Tyre (tire) pressures for Metzeler Z6s?

Post by **MartinW** » Fri Mar 09, 2007 11:01 am

Any advice on pressures for these tyres - with one 160lb rider and speeds up to 90mph approx (on the Autobahn of course!)

My handbook gives a generic 32 front 36.? rear but I notice that oilhead.com's CheatSheet shows 38/40.

no idea what the weights mean cos I still work in stone - but I run 36/42 which I believe is the Tyre manufacturers recommended pressures.

RIDE mag tyre guide states 2.5bar front 2.9 bar rear which in real money is 36/42 psi for R1150R 01 - with 5.5" rear rim

36/42 sounds good to me.

(I was catering for the American market quoting my weight in pounds!!)

Thanks to both for the info.

A stone is approximately 14 pounds?

A stone is exactly 14 pounds. Just a quaint little measurement that we use on this side of the pond and after all 11st 6lbs sounds much lighter than 160lbs!

I weigh a lot of stones.

I learned about stones when in Scotland. I dont want to consider my total in stones!

I think I am going to quote my age in Stones..... $\:D/$

That took me a minute! Can stones be used as a unit of measure for any ole thing? Sweet!

Yeah, why not? My age would be 3 stone 7, then! Sounds way better than 50 something!

I weigh 160 lbs. Secondwind BMW set the pressure at 38 front 40 rear when they installed my z6s.

Those pressures seem pretty high.
My bike wears out the centre tread fast enough already!

I'm 15 stones and use 36psi front and 38psi rear , which is the recommended BMW two up pressure.
I know some tyre manufacturers seem to recommend a universal higher pressure.

I've been running 38/42 on my Z6s at the recommendation of my dealer. I'm a slim 275lbs (2 3/4 boulders--not stones).

I've got what I think is an amazing 10k on the rear and it still looks good.

Metzlers wear like iron and are worth every cent.

I seem to have graduated from stones to rocks in the past few years. I'm now getting back down to stones! Rocks are too heavy to carry around.

16 ounces in a pound - 14 pounds in a stone.

2.2 pounds in a kilogram.

Then there is the US measure and the imperial measure to add more confusion. A US gallon is a different quantity to an imperial gallon!

And - 36/42 for me, loaded, unloaded, fast, slow, pillion, pillionless.

I pump up my tires to 36 psi front, 40 back. I check pressure periodically until each tire loses about 4 psi and add air.

Those Florida roads must be awfully smooooooooth to get 10K on a rear Z6

I got 14k out of my last rear Z6 up and down the East Coast.

oddly enough - having a LOW pressure will allow the tyre to deform more, and make it heat up - thus causing undue wear.

so having the pressure lower is going to square the tyre off quicker....
