What a difference 7 PSI makes!
Yes, I know, I haven't been as diligent as I should when it comes to checking my tires. No excuses for my complacency; I had simply become lazy as every time I checked it previously, it never lost a bit of air. However, I had noticed that over the last few weeks, the bike had been getting increasingly unstable at freeway speeds. We're not talking 100+, we're talking a comfortable 70-80 mph cruise that had the bike feeling like it was starting to wobble. Much of our pavement here in southeast Michigan has parallel grooves in the direction of travel, and I thought maybe my relatively new tires (Metzler Tourances)were tracking in them.
But the problem was worsening... Passing semis at 70 was becoming a white-knuckle affair. The wobble seemingly induced by the wind was scary as hell, and more than once I wondered if the wobbling was going to stop. So, the week before last, after a particularly commute home, I started going over it with a fine toothed comb, looking for any obvious signs of wear or play where there shouldn't be any.
The only thing I found? Rear tire was down to 29 psi. WOW! What a difference!! The bike tracks straight and true again, no wobble, no sway. Even in last week's 40mph cross-winds on the way home, the bike felt far, FAR more stable than it had on a calm day with the low tire. Amazing what a difference it makes!!
Just thought I'd share for others...
