JoeM 7,874 #1 Posted November 19, 2021 Was busting down a few old tires for the rims this week. Noticed the tires with tubes had way more rust inside under the tube. The tubeless ones with slime, by comparison, were pretty good too. Some of the tires were mates and the tubeless ones were way less pitted and rusty. Age figured 30+ years?? Anyone else seeing this? 1 1 Share this post Link to post Share on other sites
Travas 13 #2 Posted November 19, 2021 I see that a lot on tires, big or small. All it takes is a little moisture and bare metal. If the tires have sat outside, rim facing up water tends to leak through and work its magic. 3 1 Share this post Link to post Share on other sites

I believe that water and road salt creeps in around the valve stem and also that small gap where the tube can't fully conform to the tire bead. Also there is a positive pressure in a tubeless tire over 100% of the area. but not the case with a tube in the areas mentioned above. 4 1 Share this post Link to post Share on other sites
Achto 27,609 #4 Posted November 19, 2021 This is why when I'm doing a resto, I take just as much care painting the inside of a rim as I do with the outside. From the factory most rims are lucky to get some over spray on the inside, care is not really given to inside protection. 5 1 2 Share this post Link to post Share on other sites

The prints called for primer over the whole wheel and topcoat on the face and outboard flange. The corrosion resistance testing was concerned mostly with the topcoated surfaces as well. 6 Share this post Link to post Share on other sites

I have filled tubeless tires and tube type, when you have a puncture of the tube tire it is an all day ordeal to get the liquid and the tube out of the tire to patch it and now the rim is wet anyway!

echris 1,425 #10 Posted November 27, 2021 4 hours ago, Travas said: concrete instead of air How do you fill it? Chip the concrete into little pieces and funnel them through the Schrader? It reminds me of the sound my Dad's hand roller made when I was a kid. We were working on some project and the roller filled with water just wasn't cutting it. Pops needed more weight. He filled it with gravel and I will forever remember the sound of gravel rolling around in a roller/compactor for hours on end. One of these, only not new, shiny and crappy. His was old, rusty, and is probably still alive and well today at my brothers' house. lol Share this post Link to post Share on other sites

Not sure why they needed more weight in the tires for a mountain bike. Share this post Link to post Share on other sites
Peter Spirito 0 #12 Posted December 3, 2021 Approximately how much weight does adding antifreeze/water to the tires? Share this post Link to post Share on other sites
WheelHorse520H 708 #13 Posted December 3, 2021 8 hours ago, Peter Spirito said: Approximately how much weight does adding antifreeze/water to the tires? It depends on the tire size, for example I got 66 pounds by adding 4 gallons of windshield washer fluid rated for -20 degrees and 2 gallons of water (because it’s heavier). This was in the rear tires of my 520. 23x9.5-12. If you have questions about filling your tires I recommend starting a new thread to get more ideas or tricks to filling them. 1 Share this post Link to post Share on other sites
