I'm just in the process of doing the first tyre change on my YZ, and was pleased to notice that it already had Heavy Duty tubes fitted. As I haven't yet been 'blessed' with a puncture whilst using HD tubes in my bikes, I was wondering if moving to Ultra Heavy Duty (UHD) tubes was likely to give any real benefit? What do folks here use, and what (if anything) has copped a puncture for you? Do UHD tubes really make you puncture-proof?  |

Hi pete ,
Running pirelli's on the rear these days and really like them alot , problem is they have a very soft wall and if i hit something unexpected like a stray rock or a small log at speed they can puncture relativley easily so I use UHD all the way mate front and rear , UHD also gives me the option to tighten up the rim locks a little more and run a lower than normal pressure for a bit more bite in general if i choose .
Go the UHD if you puncture one then the HD tube would not have stoof a chance .

It dont matter what you ride as long as you ride often .

Thanks Zeb
Guess I'm trying to work out if it is worth the extra cost, weight, and harder fitting seeing as I already have the HD ones...
The new tyres are MX51's so they have pretty solid sidewalls.

UHD tubes for me as well, we never had them back in the day,& I never had many punctures that I can remember, I always try to avoid things like rocks sticking out,square edged holes running into small tree branches across the track, now I use UHD tubes I still pick my lines, I hate having to fix flats out on the trail, come to think of it, I hate working on the bike on the trail full stop, I go out to ride, not out there fixing my bike  Using UHD tubes doesn't mean that you wont get a flat tyre, the chances are a lot less of getting one if ya use em |
Falling off doesn't hurt, it's the sudden stop that does the damage.

Im the same as frankie, I go out to ride not fix my bike. |

Thanks for the feedback guys - and yes Frankie, I totally agree that the line you ride has a lot to do with whether you will get a puncture or pinch flat. I'm not keen on the idea of swapping tubes on the trail either, but I haven't had to do so for the past 2500km+ with just the HD ones. Maybe I've just been lucky.  Will, 4 years without a puncture sounds like a pretty good recommendation for the UHD ones! Anyway, I'll suss out what sort of UHD ones are available - from what I've read so far, it appears that Bridgestone or Michelin are the brands to look for. |

UHD when we ride but carry HD in the back pack as they are a lot lighter to carry...AMX should have UHD for as little as $25..
Cheers...

Interesting bit of trivia - the whole reason for taking the tyres off the YZ now (apart from fitting new boots to the YZ) was to fit the front one to the 'old banger' WR in preparation for the ride in a couple of weeks. The old Trelleborg front tyre (mid 90's era) on the WR is rubbish compared to even the semi-worn newer style front tyre from the YZ, so I figured that I would swap it. When I got the tube out of the WR, I noticed that it was noticeably heavier and thicker than the Maxxis HD tube from the YZ, and still looked almost new. Looking at the brand on the tube I saw that its called a Michelin Speciale cross/enduro, and according to Google it is a fore-runner to the Michelin UHD tubes. Well, at least I did something right back in the old days |

Michelins are 4.5mm thick, not sure about the rest. |

From what I've read so far, Bridgestones are 4mm, and Vee-Rubber are to be avoided |

Interesting - Is it only the synthetic rubber ones that do it, or do the Bridgestone & Michelins do it too? |
