Parking a bike with wide tyres in a narrow bike rack I park my bike at work in a rack like this:



At the moment I have 26 x 1.9" knobbly tyres and the wheel just squeaks into the rack. However I'd like to replace these with 26 x 2" Schwalbe Marathons for a smoother ride and better puncture resistance, and these almost certainly won't fit.

What's the best way of putting my bike in this rack if the tyres won't fit, preferably without annoying colleagues by taking up more than one space? So far I've thought of:


using the lock cable to 'tie' the wheel to the side of the rack - possible but a bit of a faff
fitting the bike with a kick stand so it doesn't need the rack to hold it upright - not ideal
getting the 26 x 1.75" tyres instead - would work but I'd prefer the wider ones for best grip as my ride is partly on offroad paths and a cobbled street (and nothing to do with thinking the wider ones look better, honest).


But are there any other techniques or products I haven't thought of?

(Security of this type of rack is not a big concern, incidentally, as the rack is inside a shed with a code lock.)
The solution in my particular case turns out to be that the 2" Marathons are actually no wider than the 1.9" knobblies - when fitted on my wheels and at my current inflation pressure of about 3 bar, at least - so the bike still fits in the rack. 

This won't help anyone whose tyres actually are too wide to fit in a narrow bike rack, but it may help someone in a similar position to know that tyres may be slightly narrower than their nominal width.

In a year of riding on the Marathons, incidentally, I've had one puncture, compared to about one a month on the standard tyres. I also found the difference in rolling resistance compared to knobbly tyres was surprisingly noticeable.
