255/85 R16 Owners Experience

Just out of curiosity. I read through some of this 200+ pages and found some opposing info on these tires with stock suspension.

My understanding is that the 255/85 R16 won't fit stock and at least a 2.5" lift is recommended.

I have a small lift, 1-1.5" I am guessing.

Exactly what trimming do I need to do? Is it as excessive as body mount chop? Or is it just plastic fender liners and mud flaps?

I have a 2011 reg cab 4x4 with 2016 TRD OR suspension giving me a little lift.

 

It fits stock on 3rd Gens. Are the wheel wells the same between generations?

 

Welcome PDXKid,

It seems the general consensus is that this will definitely not fit stock without at least some trimming. Typically bigger tires require mud flap and front, inner wheel well trimming. Hopefully someone chimes in if this requires more than just plastic. Good luck on your lift, there is tons of info on here, almost too much to sort through.

 

You'll probably need to do some trimming, and body mount chop. Lift doesn't have anything to do with fitting be tires, it only changes the static ride height of the tuck. The suspension still cycles through the same range of motion.

As far as what and how much every truck is different and it depends on wheels, tires, and alignment (mainly caster)

 

After some smarter searching, it sounds like I should aim for caster @ 3°, camber and toe @ 0°.

I want to run 255/85 R16 KM2s on my stock base steel wheels and stock UCAs with around 1" of lift.

Will my stock UCAs allow me to achieve these alignment specs? My searches for stock alignments typically end up showing non stock UCA with lift alignments.

 

For those of you (like me) who are interested in more AT options for 255/85R16s please go here and request that size from Treadwright in their Warden tread pattern...if they get enough requests maybe they will start making them...

submitted... although i really wish they had something newer and better than the old BFG design that's now 30 years old lol

 

Well, I went and bit the bullet and bought some of these 255 85 16's. Can't wait to see what they look like on the truck instead of stacked in the bed. The 200 plus pages I read finally convinced me to give a whirl.

 

What kind of lift or trimming modifications have you done TacomaStrength, if any? Man, I really want the tall skinny look and performance but just can't spring for the lift right now. Thanks.

 

If you like tall and skinny check out 235/85R16s...a bit skinnier and not quite as tall (32' instead of 33) but there are MANY MANY more choices of 235/85R16s than there are 255/85R16s...and I'm pretty sure you won't need a lift to fit them...

I think they look good on 2nd Gens too (not my truck below)...probably will put a set on my 3rd Gen when the time comes.

 

Lift has nothing to do with being able to fit larger tires. The suspension still moves through the same range of motion when lifted. Wheel backspacing, tire width/height and alignment are the things that determine fitment. You'll likely have to trim/ bmc but you should be able to fit these tires stock. Since they are skinny you don't have to worry about contact with the UCA

 

No trimming thus far; although, I tore the mud flaps of during the past turkey season in the woods so they might have to go. I have 3 inches of lift. Here is what they look like on the truck.

 

Be real- you just wanted your tires to say "dick"...

But seriously-- those tires are only 49 lbs!? That's 9 lbs lighter than my ST Maxx. Even the 285/70r17 are only 54 lbs.

The KM2's in your size are 55 lbs

 

My hunting buddies said the same thing.
I am curious to see how they hold up, but in the limited driving I did yesterday they rode fine. Even balanced quickly. The guy at tire shop was surprised at that. Definitely have that mud grip moan, and since it rained yesterday and is supposed to today, I'll get to see how they like that Georgia red mud this afternoon.

 

What are the pros/cons of a lighter tire? Better gas mileage but not as durable?

 

You got it!

A light P rated tire (although not available in this size) is going to give better mileage, but will be considerable weaker than an E rated tire.

 

Tires are unsuspended weight, so a lighter tire will be easier on all your suspension components and also being rotating mass will be easier on your brakes and drivetrain and even your steering as well. That's why all other things being equal (if they are strong enough), lighter tires and/or wheels are always better.

 

Yep but all of the tires I mentioned are E rated as well- so all will be as durable.

 

Update, got an oversand permit this week and drove out on dunes and beach. Ran the tires at 10psi, still no issue.
