Inner tube sizes

I've swapped out an inner tube on my hybrid for the spare that the LBS gave me when I bought the bike. But the tube that I took off the bike is 26 x 1.95, whereas the replacement that I put on is 26 x 1.2. Will this be ok or should I buy one in the 26 x 1.95 size (presumbly the same as is on the rear wheel)? Thank you.

Tubes usually have a range - do you still have the box? should tell you on the side the range of the tube example 26 x 1.25 - 1.75. A 1.2 may be a tad narrow and you could risk over filling and popping the tube.

Thanks Sky

He gave it to me in just a bag, so no box to read. I could take the tube out tomorrow and have a look to see if there's a range on the tube itself.

Does the new tube look considerably narrower than the old one, deflated?
