>>1996722>>1996721alright, I gave the wheel and tire to the clerk, he mounted a new tube. 7$ tube + 8$ for mounting it. Bought some levers, I hope I won't break those ones. I must learn the moves. He Pumped the tube to 90PSI with his floor pump with a gauge. When he gave me the tire I instantly felt the difference, the tire is super hard compared to usual.
I didn't know tubes needed a precise pressure and only a floor pump allowed to reach it. I didn't know a hand pump was only for emergency.
So yeah, I'll buy a floor pump with a gauge and check the pressure once per week.
The wheel is buckled anyway, I'll change it when I'll have some money.
Thanks to anons who advised me. (even those I didn't tag)
