Think of the tire as a container for that air. The more air, the more you can haul.
Not enough air can result in a tire failure.

This could be right depending on the purpose and design of the tire. Most normal cars and trucks are around 28-35 psi. The tires on my F-100 have a maximum of 50psi.
The tire should have the inflation pressure on the sidewall. Make sure this "80psi" is not '80kPa' which would be approximately 11-12 psi.

If you have a 3/4 ton truck or van that would be quite common for a pressure. Don't guess. Read the tire placard on the door jam that tells the tire type and cold pressures. Make sure you have the correct tires (as per the label) on the vehicle before you inflate them. If someone has put other load rating tires on that vehicle prior to you and you start to pump them up to 80 you could have a real problem.
If you have the correct tires on the vehicle then set the pressures to the placard recommendation. Over inflating could cause the tires to burst, under inflating makes then run real hot and could lead to sudden tire failure.

80 would be for a very heavy truck. who recommended 80 psi? if its a car tire, no way. more like 28-30. look on the label in the door jam, it should usually tell you how much air to put in the tires. the "max" pressure on the tire is not the recommended pressure. and for cryin out loud, 200 psi would be dancing with death. dont do it.

actually have run into this- 80 PSI sounded high to me also. But that is almost standard PSi for your 3/4 ton trucks with D or E rated tires on them. and just guess they are road tires also aren;t they. Yes keep them that high so you can actually get the high life you bought the tires for.

If that is the recommended tire pressure...Yes.
Not enough pressure will cause the tires to wear on the inside and outside edges. To much will cause wear in the middle. Always go by the mfg.'s recommendations.

If you have purchased aftermarket tires, the information on the door jam is redundant.
The tire will say on the sidewall ---
Max PSI @ "X" LBS. That means weight per tire.
Unless you are packing excess weight 10 PSI under maximum pressure is adequate .

this is easy look on the side of the tire by the rim and it will tell you what the tire pressure should be.You might have to squint a little as its small print but its there
