Noob tire question.

I'm sure it's been discussed, but after extensive research I cannot find an answer.
So I'm going to be lifting my truck this weekend and I'm trying to decide on what size tire I want to run. I have a 2014 DCLB. I'll be running 5100s all around, with OME 885s and Icon progressive AAL. I also will be putting on the SCS Stealth 6 wheels, which from my understanding stick out a little and allow a bit of clearance. I am NOT changing my UCAs. Thus prompts my question. 265/70/17, or 275s of the BFG KO2's.
From what I understand, with that suspension set up, I can get away with minimal to NO trimming when running 265s on stock UCAs. I'm wondering if someone with 275s and a similar set up got away with minimal to no trimming as well. I like the look of the 275 over the 265. Looks a little chunkier, a little more aggressive. But if it's going to require a lot of trimming then I have no issue with the 265s. Hopefully someone can help me out before I blow $1000 on tires that won't work out. Thanks.

 

Considering the width difference is about 1/5 of an inch and there are a few 275 width tires that fit stock I would assume you'll be alright. 275/70-17s will fit. And pounding the pinch weld over is a lot different than having to do a CMC and weld a new piece in. Do it anyway.

 

Gonna show the math to support what your decision might be.

From what i understand your choosing between 265/70r17 and 275/70r17
First number is the width of tread in mm
Second number is a % of the width = 1 section of sidewall
Third number is your rim in inches.
25.4 mm =1 inch

So (265 x .70) x2= 371÷25.4 = 14.6 +17= 31.6.
Overall tire size is 31.6x 10.4r 17

(275 x .70) x2= 385 ÷25.4= 15.15+17= 32.15
Overall tire size is 32.2 x 10.8r 17

If you have the option i would go with the 275 as long as you have a somewhat positive offset. Otherwise you will be rubbing that control arm. I am running 33's in a 275/60r20 with a +18 offset and wish i could have found a +25 offset wheel i liked. Very minor trimming.

 

The offset for the Stealth 6 wheels is -10mm.
They are 17x8.5 with a backspace of 4.3".
Just worried about rubbing on the control arms, and I also worry about doing the CMC mod. I have no experience welding, and I'm not interested in forking out the extra cash for either new control arms or the weld job. I've already spent enough money

 

If you don't want to worry about CMC go with 255/75s or even 255/80s.

32" and 33" tires respectively. And will do better for you in most conditions.

 

On my truck the stock wheels are 7" wide with 5.5" BS and +32MM offset. Basically the outside of my wheels are only about 1.5" outboard of the hubs. I can for sure run 32" tires with a 10.4" section width with no rubbing anywhere at full lock. I should be able to run a 33" 255/85R16s by only removing mud flaps and taking a hammer to the pinch welds. The outside of your wheels, on the other hand, are around 4.5" outboard of the hubs. The radius of the arc your tires will describe at full lock is a full 2.5" larger than the radius mine describes for any given tire diameter. Maybe 2014s are built a different than 2011s. And maybe I have my math wrong, I'm no expert. But if not, maybe you have screwed yourself already.

Edit - 3" larger radius. Doh!

 

I believe 2014s are the built the same as the 2011s. I also believe your math is correct. What information I've gathered from asking fellow TW members as well as reading threads, 265s typically fit fine with the particular suspension set up I will be running. Seems like 265s fit even on the stock suspension. 275s seem to be another story. Some say they'll fit. Some say I'll need UCA's. Some say minor trimming (Remove mud flaps, plastic liner). Some say a little more trimming (CMC mod, hammer the pinch welds). I'm just hoping someone with the exact same truck, with the exact same set up can tell me yes or no haha.

 

I'm happy with 265s either way. Lighter load rating giving a little better mpg. 275s just look a little better cosmetically imo, though it's not much different.

 

I will be surprised if you dont rub with 31" diameter tires.

 

With the -10mm offset of your SCS wheels, you won't rub the UCAs with 275 tires. The rubbing will occur at full steering lock at the plastic fender flare where it wraps around the bottom. That portion of the flare will need to be trimmed away.

OZ-T runs 275s on stock TRD Sport 17" s with no rubbing.

Note: I would recommend a more thoroughly modern tire than the KO2s, something like Hankook ATm or Goodyear Duratracs.

 

Ugh, this is exactly the reason why I'm confused. One person says I can fit the 275s fine with no rub. Another person says I can't even fit 265s without rubbing! Halp.

 

Sorry man. Im just calculating and making an educated guess.

You already gambled buying the wheels without being sure what would happen. So go big and finish the bet by buying the tires, mounting 'em, and see what happens. Maybe it works and you win. Maybe it doesn't and you sell 'em and try again.

 

Go 255 and thank steelhd later

Or (why is there no hammer emoji @tcBob ?) and

 

I think his new wheels are too wide for 255s. Plus, at over 33" his wheel offset would pretty much guarantee failure at full lock.

 

I'll make them fit before I ever resell them!
There are plenty of satisfied customers who've purchased the Stealth 6's from SCS here on the blog. Most of whom are running 265s. Just thought by lifting the truck roughly 2.5 inches I could get away with 275s

 

When I purchased the wheels, I had the intent of running 265s. Before I even purchased anything (wheels, suspension) I talked to a few different TW members running the exact same set up I'm putting in this weekend. But, suddenly I want more!

 

IMO the drawbacks of 275s far outweigh any benefits. 275s are significantly heavier in the KO2 vs 265s. I don't believe KO2 275s are even available in C-load. So for a significantly heavier tire, you lose mpg, acceleration, braking and with the E load rating you also have a much harsher ride. You also have potential rubbing issues, requiring cutting/hammering all to gain 0.25" ground clearance over 265s.

You must be confused between the KO and the KO2. The KO2 is light years ahead of the Duratrac.

Nice truck man!

But that's basically what I was saying earlier. I would only be getting the 275s for looks, definitely not the functionality. I like the 275 because it's slightly bigger, giving the truck a little more of an aggressive look. But tbh, it's not even really that big of a difference. And yes, the KO2s only come in E class with the 275 and up.

I think the 265s look absolutely perfect for the dcsb. But being that I have the dclb, I'm afraid it'll look a bit awkward. Sorta like how the long bed looks stock.

 

Short beds look stubby and stupid all the time haha.


From reading your posts it honestly sounds like you should just go with the 265s and be happy with them.
