Tire preasure

[Fire_Eyes]

Hi, I have a 1998 zzr400 and have BT-014's fitted on them. 120 on the front and 160 on the back. The problem is I don't know how much preasure are they supposed to have. I went to a fuel station and the lad there checked the preasure, 30 on both. He reckoned that's about right, and when I ride it feels about right. What do you guys/gals think? I weigh 80killos if that helps. Thank you for your time.

Shouldn't it say on the side of the tyre?

No Somerset, it never has on any of the tyres I have had!

Haynes manual?

Try the pressures for a ZZR600 maybe...

Or have you tried the tyre manufacturers website?

Failing that try 32 front and 36 rear. Thats the default pressures on a surprising number of bikes!

HTH.

Remember kids, bikes aren't like lego. You can't easily take a part from one bike and then fit it to another.

Thanks Marjay, but I forgot to tell you one thing... I live in the Middle East . In the summer it gets to above 50C and in the winter it doesn't get under 10C. So what I'm saying is the average temprature for around all year is around 30 degrees centergrade .

My tyre pressures are on a sticker on the swinging arm, 29PSI front and rear for my CB250.

I would say for a ZZR400, 30 front, 36 rear, if the front is a bit unstable drop to 28psi.

Best advice is to get a decent pressure guage, guages at garages are not always
calibrated properly. I still use the same pressure guage that came with my GT550,
it's just a basic "pen" guage.

[Fire_Eyes]

I think I will just increase the rear tire to 32 and see what difference that makes.

My tyre pressures are under the seat, on a small tag there. Maybe worth checking yours, see if there's somewhere on the bike that lists 'em.

Need to take a look at my pressures tomorrow actually, I did a post on here the other day about my bike feeling funny. Gonna go out and get myself a digital pressure guage and a nice shiny new pump.

remeber when you do check the tyre pressure, to check your pressures when the tyres are cold, ie in the morring before you ride it.

The tyre manufacturers website usually gives a more accurate psi for the bike and tyre combo.

[Jrod]

I did my pressures the other day, was a few psi off, it makes such a difference when they are right!

[Fire_Eyes]

Cheers everyone! I'll make sure to check them in the morning. I went to the Bridgestone site but couldn't find anything except the max psi. Anyway I don't care, today the bike is gonna be done from all the repair and black apintjob , new rear tire, black buibble screen, and if you read the post about the burn out going wrong... a new clutch .

Hi.

Since I bought my scooter in mid August this year I haven't once checked my tyre pressure because I don't how to. I haven't noticed any difference in the handling. Do you need to buy a special tool that reads the pressure off or something?

Thanks Dan.

[EuropeanNC30R...]

You need to buy a tyre pressure gauge. They're quite common, and can be had for 5 quid or less. Try Halfords. Once you got one, you remove the valve cap on your wheel, place the pressure gauge on the valve then press on it for a couple seconds. It should then display a reading.

Alternatively you could use the free air pump at a garage, they have gauges on them. However they're not very reliable.

[Dan 4RR]

Thanks for that reply maurice. Looks like I'm going to have to buy one of those pressure gauges.
