Truck Tires - Uneven Wear

IMO, wrong TOE ajustment.

Camber, Caste and KPI are not ajustable on solid axels

 

as I can see this is Nissan 2300, so as I remeber TOE must be 1-2 mm/m, so inspect tie rod ends first and if the ends are ok, visit aligment shop

 

Toe adjustment would result in a feathered edge across the entire face of the tire.

Push your hand one way, it goes easy. Pull it back, you can feel a sharp edge.

Camber would result in only one side wearing over the other.

Caster would result in the truck not returning to straight fast or wanting to wander.

Over inflation results in the center being worn faster

under inflation both outside edges.

Tire balance / shocks will result in cupping of the tires.

 

I would get new tires. Given the wear and age,just replace them. One of those tires lets go and you are in for the ride of your life,maybe even the last ride of your life. Something else to consider,what is the DOT man going to think if and when he sees them. Let's see,tire shops charge for road calls,miles,hours plus you usually pay more for the tires under those conditions. Get the new hides,get an alignment. The problem you have is not a tire pressure problem. You might want to talk to another tire guy because the guy you talked to is short on knowledge. Also in my opinion 110# in those tires is a bit too much. You could probably feel a dime in the road at that pressure.

 

I'd use these tires for spare wheels.

ore to retread and use on drive axel

 

ALL tires have an "expiration date".

Rubber gets old due to many reasons.

I think if memory serves me correctly, Chrysler Corp states in the owners manual for Jeeps, to replace tires after X number of years. (in fact, the link I am providing DOES SAY THIS)

here is a story from the "brother's of care care"..

I was reading on an RV forum they say 7 years because of UV break down of the tires
