When you do alignment, have the camber set to the closest setting to vertical as the spec allows. May require special camber bolts to achieve this. That will minimize the outer edge cupping if my theory is correct. Don't have enuf miles on mine since rotating and aligning to check.

Outer edge wear is a sign of improper camber, as you suggest. But "cupping" can more often be traced to improper wheel balancing. Don't assume that the wheels were properly balanced when you bought the van.

You're correct. Cupping is usually caused by toe, shocks, and balance. Mine weren't cupped, just wearing the outer rib off evenly. Wasn't paying attention when I posted before.

Just an FYI:

The term "cupping wear" is frequently misused to describe several different types of irregular tire wear, including one that is caused strictly by alignment. Even perfect round and perfectly balanced tires can get this type of wear.

Does anyone run the TST TPMS? It will allow you monitor all your tires while your driving. Increase Tire Life, and know of problem before it becomes catastrophic. Monitors temp. as well.

I run it and so far it has worked well. No problems, no complaints.

Hi Mike,
I have the TST Sytems on my Interstate. It works great and has given me the ability to avoid the risk of running a tire flat as I did last spring. Before I installed your TPMS I had an inner dual tire go flat for some unknown distance. I checked the tires OK when heading out in the morning and again at a mid-day rest stop where I discovered the flat.

Mine is the 507 model with flow-thru sensors and I have a question. The owners manual says you should get a Sensor Low Battery Indication. I had one sensor stop giving me information so I assumed it was a bad battery since they have been on my van for about a year now. When I opened up the sensor to change the battery I discovered that a bit of water had got inside and caused some corrosion. That old battery was down to 1.5 volts.

Any clue why I didn't get a Sensor Low Battery Indication?

I cleaned it up and installed a new battery and now it is working fine. I also changed all the other sensor batteries and none had any water or corrosion inside. The other cells were all at 3.0 volts. The new batteries were at 3.2 volts. So all is good but I'd like to understand why I didn't get the Sensor Low Battery Indication.

Thanks,
