I put on some schwalbe g1 speed tires love these guys but they are super puncture prone.but it was night and day how these went out and did not lose air. the WTBs kept leaking. but here is the weird thing the WTBs are meant for 25mm rims and I had them on 35 mm rims and they worked great . when I put them on my 25mm new wheels then I had issues I dont know if I had humps on the 35mm rims or not.
