Joe Soap Posted December 7, 2018 Share I tried searching but me and this search function are not big friends. This morning I bent my front rim (FFS!) and I'm starting to shop around for replacement rims.I currently have 24mm internal width rims running 2.3/2.2 tyres and there isn't a lot of space left at the back. Has anyone done an exercise to see the rim width is effecting the tyre width?Is there a way to know for sure that if I move to a 30mm rim that there will be space?Do I do it in any case and buy narrower tyres with the wider rims (i.e. wider rims are more beneficial than wider tyres) Does anyone know of a good special on wheels somewhere?

Meezo Posted December 7, 2018 Share Run the 30mm ID rims and run a 2.25 or 2.3 tyre it a Maxxis 2.3 isn't that wide too. Then check out some of Lyne Components rims, especially the newer versions. Great support and after sales, they also offer multiple hub/axle configurations arendoog 1 Link to comment Share on other sites More sharing options...
MrJacques Posted December 7, 2018 Share Just to give you an idea of tyre widths on various rim sizes. Also remember that tyre widths aren't standardized. https://www.notubes.com/technology/wide-right https://www.pinkbike.com/news/Tech-Tuesday--Wider-Rims-Are-Better-and-Why-Tubeless-Tires-Burp-.html Edited December 7, 2018 by Jacquers Link to comment Share on other sites More sharing options...

dasilvarsa Posted December 7, 2018 Share You can use a 30mm Rim no prob.The tyre will become 1 or 2 mm wider.You can also replace the rim with one of the same size. Link to comment Share on other sites More sharing options...
Cippo Posted December 7, 2018 Share Sizing guide, hope this helps.62mm is 2.4 inches. The rim width refers to internal width. Edited December 7, 2018 by Cippo dasilvarsa 1 Link to comment Share on other sites More sharing options...
RocknRolla Posted December 7, 2018 Share Entirely depends on what tyres you are running. Not all 2.3's are created equal. A 30mm rim "wants" a wider tyres, like 2.3 and 2.4 specifically beneficial for the #enduro market. It fattens oit the contact patch, making more of the rubber available at a less of a lean angle. If your current bike has space while running 2.3's the 30's will be fine. You will be experiencing tyre rub while corenering if you currently dont have enough clearance for a 2.3 using your current rims, due to the tyre having more movement on a thinner rim.

fusion01 Posted December 8, 2018 Share Stans wide right worth looking at. 30mm rim should run a 2.5 inch tyre or wider. If you running narrower tyre then save unsprung weight and go narrower rim. https://www.notubes.com/technology/wide-right https://www.notubes.com/pub/media/wysiwyg/MTB-WideRight-Graphic-V2.jpg Really wide rims and narrower then ideal tyre combos distort tyre shapes and can make for sketchy control issues when transitioning into the hard shoulder. Inversely too rounded lacks support. 24mm on 2.25 - 2.35 is great for xc and light trail with light 450 gram 29" rims. Personally I'd keep the 24mm on the rear with a 2.25 tyre and run a 30mm rim up front with a 2.6 inch tyre (Foow mk3 etc). Fat grip on the front, fast rolling on the rear.

Me rida my bicycle Posted December 9, 2018 Share I am running 30mm with 2.25 Schwalbe and works great tyre is not squared out at all as some would have you believe. I went with the 30mm because all the narrower rims I looked at weight limit was to low. I have to say it did make quite a difference with clearance at the back but I had 20mm rims so 10mm is quite a big jump because the tyre not only get wider but taller to.

Dirt Tracker Posted December 9, 2018 Share I've been running 35mm internal rims and had to change my tyres as my standard ones started being odd when I stepped up from 25mm internal. Seemed like the profile flattened off and side knobs came into play when rolling. arendoog 1 Link to comment Share on other sites More sharing options...

Stans MK3 arch has a 26mm internal diameter .Combined with a 2,35 tyre works great and enough clearance for mud .Race face makes a 27mm internal width rim and works great also .For my 100kg ,i will reluctantly go to 30mm carbon rims on a MTB Link to comment Share on other sites More sharing options...
dasilvarsa Posted December 9, 2018 Share Too Wide Rim on Narrow Tyres actually Slows you Down.Rim and Tyre Must be Matched. Link to comment Share on other sites More sharing options...
