People will probably flip.....but I've been running roughly 34 front and rear the last couple weeks. Going to step up to 36 here shortly to see how things feel. No - I've noticed no ill-effects in terms of traction, as I don't ride as if I were on the track (or off-road)....but I don't ride like a grandma either. Similar to my SV (I'm at 42 on that bike) - I've increased the pressures in the tires on the street to gain some longevity. At street speeds I have yet to notice any loss of stability.
Believe what you wish. I've run the SV at 42psi this entire season - that includes a week at Deals Gap and several other sporty days. Absolutely no issues with traction and/or safety. It says "max 42psi" on the sidewall for a reason.42 psi is insanity.
Why not just run touring tires?Again - I am NOT running 42 in the SMC. People seem stuck on that. If you're referring to low 20's in the SV....I've never even heard of that, on track or otherwise.
Why would I care what a racer or race tire distributor says? That's not my application - and yes, low 20's on-track makes sense. Not on the street.
Clearly - for total performance, lower pressures are better to a point. If I were racing or track riding, it'd be a different story. On the street - I'm simply not concerned with ultimate cornerspeed.
