Can I use this tire + rim combination : CONTINENTAL GRAND PRIX 5000 (28mm) + GT540 (24mm) I have the rim **DT Swiss G 540** , which inner width is **24mm**. I already bought the CONTINENTAL GRAND PRIX 5000 tires **28mm** (saw this advice on reddit). But now I checked the official table and see that they do not fit together very well... :( **Rim:** ![enter image description here]( **Acceptable tires:** ![enter image description here]( The tire width is only 2mm less! What do you think - can I use it or better not? On my last trip the tire came off the rim - but not sure if the tire size is the reason or I just overinflated it by CO2 cartridge: ![enter image description here](

Its clearly not-recommended by the rim manufacturer.

On top of that, the tyre has come off for you proves that its a bad combination.

That it is only 2mm is immaterial - it came off and could have severe consequences.

There is no glue or strap or ziptie or bodge-fix that will allow you to use this tyre and rim combination safely.

Your options are to buy a wider tyre, or replace the rim with something narrower. A 32 or 34mm tyre would be cheaper than a new rim, presuming the rest of your frame provides clearance for a wider tyre.

If your front rim is the same inner width, the same advice applies. If your front rim is narrower, then it _might_ work with this tyre.
