SS tires - need advice

I'm not having any problems with the SS's on my truck. Micheline XOne XDA Energies... I've got 163k on them, and expect to run them out to 300k. No issues with snow or rain - I've gotten into some places that the guys running duals had to chain to get into without throwing iron. Running them at 120 psi with a little outside wear, rotating tires at 75k increments. Most tire blowouts occur due to underinflation or road debris. Check your tire pressure and don't run over stuff - easy ways to keep from having problems on the road.

 

Find a new tire guy! Bridgestone's load inflation table pg 5 lists 120psi as the max for 445/50 r22.5. Running at 90 psi means the load for the tire is 8100 lbs max, The weavy wear pattern is most likely to be a balance problem. Think about using some kind of dynamic wheel balancer.

I've been running SS on my drives for over four years without any problems. The first set got 350k with about 6/32 left when I changed them out. I run Centramatics on the drive and the steers. The SS were run at 125lbs cold. I rotated the tires once, to move the higher wear tires to the lower wear positions.

I like doing a through tire inspection and measurement once a week. I will de-stone the tires, measure the wear across the tread in two locations on each tire, and adjust the pressures to keep them at 125lbs cold.

Too little pressure on a SS is much harder on the tire than it is on a dual with one tire running low. On a dual one tire will sort of protect the other, and there are 4 sidewalls to stiffen things up.

 

My Greatec's have 120 PSI max stamped right on the casing sidwall. I blow em up an extra 10 to reduce heat even more, and also lower the rolling resistance...

 

I have 120 psi in my xdn 2,never troubles

 

We run 110a in our ss's

The sidewalls flex more on wide singles than duals, so you get better fuel mileage if you keep them pumped up more. Also see more wierd wear marks on wide singles that are run at lower pressures. I've been using 120 lbs on mine.

 

I've got 350K, 5.5 yrs old on my original set of Michelin XDA HT.
I broken them in @ 120 and reduced pressure by 5 psi each month until I reached 100 psi and kept them that way since. My tires have worn evenly across the tread without any issues. I inspect them most times when I fuel, remove rocks and check for screws and such.

I spoke with a gentleman that supplies Messila Valley with their Michelin's and he told me that they absolutely like the new N2's. If anybody knows about this company, they are on the cutting edge in achieving better then avg fuel economy. I highly doubt they would be specifying their trucks with Michelin SS if they weren't profitable.

Personally, Bridgestone's Gantec fall short compared to Michelin when it comes to wide base tires.... no comparison.

I'll be buying my next set shortly.

 

This is true, they're the opposite of duals or say steer tires. Over inflation wears out the sidewalls. SS's are fine when used in the right application.
