I know there was a long thread on this recently, but...Do you follow the bike manufacturers recommended pressures or the tire manufacturers?

My bike manual lists three types of tires and pressures of 42R - 36F. However, I just had different new tires put on (by the shop) and the pressures were way lower (30-30) so

[Half Squid]

30/30 Track pressure for a 70 degree + day unless it's over 90.

Street use depends on the tire/ style riding you'll be doing.

I run 36 Front 34 Rear running Pilot Powers and I ride aggresively.

I go by the tire manufacturers recomendation if thay have one, the pressure on the side of the tire is not the recommended pressure, it's the max but it may be what they recommend,

Avon publishes recommended pressured for different bikes on their website

it there is not recommended pressure different from the bike manufacturer, I go by the bike manufacture recomendations

[Manny]

Any chance there is a listing somewhere for the pilot powers?

The bike is a triumph daytona BTW.

Michelin will ALWAYS say go by the book for street riding. Randy is correct.

For the track, start with 30F and 28R. Over 75F start raising it by 1lb at a time.

really? raise the press. the higher the temp? wouldnt it be the other way around meaning higher temps raise press more meaning LESS initial press.
in PHX i always ran the 30/28 combo because the track temp is always way up, but when i forgot to go back to 36/36 for street riding i would go through tires dratically

[smoothwaterman]

I believe that higher temps will create more heat from friction, and therefore increase the pressure even more. The idea is to have the temperature increase it a percentage of the baseline. Cooler air temps will allow a lower baseline pressure because you are relying more on friction to build the temp up. Hotter air temps will build temp anyhow, so a higher pressure will generate less heat from friction.

Karaya, Can you confirm, or am I all wet?

pb.

SWM is right - higher temps means you raise the pressure so the casing flexes less. This will put less heat into the casing.

Colder temps has you lower the pressure, so the casing flexes to put heat into the rubber to make it work.

[RandyO]

remember to adjust your pressures cold. On my SV, I set the pressures at 42R/38F with Azaro STs once the tires are warmed up, the pressure builds up to approx 46R/46F and it takes a couple hours for the tires to cool back to "cold" pressure

FWIW, I was told by Avon (via e-mail) for every 2 psi you drop from theire recomendation, expect to loose 10% tire life

in winter time, I run my Pirelli MTR60's @ 36R/33F, but when I go out riding below freezing, I drop the pressures to 30R/28F

[TheIglu]

I run my tires around 32 PSI all the time. Never had any problems running them there.

[Manny]

Is it possible that brandy new tires lose a little more pressure at the start than broken in tires?

What is a normal amount of pressure to expect to lose when not riding?

This may be a really dumb question but I feel like Im observing it in action and Im wondering if its just me or something.

[mikem317]

Running recommended pressure on the stock tires. I figure I'll find out what to do when I get them replaced.
