Let me set the scene:

Location: LBS
Time: A few hours ago
Situation: Picking up some rims, tires and what the hell, some tubes.

Okay, so I pick up my recently trued Rims, finally, and needed some new tread. So I pick up the Cont. V. Pros. Have-em on the other set.

The sales guy, says, do you need some tubes. I'm like, yeah. Just ran out. So he brings me a size tube that fits 26 x 1.5-1.9. The tire is 26 x 2.1.

Im like, wtf, so I say, I need it to fit a 2.1.
he's all, naw, this is what you want.
I'm like no, dude, the tire is 2.1, the tube only fits up to a 1.9.
He starts going off about how the tube will expand to fit the 2.1. Im like expand, what ever. It is going to flat after I hit the first drop.
So I say, I got some 1.9's at home, so no need to "Waste my money." :evil:

So, is the sales guy right. Should you run a smaller tube size than a tire size or should the tube size be the same size as the tire.

Thanks

And is it a huge no-no to put in a tube that's slightly larger than the tire size? I just put a size 2.4 (I think) size tube in a 2.35 tire.

1.9 tube in a 2.1 tire is no big deal. If the tire were like 2.4-6 then you might start to have problems.

I hear that, but would it be better to run a size that includes the 2.1 size?

I mean they had a tube that fit 1.9-2.35?

Rock on

Do you mean Conti Vertical Pros? They are 2.3 not 2.1.

Yeah but they size up more like "normal" 2.1s.

Tires and their goofy different sizes vs. what they claim to be!

I'm running some Tioga Factory DH 2.1s tonight on my Balfa and these suckers are wider than the Kenda Kinetics 2.35s they are replacing. Hopefully they will work well tonight too....they have a pretty meaty tread design, yet I think they'll roll faster than the stick e rubber kinetics.

As tire and tube dimension vary so much from manufacturer to manufacturer (2.3 Conti is more like a 2.1) I would say those 1.9 tubes should be ok.

Yeah there has been 2 in the lounge today, it's a miracle!

My spare tubes are 1.9 and when I need to, I have run them in 2.65 without issue. I carry the 1.9 tubes as spares because they are cheap. I tend to swap them back when I get a better tube.

But now that I think about it, I think there is one in there now... Oh well, so far, so good.

I guess you're right. It's probably that "endless edge" that makes them appear to be wider.

Tubes come in sizes?

For a 2.1 tire, those would fit just fine. For a 2.3? Probably work fine also.
