Predictions: Bigger Tires?

[on the rocks]

Sneak peek of Westcott's build on 37s.

No trimming..... just a removal of a few crash guards. Good job putting thought into this Toyota. It would be interesting to see how if performs.

EDIT* Either this guy is way short or this thing sits way up there!

Interested in if it rubs full stuff, full lock.

We have fitted 35x11.5r18 on a plus 40 icon wheel with stock suspension and no rub lock to lock, full stuff with very minimal trimming. A 37” tire will not fit without trimming in a real world situation without limiting up travel with some extended bumps. Simply lifting a vehicle doesn’t allow big tires unless you limit your up travel in the process. I am not opposed to a slight limit in up travel to fit bigger tires but my rule of thumb is if I’m going to limit my up travel I like to double the amount of whatever I limit it in additional down travel. I also don’t believe the 3.5” of lift as mentioned in the video above is possible without completely eliminating any down travel. In short, the one in the video looks awesome but it is not practical and will not perform well if at all to any real offroad use. I guess some have a very different definition of fit than we do

@benc

What’s your thoughts on a 285/75r17 (34”)? Do you think that would fit with same offset wheel without any trimming or removal of the front crush brackets or what ever they are.

I think they would but can’t say with 100% certainty. If it is a brand that runs small like bfg I would say most likely.

The start of my build. Coming from a 200 series. First step was wheels and tires. I removed the air dampers on the front fascia and the front mud flaps but not sure it was 100% necessary. No lift or any further modifications. After a 30 mile trip, no noticeable road noise and lost about 1.5mpg.

Icon Alloy Recon SLX 18x9 +40 offset
Falken Wildpeak AT4W: load range C, 285/70/r18 33.7 or Falken claims 34”

I took it over into the desert by my house and tried to get some rub but never felt or heard anything. Here are some quick photos I grabbed but I would say, success!

Are you adjusting your math for a larger tire when doing your MPG calculations?
I have not done the math, but from what I remember, you will do something like 3% RPM less with this tire (I looked it up once - I don’t usually have this sort of nerd knowledge in my head).
Might not totally make up for the difference you are seeing, but it would certainly contribute

Take 100 times (1 minus (original tire diameter divided by the new tire diameter)), and that's the percentage of how much less your speedometer/odometer is reading. it's not always 3%; it varies depending on the tire sizes stated above.

I put 275/65-18 Mickey Thompson ATs on mine before it left the dealer.

Listed as 32x11 on their site and measured on the truck they are 31.6” tall

They look good and should not mess with the power or gearing at all.

GPS is an easy way to tell.

My 200 with 34’s (really 33” mounted) speedometer is still dead nuts accurate.

No idea how or why but it is.

I went from 265/60R18 to 285/70R17 or 30.5 to 32.8 on my 460 and it's only off by about 5%. I still hit 6th gear since the tires are only 50 lbs

Not too concerned with a small decrease in mpg. I’ve oversized tires on two 4runners in the past and currently. I’ve still yet to find 100% confirmation that 285/70r18’s in an AT (Wildpeak) will fit comfortably on the LC 250 stock wheels and no lift. 275’s yes but anybody do 285’s on the stock setup?

I saw an lc250 in Scottsdale last night on stock wheels with 285/70r18 Toyo AT3, I was shocked that this worked but I also couldn’t tell if he was running spacers.

 

[Fort9378]

There've been multiple reports of 285/70R18 fitting stock. I can't recall any specific to Falkens but I'll post here if I see any.

 

[Hiluxforever]

Should fit with an alignment, there is so much more room than a J150, coupled with a reduced scrub radius

I've seen reports that they fit and don't rub turning, but no confirmation that they don't rub at full flex w/swaybar disconnected. On that flex test video things got pretty tight with the stock 265's at full flex.

These are the size being discussed and no rub lock to lock.

Nevermind. I see the desire now for stock wheels. I don't think I've seen 285s on stock wheels yet.

Double tap. Delete

This something about the LC 250 body that makes those large tires look disproportional to the vehicle as a whole. I and others have use the term cartoonish but I have yet to see a better adjective.

Thanks - that’s good to know. I didn’t mean that it was ALWAYS 3%, I meant that my memory tells me it was roughly 3% in between the tire sizes specifically being discussed.
