so you got the tires yet....
had 33 under mine and a 34 would have easily fit...might have rubbed a little on sway bar but will fit up under their fine. Now it is on BIOR bumper so no more worries...
actually may removed the cross brace in addition to just the lowering mechanism so when I re-route my exhaust I can take it up into the well for better clearance with some heat shielding up on floor of cargo area underneath to keep it from making that area too warm.

Damn I hate to ask this (fearing replies RE: SEARCH! 'cause I did... honest officer - lots of "shoulds", "maybes" and "I thinks") but, having just swapped to 275/70/18s, I'm wondering about the need to match the spare. So the question that surely has been asked... If I flat, can I use a 275/60/18 spare to get me home with NO damage?
edited as per below:
Yes you can runn different size tyres but dont DO NOT DO IT WITH ANY OF YOUR DIFFS LOCKED UP, by locking any off your diffs with odd diamiter tyres you are forcing one wheel to turn more than the other. This is ok on slippery surfaces but even on any grip surface you can overwind the diff, and you are putting huge strain on the transfer case that may damage something
Over wind is also know as "axle wind up" where the front and rear wheels (or the right and left) are rotating at different speeds, with the diff locked.
If the rolling diameter differs only very slightly it would be unnoticable on say sand or dirt roads as there is enought slip on the road to keep the wheels going reletivey the same. But engaging 4WD on a any grip surface (or with big grippy 315 KM2's) and your just asking for something to snap.
Hope that is a bit better.
(Also consider when you would be likley to need your spare tyre? If your on a trail "getting home" is a whole other story....) plan for the worst and hope for the best.

Before anyone throws tomatoes at me --- I've looked at the FAQ and searched but haven't found a definitive answer yet.
For upgrading my 2006 LX470 tires I'm currently trying to decide between:
I know that the 275s will fit in the stock spare carrier location without incident. Has anyone been able to squeeze a 285 or 295 equivalent in there while still retaining the hitch? My rig has a popular aftermarket hitch receiver that I've seen on quite a few rigs on the forums, so I suspect this is a common use case.
I'd like to fit the largest option out of this set that I can. Thanks in advance for any guidance you can share!

The largest tire without noise issue and less inaccurate speedometer that will fit under spare tire carrier without removal of tow hitch and it won't rub in fender wells while turning is 285/60/18.
I have them installed on my 06 LX and I am very happy with them.

If you have the in-bumper hitch behind your bumper cover and it meets your needs, you can remove the standard hitch and fit a larger spare.
Agree that's a great size without any worries. I'm trying to go a bit bigger and don't mind doing light mods to make it happen -- slight trimming, AHC sensor height mod for lift, spacers, etc -- I just don't want to compromise on using the stock spare carrier. Not looking to deal with carrying a spare on a swing gate, roof basket or elsewhere -- been there done that
Thanks, will look into it -- admittedly the Cruiser came with the aftermarket hitch assembly installed when I bought the vehicle from a fellow Mudder, but I was told at the time that the OEM in-bumper hitch solution had some limitations for attachments, spacing, and ratings with what you could hook up. Need to educate myself more on that...
