You crazy Brits and your "Metric" system! LOL

Those pressure are about right, if they are "PSI."

I run 28f and 36r psi, on my 82 XJ650J. But, I go about 14.6 stone.

 

Here is the thing about tires.. all of them will differ. You need to find out from the manufacture what the proper tire pressure is. Do not go by the owners manual if you don't use the original tires. Like my bike I am currently using Metzler 880's and they run 41 psi in the rear and 38 in the front. Ten pounds more than what the owners manual will tell you. You need to call the manufacture and they will tell you the correct psi for your tires.

 

Most tire manufacturers have a website with that info available. Some refer you to the manufacturer's recommendations; most new high-tech tires have their own set of specs.

In my case, my Avons also require a higher pressure than stock; but not as high as OBD's Metzelers. That info was on their site.

 

Interesting!

I was always under the impression, that we are to use the tire pressure recommended by the manufacturer of the bike.

I always thought the pressure on the tire is the max pressure, under which the tire manufacturer guarantees that the tire won't explode.

So, I should be following the tire max pressure and not the what the bike sticker tells me?

I may have to readjust and see how the ponies perform!

You learn something new every day...

 

There was s a difference between the max pressure on the tires and the recommend running pressure. Running at max can quickly wear your tires and cause some handling issues since it will shrink your contact patch.

 

You do not want to run max pressure this is simply a number that you should never go above. If you contact the manufacture you will find out what pressure you should use for your specific tire.

 

thats opened my eyes on tyres, did not know tyres are manufacture specific on pressures, looks like the tyres on my xj700 are the same from new 29 years old look ok and passed yearly mot test last week but must confess at 53 years old now only out on bike when its dry and above 15 degrees

 

OK. BUT... these are tubeless tires. Anything over about 6 years old is dangerous; unless you want to crack them off the rims, change the valve stems, and fit tubes.

Otherwise, don't ride any faster than you want to be going to deal with a blowout.
