As a base reference, 29psi front and 35psi rear. Rear depends if you usually have a passenger or not, the 35 value is only driver, with passenger up it in 2-3 psi.

My front are 2.1 psi and the rear is 4 bar

Does this affect mpg if rear is so high?

If it were little pressure yes, with more pressure no. But, if the pressure is excessive, you are going to wear the rear tire a lot in the center. With the front wheels the difference is not much, except for the grip in the curves.

What is most important in the MP3s is that both front wheels have the same value.

Thanks for info.

So what is optimal as manual says
2bar front and 2.4bar rear

does it matter if front is 2.1-2.3bar…..everyone has different ranges? For me it's just single rider no pillion.

Hoping my mpg might improve as today I got 45mpg on 60mile commute to London and motorway……being summer expecting better figures but not seeing yet.

There should also be a sticker or plate that states the tire pressures, somewhere on the MP3.
On my 2008, it's right in front of my right shin. Nerd emoticon

that's the maximum with passenger - not the recommended for driver only

Apparently my rear tyre was a Bridgestone and my local garage said to change to michelin brand that is common on MP3s and match's the front tyres. So just don't that….psi on rear is 2.4 bar let's see how this goes….

Matching tyre models front and back on a motorcycle is NOT important. They do completely different jobs. As long as the tread is sound, you're fine.

Looks a little flat down the center line, possibly due to all the straight line highway driving you've been doing. But otherwise it looks like it has plenty of tread depth and life remaining.

Have you rotated the tire to check for thin or bald spots? The suspension on the Mp3 is not great and the rear tire can bounce around allot on rough roads causing damage and uneven wear.

You'd best buy a tire-depth gauge of your own which will help with such decisions.

I believe uk limit is 1mm for motorcycles I recall in cbt training.

The guy mentioned similar down middle is low but by no means I'd have thought it's illegal or an MoT failure.

You prob right about the wheel bouncing around esp on odd bumps as I norm dodge with front wheels and then feel a bump on the rear wheel that goes over a pot hole etc.

I have the business version does the sport 500 have better suspension? Is it worth upgrading?

The stock Mp3 shocks are generally rubbish. Fine for around town, but not so great for touring or routinely going over rough roads.

But it depends on which stock shocks are installed. The defaults on my 2016 were actually causing the rear tire to wear down faster than normal due to all the loss of traction, bouncing around, etc. I put in a set of Malossi shocks and my rear tire is now lasting much longer while the bike is more steady on the road.

This is whats installed on my 2016, but I don't know if it fits your model.

Check the tyre wear indicators - raised bits in the tread. If they're flush with the surface the tyre is worn out. You can find where they are as there are "TWI" markings around the edge of the sidewalls.

Pretty safe to say that you were taken for a ride.

Unless you see the wear bars the tire shown in the pic still has lots of life left.
