What pressures do you set your tires at? - Yamaha FZ6 Forums - International FZ6 Motorcycle Community Forum

OneTrack · 09-06-2007, 08:16 PM

I have Dunlop D252's on my 06 FZ6 and have them set at the (manual) recommended tire pressures of 33 lbs front and 36 lbs rear.
I'm wondering what pressures you more experienced folks are running in your tires, particularly the Dunlops?

Once these tires are worn out, I'm installing Pirelli Diablo Corsa's, which I've heard a lot of good things about.

the stocks I used to run at 35/40
I have michelin pilot powers now. if I'm sport riding I'll run them at 30/32 , if I'm just commuting I run them at 36/42.
running the lower pressures seems to give me a little more confidence when pushing it in the twistys. if I run them at the lower psi all the time the front tire is cupped at around 2000 miles and the rear squares of after 1000 miles (this is my 2nd set of PPs I have 1800mi on these and there wearing alot better) I ran a set of Shinko 005s between the michelins, I kept the psi at 33/36 they wore well but they are a harder tire them the PPs ( more of a sport touring tire than a pure sport tire )

I'm also interested in what other riders are running. for what its worth I weigh 225lbs

I run around 36/36 on the street, 36/38 2 up, and 31/30 on the track. I currently have pilot powers and weigh about 175 without gear.

I run around 34-35 in the front and 36-38 out back.( as accurate as my gauge gets) OEM.

I'm running 35/40, weigh 230 lbs but admit I haven't experimented at all; that just seemed to be the right numbers from the manual for my weight (and the tires are gripping just fine for as far as I've dared lean it over so far!)

fz6xlr8r · 09-07-2007, 11:22 AM

I'm about 200-210lbs and with my backpack I probably go close to 230lbs so I go with the factory recommendation of 36lbs front/42lbs rear.
I wore out the 252's at about 5500 miles and never had any problems at those settings.

Since I can't deny my inner geek being a mechanical engineer and all, I assumed a linear relationship between the two points in the manual, drew the lines for front and rear, and pick pressures based on my weight and how much stuff I have with me. I then adjsut a little based on what kind of riding I'm going to do (err a little hard for slabbing, a little soft for twisties). Incidentally I end up ~35F/38-40R most of the time but I'm almost 250 lb w/o gear.
Here's the chart.

dont forget about ambient temps. all these variables is why i go by % of pressure gain from cold to hot. different tires also have different carcass thickness and flexure too, which will change the optimal pressure needed. generally i air mine up to max psi for commuting though. if im going to need good grip, ill aim for 25% gain.

Nice chart! Can you adjust the values to read from 130+ (for the smaller riders here)?

Pilot Powers, 200 lbs, 33/36.

This is what I run with twisties in mind. I need to get a tire pump for the house because I currently air-up at the local gas station. The idea of increasing psi during the weekly commutes is a kicka$$ idea! Why the heck didn't I think of that?
