Track tire wear... decision to make, separate autoX and track tires. Options

[yarin]

I've got a fresh set of v710s that I got onsale waiting for a full autox season, usually 2 drivers per event, 7-8 runs each. However I do want to get a few DE days in as well. I've got a second set of wheels with really old BFG R1s that are the perfect candidate for fresh rubber. I plan on attending a 2 day event at pocono raceway in April, 2 drivers, 4 x 20 minutes sessions each driver. Do you guys think this DE will take significant life off my new 710s? I'm thinking about buying a 2nd set of R compounds, Avon Tech R-As. Still available on closeout for $119/ea from tirerack. Realistically I dont see myself doing more than 4 or 5 DE days this season.

WWYD? (what would you do?)

When I was running one set of wheels/tires, I usually had to mount a new set of tires when the tread was still ok, but may not make all 8 run sessions over a weekend. So I ended up taking tires off that had more run sessions, just maybe not 8. I always felt like I was throwing money away doing that, but on the other hand I didn't want to cord a tire at the track on a Saturday and have to go home.

With two sets, I can run until I actually wear the tires out, then switch over at the track. Also for Time Trials, I usually run the 'old' set Sat & Sun morning then switch to the 'better' set for the timed runs, same thing for road race practice vs. qualifying.

So the benefits of running two sets of wheels/tires for me is:

• Don't have to change out tires until they are actually worn out, which extends the actual use you get out of each set
  
• You can use your 'best set' for the timed runs.
  
• When the first set wears out, you don't have to replace immediately, and can wait for a sale if you want to

I run AVON Tech R-As on both sets. My brother-in-law runs Kumhos on his 'practice set' and 'Hoosiers' on his timed run set. He claims he gets a second or more on the Hoosiers. He runs the Kumhos on his practice set since they are less expensive than the Hoosiers.

I vote that you go with two sets of wheels/tires. You'll save $ in the long run and may better your timed runs if you manage them right.
