2016 CT tire tube problems

Woe unto you that bought the first model year of a major remake, perhaps this section can help address any 2014 and later model Ural "imperfections". Here's a special section for folks with the latest rigs to discuss 2014 and later model-related topics such fuel injection, 3-wheel disc brakes, hydraulic steering dampers, spin-on oil filters and other anomalies that don't belong on true Russsian motorcycle ;-P We've gone from using big hammers and greasy wrenches to needing computers and Ouija boards in order to fix our rigs.
Forum rules
Please keep this section specific to issues pertaining to 2014 and later models such as fuel injection, sidecar and rear disc brakes and so forth. Ask general or non-2014 and later specific questions in the main Hammerin' & Wrenchin' section.

2016 CT tire tube problems

Post by MotorMan » Sat Dec 15, 2018 12:58 am

All three of the tires on my new 2016 CT required air every couple of days. When it was about a year old, the rear tire left the rim on a gradual right turn at about 30 mph. Both the bike and I survived the controlled crash. A few months later, the front tire started going flat over night. I had the tube replaced although, when out of the bike, the tube stayed inflated at a few psi. A month later, the sidecar tire started going flat over night. With it still on the bike, I found slow leakage around the base of the stem. My conclusion is that in the original tubes the attachment of the stems was faulty. I would not trust a tire with the original tubes or replacements from the same source.

I top off my tubes about once a week. Still running one of the originals on the 09.

my 2016 GU check every 2 weeks only maybe 1 -2 pounds all around. think i would put in a full set of premium HD tubes and double check the rim band or replace. with good tubes and installation done correct, you will be good to go. :cheers:

I fill up my tubes once a week. They are the German ones that came on my bike with the Heidenau tires.

Depending on how fast my rides are, I can loose up to 5psi a week.

My 2015 cT needs air in the front and sidecar tires weekly (2-5 psi drop). But Ural New England Installed a new rear Heidenau and a new tube of higher quality and I see a drop of maybe 2psi over 3 weeks or more. I hadn't checked it for several months this fall (shamefully not ridden) and the rear tire was down about 5 psi vs 10 psi of the front and sidecar. So, it's a tube thing.

The Olympic Peninsula and western Washington got hit pretty hard by snow this past week. The stock Heidenaus do not cut it at all in heavy snow. Two years ago with fresh snow about 4" deep it did well. But 12" of packed snow and ice? Hahahahahaha

Looking to replace all the tires with knobbies as I want to do more fire roads and trails. I'll replace the remaining tubes at that time.

What/which Heidenaus are you calling "stock"? They make a lot of different types.
I run the K37's and they are excellent in snow, mud, etc.
But... you will give up a bit of comfort on the street/highway just like you would with a dual-sport bike running knobbies vs. trials or mixed-use tires.

Also, 12 inches of snow brings the surface close if not right into the bottom of your hack. Tires can't help if the rig is running higher than the snow.
Watch smoking you clutch. I found out the hard way.

Is a CT one-wheel drive or two-wheel drive? I forgot. If "one" you only need a knobby on your pusher. Not snowing all year round.

Yep normal for me. Only weekly? :? ..? I need to check my front every 3 - 4 days, certainly not leave it longer. Pusher is around weekly. Note both tubes are replacements as spoke nipples holed the oriiginals. :(

The sidecar tube is factory original and still holds air. Altho I do check it often.

Yep happened to me too, as I said, the spoke nipples damaged two (different) tubes, so the damage is on the inside, rim side, not the outer tire side. Still waiting for the sidecar inner tube to pack up! :o

Try double rim strips.

Mine had double rim strips, they seemed to have caused the problem by pinching and/or the edge rubbing thru the tube. Dealer had extra wide 30mm strips which he prefers to put in. Got those, OK so far. Image

Probably the K28 which was OE on my M70. They don't do well in snow, about what one would expect with all weather tires on a car.
