4.88 Re-gear on horizon. Now looking at taller tire options.

[MENTION=109102]MattJakobs[/MENTION]
The gears will more than likely be 4.88. I think this is a good compromise for my needs. It won't crush my soul should I stick with 33" for some reason, and they should be fine should I go larger. I am not sure I want to listen to high RPM cruising 70 mph on the highway. At any rate, that should be just fine. I am still tossing around the idea of adding the front locker. That get's pretty close to eating all my fun money though. LOL.

Yeah.. We are in the same ballpark for sure. Haha.. Every time I look at the back or your and [MENTION=143526]theesotericone[/MENTION] 's rig, I feel like I could have gone the Savage rear swing out option. Hahah.. I got the notice that they were "in stock / ready to ship" after being on the waiting list for way too long and deciding to go 4X Innovations. Actually, I really love my bumper. The license plate location.. not so much.:dammit: Anyway. I might see what everything feels like with the 285/75/16's and make a decision from there.

I think that in some ways it would be easier to just go 315/75/16's No need to change wheels out for that jump. Tires are cheaper. You'd just have to do a bit of modding to make it all fit. If I were to do it over, I think I might have gone with a 17" wheel as more manufacturers focus on the larger wheels for their product lines. I really like the idea of the 285/75/17 option at 34.06". It is not really wide like the 35's... But... It IS more expensive and would require a wheel swap.

Hahaha, You are not kidding about going back and forth with the various points. And for me, this thread has multi dimensions to it. I figure it's just as much about gears as it is matching them up to ideal tire size for said gears. There's even a little supercharger perspective sprinkled in, (not a real option or desire at this time). I guess what I am saying is that I am not a thread purist, and this discussion will help others down the road brother.

I will play around with it some more and start crunching some numbers. Most of the highways I use around here have a 60 mph speed limit. Some get up to 70 mph when you head east. When I head east over the pass I can feel my stock geared (4.10 probably) 3.4 struggle to keep up with some of the other vehicles in the group. If it was just me, I wouldn't stress or push it hard to keep up. But with a group, I try not to lag too much behind heading through the mountains. I just worry that 5.29 would be great for that situation, and not so great for normal highway driving. Again. I need to crunch some numbers. For reference, I am right at about 2K rpms at 70 mph with my 285/75/16's. So maybe I will crunch some numbers for 315's and the optional 17" 285/75/17 to see what those look like at a 70 mph cruising speed.

I like the idea of 255/85/16's too, but they don't seem to offer much in the way of a height advantage over my 285/75/16's. I always had it in my head that they were a TALL 33" tire. But it doesn't seem to be the case when looking at ACTUAL tire height measurements. I think for a fair amount of what I do, they'd be ideal. But. I went with a couple groups this year during out winter months and hit some DEEP snow. One trip was a lesson in epic recovery. Five hour lesson. :gun6: If I lived further south, I think I would just go with 255/85/16's no problem. The only taller option for 16" wheels jumps right up to 35".

I have been reading the http://www.toyota-4runner.org/3rd-gen-t4rs/108367-official-3rd-gen-4runners-35s-pic-thread.html thread. I am trying to research what all would need to happen to make these work, should I want to go this route. I understand that most just tub the contact points at the firewall, relocate the windshield washer fluid tank with a smaller tank, but I haven't heard a consistent answer about the rear clearance. I have the SS extended bump stops. I just wonder if my wheels being a 3.5 BS would push the 35's out into the body, and maybe the filler neck guard. That is something consider and decide if it is worth it going up a tire size.

I could just run the same 285/75/16, and plenty do. I knew I shouldn't have started looking through the 35 thread. :ybrick:

I went with them for several reasons... My driving style and also less weight compared to the wider tire. Then of course I went and bought one of the heaviest tires manufactures on the market. LOL (Toyo)
 

Hahaha.. I think I might need another job or two to keep up with all you Joneses. All those options are really bad ass though. With so much focus on lockers in the Toyota world, it is funny that this doesn't have a wider following. A super slow crawl rate even open / open is pretty impressive. I don't imagine that dual case is the best solution in ALL scenarios, but man do they do what they do well.

Yeah, nothing is written in stone. When it comes down to actually picking a tire, size, and design, that will be hard. At least there are a lot of good choices out there. It's just that some of the choices follow a distinctly different route. Those Toyos have a strong following even despite their weight and price. They have to be just about the most expensive option out there in a lot of sizes. Well... most that I have seen.

Up here, I would say 80% of all MT tires sold are Toyos. Granted, a lot of trucks are used to pull trailers full of snow machines, 4 Wheelers, or Side by Sides, and not go off road much, but either way.... They are about the only thing sold up here.

I would've stayed with them, but the price for 5 35" tires was pretty steep and my bank account was lacking.
 
You just can't trust tire manufacture specs anymore . Here's a set of brand new ,unmounted Falken 285/75R16s . Apparently 33s are the new 32s. falken tires.jpg For what its worth my maxxis 255/85s were 33 1/8" tall when new and those Toyos are supposed to be 33 1/2'' .

That implies you could trust them up too a few year ago. Not the case. You can dig up articles from the 80's about tire size being a little small. Like I said upthread, there in no standard to adhere to in the industry. Change that and it will level the playing field. Not enough people actually care to do anything to affect that change though. lol

Yeah... Maybe pay them $87 for every $100 of tire. Tell em, "It's close to $100 just like their tires are close to claimed size." :banana:

Wasn't it Bill Burr what was complaining about going into a burger joint and giving them his order to be told that some of the condiments are "over there" to add to his burger? He was like, "I am giving you 100% of the money to make 100% of my burger! He proposed giving them less and saying that he was doing their job for them by adding requested condiments to his ordered food. Hahahaha:drum:

I do like this idea :cowboy:. In the construction world we call this undersizing " nominal " . A 2X4 is actually 1.5X3.5 , a 4X12 is 3.5X11.25 . Back to tire size, there is also 295/75R16 . That should be a true 33 and I believe General makes a a/t in load range D.

Yeah, I remember BFG's old 33x9.5 was just a little over 32" tall.

The only tires I've seen sit taller than the rated size are treadwrights. My brothers 35s sit above 35" on his 4th gen.

He rubs all over. 3" lift, 2" body, tubbed front with cab mount chop. Shop that did the welding work said if you want 35s you are going to rub.

IMO Roadbull if your going this far you might as well run 35s. It's like night and day on the trail when going over obstacles. Everything is easier and you get good clearance aired down compared to 33s.

You can get major clearance with some spcs ucas tuned forward. You can clear firewall on 35s street driving with zero firewall modification but will need some when fully stuffed but is minimal compared to any other aftermarket uniball arm.
 
I run a 285/75/16 Ironman M/T 10ply. So far love them in the mud and highway. Biggest thing tire rotation!!
why don’t you guys like the thought of runnIng a 305/75/16
I also have a set on 315/75/16 on my 12v cummins might take one off and toss it on my of my wheels for visual look. Humm
 
How close? Because you just let a little something drop in another thread. lol

What?!

This ol thing?

Well... I have had it for about an hour now. LOL. 4.88s with rear ARB. I am pretty stoked. I am about 55 miles into my 500 mile break in.

Sweet. Congrats man. You doing dual burnouts yet?

Who did you have do the work?

No burnouts yet. LOL. I went to a local guy, Nils Bull, here in Washington that just does diffs and was an ARB tech for around six years for them before starting Bull Built Differentials. He knows his stuff and is passionate about his work. He was happy to go into great detail the difference between getting it done, and getting it done right. Besides using solid steel spacers, he also utilizes upgraded shims to ensure to ensure the best possible job is done. He also stands behind his labor for 5 years. Two of my other friends have had their gears and locker done through Bull Built and are happy with his work.

He did a great job plumbing the airlines from inside to out and everything looks top notch.

The break in should go quickly enough as I commute to work. It shouldn't take too long.

So what's the verdict on the 4.88s? I'm picking up an elocker rear axle tomorrow afternoon and debating 4.56s or 4.88s. I don't plan on ever going bigger than 285s with this, and it sees a lot of 75mph interstate.

I personally liked the 4.88 combo with 285s. And I was running BFG KO2s which run on the smaller side of 33s. I would have been just fine with it as it was. I felt that the 4.88s made it feel a lot closer to stock gearing. AND.. that gearing with 285s was nice and slow in 4 low out on the trail for technical sections. I think 4.88s give you the flexibility to pick your size tire and be comfortable. I am happy with the gearing, even with the 35s.

I didn't think that the RPMs were crazy or anything at highway speeds. I thought that I wrote down somewhere what they were but I can't seem to find it at the moment.
