>>1612542>replace the tires on pic related?before you begin have a look at the rear wheel hub
if its an internal gear hub there will be some like of lever or chain protruding from the side where the chain is sprocketed, this must be kept indexed
some of them have a window or notch to view the index, in some the cable can be detached, others not so much
see
https://www.parktool.com/blog/repair-help/internal-gear-hubsaxle bolts are mostly 15 mm, yours may be different, I can see that there are some anti rotation washers on the rear axle, note how they are installed, so you can put them back later
to get the rear wheel off you will have to remove the hub brake torque arm on the non drive side, flat blade screw driver and a 10 mm wrench should work
the front wheel appears to be a dynamo hub, some have an electrical plug on the right side that can be undone
those tires look like 26x1.5 but I would be wrong about that, check the side wall for numbers
here is an link to a PDF showing common tire sizes
https://www.cateye.com/data/resources/Tire_size_chart_ENG_151106.pdf.eg 26 x 1.5 is listed as ETRTO 40-559
https://en.wikipedia.org/wiki/European_Tyre_and_Rim_Technical_OrganisationETRTO is a little more consistent for tire sizes than the inch system
inch tire sizes are not consistent
