The SKINNY on skinny tires

I think I'm leaning towards the Duratracs 255/75/17. They only weigh 40 LBs a look pretty aggressive.

Saw a couple pics of this size but would love to see some more set ups!

 

Just ordered 255/85R16 Toyo Open Country M/T's from Discount Tire. Should be in Today or Tomorrow. Will upload photos once installed.

 

Considering that same size in the Cooper AT3 4S, great initial reviews and comes in at 39lbs.

 

It is done. 255/85R16 Toyo Open Country MTs. Zero rubbing or clearance issues for town driving. Ill test full suspension cycle next weekend and then take it offroad that week.

 

Yeh would love to see anyones set up running the 255/75/17 cooper discoverer a/t3 or learn how their liking it.

 

Alright folks, I've got a 2017 SR4x4 Access cab. It's time to get rid of those stock tires. I'd like something with a more aggressive look, and I dig the concept and look of the skinnies.

Right now I'm wavering between a 245/75r16, which I believe is the size of the smooth vespa tires on there now, and beefing up to a 235/85r16. I wish there was an 80 option. Rubbing seems to vary among the threads. Would I need to re-gear with the 85s? Just how bad would my mpg drop off be? I'm hoping to just slap these puppies on and be done with it.

Basically...help! Continuing to crawl through this long thread and the sub-links. Thanks for putting this together everyone.

 

Pretty sure someone above said 235/85r16 fit with no trimming on the stock suspension, hence that’s been what I’ve been hoping to upgrade to.

 

Yeah I was looking at some of the other threads mentioned in post #1 here. You heard anything about re-gearing needed?

 

255/85/16 ST MAXX on Ray 10.
OME 888
5100 all around (at zero setting in front)
Medium Dakars

No rubbing yet but I haven't taken it through anything technical requiring 4x4.

 

Not with 235/85r16, I believe most folks start re-gearing around 33’s (e.g. 255/85r16)

 

When I got my truck a couple years ago, the dealer had put on Yokohama Geolandar AT-S tires at 235/85r16. I haven't driven it on any other size tire, but I don't feel like I need a regear and there's definitely no rubbing. I've been pretty pleased with them, though I'll likely be looking to get some Cooper Discoverer XT/4s before either this winter or next winter.

EDIT: I've been on stock suspension the whole time

 

Anyone running 255/85/16 on the 3rd gen OR steel/spares 16x7. How much can I air down without breaking the bead lock?

 

I would imagine that if a 255/85R16 Toyo MT measuring in at 33.5"x10.2" doesn't rub then a skinnier shorter tire (235/85r16) measuring at roughly 32"x9.5" definitely wont rub. Also, I would say you wouldnt need to regear. Thus far the 255/85r16 doesn't drive me to want to regear. It rides plenty fine and still have plenty of power when I want it.

 

You guys have me pretty darn convinced. Should I be thinking about spacers? I imagine the upside is getting the wheel more flush with the flare, and the downside is...increased probability of rubbing?

 

And more points of failure. You need to be super diligent in checking them every so often.

 

You will have to try them without spacers, then if you want more poke buy the spacers, and if it rubs, ditch the spacers.

 

I just found this thread but scientifically speaking a narrower tire is not better in sand or mud or snow and is not better aired down.

Mud and sand are all about ground pressure, a wider tire reduces ground pressure and keeps you above mud and sand. While a narrower tire will sink in and get stuck. This concept applies to tanks and tank tracks. Wider tracks reduce ground pressure making them easier to move in mud. Snow is another monster a wider tire will generate more traction than a narrow tire as snow requires a greater contact patch. This is why arctic trucks have 20” wide tires and look like balloons.

Narrow tire has the same side wall as a it’s wider brother so the argument is moot. Over stock yes it does but side walls are weak offer no traction as a radial and only opens up vulnerabilities that a wider tire would otherwise avoid.

The only benefit to a taller narrow tire is looks.super awesome thread but a bit misleading.

 

Interesting... quick Google search seems to refute your statement.

Point being traction is dictated by pressure per square inch or contact area.
The skinny tire has that.

The wide tires have a lot of square inch coverage but lower preasure per square inch.

Thanks. Probably not worth the the hassle eh? Now for tire choice. BFG's, Falken's, Cooper, Hankook...comparing weights at the moment (mpg consideration)
