Does anyone have experience with Hankook AH37 tires on their coach?
-
Yes, I installed them last November on my 03 Monterey. Drove from Oklahoma City to Titusville Florida and found that I couldn’t tell any difference in the ride and handling from Michelin’s. May be a little more road noise on concrete but overall I am satisfied with Hankooks. Can’t beat the price going through FMCA, I paid $497.

Just be sure to verify the tire load rating you need is met (i.e. my front axle is rated for 15,300 lbs so I need tires rated for at least 7500 lbs each).
When I shopped for a spare tire, I found that are not a lot of tires that have a load range that works on my coach.
The load range is the second to last column for these Hankook AH37 tires (chart below).

The AH37 comes in a 14 ply G rated and a 16 ply H rated. The coach was delivered from the factory with H rated Toyos. I found some fresh from the factory for under $400 each.

I had them when I bought the Coach in 2014. Ride was fine and they held up with no checking or issues. I put around 30K on them. I replaced them with Sumatomos in June 2018. Sumatomos ride a little better and they now have about 10-15K on them. I would buy them!

I bought 6 AH37s through FMCA back in Sept 2019. Running the 75 series over the 80 series, and they ride great and the price was under $400/tire.

Andrew,
I assume that by saying "Running the 75 series over the 80 series" you were referring to the aspect ratio on the tire. If so and you are running 295/75/22.5 tires instead of 295/80/22.5 tires, and in doing so you have a tire with a lower weight rating, so you need to check your wheel loading and increase your air pressure to compensate for the lower capacity tire. On a Monterey this should not be a problem, but on heavier coaches like the Marquis, the 295/75/22.5 can be overloaded even at max inflation.
