Tire size difference

[JlRubicon13]

Might be a silly question but what is the difference between these two sizes? Is there a reason that the E rated one has a deeper thread? I’m looking into buying one of them but I’m a bit confused on the sizing

That's really interesting. The first one is not a LT (light truck) tire, it's a regular passenger tire - SL load. I've never seen one made in that large of a size before. That would give a great ride on pavement and be great at fuel economy, braking, acceleration, etc. but most would not consider the sidewalls to be tough enough for serious offroading (depending on your driving style and terrain).

The second one is an E load LT tire. Light truck versions of all terrains usually have deeper tread than the passenger versions, so that's common.

Okay that makes sense. Are the sidewalks on the SL that weak? I do around 350 miles on the highway weekly but also do some off-roading. Currently I have the STT PROS and although great at off-roading, they are way too loud. The other option that I am looking at is the terra grappler but E rated instead as I can get them at a good price.

Depends on your driving style. I offroaded fairly heavily on XL load (halfway between SL and a LT-C load) passenger tires for 7 years with no problems but I'm a precise driver and always mindful of where the sidewalls are vs the rocks. I had a friend with my same tires who just pointed his vehicle down trails and drove. He got flat tires. That was with small Cooper AT3 tires though.

Nittos are heavy tires by default and the listed weight is oddly similar to the E load, so I suspect they might be heavier duty than "ordinary" passenger rated tires. In fact, I suspect they're fairly close to C rated tires. I'd give them a try.

The LT tire weighs 66 lbs.

What’s the weight of the SL tire?

That’d be a key decision factor.

They are basically the same weight. I would rather sacrifice some off-road durability and get something that’s a little quieter on the road. But also want something that will survive when taking off-road.

First one is Light Truck, this tire would be found on F250/350 level truck.

The second one is some kind of an All-terrain tire but not full max traction setup...my guess.

I would go with the 2nd choice over the first if you do any OR at all.

Maybe you should call Nitto as I wonder how they can be the same weight. My guess is it's new and someone copied the info from the LT tire by mistake.
