Protecting Tires from House Cats I have a friend with several cats, one of which destroyed the material of their bike tires and is presumed to enjoy doing so.. having acquired new tires and tubes (but not yet put them on), how can we prevent the cat from chewing/scratching the new pair?
We had thought

bag the tires (no good; likely too thin and they love bags too)
move the bike outside (no, it will definitely be stolen)
spray the tires with lime juice, vinegar, etc. which the cat will find unpleasant (this at least works for ferrets which love chewing cables)
decoy tires (see: cats on keyboards)
some sort of removable, thick rubber coating (perhaps a second, larger pair of tires cut to fit over mounting)
hard case for bike (probably too expensive)

Other details

bike is a Schwinn road bike without fenders
no garage is available and it is impractical to store at my place
the cats are otherwise delightful
bike will be left unattended indoors for long periods of time (weekends/workday..)
open to trading in the bike and getting something heftier if that's the only solution

Likely also suitable for Pets StackExchange, but I doubt this is an unheard-of problem in this community
Have you thought about a bike cover or bicycle wheel covers ?
This seems the most logical form of protection for little outlay, the most effective method would be to move the bike out of reach of the cats but if that’s not possible then a cover of some sort may suffice.

If the cover isn’t suitable or the cats destroy it, you could easily make a bike stand from some 6mm mdf, make it wide enough to stand the bike in but tall enough to cover the wheels
If I was on a PC i would draw up a quick image / diagram of a simple stand.
If you have hydraulic brakes do not stand your bike upside down.
