Sumitomo tires have been used in the trucking industry for decades. They have an excellent reputation for mileage and durability. The only thing I have found is they don't offer a high enough load rating for my coach's front axle in the size required.

I'm running a set of six in 19.5" on our coach. I have about 2,500 miles on them so far. They are a well known tire in the trucking/bus industry. They have a large distribution network for warranty issues too.

I have one that may not be totally round, but it's not bad enough to effect handling or control. I just hear it on some road surfaces (very smooth asphalt).

There have been a few posts on the forum and owners have been quite satisfied with them.

Great thanks for the responses. I put a st on the front yesterday with the balance beads and I felt as if the coach handled so much better. It took about 5 minutes for the beads to settle in after that everything smoothed out. Less steering wheel shake. The old tires were a little out of round.

Have had a set on my Winnebago Journey since 10/2012 and have 2 cross country trips and who knows how many Florida trips and football games ect. ect. and after close to 40,000 miles they still look and preform like new. By the way no balance beads. Would replace them with the same brand in a heart beat. I wouldn't buy a set of the original tires that came on the rig when new, you know the name.

Yep I know the name. The tires on the rear have previously been replaced. I had to do the front again due to being out of round and the aggravation that comes from that. Thought it was the alignment or something else wrong. Had the alignment and front end checked and all is good. The shop put dials on tires told me that was causing the vibration and pull to the right
Went ahead and replaced them at another shop and its amazing how much better the ride was. Less tension in my neck and shoulders driving now. Lol
