On our current motorhome in the last couple of years I have had Michelin made in Spain and on the drive tires Michelin made in USA.
Goodyear owns Dunlop and Kelly. I have two Dunlop tires on my coach made in the USA.
Yokohama tires are likely fine. But make sure they are made in Japan or another industrial country with enforced manufacturing standards. I have owned Michelin, BF Goodrich (owned by Michelin), Goodyear, Dunlop, and Firestone (owned by Bridgestone) in the last ten years on RVs I have owned. All worked fine.
I always try to buy tires made in the USA. This country makes really good tires and I want to employ Americans where I can. I would not put a China or India made tire on my motorhome it they were free. But that said my experience indicates that there are a number of good companies out there that make high quality tires.
The only reason I have not bought Michelin tires the last couple of times is their tires seem like they are 28% more money.
I seems like the RV specific tires made by Michelin and Goodyear have caused a lot of negative comments by people on this forum that have had problems with them. That has caused me to purposely buy truck tires and not RV tires. No "riveting" or "zipper" issues with truck tires that I am aware of.
And by the way, I am not a China and India hater. I have lots of stuff made in China that is fine. Like this Mac computer I am writing this post on. But if this computer goes out I go to the Apple store. Not much of a problem. If a tire blows it might cause $10,000 damage on my motorhome. And / or endanger the life of me and my family. So with tires I stick with stuff made here.
