Nightmare!
Fitted front tyre (Schwalbe Marathon Plus 32c) and although it turned with mudguard on the clearance was minimal. Could hear rubbing noise every revolution!
Then, couldn't even get the back one in. In the end had to remove both mudguards to fit the 32c.
Aaaggghhh!!!!
However, just completed 52 mile charity cycle in terrible conditions and it's not a deal breaker having mudguards. Probably won't be putting it back on at the moment.
Although, given the number of bolts etc, probably couldn't!
