I tucked away a couple of small 1 3/4" car tire patches in my underseat bag. They can be glued in with regular bike patch glue and cut down to size if needed, however I think a whole one will fit in my 28mm tires. They might need to be trimmed to go in a 25. I'm sure you could find a box of them at any auto parts store or ask at your local tire shop, they might sell you a couple.
