I just started leasing a used truck contracting for a new company. The guy before me drove it about 180k, and I'm noticing some weird things about the tires. The steers and rear drives are mismatched.
Steers for example, left is Firestone with a max psi of 120 and tread depth of 10/32. The right is Michelin with max psi 110 and tread depth 8.5/32.
Fortunately, they are all 22.5 diameter, but the fact they are mismatched seems very wrong to me. It's the same situation on the rear drives. The left steer has some really uneven tread wear as well.
How big of a problem is this?

On the steers the tread depth shouldn't cause you problems. On the drives the tires next to each other in the duals need to be close to the same or the one with more tread will wear faster. A slight difference from one side to the other or between the axles won't hurt either.What will male a difference is if some of the tires are tall rubber and other are Lo-Pro. that will cause bad tire wear and could cause problems in yours rear ends.
But if you are leasing the truck, tires are now on you. You should have gone over that truck and caught that stuff before you accepted the truck.
Well, you probably should have never signed that lease but hopefully you will be in that small group that actually makes it work. Good luck.Socal Xpress, jamespmack, sevenmph and 4 others Thank this. -

The reason for the mismatch tires is because the last guy was shoestringing. He didn't have the cash to buy a set so he bought whatever he could find that was cheap. So long as the tread depth is close on the tires that's side by side it won't hurt anything. Just looks bad.
jamespmack and Rubys0h0 Thank this. -

I'm gonna get a full maintenance record from the company so I can see what all happened with this truck. It's a walk-away lease so I'm not too worried about it. Thanks for the answers everyone.

Neither tire has a max psi. Both has a max weight for that psi
jamespmack Thanks this. -
Steers somebody said he was "shoestringing" and didnt have enough cash to buy a set. That may or may not be the case. He might have needed 1 steer tire and decided at $600 a pop. It's not worth it to replace the good one. Especially knowing no one will mount a used tire on the steer axle. So it cant even be used as a spare.
Personally I would worry about the mix matches, until it was time to replace. -
I replaced a steer tire last week because it was out of balance and the inside edge started cupping. They stopped making the ones that I had on there, and they were both 14 ply. The shop only had the tire in a 16 ply so I went for it. They said it wouldn't make any noticeable difference. Hope they're right.
