Mine are E load if you are asking. Which is overkill and makes the ride slightly stiffer. Not enough to really make a whole lot of difference unless you're hyper sensitive to it.
Yeah, unfortunately with the rig being so new there is not a whole lot of "perfect" info on them. When I bought the tires I was under the impression that 285/75/17 were the largest tire with no modifications, I ended up going with 285/70/17s of the Mickey Thompson based on price at the time...
That's a lot of weird unsolicited commentary to just ask a question about tire size..
Anyways here is my SR5 with no stock suspension and no mods on 285/70/17 on stock SR5 tires with no lift or any other mods. Completely stock setup other than tires. They do not rub at all and the ride hasn't...
I do not have a spare for it at the moment, I am still piecing together what I would like to do when it comes to that. However there is this post that shows the spare and states that the it can fit up to a 33" tire...
I haven't really driven it a whole lot since getting the tires put on other than the trip home. I didn't notice a whole lot to speak about though. a little grippier and SLIGHTLY bumpier but not a whole lot to where I would have noticed if I wasn't being hyper aware on the drive home.
