Land Cruiser Tire Upgrades?

[Markarian421]

it looks like the K03 your installing for a spare is 33.2 inches in diameter. I wanted to install 5 Mickey Thompsons Baja Boss’s that measure 33.4. That’s not looking good for me. Might have to switch to a different tire that measures at 33 inch max. Really wanted to do all 5 if I have a flat and can do the rotation.

Someone in one of the Facebook groups said their Toyo Open Country A/T III LT285/70R18's fit in the spare location, those are spec'd at 33.7". Either his spare is really aired down or some of these measurements are off.

I haven't crawled underneath to get a really good look yet, but I feel like my SL 265/70r18 Falken A/T4W barely even fits in the spare location.

Does my spare droop too low? (stock size A/T4W)

I don't have pictures or measurements from before I replaced the tires with the Wildpeak A/T4W in stock size SL load (265/70r18). But this tire droop is catching my eye as "is that supposed to be so low?" I didn't get under for a close look, but it does look like it's in the side bracket...

I saw that post, it's worth noting that it was not a US LC, so it's possible there's more room under there for non-hybrid models. ¯\(ツ)/¯

I wasn't a fan until I finally did the research to determine there's no con to this application other than possibly losing the hub centric rings on tire rotations.

OK, and what about aluminium rings ?? ... do you have any experiences ?

If you mount and secure the lugs correctly each time, the hub bore myth is non existent

Ok, I will try this then ....

Any pics to check poke with 33x12.5 R18 tire, or 305/65 R18 on 18x9 ET= +25mm ??

Many thanks ....

I put a Mickey Thompson Baja Legend 275/70/18 -33.4 in the spare with no problem. Psi at 38. Was originally at 36 but took my car to Toyota because I couldn’t get the TPMS to reset and change to a higher PSI setting for the new tires. Toyota technician said he wouldn’t run those tires at 36 and they should be at around 40 PSI.

Thanks for the reply, the Legend and the Boss’s have the same outer diameter at the 33.4. Mines in the 20 inch wheel configuration but the diameter should be the same. Thanks

Did airing down the spare help the fitment?

That's interesting, you're not the first to put these on and say they just barely fit in the spare location. I'm wondering if they are running larger than the official specs say? What PSI do you have in them?

There's no substitute for just crawling underneath and getting a look, and now that I'm finally home I can. The issue does not appear to be that it "doesn't fit" (so that's 0 for 2 on tire shop opinions), it's that per TW's observation here, it's just a pretty wide tire and is hanging lower than the factory 245 was. That's a different issue and one we may just need to live with.

Nice! Hadn’t seen that, but looking for 20” wheel and tire specs personally

@solidbrix weighed his 20" wheels for us and got 40 lbs. See: Sold / Gone - OEM 20-Inch Wheels (5x Pair)

Your... Bad Ass Tires... Do they make a difference?

Well... this guys says... Maybe but only about a 10% difference... ???

For a few years I had a Subaru instead of a Toyota truck/suv. I rented a lot of 4WD SUVs in that time -- a couple XTerras, a few Jeeps, a couple Hummer H3s, for light offroading in Utah and Nevada mostly. We got flats in nearly every standard tire those came with. Getting tired of changing tires and finding a tire shop in the middle of a vacation was much of what got me to replace the Subaru with an FJ, so I could go back to BFG AT T/As and Duratracs. For the kind of off-roading we do, I've never had a complete flat on those heavy duty off-road tires. I've had slow leaks but always repairable. YMMV and I may be lucky, but from my experience it makes a huge different in how often you get flats!

Edit to say he makes much the same point in the video. All terrain tires for toughness. That's why I have them.

Yea... I'm not sure buying bigger tires will help you with flats... unless your dealing with side wall tears... so how does this relate to my link?? I'm not sure what your saying???

He's not talking about tire size. He's talking about standard light truck tires vs. all terrain and mud terrain. Get an all terrain tire if you want a more indestructible tire you can take off-road without destroying it. Get a mud terrain tire if you want to go rock crawling. Stick with standard light truck tires if you don't off-road.

Saw that.. much heavier than I expected!

I don't ever use aluminum - Always plastic (Method sells them)

he's categorically wrong about 2 core points:

1-He contradicts himself. A front diff locker can be dangerous because its also a Steering Locker, you can't turn with it locked. Having an on-board computer locking/unlocking things automatically; dialed by Toyota engineers is more than adequate for the majority of situations. diminishing the Need for a "front" locker.

But, Brake Traction Control/A-TRAC moves power around after the tires has broken loose, rocking the truck and flinging dirt and rocks around. Locked diff's works before loss of traction occurs. so on a rocky or tight passages you need the smooth modulation of power across the axle to dial just enough to, say, climb over the front face of a big rock. Another situation is when the ECU bogs things down when you need power. That's just a couple of examples off the top of my head. Hence, YES, there are some situations/trails, where the better approach is to use them locker(s) instead of relying on brake vectoring. Smooth application of engine power is why we have CRAWL control on top of A-TRAC; nonetheless for their most extreme versions of 300, Toyota opted for all the tools for different situations. its not about people being "Stupid".

2-The blanket statement of AT's are 10% better in off-road than all-seasons is baseless at best. whatever he imparted is wrong on so many levels I honestly don't know where to start. Every tire is different, Baja Boss is an AT but also the Yokohama G015 is an "AT".
Whilst the the sidewall strength is a real thing, I'd rather listen to the opinion of reviewers who have real-world wheel-time offroading different tires than some snobbish rant.

Hi,
With stock suspension ??

Stock!

 

[Jean Louis]

Stock!

OK thanks ...

 

[shwazz714]

Check those ... 17" or 18", and above all: 95.1mm hub bore which fits with Land Cruiser 250 series .... and then let them be painted same color of your LC ....

Funny I was looking at the charcoal ones, think I may end up going that route just need to decide on tires.

 

[nvrlose54]

I went with a 275/70/18 Toyo RT trail. May do a level in a year or so, let the new wear off
