I finally got new tires after almost 1500km on my Kenda tires that came with the bike. I searched for months but never really found any 24x4 tires. I even considered getting new wheels. The only tires I found that looked reliable and decent were CST BFT. I was worried about how small the knobs looked but I went through with it anyway. Kenda is 30tpi vs CST 60tpi. The results are... Kenda is very soft and plush. Bigger ballooning out the sides. Contact patch is much bigger. So the tires look noticably bigger. Rubber is soft. Works well down to 5 psi. I like mine at 13psi. Lots of flats from any tiny little thorn until I put a liner and liquid. Decently sized knobs that go up the sides beyond the contact patch. Now for the CST... CST feels like harder rubber. Not as plush ride. Feeling bumps more but having more traction. Less slipping. Less lag on acceleration because less power lost to the plushness. Minutely faster and stronger uphill. I actually like it a lot. Very different feeling than the super plush Kenda tires. CST performs very well on road. And also off road. Very happy with the performance it's like a small upgrade. I also like the very slightly smaller profile. I have them on with liner and liquid. Joe's flats. If anyone knows any other 24x4 tires that seems reliable please let me know.
