Did they give me the wrong tube?
 

I just ordered a 110/100-18 tire and a 110/100-18 tube

The problem is that tube is stamped as 130/90-18, 5.10-18, 4.5-18 and not 110/100-18 as stated on the dealer sticker.

Do I have the right tube for my tire or should I return it?

Thank you

There's very little real world difference in most tubes over a fairly wide range of sizing as long as the wheel size is adhered to...at least as it applies to the size ranges you're dealing with here. A lot of tire/tube sizing claims and advertising are often somewhat voodoo-like. With the exception of wheel size, you can see some really different size comparisons even though the tires and/or tubes are marked the same. Don't worry about that tube. It'll work fine with your 110/100.

Thank you!

I was worrying because last time the dealer gave me a Michelin UHD 18" type B, which was a 130/80-18, to put in my previous 4.6-18 tire.

It resulted in a flat caused by the tube who folded on itself and tore up at the end.

I just don't want to waste more money while risking another flat.

Yeah, the UHD style tubes are a little more critical as per installation in a smaller tire, but I contend they'll still work if you're very careful during the installation. Powdering up the tube and then airing up and airing down at least once before doing the final air-up and tire bead seating will insure you don't get a troublesome fold in the tube.
