Thread: Question - Tyre Pressures and Temps

nah dont expect anything different pressure or temp wise unless running low pressure's

from talking to people that still have to use them....
the whole plug/tube fitting requires some care, most new punctures are caused by crap left in between the carcass and the tube..

by crap pedro means the mould release residue, bits of rubber left there from when it was molded etc, anything that is sticky or grippy will cause issues to really ensure there is no issue a little bit of telecom powder helps the tube not grip the Tyre and cause issues
Also did they put a patch over the split so the tube wont get cause in the split?

the lower the tyre pressure the more all the things listed above become more of an issue and helpful

Yep, internal patch, and I watched as they carefully cleaned it all out before adding the tube. Nice to have people you can still trust to do the job proper like!! Can't remember if they put in the telecom (spell checker again?) or talcum powder.

Assuming the small leak/hole was caused by a piece of spinifex etc and it's now patched on the inside what is the purpose of the tube ?

FWIW I really dislike tubes.
The tyre runs hotter, and in my experience I weld the tube to the tyre.
Just check the hot running pressure of the tubed tyre and adjust to match the others.
This should alleviate the tube welding issue.
Maybe.

Running to a hot pressure is a much more accurate way to manage tyres, it's how all motorsport tyres are managed from club racing all the way to F1.

As an emergency I have no issue with tubes, but long term I really don't like them.

I go to a long term, well respected local tyre place and was advised that because of the leak location, they were not allowed to plug it and kept as tubeless (presumably would be unsafe, and I've had similar advice previously from elsewhere).
I assume the patch was effectively supplementary insurance to keep the inside clean and mitigate the possibility of further entry through the hole and puncturing the tube. Under the circumstances I would logically do the same.
I didn't ask if the tyre was also plugged anyway, but good point and will now do so.


Rick 130 - I too am not a fan of tubed tyres in this day and age, but at least this way I retain my well treaded 2nd spare, and can safely run it around town and even on the local freeway (on the rear axle to minimise steering issues of course).

As others have said the tyre patch will stop the tyre defect flexing and pinching the tube.

Likewise I don't like tubed tyres, but agree with doing it to get max life out of the tyre.

I'd only fit that tyre on the back axle as tubes when punctured will rapidly deflate and could make steering interesting if on the front.
