Hello! Just bought a Cannondale Topstone with WTB ST i23 TCS rims (23 mm internal). I am in the market for as fast slick road tire as i can possibly put on my wheels. Is 28 mm wide tyre going to work or should i look for something wider? Thanks a lot!


LightBicycle 2020/07/10

Hi Marjan, First of all, I want to point out that our charts work the best for Light Bicycle made carbon fiber rims/wheels. Your rim is alloy rim so the rim profile design might be different from carbon rims. For a 23mm internal rim, our tire fitting range is usually between 28-48c if you plan to ride road bikes. However, I notice this is an MTB rim, The tire pressure and riding conditions will be very different. The tire should be around 2.0-2.4" tires. Thanks, Lightbicycle

Hey, im getting new wheels in my bike soon: (Ridley) VARDAR db wheels. I was thinking about matching it with 28mm tires, but im not sure if that's the way to go since 25mm might be better? Here are some stats on the wheels: Vardar DB Hub Forza 7 Beaufort db Brake Type Disc brake: 6IS Set weight 1490 g Rim Type Clincher Rim material Carbon Rim depth 45mm Internal rim width 17mm External rim width 27mm ETRTO 622-17C Recommended tire size 23-45mm Spoke count Front 24h - Rear 24h Release system TA12 F: 100mm - R: 142mm Thanks in advance! :)


LightBicycle 2020/07/02

Hi Wouter, The 28c tires should not be an issue for your wheel according to your specifications. However, some 28c tires are tricky to work with given our mounting experience, like Vittoria Rubino Pro Endurance 700x28c or Michelin Power Endurance 700x28c. Use a lever when the mounting got challenging. Thanks, Lightbicycle

26x190 is stamped on my rim which coaster tires would fit from smallest to largest thank u kindly mike


LightBicycle 2020/06/23

Hi Mike, Normally, rims manufacturers don't mark the measurement data on the rim surface. You can check with your supplier and remove the tires and measure the wheel inner width. Thanks, Lightbicycle

Hi Wii, Could you tell me the internal width of the bike rim mtb? The tire fitting is affected by the internal width and center channel design. Thanks, Lightbicycle

Hart 2020/06/14

Hello: I have an ALEXRIM DM18 rim and would like to know which tires will fit on it. Thanks.


LightBicycle 2020/06/15

Hi Hart, The internal width of the DM18 is 17.9 ≈ 18mm. It's the same with our R rims 700C road. The closest rim we got is the R25 (17.9mm internal, 25mm outer width, 25mm depth). We recommend 21~38c tires for our R25 rims. So you can take this for reference. Note that tire fitting varies from rim and tire designs. Thanks, Lightbicycle

Hi, I have a 2014 Giant Escape 1 with 622x19 rims and 700x32c tires. I use my bike on smooth and plain asphalt. I want to switch to narrower tires. Can you advise what is the narrowest tire size I can put on those rims? And what is the optimum tire size you would advise for those rims again. Thanks in advance.


LightBicycle 2020/06/08

Hi Osman, For a 19mm internal rim, we would recommend running 25c tires for the minimum. But this is only for reference because we are not sure about the rim section design of Giant. I hope this helps. Thanks, Lightbicycle

I inherited a Thruster fixed gear bike with the tire size 700x38c. I need to replace the wheels. I like the versatility of the tire size, but also like the look of the deep profile wheels (but those are more narrow). What’s the best wheel for my tire size? Is there a deep profile option for that tire size?


LightBicycle 2020/05/28

Hi Sir, Since you prefer a deeper rim, I would say our AR56 (30mm wide, 56mm deep) road rim would be a good option. Will you confirm to me if your frame spacing is enough for the 30mm rim? Thanks, Lightbicycle

James 2020/05/25

I have a 29" mtb rim with a 25mm inner rim width. I am looking at putting some fast tyres on that are slightly off road capable. If I went 700c tyres what would the biggest and smallest size, 30c - 40c? And if I went 29" tyres what would be the biggest and smallest size, 1.75"-2.25"? Eyeing up the Schwalbe G One all round 57-622 (29 x 2.25), will that fit? Many Thanks


LightBicycle 2020/05/26

Hi James, If you go with 700c road tires, the range is 28-50c. If you go with 29er tires, the range is 2.1"~2.7". Note that the tire range works best for Light Bicycle rims, you can only take it as a reference if you are mounting with rims made/designed by other manufacturers. Thanks, Lightbicycle

Anja 2020/05/19

Hi. What inner rim width would you recommend for bikepacking rim if I want ro be able to fit 27,5x2.1 tires and also 27,5x.2.8 tire. Would this maybe be possible with innercrim width of 25mm or 30mm? I am looking for the best, versatile option. Thanks for your answer. Anja


LightBicycle 2020/05/20

Hi Anja, According to our experience with tires (mount on LB rims), you should have 2 different width rim to fit with 27.5/650b*2.1" and 2.8". The range is too wide. 25mm inner width rim is a bit narrow for 2.8" tires. Thanks, Lightbicycle

Sebastien 2020/05/04

would a 2.4 work on a 35mm rim?


LightBicycle 2020/05/04

Hi Sebastien, In the Light Bicycle rim case, a 2.4inch tire would be too narrow for a 35mm internal width rim. Our recommended range is 2.5~3.1". The fitting and riding would be at the best performance. But the actual fitting depends on which tire and rim you are using. The fitting is quite complicated because of different manufacturing and design standards. It should be okay to use 2.4' tires on 35mm inner bike rims. Thanks, Lightbicycle

Hi Sir, For 23mm internal rim width, it is okay to use 2.4" if you like. But 2.3" tire will work better on this bike wheel size. Thanks, Lightbicycle

can i use 32mm width rim to 2.0 tire or 2.1


LightBicycle 2020/03/16

Hi Glong, If the 32mm width you mentioned is the internal width of the rim, then a 2.0-inch tire or a 2.1 inch tire would be too narrow to fit the rim. Our recommendation would be 2.3"~3.0". We would recommend running 2.0"/2.1" tires on rims with a 19mm~27mm internal width. But the actual fitting will depend on the tire you choose, with tube or tubeless? With rim stripe or tape? Thick tire bead or thin bead? Thanks, Lightbicycle

Glong 2020/03/26

can i fit 2.0 tires for 28mm rims


LightBicycle 2020/03/27

Hi Sir, Does the 28mm refer to the internal width of your rim? If so, a 2.0inch tire would be too narrow to fit. If it's the external width, can you possible get the internal width so I can make a recommendation accordingly? Thanks, Lightbicycle

Wayne 2020/03/06

I brought a Korean cargo bicycle home from S. Korea and when I ordered a 26" front tire as the front tire was marked on the sidewall, the replacement tire arrived but it is slightly too large in diameter. I was able to slide the replacement tire over the rim without the usual stretch. Once air entered, portions of the tire escaped the rim. Why was a 26" original tire different than the one I ordered?

I have a 29" Stout XC SL Rim, 21mm internal width with 2.1" dia tires. What would you recommend as my max tire size?


LightBicycle 2020/02/27

Hi Marc, The tire sizing chart works best for LB bike rims as rims from different manufacturers design differently. For a 21mm internal width rim, the widest tire we would recommend is 2.3". But the fitting also affected by the tire itself, some bead of tires are too thick to fit in narrow rims. The best solution is also consulting the tire manufacturer. Thanks, Lightbicycle

can a 2.3 tire fit on a Shimano MT 15 wheel? it says 559x19C on the wheel


LightBicycle 2020/02/18

Hi Sir, 2.3" tires would be too wide for the SHIMANO WH-MT15 wheels. For LB rims, we would recommend a 1.9"~2.1" tires range. But the different rim and different tire would fit differently. The size chart works best for LB products as LB rims are with a deep center channel that makes the bead easier to locate, and the small bump that prevent burp. Many details of the rim were designed to make the mounting easier and safer. Thanks, Lightbicycle

Hi Kervy, Base on our experience, a rim with a 35mm inner width should fit with 2.5~3.1" tires. 2.3" tires would be too narrow for the rim. But if you do not mind the tires width narrow, you can have a try. Thanks, Lightbicycle

Thank you for the easy to understand size guide. My question is, are the rim sizes always whole? I saw a rim with 22.4mm. Apparently its a sun ringle rebadged for niner inferno 27 rims. I am planning to get these rims (preloved) and to run it with 2.35 tires. Will it be wise to do so? Appreciate your advice on this.


LightBicycle 2019/11/25

Hi Sir, Thanks for your reaching out! For 22.4mm inner rim width, it is okay to use 2.35" tires. But if you go for slightly narrow tires, it will be better. Thanks, Lightbicycle

The 2.6inch 27.5er tires would be a little narrower to 38mm inner width rim. But you are still okay to use 2.6" if you like. It is just not work very perfectly. Thanks, Lightbicycle

LightBicycle 2019/11/04

Hi Tom, For wheels with 21mm inner/27mm outer, it should be okay to use 29*2.35 tires. But 2.0~2.2" tire with will be with better riding performance on your 29er wheelset. Thanks, Lightbicycle

I have the WTB ST i25 rims and the i25 means it has the width of 25mm. Can I put 2.5 tires on them? Base on your chart, it says yes.


LightBicycle 2020/01/17

Hi Sir, Just to be clear, the width in the chart is referred to as the internal width of the rim. The recommended tire range for a 25mm internal width rim would be 2.2"~2.6". So a 2.4" tire would be ok to mount. However, this chart works best for Light Bicycle made rims, different manufacturers design the center channel (depth, shape) differently, cannot promise this will fit for other brands's rims. I would suggest you consult WTB on this matter just to be sure. Hope the above helps. Thanks, Lightbicycle

LightBicycle 2018/07/27

Hi Kass, I think you can contact the manufacturer to get the rim profile to see the measurements for the rim. Including internal width. On the other hand, the quicker way would be you measure the internal width yourself. Attaching with one of our rim's profile for your ref so you can know what exactly should you measuring.

I would like to know is running a 2.0 trye on a 29mm internal width rim ok if I barely go off road?


LightBicycle 2018/07/26

Hi Zaw, The 2.0" tire would be too narrow for a 29mm inner width rim. The tires might come off during riding. 2.0" tires are mostly used for MTB wheels. Given the fact that you rarely riding off-road, you can consider using a road rim to achieve a better performance and safety. 29mm inner width is rather normal for a road rim. Usually, it's between 16~23mm. If you perfer wider rims, our new arrival road rim might just the one you want. You can see the rim profile from the attachment. Thanks, Lightbicycle

i would like to know what size rims [width] you need for 2.5" - 3.00" - 3.5" - 4.00" wide tyres is there a chart that gives you all the dimensions and facts


LightBicycle 2018/06/12

Hi Keith, Our tire compatibility chart is undergoing. Few recommends for your ref. 26~34mm inner width rim for 2.5" tires. 32~45mm inner width rim for 3.0" tires. 50~65mm inner width rim for 4.0" tires and 3.5" tires. Tire width is not the only factor for choosing right rims. LB can make a proper customized recommendation for you. It will fit your profile better. Is this ok with you? If you like, pls provide below info so I can recommend accordingly. 1. What kind of riding you do? 2. Your weight 3. Your frame or fork 4. Aggressive riding or not? Thanks, Lightbicycle

Purchased the 29 AM rims & built on existing hubs. Noticeable stiffness and smoother ride compared to Arch EX rims. Tires are definitely more voluminous with this rim. No way a tire is coming off these rims with the hookless bead and the diameter of the rim. Tires (Maxxis 2.4) go on easy but once filled with air, they pop in place. Only compliant is a tire is tough to break the away from the rim once the tire is filled with air, but once you break the bead into the middle rim channel, the tires comes off easily. Great rim so far but only have a 300-400 miles on them. I weigh 165 lbs. and run 22/25 psi on 2.4/2.25 tires(front/rear) on full suspension bike.

Hello Mark, Thanks for your support. We are so happy you are enjoying your new rims. It would be great to see a picture of them on your bike! The center channel design is for mounting tire and taking off tire. The channel is deeper, while you mount tire, the tire has to be seated on the channel first. After pumping the air, the air pressure will put the tire go to the bead seat area. If you like to take off the tire, you have to take the air out first. Then remove the tire to the center channel first, it will be easier to take off. It is tubeless design. Happy riding! Light-bicycle
