how hard is yours?

ok what i mean is how hard do you pump your tubes up?
I realise that the temperature plays a big part but how solid should they be?
I don't think the valves on my rib (delta) are release ones So is it possible to burst the tubes if say i pumped them up in the evening and the next day was hot and sunny?
any advice/experiances will be useful.

I always keep mine pretty hard. I get a better ride in the rough with them hard as they don't move around so much. Damage, if you stuff the boat for example, is less likely too.

You have to watch them in the summer. I always let a little air out if the boats going to be sitting on the trailer in the sun or I know temperatures are going to rise. When on the water its much less of a problem as the water/wind keeps the tubes temperature down.

well I have a different opinion and wonder how many out there agree. The tubes should not be too hard as they must absorb the impact of the ride. The harder the tubes the harder the ride. I check my tubes by just pressing my fist into them obviously they can't be too soft so you just have to get a feel of it. The tube must act like a shock absorber .

Tried both, and concluded hard is best. I like a 2 inch diamater depresion when pressing hard with my thumb, if that makes sense
