Paul, Not sure what size tires you have but if their 16" there is no doubt I would buy Goodyear G614's. I have had three 5th wheel and all have had G614's and they are American made. I would never run a China made tire. There have been hundreds of major tire damage done by the China made tires. Michelin and BF Goodridge also make tire for the lighter weight 5th wheels.

Hope you didn't have a lot of damage to you RV. We are on our last stop before being back at Home base, we have covered about 6,000 mile + and have seen in almost every RV Park were a tire had blown and done several thousand dollars in damage. In Oklahoma City, while walking the furr kid and came up to a Montana that was 6 months old and had done about $4,500. I said bet your tires are Mission Tires he ask how did you know, then I told him about all of the major tire failure that has and is happening. He said he hadn't heard of these problems, I told him of the Montana Owners Group and he will get plenty of information there.

We now have a 2010 Mobiles Suites and I'm now running Goodyear 17.5" G114, have only ran about 10,000 miles so for and they have shown no wear at all. I ran a set of the Goodyear G614's 22,000 miles and they showed very little wear. Good Luck with your research. GBY...

We have had 2 blow outs in the last 3 months.  Our camper was bought new 11 months ago, and probably has less than 8000 miles on it.  We have decided to replace all the tires, but don't know what with.  What are you running on your 5th wheels?

Well, it depends on your rig naturally.  But since you’re asking for opinions, here’s mine:

First, I run Goodyear G-114 “H” tires.  (Same “upgrade” from “G” tires Howard made on his rig.)  This is an upgrade from the “G” tires that came on my rig.  It required new wheels.  I.e. “rims.”  Well worth the money IMO.

I have 21,292 miles on the new “H” tires.  Of that mileage 11,500 miles included a recent trip to Alaska up the Alcan and the Taylor Highway toward Chicken, AK.  I had zero problems on that trip. We will leave shortly for a 5,000 mile trip out west.  Tires are in great shape and I have no reason to change them for that trip.

I, based on a lot of reading, am convinced “G” tires are not up to some of the loads they are asked to carry.  I did have 16,394 miles on Goodyear “G” tires before I upgraded to the “H.”  They were giving me no trouble. But I was just leery, so I upgraded.

It is critical that tires be inflated to the proper air pressure as has been noted.  I always check my tires at each stop for excess heat.  I do this by hand and based on experience with an infrared thermometer, if they are running hot, I would know and do something about it.  (Get the Pressure Pro monitor if you like.  That’s another discussion.)  Excessive heat is a dead giveaway about a lot of tire issues.

Just in case you are not aware, tires, at least those for which specifications are "actually published," have speed limits.  Many trailer tires are speed rated only to 65 miles per hour.  The G114’s “H” tires are rated to 70 MPH.  I don’t drive that fast.  But the point is, there is a tire speed rating and it matters a lot as to how much the tires can take – especially on a hot day at speeds that may be right at the design limits.

I recommend you read Howard’s section on his tire upgrade.  He provides lots of good, and accurate, information there.

Again, knowing nothing about your rig it is hard to make other comments except to say, cheep tires are not a good thing.  A friend blew 3 tires on a recent trip with us.  Reason: bargain tires that were barely within the specifications needed for the job.  Result – flat tires.

Safe travels

Bill
