I ran 42/47 f/r for a long time, but have reduced that to 38/44. I ran that fully loaded from San Jose to CCR in Wyoming and back with no issues. Running this pressure provides a little better traction in damp/wet conditions which I like having, especially after totalling my 02 LT in 2004 in the rain. Tire wear doesn;t seem to be noticably reduced at this point.BeemerBob said:I'm planning a trip (solo) to AZ from CA this week. Bike will be moderately loaded. What is the recommended tire pressures (running Metzlers)?
