I ran a fresh TKC front (Heidi rear) from Hamilton, ON out to the TLH & St. John's and back via ME, NH, VT, NY, then slab back and forth to work every day for a month (82miles round trip) and still didn't change it till spring. That was on a smaller KLR, but I'm sure you can make it from PA and back. That is unless you bike eats front tires.
