The SKINNY on skinny tires

Now running St Maxx in 255 85 16, put flares back on and painted steelies! Absolutely love these Coopers! I could stud them for $8 a tire at a friend's shop but probably won't... I just pack some V bar snow chains with me everywhere!

Cheers

 

You got any wheel spacers?

I've got the same rims, but with my new OME lift and LR UCA, it's gonna be close as to whether or not i need a spacer.

 

Any lift? I'm looking to run the same size.

 

I am seeing about 15-16mpg (assuming my math is correct)

I have a full OME lift and SpiderTraxx spacers to go with my 5 255/85-16 Cooper ST Maxx (spare is mounted on bed rack)

 

did you happen to do the LR UCAs? I went with the full OME with 887, Dakars, and LR UCAs. I've seen some go with spacers for 255s and others without. I know it depends on the wheel, but i'd like to go without spacers if i could. Just trying to find someone with the exact set up i have.

 

Can you fit a full size spare under the truck?

 

Yes, 887, full Dakar, Wheelers super bumpstops with u-bolt flip and SpiderTraxx spacers on stock TRD wheels

I went with the spacers for the slightly wider stance.

 

I've been running 255/75/17/C BFG KO2s for a month now. Here is some information I will share:

The facts:
- 2007 Access Cab V6 4WD w/ shell and protective bed mat, no steel or wheel accessories, 2017 TRD Pro Shocks, All-Pro 3" leaf packs, 5/8" front spacers
- Replaced 285/75/16/E BFG KO2s
- I used OEM 17" 4Runner Trail Edition alloys (17" x 7"/4.5") to replace the 16" aftermarket alloys that were wider and had about 0.8" additional offset (didn't know brand)
- Zero rubbing
- My MPG went from ~14/15 to between 18.5 and 18.9 (measured 3 times so far)
- I run the 255s at about 34 PSI, previous 285s at 35 to 40 PSI
- Added a used 255/75 Wrangler spare, which fit in the stock location with about 0.8" clearance from the exhaust (I have a Flowmaster, but original hangers)
- To get the spare to fit, I used a T-bolt hose clamp to keep the exhaust in place on the last hanger bushing, it's a clean 1" distance from the tire; without a mod like this, it would have rubbed
- I paid $801.62 for all 4 tires during the Discount Tires $100 off event before Black Friday, and bartered for free mounting by trading the old tires off the 4Runner wheels I purchased with a non-franchise tire shop
- No snow, sand or mud experience yet

The feels:
- The ride improvement is unreal, E-rated tires are history for my truck; I didn't know how sensitive I was to a crappy street ride
- Went from 24/7 dirt road, feeling every nook and crack, to much more SUV-like; you still feel the road like a truck does, but less annoying
- There is still that feint KO2 wub wub from the aggressive tread blocks (expected), but it is quieter
- The smaller tires and 15mm reduced offset from 4Runner wheels looks a bit odd at first; it's much closer to a stock look
- There is a noticeably smoother ride off road, but anything exceeding dirt road bumpiness will still demand a good suspension system

 

How come no love for 235/80 R17?

 

I'm considering 235/75-17 for my next set. Most likely Michelins as I don't do the off-road thing. The 245/75-17 would have been an option but they're only available in an LT E-rated. Running TRD Sema wheels, 1" farther out than stock with 265's, I'd like to bring the tires in a little behind the mud flaps.

 

Currently have 265/75r16 Ko2 and looking at the 255/85r16. I would rather not change rims as I like the stock aluminum ones but for that overall diameter and width does anyone have thoughts/recommendation on a 17" wheel? Is it worth the expense of new wheels? I had looked at a 245 in a 17 but really prefer the 255. thanks,

 

I ran the 235/85r16s Toyo AT II for a while and they were really stiff for the Tacoma. No advice on the 17" but maybe similar. The tire was great but just a little too narrow for me. If I was stock height it would have been better but with a lift it just looks like too little a tire

Edit: I ran the calculator and with a stock truck I bet that would be a great size!

 

Thanks. I'm lifted a little over an inch so appreciate the perspective.

 

My 4Runner on Cooper ST Maxx LT255/80/17 tires

 

Did you ever get an answer with this?

 

Nope. I went with 265/70 17 Wildpeak AT3. Awesome tire.

 

I finally get to join this thread. Got the email saying my tires shipped. 235/85/16 Dick Cepek Extreme Countries. I ordered them Dec 4th $200 off a set of 4.

 

Finally did it!! Brushed Gold SCS Ray10’s on Falken Wildpeak AT3W in 255/80R17 on stock 2014 SR5 suspension.

 

Well I got my skinnies haven't put them on the truck yet but I did mount them on the wheels and took a couple pictures. Here they are with the stock 265/70/16and next to a 31/10.50/15then loaded up for the ride home.

 

Put the skinnies on tonight. I was going to wait but thought I should run them a little bit to be sure there aren't any problems with them. One from the front. It's dark out so pics from the garage.
