Do you know those were pneumatic tires? My guess for late 1800s Australia would be solid rubber, given that Dunlop started commercially producing pneumatic bike tires in Ireland in 1890, IIRC. > — My rear wheel plan is a cliffhanger, which has an inner width of 25mm. > Will this work with a 38mm tire, or be too wide? > Probably too wide. Here's a Mavic engineering article on tire/rim width: http://engineerstalk.mavic.com/en/the-right-tyre-width-on-the-right-rim-width/ I agree with Daniel that pinch flats are going to be a problem with a load and narrower tires. I don't know that tubeless would help with tires at that width. You can pinch a tubeless on a rock and have it burp out the sealant. Also, it's not just total weight but distribution of the weight. With all the load over the rear tire, it's going to take more of a beating than if the load was distributed more evenly across the bike. Might as well try it but take extra tubes and a patch repair kit. jim m walnut creek, ca -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
