okay, so i ride 20 x 2.4 tires that have a max psi of 110. last night my tire EXPLODED! the shop i buy my stuff from is closed for the rest of tonight and tomorrow and im going to the bmx park tomorrow. i have a old tire that is a 20 x 2.1 that has a tube in it i could use but im worried that it might be to much of a size difference and i don't what it to blow while im riding tomorrow. what do you guys think?

Should work just fine. If it's not OK you will notice a flat spot in the inflated tire, near the valve, due to the rubber being over-tight in that area. (Most tubes are built for a range of tire widths, eg 2.1 to 2.5 inches.)– Daniel R HicksCommented Apr 26, 2015 at 0:46

2You ride a 2.4 at 110 psi. That is a LOT of pressure for a big tire.– paparazzoCommented Apr 26, 2015 at 1:45

OP wrote that the tires have a max psi of 110. But hopefully he/she is not inflating them to the max pressure. That would be foolish for such a large tire.– NikCommented Apr 26, 2015 at 4:57

Unless you are particularly heavy, I would not worry about size - not that much difference in load carrying between a 2.1 and 2.4 that it will cause a blowout. Blowouts are caused by a tire failure of some description (bead failure, not seated on rim properly or cut to tire are the most common causes). You say "old tire and tube" - how old and what condition?
If your choice is ride on the 2.1 or not ride - I know what I would do.
