Question 1

How do I know what size tire cover to buy?

Accepted Answer

Measure your tire's overall diameter across the face and match it to the cover's size. The Camco covers here come in fits for 24-inch and 34-inch tires, and getting the size right matters: a cover that's too big flaps and lets sun in at the edges, and one too small won't stay on. Measure directly rather than guessing from the wheel size.

Question 2

Do tire covers really extend tire life?

Accepted Answer

Yes, for a rig that sits. RV tires usually fail from UV cracking and age rather than tread wear, and blocking the sun during storage slows that breakdown. Covering the tires won't stop aging entirely, but it noticeably extends the usable life of tires that would otherwise crack in the sun over a few seasons.

Question 3

Should I cover tires even if the RV is only parked a few weeks?

Accepted Answer

For short stops it matters less, but there is no harm in it, and if the rig sits in strong sun even a few weeks of exposure adds up over the years. The real payoff is on rigs stored for months or parked outdoors year-round, where UV exposure is constant. If your rig sits more than it rolls, covers are worth keeping on.

Question 4

Can old RV tires be dangerous even with good tread?

Accepted Answer

Yes. Tread depth tells you nothing about age, and a tire with plenty of tread can have dry-rotted, cracked sidewalls that blow out on a hot highway. Most makers suggest replacing RV tires by age, commonly around six to ten years, regardless of tread. Inspect the sidewalls for cracking and check the date code, not just the tread.

Question 5

What is a valve stem extender for?

Accepted Answer

On dual wheels or inner tires that are hard to reach, an extender brings the valve stem out to where you can actually get a gauge or air chuck on it. Brass extenders like the Wheel Masters unit here make routine pressure checks possible without crawling behind the wheel. It is a small add-on that makes staying on top of tire pressure far less of a chore.
