I'm (under) employed in the auto industry, so you can guess how well my finances are doing this year.:D So I have the funds to run one race this year with all my college friends, the Ore to Shore in MI's U.P.. The race course consists of a few miles of pavement (6 total?) and maybe 22 miles of sand, deeper sand, wood chipped hills, and about 300 yards of hardpack. My bike is a '98 Trek 8000 and I weigh 175 lbs. I live in S. MI where the trails I ride on are clay, gravel, and loam. I have no sand on which to test the tires myself before the race.

Currently I'm running a Maxxis Crossmark on the rear and I have the OEM Bontrager Revolt ST2 on the front. The other option for a front tire I have is the Hutchison Spider 2.3 air light I have on the front of my SS bike.

Since it's an old tire, here's a pic and data on the Bontrager Revolt ST2:

So here's my issue: Last year I missed my goal of completing the 28 mile race in two hours by just two minutes. In addition to training harder this year, I'm looking to maximise my set-up w/o spending any money. The difference in volume betwen the two tires is significant. I run the Revolt at about 38+/- PSI while I can run the Spider down to about 28+/- PSI w/o fear of pinch flatting. Should I retain the revolt ST2 at 570g, 2.1 inches wide and fairly dense tread or should I go with the Spider at about 680g, 2.3 inches wide, and fairly open tread?

Bueller? Bueller?


Shameless bump and title change to hopefully get more people to read the thread and throw a few opinions my way.
