I have done a search but did not find any info on Duramax tires. I have three of them and one Jung Lin? on our new/used Montana. The missing Duramax tire was the victim of a blow out prior to us purchasing it. The tread is good on them and there is no apparent cracking. Are these tires ok to run together? I have not been able to find a local dealer who can get a replacement Duramax to match the other three and then move the Jung Lin? to the spare.
Also, the max inflation on the Duramax tires is 108 psi. This sounds pretty high. The dealer we purchased it from has 67 psi in them by my tire gauge.
I am assuming you are talking about the 7.50R16 14 ply Duramax. I used to sell quite a few of these before they became hard to get. For an import tire they aren't too bad, better than the Jung Lin I'm sure, but not the best in the west. I would raise the air pressure up to around 80 to 90 psi, and keep a close eye on them, 67 isn't enough.
If you like that type of tire, I would recommend the Hankook F19 14 ply. It is very durable and very dependable.
Thanks for the info. I am ready to quit looking for a Duramax tire to replace the Jung Lin. Other than the Hankook, is there another tire you would recommend that I could start moving to? It looks like there are a lot of options out there.
