I was just saying in another thread how I seem to get my tyres to last well
on road courses. I've just done an 80L Indy race in preparation for the new
Cup season and all of a sudden I'm one of the worst in regards to tyre wear.
Anyone have any tricks or advice on making them last better?

I tried tearing off in third place and soon had a 5s gap over 4th but then
slowed as the tyres went and lost it all. Next stint I tried staying calm.
Only difference was I went slow in the early laps then slower as the tyres
wear. It's driving me nuts ;) Ginger's a great example of what I can't do.
In most races he'll set off on my pace or a couple of tenths off and by
halfway through the stint he's lapping way faster. If I try a practice run
lapping at his original pace at the beginning, I can't match his later pace.
I guess this means it's 'lines/controls' related rather than sheer pace.

All advice/insults gratefully received ;)

He may be right you know!  Cup cars are REALLY heavy... in our league we
regularly have two groups of drivers.. those that start 'hot' and pull away
about 13 seconds , and those that 'save' their tyres .  Guess who is in
front after 50 laps ?
        On cold tyres , if you push that fast racing line , especially on
full tanks  , for the first 5 laps or so,  then that sets you up for
increased tyre wear .. If you are smooth through the corners , however for
the first 15 laps, and THEN , with the lower fuel levels,  you push ..with
the lower weight you get  much less tyre wear  and .. the 'fast' guys have
pretty much used the ' fresh' bit of their tyres by then so the speed
differential between the two strategies is quite high !
             That's my take on the tyre wear story anyway :-)  Of course if
all you get to race in is a series of short sprints, punctuated by yellows ,
then none of this comes into play.

Assuming your setups are the same, one word - telemetry!  If you have Martin
Granberg's NR2003 Replay Analyzer, check your speed, steering and brake
traces against Ginger's.  You may be going in a bit deeper and gaining time,
but losing it back on the exits.  Your lap times would be the same early on,
but you'd be cooking your fronts scrubbing off your excess entry speed.  If
you don't have it, you should...

Wonderful program for anyone interested in finding where speed really comes
