Tire Pressures

[TOMCAT]

I've always run 45 rear 40 front on ME880's .. been told I will get better mileage out of the tyres a tad over- inflated .. seems to work. Hunty you reckon just a couple of PSI was noticeable in regards to handling ?

The tyre guy who fitted new front and rear Metz to my Roadster recommended the same as pressure Tomcat is using.

Yep she felt lighter on turn in and when changing direction (almost describe it as flickable ha ha ha ha)

Sorry to get back on topic...tyre fitter at the race track i was at recently suggested 37/38 front (Avon Cobra) and 36 rear (Bridgy Ex) for the best handling...I was at 40 and 40/42...He was right...

as you were gentlemen...

Was that recommendation for the racetrack, where you'd obviously be pushing your tires hard, or for everyday riding?

I've tried such lower pressures for my normal riding (fairly aggressive, lots of twisties and graded roads - moderate amount of stop & go) and the bike felt somewhat squirrelly (less stable), especially in hard turns.. running hard on a less inflated tire also seems to accelerate the further loss of pressure in the tires.

Also, your report of "lighter" or easier turn-in with lower pressures seems counter-intuitive as the lower pressure creates greater rolling resistance (friction) and increases sidewall flex which should serve to diminish lateral stability???

live on dirt rds, use roadster to cross country it to the swimming holes, chase cattle etc, ride highway 1 to work (still a f#cking goat track) lower pressures suck for me, 40/42 feels comfy & peels rocks out every angle

sure you could pump up the tires to 50 psi and get more gas mileage what concerns me is the front tire and how fast i can stop. i run 36 psi and at that pressure it has a fair contact to the road if you pump it up to 40 psi it will have less contact and might make a small difference in stopping distance. imho

I can assure you, even at 43 psi front 45 psi rear, the big girl still stops just fine. Is it longer that lower pressure? No idea, but it isnt overly easy to activate ABS on either brake without deliberatley trying to on the front or being lazy and just standing on the rear brake.

@mr hunt the tyre guy was more than likely allowing for pressure build up after a few laps, did you check them hot after a run?

back in my sports bike days we would drop our tyres a couple of psi for track days cos the heat build up on track where the tyres don't really get to cool down between corners and the lower pressure actually enhances grip by causing extra heat to build up in the first place, but I wouldn't do it for road I run 40psi in front and 42-45 psi depending on whether I am towing while running a bike tyre or 28-30psi with DS tyre
