Tire Covers
 

My truck doesn't get driven a lot.
I use it mainly to haul my race bike to the track, and occasional commuting.
Sometimes it'll sit in the driveway for a couple of weeks at a time.
During that time it's often foggy damp, etc .. here in the fine city of San Francisco
I've noticed the aluminum rims getting gritty, and pitted.
I'm mostly worried about them just being exposed to the damp air to much.
I was thinking of getting wheel covers to keep them from being so exposed if I know I'm not going to drive it for a while.
If you try searching the internet for wheel covers you get the lamest adds for spare tire covers.
There are clearly some desperate for attention lame people out there if any of the spare tire covers I saw actually get sold.
The only thing I could readily find was RV trailer tire covers.

OK the diameter might be right but I'm thinking these just aren't going to fit my 33x12.5x16.5 tires
Anyone got any leads?
Thanks

Camping World was I was going to suggest. I did read once that you could apply a film of Vaseline on them but that sounds pretty inconvenient every couple of weeks.
