I have G670's coming up on 7 years this October. Still look great and hoping for a couple more years. I've never covered my tires, only kept them rolling with right amount of air pressure.

Did you keep your tires covered and does it really make a difference?

I do keep them covered when staying 1 week or longer at any place.
Use Pressure Pro to keep track of pressure.
I run 5-10 PSI above Good Year chart for my weight.
Outside temps will make the 5-10 PSI difference where I usually travel.

RV usage of tires is the worst because we do not use the tires enough to keep the emoluments active which keeps the rubber in good shape. Commercial use of tires is virtually constant which is why commercial tires are replaced from tread being gone and why the carcasses can be recapped.

Keeping sunlight off of tires can help but ozone is everywhere and ozone works on tires as much as sunlight.

My experience was a perfect looking (no checks) 7 year old tag axle tire disintegrated causing a lot of body damage. When the spare, that had never seen the light of day, was dropped to be used, you could see that it was in no shape to be, externally.

I don't mess around with tires. I recently aged out the trailer tires at 6 years. They look perfect. Same for the truck. At $440/$410 each, it was a major contribution to the economy.

Being cheap on tires, either in buying or running them longer, is a bet you life action.

- At the beginning, work with a tire dealer that will take the time to obtain 6 months or younger tires. (Not always easy to do, especially based upon the brand you choose. And sometimes tires shortages, as in the 2015 under estimation by Michelin on tire demand, can impact this too.)
- Four corner weight. Set tires to your actual weights per the tire manufactures weight charts. Add minimum of 5psi contingency, or 10%, whichever you feel works for you.)
- Spend the money for tire pressure and temperature monitors. (Calibrate these based upon our actual per tire PSI readings form a reliable gauge. Many of these sensors can be + or - up to 5 psi of actual ratings, usually more like + or - 3 psi)
- At the start of each day, before taking off. Check you tire monitor for current PSI's. Consider if one side is baking in the sun, and outside temperatures. (You get a feel for this.), when looking at these numbers.
- Daily walk around of rig, should include visual inspection of tires, including taking a knee and looking in as best you can at the inside dual. Look for sings of damage, bulges, cracking. (No, you will not see everything, but you can at least look at what you can see.)
- Come up with your replacement timeframe schedule, and budget accordingly. I'm on a 5 1/2 - 6 1/2 replacement schedule. And do this based upon the oldest tires Born on Date (Date of Production), not the date of install. Especially if this is used rig, and you don't know the full history of the tires on that rig.
- Damage can happen on the terrible conditions of our highways. Do take extra precautions if you have large impact, say a pot hole. And watch very close for the next month or two and or several thousand miles. A bruised/damaged cord can expand to a break or a bubble/bulge sometime down the road after such impacts. If in doubt, take it in and have it dismounted and inspected from the inside.

The only thing that moves you forwards, turns, or stops your coach - are those little contact points on the ground.

We pay for insurance yearly, because stuff happens. Look at replacing your tires on a 'time of use', as insurance. The difference, is by not doing so, you could cause serious damage to your coach, and or, serious injury to yourself or others.

On tire choices. Don't save money on tires, choose good quality tires that are rated for your coaches loads. Now, what you feel is a 'good quality tire', is your opinion - and OK to choose there brand that you like.

Safety is not accomplished by accident.

Opinions vary, I've shared mine!

Best to all, be safe, have fun,

Always hear that tire most be changed after ten years whatever the tread deep. Ten years on the road and six years on the rack (tablet), surprising.

Geneeal consensus seems to be 7 years. Learned the hard way. Bought coach with 12 yr old tires that looked fantastic and then left front exploded on freeway pulling coach from right lane across left lane and nearly into the ditch. Even michlin recommends dismount and inspection between years 7-10 for their tires.

I had to make the decision you are considering this past summer. My coach a 2004 Country Coach Allure had the original TOYO'S. They were in great shape absolutely no cracking and excellent tread, I had one of the tires repaired for a nail puncture, it was removed and examined at the time and appeared to be in excellent condition.
All of this being said I was preparing for a long summer trip, and when considering the risk I opted for new tires for the peace of mind. I kept the TOYO'S and examined them after being removed and everyone agreed there were no signs of aging. In fact a trucker saw the tires and bought them for his trailer.
I am confident the original tires would have made the trip. However as I was driving on that trip it was comforting to know I had new tires under me.
