SILVER Star
IS IT?
the way shown allows you to fill the spare up with air WITHOUT dropping it onto the ground! that little yellow "low pressure" lamp gets pretty annoying after a while.
So does one of these
And the cosmetic side of the wheel isn’t exposed to damage from road use or when you drop the spare on the ground.
Also the anchor on the chain that actually lifts the wheel isn’t designed to fit into the lug side face. I’d bet damage is being done there too.
Lastly, you can fill your spare to the limit listed on the tire to buy more time before it crosses the threshold of needing filled. If you need to install it, just lower the pressure to whatever you run on the road before driving away.
