35in Trail Grapplers

[mrtifftiff]

I am in need of a new set of Trail Grapplers and I want to get a set of 35s. I currently have 285/65/18s and get ever so slight of a rub up front at full lock. I am guessing that things will need to be chopped to fit 35s but I was wondering what my limiting factors would be. My current 285/65/18s are 32.83" tall and 11.93" wide with no problems. I am trying to decide between 3 different sizes. The 285/75/18s are 35.08" tall and 11.26" wide; 295/70/18 are 34.57" tall and 11.73" wide; 35x12.50 are 35.04" tall and 13.39" wide. All things being equal I would want the widest 35s avaialbe and I was curious if the 35x12.50 are too wide at 13.39 inches. I have spacers up front, shrockworks front, Icon UCAs and TC LCAs. How wide can I go?

My personal vote for which would fit the easiest would be LT285/75R18, but because you want wide, go for the LT295/70R18

There will need to be a lot of work for 35s just ask [MENTION=49845]marshall[/MENTION]. I am running a Trail Grapplers in 285/75x17 (34.1) and it took some cutting to get it to work off-road.

The extra weight of the tires are going to wreck havoc on the spacer lift too in my opinion.

Your truck so your call. Get what you want and make it work.

My thought process: I have accepted that I will need to chop something more than just a fender liner to fit 35s so I might as well go all the way and get the widest 35's. Is that flawed logic? I suppose if I follow that line of thinking to its conclusion, then the 37x12.50R18 are 36.77" tall and 12.52" wide. Too much of a good thing? Assuming major cutting, how sluggish would my truck be with out re-gearing to the 4.56s?

edit: this was more of a joke. 9/10 joking. I don't want to regear yet.

1.25" Wheel spacers. Icon ET/Billet UCAs Total Chaos racing series LCAs. The wheel spacers were mandatory for the TC LCAs.

You're going to have to cut the body mount, cut the fender mount, hammer the pinch weld, remove pretty much all of the plastic from inside the wheel well, lower the bumpstops, lose your fender flares, remove your windshield washer bottle, and you're still going to rub pretty bad on the sheet metal inside your wheel wells.

I have done all of that, except for the fender flares, for 305/70/17s (34.1x12.2), and still rub. Also, driving it is going to suck without re-gearing.

You really really need to read [MENTION=104049]marshal[/MENTION] build thread. He ended up needing to roll his fenders along with major cutting. If you will be taking it off road it needs to be done right and marshal did. Also you need to re gear to have any semblance of normalcy. If you are not taking it off road ever the get a 6" body lift and put the biggest tires you can fit to take you to the mall.

I'd save your pennies and just do a SAS when you can afford it. I've had a daily driver on toyota on 35s and it was fine, but it also had 5.29 gears and solid axles. I'm not sure a 5th gen on 35s with stock gearing would be very good for regular driving. I just can't see the front diff standing up to any type of heavy offroading with 35s anyway. Stock 8" front axles aren't up to the task under a 3,000lb pickup with 100hp, but they can be built pretty cheaply. Not sure what you could even do to make the ifs any stronger.

After reading marshals thread, I am more encouraged than ever. the 295/70s are only 2 pounds heavier than my current 285s and my truck drivers just fine without re-gearing. 35x12.5 is probably pushing it but even then I don't see the additional 84lbs(edit: on second thought, I am probably grossly under rating that much weight) of unsprung weight to absolutely require re-gearing, although to be fair it would be quite noticeable. I think I am going to go with the 295/70. I think marshals cutting was pretty excessive, but we will see what is required for a 34.57" tire.

My truck is anything but a mall crawler. Function over form, ALWAYS!

285/65R18 Q 70 lbs 32.83"
295/70R18 Q 72 lbs 34.57"
35x12.5R18 Q 81 lbs 35.04"

I mean if you can find a way of getting 35/12.50s to full stuff with the stock fender arches and not going long travel, I'm all ears. As it stood when I got them originally mounted, they worked fine on the steet in a straight line. If I hit a curb to hard when I was turning into s drive or parking lot while turning, it was tire vs body the whole time.

With the fender rolling I can do full stuff Offroad. If I were to opt for full 3.5" long travel I could potentially fit smaller 37s without much involved.

That's just the front though, the rear is a whole 'nother animal.

Personally, if I'd have known what I was getting into I would have stayed with 285s. The 35s are heavy, unruly tires and the performance of my truck is terrible without regearing.

I would advise you not to do 35s unless you can do it all, and do it all right

Does the diameter of the tire alone need to be considered when factoring in the need to re gear? Going to 295s, which is a 34.57" tire, only adds an additional 8 pounds of unsprung weight to my current setup. I am happy with the way it drives right now, no rubbing at full extension/lock, and I can not see the requirement for new gears.

No, not alone, but tire diameter affects your overall gear ratio. Adding unsprung weight, air, and rolling resistance all also work against you.

Am I misguided in my pursuit of off road capability? When I started modding my truck, I told myself that I would be uncompromising when it came to offroad capability and assumed at one point it would cease to be a daily driver. I assumed when it came to tire size, bigger is generally better. My truck gets put through its paces every week. I've had my Icon rear monotubes replaced/rebuilt twice(next time around I'll get the CDCV 2.5s). Had the front ET coilovers rebuilt after I shattered the heim joint(it literally fell to the floor in pieces after being taken apart), added the LCAs after I wore out the bushings after 50,000 miles and I am currently setup to accept a secondary shock. Front sway is coming off with the secondary. I plan on going all out: cbi rear, arb lockers front and back, gobi up top with a couple of light bars, re gear after all of the additional weight, sliders, skids, ET remote resi's front and back, secondary shock, upper and lower links, bump stops. I even plan on ripping out the 3rd row and the back seats so I can shed the weight and sleep in the back because I don't want to add the additional weight to the roof.

The only question I really need answered is this: Will my 4Runner be a more capable offroad vehicle with 35 inch tires vs my current 33s? If the answer is yes, then thats what I am going to do.

If you are willing to do all that: yes! :girl:

I'm stopped up on my build because I think the most logical thing for me to do on mine is finish Lt front and cut and roll like [MENTION=49845]marshall[/MENTION]. However, portal axles keep entering my mind because maybe I could keep 34" tires and still gain the clearance...

The answer is yes. Do it.

 

[wfo9]

The answer is yes. Do it.

It won't be more capable if you are rubbing hard.. Which I think you will be with 35s. ~34.0 is the absolute max without MAJOR modifications. And they are still not easy to fit. BMC + rear bump stop extensions is pretty much mandatory. I had a tad of rubbing on the plastics my last time out in difficult terrain with the 34s, but I think I can resolve it.

 

[marshal]

The point is it's not that much harder to fit 35s over 285s for the street. It's pretty easy in fact. To make it work Offroad though, as you can see - it's an expensive and time consuming endeavor

 

[4Running Daily]

You should skip 35's and just run 37's
