Road Tires: Actual Widths On LB Rims

These rims are available in rim brake or disc brake versions and are either in clincher or tubular format. Outer widths range from 25mm to 26.5mm, making them ideally suited to 21c to 28c tires (wider is possible). With a wide range of depths ranging from 25mm to 88mm, you can build up climbing, track, crit, triathlon or a mid-depth aero wheel for fondos. With a rounded profile, they are stable and easier to control in crosswinds.

Note: The above table is based on measurements taken with tires inflated to 60psi. All tires are installed with a tube. If absolutely required when mounting tires, use sturdy plastic tire levers as metal ones can damage your rim and tape.

I have a 2021 Giant Contend AR1 with Giant PR-2 disc wheels on it. I want something lighter, disc brakes, 700C that can run tubeless tyres anywhere from 28 to 38. Max weight limit of 130 kgs if possible.


LightBicycle 2021/01/30

Hi Greg, The Giant PR-2 disc wheels that you have currently is with 17.6mm inner width rim, which is close to our 17.9mm R rims. What depth do you like to have? We have from 25mm up to 55mm (10mm apart). But since you are considering running wider tires over 32c, I would recommend the 21mm internal AR rims (36mm and 46mm depth optional). Let me know your thoughts. Thanks, Lightbicycle

PR-2 disc on 2021 TCR have inner width close to 22mm, I dont remember correctly. My 28mm GP 5000 are close to 30mm on these rims.


LightBicycle 2021/07/21

Hi Petr, What was the tire pressure you run with? We only test one or two tires for each model. So the results vary from tire to tire. Thanks, Lightbicycle

I purchased Falcon AR46 wheels and I can't get Vittoria Terreno Drys on at all. Any recommendations for good gravel wheels around 35-38c that are easy to install?


LightBicycle 2021/05/20

Hi Brandon, What 700C road disc width are you using? Normally, it shouldn't be a problem for wide tires. Did you confirm that the tire beads are well seat on the center drop first before inflation? We intentionally design a deep drop so you can put the beads in easily. If you put one tire beads on the rim hook by accident, the other bead would likely not able to seat on the rim because it reaches the stretch limit. Thanks, Lightbicycle

Hi, this is really helpful. Do you have a similar chart for the newer AR rims. I’m looking at the AR36 wheel set. Thanks


LightBicycle 2021/04/23

Hi Tom, We have the AR rims listed as a tab on the right. You might miss it when you scroll down. Can you check? Let me know if anything isn't working properly. I will do my very best to help. Here is the link for AR36 700C road disc wheelset. https://www.lightbicycle.com/Disc-650B-gravel-wheels-29mm-wide-36mm-deep-tubeless-for-cyclocross-and-gravel-bikes.html Thanks, Lightbicycle

Hi - what width wheels should I get for the: S-Works Turbo, 120 TPI, folding bead, BlackBelt protection, 700x26mm? I am interested in purchasing the Falcon AR56 Disc. Thanks!


LightBicycle 2021/02/08

Hi Sir, We have got your message. Is it your bike rim brake or disc? Is it wide enough for 30mm wide? If yes, it is okay to go for our AR56 disc 700C wheelset(30mm wide). If not ,you can go for 28mm wide/56mm deep wheels. We have a picture of it. I can send the rim profile for your check if you are interested in. Thanks, Lightbicycle

Nlaw 2021/02/08

My bike is disc. Please send picture of the rim profile so i can check. Thanks!


LightBicycle 2021/02/09

Hi Nlaw, Thanks for your inquiry! Which disc rims do you like? Then i can send the rim profile accordingly for you. What is your tire width? Then we can recommend which disc rims 700C are better for you. Thanks, Lightbicycle

nlaw 2021/02/09

I am interested in the Falcon Ar56 Disc and the tires on my bike are S-Works Turbo, 120 TPI, folding bead, 700x26mm.


LightBicycle 2021/02/10

Hi Sir, S-Works Turbo is a tire, not a bike. What is your bike model? Is it a road disc 700C bike? Thanks, Lightbicycle

Hi, may I know can Schwalbe One Pro 700x23c tubeless can fit on WR38 hooked? Thanks


LightBicycle 2020/12/25

Hi Siong, 23c tires will be too narrow for the 25mm internal wide WR38 rim road disc 700C. Our recommended tire range is 28c-50c. Thanks, Lightbicycle

Warwick 2020/11/23

Hi team on the WR38 hookless can you run 60-70psi in a 28mm tire if you have a tube inside (rather than tubeless)? And any tires you'd recommend


LightBicycle 2020/11/23

Hi Warwick, We found that 28c will offer the most aero advantage if you are looking for a faster ride. But a 32c tire will make a better profile so I would recommend the 32c tire over the 28c but you can use a 28c if you would like. According to our test, you should get really good performance feedback on 49-50psi while running 28-30c tires. In your case, 35c tires should go lower, say 38psi or so. ​We have our pressure chart listed if you need some reference. https://www.lightbicycle.com/newsletter/Tubeless-Tire-Pressure-Charts.html Thanks, Lightbicycle

Have you tried the Continental GP5000 700x25c on the R65 hook? If so, how does this measure on the rim? Best, Simon


LightBicycle 2020/06/06

Hi Simon, Yes, we did test the R65 with GP 5000 25c tires. The results are the same as other 25mm wide rims on the first page. The tires are challenging because of the stiff bead. We used 2 tire levers. But it varies from different builders. We did have some customers think that GP5000 25c tires are easy to mount on. Jernej who rides our R45 (25mm wide, 45mm deep) rim runs Continental GP5000 25C without any problem. https://www.lightbicycle.com/storytelling/Jernej-Aero-Wheels-Really-Changed-My-Racing-Experience Thanks, Lightbicycle

Have you tried the Continental GP5000 700x23c on the R55 rims?


LightBicycle 2020/08/29

Hi Victor, We haven't tried Continental GP5000 700x23c on the R55 rims 700C road. But some of our customers do use 23C tires on our R series rims. It is okay. Thanks, Lightbicycle

If I'm reading this correctly, a 700 x 28 tire will balloon out past the sides of a 28mm rim. So if you wanted the maximum aerodynamic benefit while riding a 700 x 28 tire, you should put it on a 30mm rim. Is that accurate?


LightBicycle 2020/08/03

Hi Sir, Yes, the wheel width has to be slighter wider than tire width. Then it will get better aerodynamic on road wheels 700C. Thanks, Lightbicycle

Dear, I'm looking for some carbon wheels, rim brake. Height about 50-55cm. I'm happy with Novatec hubs and Sapim spokes. I'm about 94kg and I ride a Cannondale CAAD12. I ride about 10.000 a year including amateur races. What can you recommend? Furthermore I have a Canyon Speedmax 8.0, but have no disc wheel yet, do you sell disc wheels? Best regards, Hans de Boer The Netherlands 06-30342632


LightBicycle 2020/06/13

Hi Hans, Do you use 25C or 28C tires? We can check which rim brake and disc wheels 700C are better for you. Thanks, Lightbicycle
