After riding with the Excella's for a week, and especially after my work commute yesterday I was ready to take the Excellas off the bike. There was a 15-25mph wind and it was making the bike almost uncontrollable. Before reacting too hastily, I thought that I would double check the air pressure. The front tire was at 20psi, and the rear at 28psi. The tires call for 33psi. To make a long story short, the pressure gauge that I initially used when installing the tires was incorrect. I was running on a near flat front tire. After inflating to the correct psi, the bike handled great on the road. Just thought I would share a hard lesson learned-moral of the story..don't trust pressure gauges..or deer.[sm=nono.gif]

 

Oh so true, bike was probably feeling squishy and not as responsive with low tire pressure. I do not ride every day anymore so I always check my tire pressure before a ride.

Always check with the manufacture on pressures. My pilot race inflates to 31 front and 22 rear, I would have thought the rear would be way to low but it rocks.

 

I've found that with the 603's and riding as weather permits....100+ miles/week, my tires drop 2-4 lbs every couple weeks but stabilize around 17 psi. I pump them up to 22 and they end up at 18 in the rear and 19 in the front after about 2-3 weeks. Seems odd considering the tires get pretty darn warm after a ride, however we still are seeing mid 40's to low 50's at night and highs in the mid 90's all in the same 24 hours so that might have something to do with it.
