Hello Guys,

I own a fz-16 an year old... 15k kms done...The recommended for fz front tyre is 28psi....whenever i fill it within a day the pressure falls to 22-21 psi...

Got it checked from 3 tyre showrooms...no one could find a puncture...finally on the 4th try the guy found a tiny bend on the front rim....i could see the air leaking from the bend in the form of bubbles under the surface to water....

he hammered the rim into place and the flow of air has now curbed but still air release exists....checked the rim from the svc and the guy just checked it using his hands saying it was fine....

I m really perplexed as to whether its a rim problem and should i just replace it...or whether the tyre has run out its usage....there are abrasions on its surface....the mileage has dropped from near 40kmpl to 30-32kmpl...but more than that its a question of safety which is compromised as a result of the continuous loss of pressure...

Any help would be appreciated...
Thanks.

Did you try removing the front tyre and then submerging it in water?? The same way as the puncture guys do.

k2cool_87

yes that was done all the 3 times... as i said earlier only during the 4th try did i see the tiny air bubbles escaping from the side wall near the rim.....

This is known issue with recent FZs and R15s due to poor rim quality(Check Ownership threads for similar queries). I too faced this issue on my R15 front tyre. I got it checked at 4 Puncture repair shop but in vain. Luckily the rim was not bent and I got that checked too. At the SVC the front tyre was removed and the rim was cleaned(accumulated dirt). After that I never faced that issue.
If the Rim is bent, I guess the best option would be to get the rim replaced. FZ has tubeless tyres and the air pressure is retained due to precise shape of rim.

^^ are there any specific ways to check the rim??all the SVC guys check the rim using the hand and feeling for bumps...the tyre shop guys check it by immersing tyre in water....

i want to know if there are any machines that check the integrity of the rim of the tyre...

also i know bout frequent puncture scenario...but wanna know is 15k kms enuf reason to change the tyres??

I dont think hammering the rim back to shape is a good practice. The rims are manufactured using precise engineering. Trying to retain its shape by hammering it will only screw your handling. Try to claim warranty (unlikely to be accepted) or claim insurance on the rim

This is so not true, despite me being one the first to write about the 'issue' on the ownership threads.

The major reason for damage in RIMs is people ride the bike without adequate air pressure. Reasons for it like any owner would say
- The r15 handles like a charm even with a low pressure tyre
- The FZ tyres 'look' big with adequate air pressure

Eventually ignorance towards this important aspect leds to such a problem. Nothing to do with quality. IMO they are top notch light alloys coming as standard fitment in India.




+1 The cast alloy is like a one piece block, hammering it (even soft hammering it) can lead to cracks in the future.

Alloys are covered in Insurance, so go ahead change it ken!

but first scan for punctures... ther might be micro punctures too

I guess wat he meant was the large number of puncture cases in these 2 yamaha bikes... or atleast thats my assumption.....


will i get the complete amount for the alloys?? Just for FYI...how much is it?? and isnt it like the premium increases once u claim insurance?

^all that can be dealt around
Claim it in insurance.. I guess some 80% can be claimed. Then when your insurance expires buy a new insurance from another company... simple
