If pneumatic tires are stored at 60°C (140°F) or higher (e.g. in a car in hot weather), deflate the inner tube to 1 bar/15 PSI to avoid valve deformation. Especially when riding on high temperature black asphalt pavement with temperature exceeding 65°C (150°F), the tire pressure may easily exceed the allowable maximum value. In addition, too high tire pressure can cause the tire to break away from the rim during cycling, which can result in the risk of injury. If you inflate the tires in a cool garage in the morning (18°C / 65°F) and ride later at higher ambient temperatures (35°C / 95°F), it may result in an increase in inner tube pressure (e.g. 0.5 bar/8 PSI). Every 3° (5°F) increase in temperature would increase the tire pressure by about 1%. Tire inflation pressure must not exceed 5 bar/72PSI When using rims with a no-ring-lip system according to ISO/TC 31.
Before inflating the RideNow tube, turn the valve inward (towards the center of the tire circle). Inflate a small amount until the inner tube is round; this pressure should be less than 0.5 bar/8 PSI. Please use a manual air pump instead of high-speed air filling equipment such as air compressors or pumps. This inner tube cannot be inflated a lot when it is not installed in the outer tire, otherwise it will cause irreversible damage!

Лучше бы я купил ZTTO. Камеры не получается накачать, это очень тяжело. В нипеле клапан уходит слишком глубоко и затыкает отверстие для накачки и застревает, приходится его выкручивать. Камеры очень тонкие, когда бортируешь колесо монтажками, почти всегда её протыкаешь, потому что она всегда вылезает наружу

отличные камеры. легкие и никаких проблем с ними не было.

Buen producto, trae dos parches en caso de pinchado.

обе камеры спускают, в накаченом сосотянни при проверке в мыльном растворе обноруженно множество мелких отверстий

I have not used these MTB tubes before but if they are as good as the 700c tubes there should be no problems.
