BMX tire inflation

I have a temp set of BMX 20" maxxis. They suggest 85-110 psi. I normally run Marathon Supreme at 50-85 psi. Will it matter if I run the Maxxis lower at say 80 psi. I weigh 190lbs. Will it make a difference in whether the tube can handle the pressure with the Maxxis set at 90 psi?

No, it won't matter. In muddy conditions, I will deflate to about 40 psi for better traction. Be aware of pinch flats though.

Welcome to BF. This sub forum is Foo, where we tend to discuss irrelevant issues. Maybe try posting your question in the BMX MTB specific sub forum for better results. Then come back here to be silly.

Moved from Foo.

Reason why I chose here instead of the above suggested forums is because the OP has a trike of unknown design and make.

The name bentrider confirms you chose the correct forum.

First, inner tubes are not rated for pressure. The tires are what handle the pressure. Pressure recommendations are based on tire construction, size, and intended weight and use. You can always run tires at lower pressures, but running them too low will allow the tire to bottom out, which can lead to pinch flats, where the rim literally hammers a hole in the tube. This type of flat is also called a 'snakebite' because it's typically manifested as two small holes next to each other.

For road use, a tire is correctly inflated when it flattens out 10-15% on the bottom when you're on the bike. Trikes can typically run lower pressures than bikes, since each tire has less loading than on a bike.
