>>1486777>the current one is tubelessi highly, highly doubt that. Take them off, i bet there are tubes in there. Tyre selection is important btw, that's where your ride quality comes from. most hybrid tyres are pretty garbage
i suggest maxxis DTH 2.1 folding with skinwalls
measure your clearance to make sure you have room but you should
upgrading to thumbies is a great idea. lurk for some used 7 speed XT ones in co-ops or used shops or online or whatever.
basically you should re-cable the entire bike and clean and regrease the hub and headset bearings. It's a good project.
I would also upgrade the brake pads to kool stop, and the pedals to some nylon bmx pinned flats, and the saddle, and buy some meme bars, and get some oury grips. and set it up with a rack and metal basket and remove the kickstand and remove the reflectors and buy a nice chain and maybe a new cassette and maybe a new bottom bracket.
