31W X 10.5 X 15

[MCMIKE]

How much air pressure are most guys running with a 31W in a heavy car.I'm at #3720, with a 4-link car and have run 10-1/2-11 lbs without losing stability on the top end.I also rotate every 4-6 passes, but seems like they start to go away after 12-15 passes. The indicators look good, but hitting them hard might be killing the sidewalls.How many passes before most guys trash them?

12-15 in a car that heavy is pretty good. Putting tubes in might help the sidewalls live a little longer. The tubes will add weight but 3720lb....geeze!!!!!! Adding tubes will be like putting another deck chair on the Titanic!
