I'd be willing to bet that the tires wander more due to the size (narrow) than the additional sidewall tread. I run the little brother to the 255/85, the 235/85, and the narrow tires just like to wander ever now and then.. They like to find the low spots on the road.

OK...

Do guys think I should have him re-do it for 0 deg.? I mean, those values are in a unloaded but settled vehicle. If I throw mom, baby, dog, and stroller in the back, am in negative territory?

Any thoughts?

I think it also depends on the contact patch the tire creates. If the patch is taller than it is wide, as in tire width, it should hold a track better than a super wide tire that would have a wider-than-long patch.

FWIW, my stock A/T's were like magnets to the tracks in the pavement. If I was on the slope of the grooves at a stoplight, those tires would pull like crazy into the tracks. I haven't spent enough time on these new ones to see if it's more or less noticeable.

Hmm, did you get the alignment before this picture?

It's actually odd looking the more I look at it...

if you look at both from and rear tires from the front, as in, looking from the front crouched down, but just off to the side enough that you can see the rear tire, do they line up vertically?

I know "eyeing it up" isn't an exact science or anything, but that's what I did when I put my camber bolts in and I was pretty close lol But toe was off..

Anyways, those figures you posted don't really look familiar. I just got an alignment a few weeks ago. I'll dig out my spec sheet when I get home and post up my results.

But no, you shouldn't get it set to 0 degrees as you're probably close to 0 degrees with you and someone else in it, or even you alone. Being slightly in the negatives when you're fully loaded won't really hurt anything because how often do you ride with a fully loaded truck?

If you think about it, with it set how it is now, you're alone most of the time driving in it right? So you're close to zero. Some of the time if fully loaded, you might be in the negatives slightly. But that's only some of the time.

If you set it to zero, you'll be in the slight negatives driving alone, then even more in the negatives fully loaded. So you'll ALWAYS be in the negatives instead of back and forth under and over zero (which gives you even tire wear).

I think you're fine.

Does anybody know the acceptable range for the TPMS? Or, does it just trip below a certain psi?

According to the FSM the TPMS trips for these reasons:

- < 193 kPa (approx. 28psi)
- system malfunction (i.e. faulty sensor)

It is designed as a Low Tire Pressure Warning System. There is not an upper limit or range; per se. That isn't to say that you could fill your tires to 100psi and not have a TPMS issue.

The system will alarm for each sensor it recognizes as being below limit; 4 times when you air down for example.

Thanks, guys. The TPMS had fallen off the wheel in question. I'm all set, now

Yes, those pics are post-alignment, as shown in the print out. I think they line up fairly well but there's definitely noticeable positive camber out front, unloaded.

Keep in mind, those specs on my sheet are for the Off Road with the 265/75's and he adjusted me to the middle of that range. I suppose I could have him re-align me a little more to the negative (or close to zero) to compensate for the taller tire but we'd really be splitting hairs.

How much did you pay for the tires?

 

[nichthupen]

whatever tire rack charged, 189 a tire, I think, plus their heavy shipping.

WOW! I love it man!

I know this is a old thread but I found it when I did a search for your tires. Anyways, what are your thoughts on them after 1 1/2 years? Any complaints? Would you go with the size if you could redo it all? Just curious because I am in the process of deciding between 285/75/r16 and the 255/85/r16 BFG MT KM2. Thanks for your help!

 

[westracing01]

285's are on national back order for right now. Everywhere I've looked they aren't available. However, I too am interested in feedback regarding the above post from anyone else with long term experience. The OP of this thread hasn't been to the site in over a month.

Good on you for searching too!

I know it's the BFGs that you guys are asking about ... but: I've had my 255x85r16 Toyo Open Country MTs for at least a year now (I'd have to double check records for exact install date), and I've been extreemly happy with them.

They've probably got somewhere between 15k & 20k miles on them and still show plenty of life left. They've gotten a bit noisier over the time I've had them, and have needed up-to-date rotations and occasional re-balances; but it's not something that has been an issue and IMO any tire will likely need that over its life, especially MTs.

I've also been fairly impressed with their winter performance. I felt like I was taking a bit of a gamble on how they'd do in the snow, when I first got them, and was fully prepared to regret the decision; but I definitely haven't. They've always been at least as sure footed as the stockers in the slick slush/snow (and obviously much more so offroad).
