Piss poor online fitment guides

You should try riding a 1000cc sportsbike with the recomended 42psi in the rear tyre. All its good for is for drawing 190 wide black lines everywhere.

I Cringe when i hear people asking what pressure to run.

Should know that all modern radials in common sizes should be at say around 36psi - then the variation +/- comes in: Depends on the tyre, type of riding, type of load (are you a fat fecker) etc..

then chuck in personal preference as how you like it to feel.

Well said!!

I ran front 36 and Rear 0 a couple of times and the amount of grip is phenomenal; although the tyre wear is a lot quicker than normal.

On my Street Trupple R the recommended pressures are 36F and 42R, but I am fairly light so I run 32 or 34F and 38 or 40R. depending on how hot the day is.

I havent run it on a trackday yet but I anticipate that would be something like 30F 28R to start with then measure the hot temps after I finish a session.

By the way I always do them before I leave on a ride, with tyres cold (or as cold as they will get that day) and I use a hopefully accurate gauge called an Accu-Gauge. I dont own a compressor I use my bicycle track pump if I need to add air. 10pumps is about 1psi up.

There has been a general "agreement" among tyre manufacturers in place for a while now to standardise pressures at 36/42. I suspect that this may be more about being part of protecting their arses in certain countries than about agreed performance parameters.
I have PR3's on my Speed Four and I started with the pressures in the handbook at 34/38 initially and then played with them up and down from there. In the end I settled on Triumph's pressures or 33/36 depending on the season. Good performance and comfort (36/42 was a bit hard on the kidneys on some of our bumpier roads) and on average for the PR2's and PR3"s about 15,000kms to 17,000kms (yes I'm a Nana rider....)

I run 42psi cold in the rear when i am doing a 600 to 1000k rideday, its is worth a few ks at the end of the tyre life, having said that the honda can leave black marks anyway, but is made up by the front tyre being lifted of the road. Manufacturers recommended pressures are most likely for the OEM spec tyres anyway, not the real McCoy.

I don't see how a tyre manufacturer could recommend a tyre pressure. That's controlled more by the weight, load and expected application being placed onto the tyre - which only the bike manufacturer could know.

The only thing they normally put on the sidewall is a maximum pressure for the maximum load

Agree with the first bit, however I would say its something only the rider could know, but that both the bike and tyre manufacturer could guess at. Don't really see what the big deal is about some not providing that info, I think Hitcher should just be happy that some manufacturers do take the time to provide that information, and I doubt it would take much to find another bike on the list with similar power and weight to get a ballpark figure from anyway. Next thing you know he'll be complaining that they don't do the actual tyre fitting online too

I run mine at 32 front and rear. Will get (if I haven't already) 10,000km+ out of the sport demons on there now. Probably don't check them as often as I should, so I shall now consider myself reminded.

Don't feel special Hitch, I had the same drama when I first tried to get info from Mr Michelin when I started fitting Michelin rubber to my current toy. They basically said to stick with the bike manufacturers' recommended pressures.

Here's what I found for my GSX750F fitted with Michelin Pilot Road 3. Suzuki says 33psi front and 36 psi rear. Not a bad place to start but I found the front feeling on the soft side. Onto my second set of PR3s and I've worked out +2 for the front and +1 for the rear gives good wear and handling, wet or dry. BUT, I doubt your wife weighs as much as me....so it's down to personal choice, which is what you knew anyway me thinks?

[TOTO]

36/40 is what we put. you are bang on the money.

[Hitcher]

which only the bike manufacturer could know.

And given that OEM rubber isn't generally available off the shelf, then fat lot of use that information is.
