I know this must have been done before, but for past 8 months I have been riding my ZZR I never checked the tyre pressures... naughty i know.

Well i wasnt sure what they should be etc etc

Yesterday when I was at cycletreads...

(that ramp is dangerous to newbies... i almost dropped it three times going up it and down!! hate it! what a stupid idea :sick: )

...i asked them what they should be... but i forgot :( i think he said 34/38 ??

well i get to the petrol station and tap in 34 on the dial to do the front... 28 psi.. yikes.. and then the rear... 19 psi FLIP! no wonder it was feeling weird :gob: ...how dangerous is too low a pressure??? was i asking for death at 19psi?

Disco Dan, what size tyres are you running on ? It definitely can't be 34/38 ZXR 250's which have 110 in front and 140 rear run on 34/36.

I think your's would be 110 front and 130 rear in that case it's 30/32. But check it out on manufacturers sites?

The way that I understand it is that if they are too flat.... you will run wide on corners.... well thats what I have been told...... and when that happens to me off I go and get some air back in them.... especialy if I too havent checked the tyres for a little while.... its one of those wee maintainence things we must do and check on our bikes as well as many other things.



(thanks always to Kerry at Motohaus for pumping them up for me)

19psi is not a bad pressure, for gravel.

How could you nearly drop a bike on Cycletreads' ramp? At the bottom you squirt, then brake. At the top, just roll down. how hard can it be ?

Well i followed kittyhawk there and had never known about the place. She went zooming throough the doorway and up the ramp... i thought 'cool a ramp' ...went zooming up after her and just about filled my pants when i saw a line of bikes parked up in front of me at the top... just had enough time to turn and skid to a stop.. missing kitthawks bike by about an inch... was at this strange angle and holding weight of bike on my foot at about 45 degrees... she grabbed the bars and pulled me up! :innocent:

going down? well how the smeg did i know someone else was coming UP the ramp?

Dont like that place :( will avoid it!! dont like that ramp!!

You might also be running on wrong profile tyres on that ZZR, and you wonder why you can get up that ramp!

Lol..do some research mate, from memory I think you have to be on 110 in front and 130 at back!

But I could be wrong? Anyone with a ZZR out there or GPX, think they take the same tyres?

zzr250 tire size (gpx as 16" rims i think from my bad memory not 17")
Front Tyre Size 3.00 x 17” (3" wide rim, 17" tall)/ 100/80 17” (100 wide, 80 tall, 17" rim)
Rear Tyre Size 4.00 x 17” (4" wide rim, 17" tall)/ 140/70 17” (140 wide, 70 tall, 17" rim)

Personally when i was running my zzr250 i was using 130 rears, made it turn in heaps quicker.

Best tires i had were bt45s i think it was(going back about 6 years ago now)
