I have an experience ( and questions! ) relating to tire pressure. I have
some tires, that are not very highly rated ( $100 or so ) with a 60,000
miles warentee ( read " not sticky rubber - family style M+S tires " )
and I was up the canyon driving the other night. I drive FAST through
those curves, and I could feel my tires loosing grip around most of the
turns. When this happened, it was a sort of skidding grab-jump-grab-jump
kind of traction. It was sort of disconcerting at first, but I got used
to it. I was wondering : Do all tires lose traction like this? I thought
tires would actually skid, not bounce-skid...? I drove the same tires
through a yellow light/left hand turn about 40-50 mph on cement, and they
slid (did I mention that they squeeled? they did. ) the way I would expect
tires to skid. I feel that it is because of the cement, and that for
whatever reason, it doesn't have as much friction as asphalt (Sp?). Am I
after this little mountain escapade, I looked at my tires in the morning.
They all had little bruise/scrape/burn marks around the first couple or
three inches of the sidewall. Was I actually folding the sidewall over?
I was running street/dirt road pressures of 35 psi. Usially if I go
'mountain racing' I jack them up to 40-45. Would this have helped me?
Should I just go spend the cash and get some good Z rated tires with
stiff sidewalls? Or should I keep trying to play the 'beat the 60,000
mile warentee so I can get new tires for free game'?
thanks ( for reading this book^H^H^H^H long message )
