Tyre pressure?

[Imti]

What pressures should I be using on my VTZ250?

Thanks in advance!

Is there nothing marked on the swingarm or rims?

What tyres are you running on it?

Try 38 PSI rear, 34 PSI front for starters. You'll feel whether it's too soft and squashy or too hard and skittery, so adjust accordingly for what you find comfortable.

I find that it only takes about a single PSI front or rear before handling differences become quite noticeable.

YMMV (your mileage may vary), IANAM (I am not a mechanic), YWPCADIYLTAIS (you will probably crash and die if you listen to anything I say), etc.

Too hard Dan - try 28f and 32r

Yeah, what he said.

See what I mean about crashing and dying if you listen to anything I say?

You thought it was a joke, didn't you?

There's a rule of thumb about tyre pressures....
It says that whatever you set as the cold pressure, it needs to rise by about 10% when properly up to normal operating temperature. So set the rear (say) at 30, go for a good fang, and check the minute you stop. Tyre should now be at 33psi. If it is higher, then your cold pressure is too soft. And vice versa.

Does that mean if I set the pressure while the tyre is warm I just set it to the pressure I want?

Excuse the dumb sounding question, have been staring at hundreds of numbers for the last few hours and my brain is going to mash

If you set the pressure when the tyre is hot, it will be under recommended when cold. Obviously all makes/models of tyre are slightly different to each other, so you need to experiment a little to what feels best for you.
For a 250 of your sort, the numbers I gave earlier are about right for cold depending on the sort of tyre you have fitted. I would start there, check when hot as I said, and adjust up/down as required. Get yourself an accurate tyre gauge...the dial type are possibly best, or a digital. The pen type do not give a consistent reading unless you buy a very expensive one.

Thank you, much appreciated!

Thats what I use on my GPX.

May I suggest you invest in a digital tyre gauge?

Supercheap Auto have them at a reasonable price and they are usually much more accurate than the gauges on the "free air" pumps at service stations. And by great good fortune Supercheap are having a 25% off sale this Saturday...

This will also mean you can check your tyres at the correct temperature, ie cold.

Naaaah decent analogue gauge with a nice flexy rubber hose. Digital is for geeks.

Roger that!

EDIT: Has a handy bleeder valve too.
