Use Case: SL vs E rated Tire (3 Viewers)

[hoser]

Some manufacturers list both the section width and tread width in their specifications.
Take a look at the first tire on the left.
245mm is 9.6 inches. Which spec is closer to 9.6”?

Ok, I can see I misinterpreted what you were saying originally, and learned section width is a thing.

And going to what I said to the OP, the tread width of the 275 can be wider than the 285.

E rated tires must run minimum of 40 PSI to prevent any potential cross-ply damage. I went from E to SL last month and at 29 PSI as Toyota recommended.

Makes sense to a degree. However, I ran mine at 32 psi for 35k miles no issues.

It really depends on your application though. Again, call and email the tire manufacturer for their recommendation, especially for a different size tire than OEM. It could greatly differ from your expectations.

For example Mickey Thompson recommended 28 psi for my D rated 37s (different vehicle). There’s more variables at play than most of us are aware of so it’s best to just ask the people that make the tire. if you’re worried, get it in writing from them.

Just my $0.02 but I'd stick with E rating if you're doing 6+ trips a year. I've sliced a few sidewalls over the years and a friend obliterated one one our last trip to Moab which led to more damage.

Yeah I'm right on the border there, 3-5 trips a year, but heavily weighted down when I am on those trips. Daily driving isn't the most comfortable and pleasant compared to stock, but the last thing I want to deal with is a hi-lift jack on the side of a sloped trail. Whew.
