Only minimally

 

A complete set of tires for my semi runs $9000. I may have read a lot to maximize my investment as well as have a lot of real experience.. Please reread what I wrote and think about it. If the tire is over inflated, as your link states, it will ride on the center of the tire. Their pictures of the wear should be reversed, because if it's riding on the center, the edges will have less pressure on them, and therefore get scrubbed and wear faster. Science will prove what I stated. If it's riding on the center, the center is obviously a bigger circle than the outer edges. A smaller circle must spin faster to to travel the same speed. Being on one rim with the center carrying the load, the edges will be dragged and wear faster.

Research super singles. The same thing happens to them if they are consistently run over 65 MPH because the center of the tire grows from centrifigal force causing the center of the tire to carry the load and drag the outside edges. I have friends that happened to. If I run a small tire next to a large tire on my duals, the small tire gets dragged and wears faster. I've had to buy a mismatched tire on the road to get home and that is absolutely what happens. The small tire carries less load and is the one that slips.

 

Lance may be onto something.

In my experience, overinflated tires wear in the middle, underinflated wear at the edges.

HOWEVER, that's with me applying lots of power, and heavy braking. If you're talking trucks that carry big loads and don't accelerate or brake heavily, he may just be right.

Hmm....

 

Were not talking super singles or semis or going so fast the tires ballon in the center like a dragster doing a burn out. The logic stated on what I posted holds true in light duty truck and passenger car applications. Scuffing should not occur to the extent in this app. That your used to in a rig.

Also hopefully 9k gets you 36 virgins for that semi if running duals and 12-14 if you run super singles

 

Good quality tires run 500+ so 500 x 18 = 9000. I suggested it because he said he raised the pressure and it didn't help. I guess it depends on his application. If he isn't loading it heavily, isn't towing heavy, and runs a lot of highway miles he might try lowering the pressure. I mentioned the super singles as an example of the same wear but from a different cause. I'm sorry my suggestion upset you.

 

I'm far from upset and actually was going to say the same thing to you. We all have different fields that we have ran into issue on and forget sometimes when and where they apply to a question asked and remember this is text and you cannot read how a person says something

Not sure if the rubber you run but we run these scrap hauling our longest runs are Texas not over the country. Virgin sp464 drives 258.67

Virgin sp160 steers 419.47

Virgin sp193 trailer 226.14

Current prices as of 20 min ago. That's why I asked. Pull out DOT # 420791 we have a few trucks and more trailers.

 

Back to the op if it was not said already you could use the chalk method to see your tires foot print and determine if your pressure your set at works for your application. Somewhere on here I believe I have seen the method
