Whats the tyre pressure for front and rear tyres

Possible the recommended pressure is printed somewhere on the tires themselves but will be the maximum. The recommended tyre pressures are Front 25 psi and Rear 30 psi. The tyre pressure must not exceed 50 psi (psi = pounds per square inch).

We would advise that for your Yamaha XJR 1300 if on tyre sizes front 120/70 ?€" ZR17 58W TL (tubeless) and Rear 180/55 ?€" ZR17 73W TL the tyre pressures (set when tyres are cold) should be as follows:-

Front ?€" 36 psi (pounds per square inch)
Rear ?€" 36 psi (pounds per square inch)

you should be running 8 ply tyres on the vehicle to carry the maximum load as required by the regulator
The recommended tyre pressure will be on a decal attached to the drivers door ( probably on the door frame under the latch)
Having said all that I recommend 45 psi for the rear and 40 for the front
If you run any less ,the ride will be smoother but if you load the vehicle, the rear tyres are under inflated and prone to failure from overheating
tyres are manufactured to run at a certain pressure due to the construction of the case. Talk to a tyre shop as to the pressure you should be using for the tyres.

2002 VW Polo 1.4

Tyre: 165/70 R14
- Front tyre pressure: 2,2 ... 2,4 bar
- Rear tyre pressure: 2,0 ... 2,6 bar
- Spare tyre pressure: 4,2 bar

hi, in there wisdome kawasaki played around with tyre sizes on the zx6r ninja,

tyre size rear 160/60/17.
tyre size front 120/60/17 1995-98 models zx600f

rear. 170/60/17
front 120/60/17 1998-2000 models zx600-g1

rear 180/55/17
front 120/65/17 2000-01 models zx600j

the only thing they didnt play around with is the tyre pressures all models front 36psi or 2.5 bar
rear 41psi or 2.9 bar

hope this helps and thanks for using fixya.

NEVER the same pressure on both tyres !!
Usually, rear tyre is larger and/or carries more weight (you), therefore needs a much higher PSI. On a Hornet 250, 600 or 900cc it should be 36psi FRONT and 42psi REAR. - check the manuals.

front 1.9 bar , rear 2.0 bar w/o passenger, and 2.0 front , 2.2 rear with some fat body behind :)

Yup nice question. For any vehicle accurate tyre pressure will give you better tyre life, low running cost, etc. Here is a chart for car tyres click here.
For bikes i havent found any chart. basically in india rear tyres having 100/90 18inch maximum tyre pressure is 32psi. front tyre having 2.75P or 80/90 18 inch uses 24 psi pressure. and do check your tyre pressure twice a month.

The Cali' Special tyre pressures:- --------------- 1 RIDER.---------------------- 2 RIDERS Front ...... 2.3 Bar(33.5psi) ................... 2.3Bar(33.5psi) Rear ....... 2.5Bar(36.3psi) .................... 2.9Bar(42psi) I use BT45's on mine but I have the ordinary tubed rims. I find the ride harsh but this may be down to suspension rather than tyres. People recommend running the BT45 at a slightly higher pressure than the book. I got 8500 miles from the front and 4700 from the rear. Although the rear was changed slightly early due to a puncture. I will probably try a different make next time.
