Who says you can't fit 34's!?

[itr1275]

Thanks and it makes senses.

I've seen the pinch weld thing as well.

 

[TRDHULK]

Wow! Looks good.
So at full lock in Reverse the tires don’t rub the front bumper?

Thank you!

It would have rubbed, but the Pro's are trimmed at the port, and I trimmed another 1/4" and already moved the liner forward.

I'll be wheeling it tomorrow and will trim as needed. I bet I end of taking off another 1/4" to a 1/2" off the bumper, just to play it safe. the BMC should not give me any problems though; I think I cut it enough. My RSG plates should be here next week so I can weld them up.

Great stance!! How's the ride quality with the Burtman spacers?

Its not bad. The larger tires actualy make the ride better than the stock Nittos with the spacer lift.

At slow speeds, I can feel that they are MT's. On The Highway, so far, I think the ride is great.

You'd be surprised, that's a big assumption. Lot of these builds are nothing more than 'gram builds. I'm willing to bet this thing isn't going to see more than a dirt hill. There's going to be plenty of rubbing if that suspension is flexed out but not sure that's going to be an issue here.



One of the lighter 34" MT (well 295/70/17) I've seen is the Cooper Evolution MT weighing about 59lbs. They're only 2 ply sidewall though so I'm guess that's where they shed some weight.

They come in pretty cheap too

I'm still riding on 285/70/17's and with all the weight I have I won't go with a bigger tire until I re-gear. She's right at the tipping point where it's still tolerable but I don't think it would drive well at all with a bigger tire.

I'm going to take good care of my 4Rnr, but it is in no way just a "gram build." I've already had it off road 4-5 times in the month I've owned it, and will be doing some more serious stuff this weekend, hopefully.


Isn't a 295/70 typically a 33.5"? These 285/75's are showing 34.1"


I can't find how much this tire weighs anywhere. They feel a little heavier, but honestly the extra weight kind of makes the truck feel more planted, and maybe more substantial. It only feels slightly more sluggish. I really don't think I'll regear unless I go 35's in the future.

BTW, what does a re-gear in these usually cost?

The Yokohama MT's weigh 63.3# per the Yokohama website. My same size Coopers are 65# in a AT as a reference.
A 285 /75/17 is by the exact metric measurements 33.83"x11.22". Your Yokohamas as with my Coopers are a bit taller at 34.1".
A 305/70/17 is also considered to be a 34" tire at 33.81"x12.01". They are considerably harder to fit due to the extra width.

I haven't checked re-gear costs since I re-geared my rig about 3 1/2 years ago, to give it a guess, using a pre-built clamshell from ECGS and average labor at a reputable shop I'd say $2500-$3000

Here's a link to some details on the re-gear. Search and you can find lots more info

Thanks for the info.

So it seems the Geolandar is fairly light for a 34" MT. More good news!

Aaaaaannd I'll be holding off on the re-gear at that price lol. This is just my daily driver that I'll have fun with whenever I can.

Update

Took her to my testing grounds at the back of my neighborhod to check clearances at full compression and articulation.

At full compression in the front, the tire is about 1/4" to 1/2" away from the body mount. I'm still able to cut a little more so I think I will just to be careful.

At full lock in reverse, with the wheel turned to the left, it slightly the front bumper rubbed. I've shaved about 1/2" off the bottom edge of the front bumper, and now there is no rubbing in any direction, even at full compression, even in reverse.

The rear is perfect. Close, but perfect; no rubbing at all.

 

[srsrogerissrs]

You'll need some UCAs next. Adding some caster will push the wheel forwards and give you more body mount clearance.

 

[LandCruiser]

If you don't plan on filling the gap of the BMC, at least trim the sharp corners.

Yes I'll be doing some JBA's in the future. I bought a lifetime alignment from my dealer so I can change my suspension al I want without paying for an alignment everytime.

You gotta read my friend! I've mentioned the only reason I haven't welded is the plates did not arrive yet.

I'll be rouding off the sharp corners, and I bought rounded RSG plates so weld on, so I'll probably gain aother 1/2" or more of clearance.

 

[stephan07]

Looking good! I has planned on the RSG after I did the BMC myself with an angle grinder in about 15". I got lazy, and never got around to it, and theres already a circular hole in the Body mount, so other than looks I just didnt get to it. Never see it.

Since it isn't really a structural point, I'm also in no hurry to weld.

I ordered Metal Tech plates initially, but I cut too much of my BM and the plates were too small. I really couldn't find any plates that I liked, until I found RSG, but I did not like the laser cut "RSG" script they had. Well, I found out you can order RSG plates from Toytec for $10 cheaper and they don't have the large "RSG" logo cut into them.

I've even considered cutting the entire tire side of the BM all the way to the frame to get even more clearance, but thats a lot of work.

I've been skimming threads trying to get a good understanding, but I'm just asking here directly hoping for a knowledgeable answer. And no offense to OP, but I'd like to hear from someone who has done this and put it to the test off road.

Is there any work besides trimming the bumper/fender liner and a BMC that's necessary to run 285/75/17 tires?

I've seen references to hammering a pinch weld, but without pictures I have no idea what that entails.

I don't have any issues with cutting up my bumper more than it is. And I've resigned myself to the fact that a BMC will need to happen. I just want to know what I'm in for in addition to that... no surprises on my first trail ride after installing. I had a passing conversation with someone at Slee Offroad when I was buying an air compressor, and he seemed to think that 285/75/17 would entail a lot of additional effort.

I know, I know, a bunch of you have 34's and even bigger already, but I'm excited about them and it wasn't the end of the world to make them fit!

Those are some sexy tires. I plan on getting the same ones but no clue what size to go with.

I can read, I've just seen what sharp metal does to tires. I'm not convinced you're not going to rub and that edge is like a knife right now.

No offense taken, but are people thinking since this is a pretty green Pro that I haven't taken it off road? I realize I haven't done major rock crawling, but I took it through some pretty rough stuff yesterday before I posed it up on some boulders for pics. I articulated it as much as possible and rubbed my arm and hands all around the tires and wheel wells searching for areas that might need massaging or cutting and could find any, other than the sharp corner of the BM that I will be cutting when I weld the RSG plates on.

Also, keep in mind that most 285/75's are not true 34" tires, but more like 33.8 or so; about 1/4" smaller than these MT's. A K02 would fit even better than the tires that I chose.

You can also go with a 295/70 which is usually about 33.4-33.5" which gives you a very similar look.

Thank you! You could play it safe and do the same tire in a 285/70 or even smaller and you should be fine with minimal clearancing.

No worries :thumb3:

That sharp edge will be about 1/2" to 3/4" further away after next week. That picture was at full articulation with the wheel turned.

Hey listen we all believe you. However you've been on 34's what a week? Give it some time. Load it up and see what happens then report back.

Re-gearing. First thing I would do, after installed 34” tires,before any wheeling. Just to keep my drive line and transmission happy.

looks good. keep the spacers. it doesn't rub just run it and enjoy!

Thanks for the feedback, I appreciate it. And I really wasn't trying to exclude your opinion, just wanted some input from someone who's been running this setup for a while. As someone else above me said, there are other situations that may cause issues that you haven't been through yet.

I've been told thats over $3k. I can find much better things to spend $3k on. I have 2 project cars that'll get that kind of attention.

Plus I dont want my RPM's at 4k on the highway.

looks good. keep the spacers. it doesn't rub just run it and enjoy!

:thanks:
