Can I ask which size Spidertrax you went with? I have jba uca's and i think i'll have to do spacers to have these tires and clear the uca's

 

The standard 1.25” blue spacers.

 

Great forum! Very helpful info has been posted. My plan is to run 255/80r17 Flaken Wildpeak AT3W tires on my stock OR. A lift kit will come later on. Glad to know I can buy my tires now tho

 

Anyone else have rear end hop on highway spread over bumps while curve in the road almost $#%t themselves too? This was a scary thing and I hope new shocks would help this not happen. Looking at eibach lift and coils to hopefully play it down better.

 

Unloaded pick up trucks are notorious for this. That being said, my truck with Dakar HD's does it far less than my stock OR leafs did.

 

just some extra 255/85/16 shots from my install today.
2021 OR MT

This thread was awesome for the piece of mind knowing they would fit.

 

Alrighty 255’ers...

I’ve been checking my spreadsheet for about a year now (nope, no new C rated tires), and my stock GYs are getting close... perhaps another 5k miles. I’m not really keen on moving to an E rated tire, but wonder how rough a 235/85/16, or 255/85/16 in E would be. I’m 95% daily road, but really like the skinny military look. Plus, I will probably be trailering by next year a few times a year.

Anybody have a comparison opinion? My last experience with Duratracs were that they were quite loud. FJ wore them well though.

 

I feel that my 255 KM3s on 16" wheels has the slightest MT tire hum to them, but run SUPER smooth and don't feel any rougher than my factory Goodyears crap tires. I actually think they feel softer due to MUCH thicker tread.

No regerts.

 

I worry about hum, as my commute is anywhere between 65mph and 85mph. I wish there was a 245/85, but it’s either 235 or 255. What psi do you run?

 

I'm only 100 miles into some 255 km3's But this would echo my initial response.
I can hear them for sure at 60+ but it's not annoyingly loud or anything.
at 80 mph they might feel slightly more wandery/floaty.

other than that I haven't noticed a real loss in power or any nasty side effects so far.

once again, only 100 miles into them so ???

 

Is that a thing? Thinner tires wander more? Or is it the tread pattern you think might be causing it? Honestly, my GY Kevlars have been a great commuting tire so far. They do seem to deflate somewhat over time though.

 

it's hardly noticeable. I kind of put it down to a much bigger softer tire, and the fact that I haven't dialed in the air pressure. (I just got them installed, who knows what they set them at)

 

I’ve been all over the board for a year. Settled on 255/85 a while back. Then toned it down to 265/75. Then considered 245/75, but that’s stock height. Back to 235 or 255 now and leaning towards the Toyo ATIII in 235. I even considered rationalizing some T4R Pro rims in 17 for a better tire selection, but I couldn’t fool myself. I’ll get about 3.5 years out of whatever I get, so I’m trying to get it right.

 

I'd say the 255's are really not that bad at all.
even if I didn't off road my truck I would have done it for the look.
it was an easy choice for me, I use the truck off road more than on anyway.

If your 95% street driven with the occasional light trail, it may not be worth it.
But it really isn't as bad as you probably fear.

 

Mine are currently at 35psi. I will do the chalk test soon to dial in front rear settings to better suit the actual needs. The hum is just a noted hum that is evident from any mud terrian tire. Noticable, but by no means annoying or really any louder than the KO2's.

What is weird though, I read several times that 255's wander more than 285 tires. I can see that as a possiblity, but on the same stretch of highway that has stoopid studded tire grooves (at 60mph), I find that these tires don't push me back and forth in the lane like my stock tires always did. And these tires are a half inch narrower than the stockers. Go figure?

 

to be fair, I could tell zero difference in wandering below 80 mph.
around 80 it was probably just enough to be noticed as a difference.

also to note, the skinnier tires should be less likely to follow grooves in the road. this isnt what i really mean by wandering.

they just dont seem as stable at 80mph. once again this is an absolutely marginal difference im talking about.

 

Damn, so new you didn't even have plates yet

 

1,140 miles.
I drove it almost 1,100 exactly to get it home.
Literally the second day I had it.
I felt kind of stupid putting brand new tires on a brand new truck,
but here we are lol.

 

There should be a logical reason for what your are doing with any mod/upgrade on a given truck.
This is true with tire selection.

If you want bigger tires for the sake of bigger tires, then you will have to live with any side effects.
If you are still not sure what you want/need the tires to do, just wait until you are.

Let me give you my reasons for why I chose 255/85R16 BFG KM3 tires and zero offset 16x8 wheels.
I did not have to do a CMC.
I did not have to do a pinch seam smash-n-seal.
I did not have to run spacers to clear UCAs.
I only needed enough tire height in the new tire to keep my truck nearly the same ground clearance after airing down as I did with stock tires running street pressure.
A skinny 33 will put FAR less strain on the stock drive train than a wide 33, 35, or even a 37, and take much less braking to stop them than these other tires as well.
I needed a tougher tire than stock tires for the panned use of the truck on Oregon's rough desert trails, and rocky forest trails.
225/85R16 BFG AT KO2 tires are not an available option, as I would have preferred ATs over MTs.
However, KM3s seem to have reasonable mileage similarly compared to KO2s.

They should perform well within my expected planning.

As far as providing a percieved "look", well..I really don't give a crap for social validation regarding the looks that they may promote.
My tire selection fits my needs, and that is all that I need them to do.

Take your time and dial in what you need the tire to do first. After that, then figure out what you need to do to make them fit in all directions and perform as you need them to perform. If "looks" are important, make that the last thing you worry about.
