Ironman Mountain Bike Huffy

How do I determine the tire size of my mountain bike tires?

I have a Huffy “Ironman Triathlon Pro” 21 speed mountain bike that I got a few years ago. My back tire is pretty worn and I need to replace it.

I went online to browse bike tires and there are so many sizes and variations, can someone please tell me how to figure out what size tire I need? Is it as simple as measuring the wheel that it’s on?

Thank you!

First number is wheel diameter ie 26″; 2nd number is width is 1.9 =1.9″ wide…
Get a 26 x 1.9 you will like it. I would guess you can go as wide as 2.1 with that Huffy.
Heres one on sale for $5
