New Tires

[mercurysniper]

Greetings Everyone,

Hope you all had a great weekend!

I just recently bought some new tires for my 2000 1500 Ext Cab Z71. The original tires were LT245-75-R16 and I upgraded to LT285-75-R16's. My question is, what is the proper tire inflation pressure for these new tires? The information for the stock tires is on the drivers side door panel, but not for any upgrades. If anyone has any information I would greatly appreciate it.

Shouldn't the proper inflation of the tire be on the actual tire?

[mercurysniper]

Yes...it is, for a specified weight, which is sometimes not correct for the current application.

Look at the pressure reading on the inside of the driver door.

Most of the time regardless of tire size the pressure should be the same for your truck.

My is:

50 psi in front
80 psi in rear

I have mine at 45 psi.

I have my rears at 35 right now, it was showing uneven wear (only the middle of the tire) and the fronts are at 45, I haven´t loaded it much in a while and the threads look good.

I put around 35 in all of my tires. They hardley wear at all, and still give good ride/handling and fuel mileage. Being as I worked at a tire store/service station for 9 years, this is the best all around pressure I've found.

I always thought the pressure stated on the tire was the MAX allowable....not the recomended pressure.

The new tire pressure should be calculated relative to the load ratings of the old and new tires. What brand tires are the new ones?

Run around 35psi. This will be fine. If you carry a load or haul a heavy trailer you can bump up to 40 to 45 psi. I pull a 24ft camper and 45psi is perfect.
If you air up to max pressure you will feel every crack and pebble in the road.

Thank for all the information. BTW...The new tires are Bridgestone/Firestone AT Revo's.
