Hello, the time has come and I need some tyres for my bicycle. The the current tyres say 26 x 1.9 to fit HB-575 rim.

My issue is, when I try to look for what the tyres say, it show me next to no search results and definitely nothing I could buy in Czech republic. However, when I search for 26 x 1.9 the google gives me quite a few options.Then I have no idea if it would fit my rims, though.

How do you buy tyres for bicycles? The rims are about 58cm / 22.83inch diameter. I'd say solid 23inch. Yes, I could just take the front wheel off and bring it to my local bicycle parts shop, but that wouldn't statisfy my curiosity. Also, there are some very tempting deals online.

There is a local vendor, who gives 49% OFF, on various Continental 26x1,90" tyres. I'd get some right now, if I knew they would fit my rims. Thinking

Thank you for any input,

Bike tyre sizes are a mine field.

My 27" wheels are bigger than my Friends 29" wheels and the wheels on my 26" mountain bike are smaller than my Missus 26" touring bike.

However you are talking about probably the most common size. The modern 26".

You can probably get away with anything from 1.5x2.5 on your wheel. The limiting factor on the upper size will be the fork width.

I think I have 1.9's on my mountain bike I prefer thinner tyres. I like Michelins. I have Country Trail and Country Mud tyres and change them as needed. As I recall they were under 10 a tyre.

Sheldon is useful in this, don't get confused though most of those sizes are rare and not what you are asking about. Yours will be the decimal 26", 559mm.

^^^What he said^^^

An additional factor is the ETRTO size, which is universally-applied across all wheels and is the actual diameter of the wheel rim, in mm - it is often not quoted or referenced though. If you're interested in the minefield of tyre sizes, this is a good, but lengthy read.

That said, you have a 26" wheel/tyre which is very common, so just go looking for any tyre with a 26" fitment. The second part of the number is the nominal width, in inches. Get a wider one for more volume which can offer more comfort and lower tyre pressures. Get a narrower one for more speed.

I think my 26er runs 2.1" tyres. My 29er is on 2.25 and 2.3" tyres (you don't have to match front and back - my front is a touch wider than the back).

If you are happy with what you have, get more that size.

I see, thank you lads. Thumbs Up

One more thing, do I understand this right that not all the inner tubes are equal? Meaing, I'm gonna have to use smaller inner tubes if I decide to go with narrower tyres and vice versa?

I'm quite indecisive. I'd like to try some narrow road tyres, as I do most of my miles on paved roads, but then sometimes I do some unpaved roads as well (mud/gravel).

Inner tubes are suitable over a range of sizes. You may need smaller tubes if you go quite narrow though.

To make this all much simpler, you could tell us what tyres are currently fitted. Wink

Old Thread Alert!

The last post was made 2 years, 89 days ago. Instead of replying here, would creating a new thread be more useful?
