BP51 OME largest possible tire (1 Viewer)

[MRego]

What is your goal? Just to look cool with big fat tires? You won’t be able to go on off road trails that you could with smaller tires. Because your wheel wells will have no room for articulation. So you will look like someone who just takes his Land Cruiser on pavement. But if that is what you want, so be it.

I am not sure if the question was directed at me, but in my case the goal is to actually go off-road and for that I would like to get additional ground clearance. I know, I know. Lift kits don’t get you additional ground clearance since your diff still hangs. However they allow you to fit taller tires. Here is my point. I currently run ko2 285 65 18s with OEM spacers. I went on an overland/off-road trip to Sedona and chickened at doing Broken arrow because of ground clearance concerns. Did some other trails and the car didn’t skip a beat and was amazing, but on ground clearance I honestly would say that I barely made it in some spots.

My plan is to fit either 285 75 18s or 295 70 18s to gain additional inches.

Couple things that may not be true for the 200-series relative to previous solid axle architectures.

1) Lift does not in itself allow fitment of larger tires. On an IFS rig, lift does not generally change the extents of the suspension stroke, like it did for solid axles. It only changes the neutral height of the suspension. When off-roading, said larger tire still needs to fit and clear throughout the travel, compression, and at full stuff. Therefore BP51s does not really create more room to fit larger tires. It may rub less going down the highway but is that the goal?

2) The 200-series allows fitment of pretty dang large tires. Rather easy to fit 34s on the LC, and 35s on the LX. Both can be taken beyond that too, but requires more work. Unlike solid axles of yore, controlled by less sophisticated suspensions, the double wishbone front and 5-link rear is pretty accurate and can locate larger tires without the need for excessive clearances.

Agree @MRego - larger tires are singularly the only way to get that diff higher up off the ground. With so many big tired rigs out there digging out holes and ruts, like warfare one-upmanship, 35s really are the new 33s out there to keep diffs from dragging.

Honestly, I would love saving money and not having to put a lift to fit bigger tires, but I do not believe it is possible to go bigger than 285 65 18 or 275 70 18 in stock form (by stock I mean using Toyota OEM coil spacers). Maybe I missed something in the other threads. Also, having the lift will help to clear some boulders when they are not directly heading to the diff lock. You know...when you go over a boulder with your tires and pray that it won't hit the running boards or sliders.

Totally get your point. Lift is a part of the modification path to a more capable vehicle. I encourage it.

Just that it's an independent decision from tire size.

The LXs share the shame chassis, suspension arms, and geometry. With the adjustable height AHC suspension, I can run the same normal heights with my 35x12.5s without any "lift". Or put the suspension down 2" in low and things still clear. Of course, I've sensor lifted it since. Just saying both those tire sizes you quoted can be run with no lift, but of course that wouldn't be as fun.

You mean 285 75 18s or 295 70 18s can be run with no lift? I do not believe so, at least in LCs.

It maybe answered by asking a question. Would those same tires need to have clearance for compression travel?

Sure thing. Not even compression travel. I may be wrong, but I do not believe these sizes would clear in normal driving in a stock LC.

Maybe we're talking past each other and maybe the lift point is moot as most will lift anyways. Besides lift, there's some key clearance mods that for the larger of those sizes. The smaller ones can and will drop right when configured properly with the right wheel offset. Some other minor things can be the plastic fender liner.

Thanks. Lots to digest here and I am not even sure I am capable of, since I have no engineering or mechanics background. My take is that a mild lift is better for articulation than an over-the-top 3, 4 inch lift. Along the way it might also help to clear bigger tires.

I have BP 51 and current 285/70/17 tire on OEM rims with 30mm spacers. I ordered Sparco Dakar 17x8.5J ET 25 rims and new 315/70/17 tires... Hope to be good

Late to the thread here, but are you still running 295's? I'm using bp-51 lift, Slee bumper, 1.25" spacers, and 60mm ET HE wheels. I'm at 28mm offset with the combo. Any fitting issues with yours with the KDSS arm?
