Can I use the same exact tire set up on 20mm rims? Theyre Bontrager connection wheels Thanks!

LightBicycle 2021/04/14

Hi MJ, Our tire fitting chart works ok for most of the carbon rims on the market. But given the fact that the design of rim bed and bead hook are vary from manufacturers, the installation will be lightly different. 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

Hey guys, I’ve got an older frame and the wheels are marked 559x21c and the current tyre is 26 x 1.90 The metric and imperial cross over is getting me confused. So the internal rim width is 21mm, it’s a 26” rim and the current tyre is 1.9” wide, is that right? I’m trying to find the narrowest tyre I can fit to this rim to use the bike for more hybrid/gravel settings rather than MTB! Thanks in advance

LightBicycle 2021/03/02

Hi Sam, Our tire size chart is regarding our own rims and only for a reference, the narrowest tires for a 21mm inner width rim is 1.9 inch. If you want to make sure, you could contact your rim supplier to make sure the narrowest tires that you could go for. Thanks, Lightbicycle

Hi - struggling to get a correct answer so hope you can help. I bought a bike with DT Swiss 485D rims, currently with 700x42 tires. Would you know what the narrowest tire that I could use on these rims? Would be interested in x35 or x38. Thanks so much.

LightBicycle 2021/02/26

Hi Jim, What is your current road disc rim inner width? Thanks, Lightbicycle

I have a wheel set size 26x50mm what size tires could I put on it? This for a Cruiser bike. Thanks for any help

LightBicycle 2021/02/19

Hi Richard, What does the 50mm refer to? The external or internal width of the rim? The internal width is measured with the tire removed. The tire fitting depends on the internal width (ref to the chart) and rim bead design. Thanks, Lightbicycle

I have a wheel that is 50mm internal rim width. Will a 4.6 inch tire fit this wheel? Thanks.

LightBicycle 2021/01/27

Hi Sir, Are the 50mm rims fat bike rims? or just a plus rim? Thanks, Lightbicycle

Hi, my gravel 650B internal rim is 24.5mm, can I run 2.2" tire on it? Thanks.

LightBicycle 2021/01/23

Hi Kevin, Yes, you can use 2.2" tires on an internal width 24.5mm rim 27.5er. But the compatibility varies from design and manufacturers. Thanks, Lightbicycle

Will the maxxis minion DHF 2.3 tyres and maxxis minion DHR II fit on a Cube aim pro 2018 mtb 27.5" diameter and 20mm internal rim width?

LightBicycle 2021/01/19

Hi Sir, The Maxxis Minion DHF 2.3inch tires will be a bit wider for a 20mm inner rim 650B. Our recommendation is 1.9~2.2". Thanks, Lightbicycle

Hi Light Bicycle, I have the Continental GP 5000 in 25mm. Can it fit in the WR50 rim?

LightBicycle 2020/12/17

Hi Jackie, Yes, the GP5000 25c tires will be very easy to mount on WR50 rims gravel. We tested with the tube inside, and it was very easy to install, no lever used. The center channel room is more than enough for the tire beads for you to put them into. Thanks, Lightbicycle

Is 2.30 maxxis minion fits on a 33 mm internal width rim?

LightBicycle 2020/12/11

Hi Felix, Yes, a 2.3" tire can fit for a 33mm internal width rim. But it might be a bit narrow for some rims. Depends on the rim design itself. So, it would be best if you can reach out to the manufacturer to be sure. Thanks, Lightbicycle

I have a bontrager race x lite rim that is 30mm deep, I need to know the inner rim diameter for what hub I get, I have the 280mm long spokes but I just need to make sure I have the right length spoke for the hub I get

LightBicycle 2020/11/27

Hi Keaghan, Hi Keaghan, Do you know the rim model that you have in hand? We will need the ERD and internal width. Also, if you can provide the hub measurements (from the manufacturer or hub model number). We can calculate the spoke length for you. Have a nice day! Lightbicycle

Can I run a 2.4 on a 40mm rim trek roscoe

LightBicycle 2020/11/10

Hi Mark, A 2.4" tire would be a bit narrow for a 40mm internal width bicycle rim carbon. I would suggest going up to 2.8". Thanks, Lightbicycle

How about a tire 2.1 in a 30.6 inner width rim? ( 27.5 MTB)

LightBicycle 2020/11/04

Hi Nan, 2.1" would be a bit narrow for a rim with 30.3mm according to our experience. We wouldn't recommend it. But also depends on the rim and tire you have. Which 27.5 er bike rim do you have on hands? Thanks, Lightbicycle
