Novice autocrosser here, and one on a college student's budget.
For my birthday, a friend got me a set of very nice tires. That was three
autocross events ago... Just 12-15 runs. I run 48-50 psi front and 38 rear
in my Yokohama AVS Intermediates on a '95 Honda del Sol. My chalk marks
don't scrub off of the sidewalls at all beyond where the tread blocks merge
with the sidewalls.
Questions:
I know these tires are soft, but my front tires are almost totally rounded
off on the outsides after just three events. What can I do to minimize
this? Driving? Pressure? Voodoo hex?
When do they wear too far? When are they no longer safe to use on the
street? Or should I just not worry about it?
Can the tires be turned around on the rims to present a new square edge on
the outside without hurting anything?
If this really is the rate that I'm going to go through tires, should I just
leave the only reasonably rounded rear tires on the back and nuke the hell
out of the front ones, replacing them at a shorter interval? Or will I get
more net tire life if I rotate them after every event?
Finally, people say they get a season of use out of race rubber on a
light(ish) car like mine. Is this a function of some magical property of
race tires, or are these other drivers on crack?
Oh! And one more thing.. A guy in one of my classes said saw what he
thought was an autocross in San Jose last weekend near the corner of 7th and
Tully.. Anyone know what that is?
Thanks all.
Jake
