Tire Size Chart For Bicycle Rims

Tire Size Chart For Bicycle Rim

When it is time to replace your well-worn tires, it is a good opportunity to unlock the full potential of your wheels by trying something new. This chart will provide guidance on what tires sizes can match your internal rim width.

Unfit tire size could damage the rim and put the riders in danger. If the tire is not wide enough, you’re risking more pinch flats and blowouts; if it is too wide, tire burping and poor stability may occur.

In this blog, we list the recommended tire size charts for LB mountain/road/fat rims. Check it carefully before ordering carbon rims or buying new tires. If your combination is not listed here, please contact us to discuss it.

Note:

The recommendations are based on our rim-tire compatibility tests with some of the most popular tires. This chart only serves as a general guide since bead design, inflation pressures, and other variables will affect the actual rim-tire compatibility. Please send the rim profile to the tire manufacturer to double-check.

We don’t suggest choosing the largest or smallest values of a size range. For example, with a range from 1.9” to 2.1”, 2.0” is an optimal option for most riders.

The chart is only applicable to Light Bicycle rims with a unique rim-tire interface. If you use rims of other brands, please send a rim profile to the tire maker for recommendations.

I have a KHS Alite 1000 mtb with 559x17C rim, with internal rim width mentioned as 17C. & ETRTO Recommended Tire Section Width as 25mm-52mm. So in this case I can replace my tires with upto what width?


LightBicycle 2021/07/07

Hi Rohan, The fact that we don't have 17mm internal alloy rims. our recommendations might not be properly. I suggest you contact the rim maker Weinmann. Thanks, Lightbicycle

LightBicycle 2021/07/28

Hi Shena, Is it your current 29er wheels with 23mm inner width? If yes, it should be okay to fit 2.3" or 2.4" tires. You can double check your supplier. Thanks, Lightbicycle

Will a 27.5" X2.0 fit a 27" road rim


LightBicycle 2021/08/02

Hi Wayne, 27.5" tires are with bigger BSD, so they might a bit bigger for 27" rims. So the tire beads might not fit well with the rim bead seats. You can check with your wheel 650B supplier. Thanks, Lightbicycle

Hi lightbicycle, im just wondering can i use a 2.25 maxxis tire on a 29-30ish mm rims? Or rather can i run them safely mostly pavement and light trails..


LightBicycle 2021/06/22

Hi Marvin, 2.25" tires should be ok to mount on a 30mm internal width rim 29er rim bike. But if the 30mm means the external width, please remove the tire to measure the internal width to find the best-fit tire range. Thanks, Lightbicycle

Hi Can maxxis aggressor 27.5 x 2.3 put to the wheel set etrto 584-21


LightBicycle 2021/06/11

Hi Nulz, Yes, you can use the 21mm 27.5er rim with a 2.3" tire. But it might be a bit wide. You should check with the rim manufacturer to be sure. Also, please make sure the frame clearance is enough. Thanks, Lightbicycle

My bike currently has -Specialized Espoir Sport Reflect, 60TPI, wire bead, Double BlackBelt protection, 700x30c tires. I'd like to put new tires on for gravel riding. What is the biggest size I could get?


LightBicycle 2021/05/25

Hi Judy, What's the rim width your wheel has? What frameset do you have? Or what's the clearance? What would be the terrain that you plan to ride on? The more rough the gravel gets, the bigger tire you need to run with. Thanks, Lightbicycle

Hi Light Bicycle its a compatible my 23MM WIDTH internal rim on 26 x 2.125? and what maximum tire my 23mm width internal rim?


LightBicycle 2021/05/21

Hi Melvin, A bike carbon rim with 23mm internal width should have not a problem install a 2.125" tire. We recommend running tires under 2.3". But if you want to know the precise maximum size, you should contact the rim manufacturer considering rim design varies from factories. Thanks, Lightbicycle

Hi Can I run 28c on the WR45 32 wide rims? I am buying a wheel that I want to cross between gravel and fast road riding. Thanks Dan


LightBicycle 2021/05/14

Hi Dan, Yes, most 28c tires on the market are ok to mount on WR45-25mm/32mm rim 700C gravel. You can check out the tire measurements that we tested. https://www.lightbicycle.com/newsletter/Road-Bike-Tire-Width-Charts.html Thanks, Lightbicycle

Hi, I am currently using in my gravel a 28c, can i switch it with a 40c tire? is it possible theoretically?


LightBicycle 2021/05/12

Hi Sir, I would need to know the internal width of your grave wheel rim to know if they are ok for a wider tire. Typically, gravel rims are with a wider profile that allows wider tires gravel. Thanks, Lightbicycle

I have Giant MTB wheel size 29er (internal width rims 25mm). and I want to change narrow tire (now tire 2.25) by using Gravel bike tire 40mm. is it possible ?


LightBicycle 2021/05/10

Hi Ricky, The 40mm tires would be too narrow for a 25mm internal width MTB rim. What riding are you plan to do? Thanks, Lightbicycle

Hello, I’m currently running 2.10s front and rear my rim says 559x 29 what tire sizes are compatible with this rim size ? Thank you


LightBicycle 2021/03/15

Hi Ronny, Can you tell me the model of the wheel or rim 700C you have? The marking and standard are a bit different depending on the factory. The rim center design is the key factor to a good tire fitting. Thanks, Lightbicycle

Planning to build a 700x40c wheelset, that's the max tire clearance of my frame. What rim width can you recommend? My frame is a Polygon Bend R5 gravel bike


LightBicycle 2021/03/11

Hi Yaniboi, Thanks for your inquiry! May i know your current tire width? Are you going to use 40C tires? And my i know your weight? Do you ride aggressively? Then we can check which gravelwheels 700C are better for you. Thanks, Lightbicycle
