Yesterday when leaving work, I got the low tire pressure warning for my rear tire. A quick check revealed a nail. Again, thank goodness for the warning, as I have about 25 miles of hwy on the way home! I purchased the tire and wheel insurance when I bought the bike in February, but the downside is that I get a brand new OEM tire. I had planned on trying some PR2's. The front tire probably has about 1000 to 1500 left on it. Would it be a big deal to put a PR2 on the front with the OEM on the rear, or would it be better to go ahead and get the OEM in the front and replace them both when they wear out? Thanks for the opinions as I am obviously a newb around here!
