Very well explained, even better than many other videos presented by native speakers of English here on KZbin. Thank you so much👍

[@pikola24]

Thank you very much for sharing your knowledge. You do a great job with these videos!

[@laurentneu7354]

Very useful/clear video thanks 👍

[@dtbrooks7325]

Thanks for the lucid and thorough treatment of a topic that is not explained frequently. I particularly needed to see the charts of minimum and maximum tire size for the given internal bead width.

[@DannerPlace]

Good video, thanks for posting.

Im only 12 years old and im trying to figure out if i put 20 x 1.75 tire on my 20 x 2.40 rim will fit... Im getting confused about it because its the same diameter and im planning to buy the 20 x 1.75 tire but now i know that it won't fit im trying hard to find same size of the rim but i dont find any

[@BikeGremlinUS]

Hi, See the tyre sizing standards article linked in the video’s description. It explains the sizing, and which tyre widths range can fit which rim width. Relja

[@B_COOPER]

That frame bag strapped to catch the handlebar swing is brilliant.

[@randyholloway920]

He didn’t include 20” diameter wheels.

[@BikeGremlinUS]

See the link in the description. I couldn't fit all the sizes on the screen without making it way too small, but it's on my website. Relja

Can I put 16 x 2.40 tires on 16 x 3 rims

[@BikeGremlinUS]

This article should answer that question (what to measure, how, etc): bike.bikegremlin.com/285/bicycle-tyre-dimensions/ Relja

My mtb tyre is 29"* 2.1 ... I got 29" *2.35 tube.. Is it fine to use?

[@BikeGremlinUS]

Hi Wani, I believe this article answers your question (what to messure, tight spots to look out for and similar): bike.bikegremlin.com/285/bicycle-tyre-dimensions/

[@robt6695]

Great explanation very well put together. Especially as its not your native language. Good job mate.

[@ricklieffering241]

Thank you very much for this info. I've been searching for someone to come up with a clear answer and your chart was all I needed. Thanks helps me pick a really good fitting tyre for my bike.

[@nancybryson5488]

This was one great video. Info I've been looking for but so hard to find. Thank you so much!

[@themouas]

Thank you for the video I finally understand tire sizes.

[@mcalpine007]

Thanks, helped a lot.

[@r.williams8349]

Thank you, great video.

[@BikeGremlinUS]

Thanks - glad you like it. :) I couldn't find a cameraman for recording, so wasn't sure if it would all be clearly visible and explained.

[@r.williams8349]

@@BikeGremlinUS It was very clear :)

[@emilch8341]

I need new rear rim for my Trekking Bike (Focus Marakas), my original rim dimensions are 662-19C and I have ordered 662-21 . It's only little bit wider. Will the rim fit on my bike? Tire dimensions are 700x40C.

[@BikeGremlinUS]

If there's not a lot of room (less than a few mm), then it's always a test-and-see if replacing a rim for a wider one. If there's plenty of room, then no worries. Details on the tyre sizing, and tyre & wheel fit are given in this article: bike.bikegremlin.com/285/bicycle-tyre-dimensions/

[@mudithmanu]

Well explained. Thanks.

[@luisord93]

Talking about road performance tires...do you know by any chance what's a recommended tyre pressure for 23mm tires mounted on 25mm rims?

[@BikeGremlinUS]

Hi Luis, Here is my article about the optimal tyre pressure - with a rough ballpark pressure chart: bike.bikegremlin.com/799/pressure-i-inflate-bicycle-tyres/

[@rramirez3555]

Excellent! thanks!!

[@kristofermed1f]

on some sharts tey say i can put a 23 size wheel on a 17 mm rim=? but you write minimum is 25? can i still use 23?

[@BikeGremlinUS]

My chart is "conservative," i.e. it's what works with every tyre and rim combination I've seen. Going "one step" over or under in rim size, compared to what's recommended in the chart works fine most of the time, with some common sense (for example, make sure your tyre is not underinflated if you are going with a wider rim).

[@FlorinCalisthenics]

Hello i can put smart sam 2.6 on my 23mm internal rims

[@BikeGremlinUS]

Hi, It is on the wide side for that rim, but I would expect it to work fine. P.S. I wrote an article with tyre and rim width table charts: bike.bikegremlin.com/285/bicycle-tyre-dimensions/ Relja Novovic

[@13richjenn]

Thanks!!

[@benoitarteau2078]

Wow my back rim is 13.5mm and my front is 15mm.

[@BikeGremlinUS]

It happens. :) On a more serious note: rims needn’t be identical.

[@diceymaan]

Great content and really informative! Bought a classic bike and twice got the wrong tire, before I learned 26 is not always 26". 😄

[@FagunerDin]

Well explained. And the best thing is you are describing in a way of sharing experiences including all aspects of consideration.
