Some important RV tire do’s and don’ts

Courtesy Dicor Corporation
In our previous tire reports (see below), we discussed some of the key things to look for when taking your RV out of storage. Here are some important tire do’s and don’ts.

Do the following

DO check your tires’ current inflation levels. Tires can lose up to two pounds of air pressure a month just sitting around. Unless you’ve compensated with more inflation when you put your unit in storage, the tires are likely a bit underinflated now.

DO drive your RV around a bit to even out flat spots. After some months of sitting unmoved in the same spot, and possibly with a load of “stuff” still inside, your tires will likely develop “flat spots” where they have been pressing into whatever surface they’re on. So when you first take your RV out of storage for a drive you may find your ride a little bumpy for the first dozen miles or so, until the rolling heat evens them out. But don’t keep driving if you keep feeling the bumps. If you continue to experience a bumpy ride after 12-15 miles, you might want a service center to check your tires in case there is a serious problem. I always say, better safe than sorry.

DO clean your tires with soap and water. I’m sure one thing you’ll be doing to prepare for RVing season is cleaning the exterior; including making those tires look brand-new. The safest and cheapest way to clean your tires is with mild soap and water. Stay away from the hard stuff!.

DO find out how old your tires are. To determine the age of your tires, one good thing is that your tires will always tell you exactly how old they are, unlike some of my friends. Your tire’s birthday is stamped right on the sidewall. Look for the last group of four numbers after the “DOT” mark embossed on the side of the tire. The first two numbers in this cluster indicate the week in the year in which the tire was manufactured, with that year noted by the second pair of numbers. So, say the last four numbers are 2910. That means the tire was “born” in the 29th week of 2010. And yes, if you’re buying a used RV, always ask about the tires’ DOB.

Don’t do the following

DON’T use petroleum-based cleaners or special dressings on your tires (the hard stuff). You could be making your tires vulnerable to damage from ozone and UV rays if you are using petroleum- or alcohol-based cleaning agents, silicone oils or tire dressings, all of which can dissolve the same protective tire coatings used to block ozone and UV rays. So your good-intentioned cleaning can be causing more harm than good!

I hope you follow these tire do’s and don’ts for your safety, your family’s safety, and the safety of everyone around you. Safe travels!

Clean the tires?
I wait for the rain to do that.

Two topics which draw out the Rv “experts” on social media; tires and tow ratings. My own Rv tires have rolled just about 25K miles but will hit the ten year mark late Summer. Will be hard to replace considering the tread is still good.

Always ask to see the tires before they are installed. I waited for new tires to show up for my pick-up. When stocked on the shelf, the tire date was “2020.” This was March,2021, Clerk was amazed that I knew their age. Called tire guy to double check. He agreed. Did not buy them.

I don’t think one year old tires are an issue, especially with Rusty above saying HIS tires are 10 years old. Remember, you’re new tires will be one year old in, well, one year.

Depends on what brand of Rusty’s tires are. Some brands are more susceptible to rot than others. My 7 year old Michelins were showing considerable dry rot on the side walls. I replaced them yesterday and made sure the Michelins that were installed were made within the last 6 months. DOT on my new tires: 0421. I’m a happy camper. They will probably outlast me.

I just got off the phone with a tire dealer and they have five 2021 and one 2020 – I’ll take them!
Seems to be a bit of a tire shortage (could not get Continantals), so I will snap these Michelin up. They will replace the perfectly good looking 2009 tires with less than 20k miles on them. :-/
