pilot sport 3's pure's are rated the same thats why I need to pull the finger out and set mine up, its only after setting up and riding my dads R1 I realize mine is off.
yeah i hear ya but do you think michelin recommends those pressures allowing for pillions & luggage ? i know the honda owners manual allows for rider, pillion + baggage weight and i believe pirelli do the same.
the thought process for this fellow was - the correct pressure for a motorcycle tyre is the one that pushes equally back to the applied pressure force during riding - weight is a force not mass - therefore a track rider pushing hard into a track corner can apply a different "weight force" to the tyre compared to a weekend rider that applies a lighter "weight" to the tyre therefore both people would have a different correct PSI in their tyres - so what im saying, the PSI indicated on the side of the tyre is the "maximum" allowable weight force for that tyre not the "actual" weight force - the weight of the rider/pillion/baggage, the type of riding being done and the ambient temperature of the track/road will all alter the correct PSI for a given bikes tyres - therefore im tending to disagree with this fellow - but im open for discussion on this if anyone wants to jump in.
Notice you get less miles on your tyres? And is that cold? If yes then I wonder how high they are when your out having a blat on a hot day
Having less pressure in the tyre will result in a more even wear. I have used the above pressures 34/34 or 26 in rear for about 5+ years and never flat the center of the tyre before the edge. I posted this before but talking to Mark at MH racing who was a suspension guy for pro racers and equivalent moto gp racers in the 70.80's who was telling me this. Tyre manufactures want you to use their recommended pressure so you use the tyre quicker. Tyre fitters will say the same as they want your service to buy more tyres and fit them This is only what I know and my view. if you are under inflating the tyre too much then you will get more tyre ware. just think on a hot day running 36/42 rear cold. And how high they get to when having a fun blat out. more like 42/48+ rear. I have been told to run my kit car at 32 front and 32 rear. Wore out my tyres in half the time and now run 18PSi front and rearl. OK it weight's 650KG with a tank of fuel. but showed me recommended tyre pressure is not always/often the right pressure for bikes or cars

I've had mine set at 34f 38r on my Sportsmarts but she is now feeling slower and squidgie so back up to 36f 40-42r which I run all last year and my rear lasted 4500mls and the front's still going strong
yeah thats why I run a few psi under what they say here is also a nice little guide that can tell you a lot about the way your bike is running Motorcycle Tyre Wear Guide - The different types and what causes them
I thought this thread is about tyre pressure with "normal" tyres and not "street legal racing tyres"? PIRELLI INTERNATIONAL
I agree with your conclusion. Motorcycle manufacturers always go into the subject of air pressure in great detail in their vehicle manuals as well as the tyre manufactures. In my opinion it is essential to use the tire pressures recommended by the manufacturer of the bike and not to play around if you are riding on the road and not on a track. On a track day it is a different story, maybe to start with 30/30 psi or 32/32 psi for a street bike. But everybody might have a different riding technique and has to find out the right tyre pressure for themselves. MICHELIN Power
1. No, depends on my riding, but under normal conditions I never had a problem. 2. Between 4 and 7 PSI ( up to 0,5 Bar )
Interesting question blackdevil - what would you call a normal tyre for the cbr1000rr (rr meaning race replica) ?
1. I know that you can ride a rr tyre like a street tyre, but how long will it last ? Unfortunately the streets in Britain are crap, a lot of potholes etc., at least in the area where I live. 2. I thought a Michelin Pilot Power 3 or Bridgestone S20 might be the better choice, but I will give it a second thought.
What do you guys mean by an "RR" tyre? I thought tyre choice was all about what kind of riding you do,not about what kind of bike you ride. Street legal race tyres are for being able to ride to the trackday without having to change tyres,or road racing. I also thought its all about tyre temperature,race tyres needing warmers or constant hard working to maintain grip levels,so they could never be ridden like a street tyre.
track riding only - bridgestone V01 slicks 2.1Bar front and 19.Bar rear, meassured warm after first session, cold temps are +/- F1.8 & R1.6
You are right ! Thats what are meant with "normal" Tyres and nobody mentioned the rain here. If you got sunshine, top streets and top conditions, that might be a different story, or if you constantly change form street to track with you bike.
