Lostarchetict is correct.

The only other issue: make sure you get the correct valve stem. I'll add this on the chance tghat you ahve not encountered this before. Look at the valve stem on the old tube. Does it look olike the one on your car's tires, with a flat top? That is a Schrader valve. Or does it have a narrower valve stem with a little doohickie on the top that you have to unscrew (not a removeable cap, but a doohickie that extends from the middle of the stem itself and stays atached when you unscrew it as far as it will go)? That is a Presta valve.

My guess - and it is only a guess, so be sure to check - is that a Suburban is running Schrader valves. Also, a Presta valve is narrower than a Schrader valve, so a Presta valve will fit through a Schrader valve sized hole in the rim. Don't do it. Please. Trust me on this. The valve stem needs to fit snuggly in the rim's valve stem hole.

With that, you should be able to get the right tube. If you already knew all this, please accpt my apologies. But since you self-identified as new to this, I thought it better to err on the side of over-explaining - better to have and not need than to need and not have, and all that.
