Is anyone else having this problem with their tires?

[disc42]

I have a 2009 Genesis 4.6 with Pirelli zero nero all season tires.The tires have about 5000 miles on them.For some reason the rear tires are wearing in the middle but the fronts aren't.All tires are the correct pressure 33psi.Anyone having a problem like this.

Weird... I am very curious to see other responses. Sometimes a tire and a car just don't get along. For example, the Michelin Pilot Sport A/S did the same thing with a BMW 7 Series, but no other tires did it. And, folks with multiple cars did not have the center wear on other cars with the Pilot A/S tires. Folks dropped the tires to low pressures, but nothing solved it.

Did you verify it was properly mounted. Outside of tire is Outside, not inside?

Centre tread wear on a tire is usually caused by a high air pressure, assuming everything else is OK. Try lowering the rear air pressure a couple of pounds.

Also try using another tire pressure gauge just to make sure the one you have is giving you correct readings.

Do a "hot" tire pressure test. Go for a normal length drive and then quickly check your tire pressures. Normally you want to know "cold" tire pressures (vehicle has been parked for 3 or more hours) to properly inflate the tires. If some condition exists though that is causing excess heat buildup in the tire then the "hot" pressures will be extra high. So if your "hot" rear tire pressures are more than a couple PSI higher than the "hot" front tire pressures, I'd look for mechanical issues:
a: too much weight in the trunk

b: brakes dragging (hold your hand close to but DON'T TOUCH the rim or any other metal part, compare temps radiating from the front brake rotors to the rear brakes; the fronts ought to be warmer)

c: incorrect rear toe (alignment) leading to tire scuffing. The tire will probably have a sawtoothed shaped wear pattern as well. Run your palm over the tread as if you were petting the tire; if you hand moves easily in one direction but catches on the tread blocks in the other direction you have feathering wear typical of toe alignment issues.

Tirerack reviews by owners of heavier, rear wheel drive cars (Equus, Jag) complain of short treadlife. Other smaller car (GTI) owners say long life, and many cry about noise as tire wears. This is probably a design issue across the different sizes. So it could be that the particular dynamic performance of the smaller Pzero nero is tuned for smaller, lighter cars (most of the market) and leads to better performance. It kinda makes sense for an Italian tire maker to tune their tiers toward smaller performance cars.

Is it also possible, though unlikely, that there could have been a material or manufacturing/vulcanizing defect that resulted in the center rubber being softer and more susceptible to higher wear.

Some tire makers use different compounds in different parts of some tires by design to optimize grip vs. wear across the tread (Michelin's Pilot Sport line), but I'm not sure about the P zero neros.

I’ve had Generals G MAX-AS03 225/50ZR18 since 06/2012 with about 8K on them and still can still see the Visual Alignment Indicators and the Replacement Tire Monitor indicators in the center of the tires show no wear at all.
I just rotated the tires front to back since they are rotational tires.

The tires are filled with N2 to 33 PSI. One of the advantages of N2 filled is there is almost nil pressure increases or decrease with tire running temperatures.

Untrue, Charles Law applies to nitrogen.
