Yokohama Tires Wearing Way too fast???

The proper tire pressure for you and your operationg may be 105, but for others it may be less (or even more). I run Yokohoma tires in every position except my steers (they were back ordered when I needed a new set). But, basically I vary the pressure in my tires depending on my load and the wear showing on them. I have run mine as low as 80 psi when I'm empty for a long run and up to 100 when I am loaded heavy (85,000 lbs gross). Also the position and tread design make a difference in the inflation. A claim of one pressure fits all does not work the best to get the most out of a set of tires.

 

Is the shop that did the original alignment the same shop that you had it rechecked? Alignment machines are delicate they need to be calibrated periodically. If it is the same shop I'd take it someplace else and have it checked.

 

Good point! Also I don't like when someone says "its within spec". I had that with my trailer and it still pulled crooked and was wearing the tires funny.

 

The TY303 is well known for poor tire wear. I had the 577 on my old freightliner and they wore very well. Don't know what to tell ya Rick besides just don't buy them again when the time comes.

I still stand by my M726EL with 500k on them and the 4/32's they have.

 

Ty577's here started out with 32/32's after 86,000 miles down to 19 & 20/32's all 8 tires. Not real impressed. Getting weird wear on two right inside shoulders on the inside closed shoulder. Maybe rotation time again I dunno. Rotated at 30,000. Had even worse uneven lug wear and same shoulder wear with previous m726's. Rear suspension bushings all in good shape, alignment checked/adjusted twice a year, tires all computer balanced with lead Plus centramatics on all 3 axles. Aired up 105psi weekly. I guess I just have bad luck with tires. Not buying any more Bridgestone or Yoko drives.

 

So is it better to run a lower psi when hauling empty? I basically run empty for my entire route (4,500 is my loaded weight) and I run my tires at 100psi. Would it benefit me to drop them to 80psi???

 

You would benefit from dropping the air pressure. With what you are doing you should be adjusting your pressures depending on your weight since you run so much empty. Basically when you run a tire with 100psi and no real load on it the center of the tire will wear more (due to it being over inflated for its current application) and the outer edges will have a tendacy to cup easier. Also the tire will be more ridged (less sidewall flex) and add in the fact that there is no real weight on the tire it will hop on the road with any small bump...this in turn creates more cupping and sometimes flat spots. I adjust mine about 2-3 times a week and check pressures daily. My cupping has stopped entirely since I started this procedure about 2 years ago. Also the wear pattern is very consistant all the way across the tread pattern.

 

Thank you. I have not had any irregular tire wear at all in the 1.5yrs that I've been doing this run, but the truck does bounce quite bad over bumps and I travel the entire length of the horrible Arkansas roadways too lol..... I'll drop the pressure on this trip and see how much better it does and report back.

Btw my truck with the tank loaded and full of fuel gross' 35,000 lbs

 

Ummm you want to try and sell this to my drivers?

 

Well just an update, I lowered my drives to 85psi and set my steers at 90psi. Truck rode MUCH better. Thank you Pullingtrucker for the advice, I will keep ya posted with my wear patterns, hopefully they will stay the same.
