Tire tread depth different

Just checked my depth on all 4 of my tires (31/10.5/15) and my fronts are 15/32" and my rears are 13/32". They are General Grabber AT2's. I had it aligned last month and I bought the truck 2+ months ago with the new tires on it. Any issues and/or should I put the deeper tread in the fronts?

Big box tire retailer will recommend you to put the tires with the most tread in the rear.

 

You're probably fine as long as you're rotating your tires every 5k or so. If the treadwear is even (no unusual wear on the inside/outside of the tread, no cupping, etc.), I wouldn't worry about it.

 

Usually you always want the deepest tread tires on the drive wheels.

 

So I'll just switch the fronts to back correct?

 

Yep, the drive wheels use more tread. So you rotate them to keep the tread depths even from front to rear.

 

Ah....have to jump in here folks........on 4WD vehicles, that see 4WD use, run tires with the most tread in the front and at slightly more air pressure than you run in the rear. The reason, there is much more weight in the front with the engine than in the rear and you'll feel much better steering and overall directional traction. On load range C tires, run 32-33 psi front and 28 in the back if you mostly run unloaded. You love the traction and wear mileage! This had been my recipe for decades. Works great!

 

That is true that the front would weigh more with 4x4 and more psi would be better to compensate this weight, but you would still want the most tread depth on the rear drive wheels. The drive wheels are under much more torsional load than the front making the rear more susceptible to breaking traction, thus wanting more tread in the rear
