On a previous MH I replaced GY's with Toyo and was very happy with them over the GY's which I could not get balanced. The GY truck tires which came on this MH were made in Germany and had a good rep unlike the GY G670 RV tire that often rivers. At eight years I replace my GY 295 front tires with a bigger Firestone 315's and at 10 years I replaced the rear with slightly smaller Hankook 11R22.5. Very happy with this combination and I did not balance the rear six.
Here are
292 posts on Hankook tires in the last year in Class A.
I WAS a loyal Michelin user for over 40 years but I will NOT buy another after the way they would not warranty the early XRVs that actually blew out sitting still. Guess that's better than all the ones that blew going down the road and it was always the owners fault.
PS: I put the 10 year old tires off this MH on the back of my 10 wheel dump truck as I could not find any cracks or other problems when I dismounted them. They are much better than the recaps I replaced.
No, I am NOT suggesting that you should go more than 7 years BUT I'd put almost all the miles on these tires and I'm anal on weights/pressure/inspection.
