Tires

Looking at summitomo lt285/60r 20e tires. Good price and warranty, has anyone used their tires.

Your going to open a huge Pandora’s box with that question.

Do a search on the site for Sumitoma and you’ll see plenty of comments.

#1 thing to do is to learn how to treat your tires -

1. Get your coach weighed - loaded as you intend to travel. Use the CATScale app which will at least give you front/rear axle weight. There are plenty of threads on here about how to get your coach weighed.
2. Get the tire pressure chart for the tires your using and learn how to read them.
3. Never check your coaches tire pressures “hot” (if you’ve driven over 35mph for more than 5-10 miles).
4. Exercise your tires. Take the coach out for a spin - maybe 1-2 hours a month at highway speeds (of course after checking the tire air pressures).

Sumitomo is not a brand that is regularly sold in my area of the world. I have seen and even sold them several years ago. They were generally a very cheap tire and definitely not problem free. I had a greater than average comeback rating with broken steel belts and bulges in sidewalls. This was all on car tire applications, but it still warrants attention.

Maybe they improved, but I'd probably steer you towards a brand with a more reliable track record. How much is your tow vehicle worth? How much is your safety and peace of mind worth?

1000$ for cheapo crappy tires vs 1500$ for MUCH better, safer and longer lasting tires...

I've never used that size but the brand is very popular on haulers websites in 17"/18" LT sizes for one ton drw and srw trucks pulling trailers for a living. Same with 19.5"/22.5" Sumitomo truck tires.
I would assume the 20" LT sizes would be just as robust.
