I have just bought xjr 1300 2009 what r the tyre pressures

I also have a keeway super light 125 and the tire pressure is 33 PSI in the front and back.

worn tyres have nothing to do with the sensor, the sensor is for pressure only.
tyres are not covered by manufacture warranty.

hi, the presures recomended for a yamaha xjr 1200, 1995-1998running tyre sizes

front 130/70/17 presure is 2.5 bar =36psi with or without a pilion
rear 170/60/17 presure is 2.5 bar =36psi solo and 2.9bar 42psi with a pilion

hope this helps, and thanks for using Fixya,

Have a search for an owners forum, they should be able to help. The other way is to look at what make of tyres you have, then go and look on the manufactures website. Avon tyres, for example, will let you select the bike you own, then give details of their recommended tyres and their recommended pressures.
hope this helps.

I think that your tyres are faulty as the volcanisation of the tyre is uneven. It will be good to show your tyre to the manufacturere or if the bike is new to the dealer for a replacement.
Once the tyre has bulged then it is softened on this section as it is uneven and can be dangeorus.
You can use within the bulge area an inner casing but this will make the tyre unbalance and the riding will be diffficult. So dont attempt this method.
So please check this out and hope my advice helps. Good day

Usually if you look closely, it is written on the tyre side wall. But just in case it isn't, try 34psi for the rear, and about 32psi for the front. You can give or take a few PSI, if you want a softer ride down to 30psi.

check on the sidewall, should be like 42 psi max. have local tire store fill them up and ask what pressure they put. it will probably be manufacturers suggested pressure.

all passenger cars run at 32psi front and rear. unless low profile mags and tyres are fitted the run around 36 psi. hope i have helped.

According to my Haynes manual for 600 and 1200 Bandit fours the correct pressues are 33psi front and 36 psi rear

Sayin that it says the 1200 is 36psi front and rear and everyone kens it's 36 and 42
