Hello,

I have a 2006 Lexus LX470 with stock rated tires, they're 275/60 R18 Michelin defenders, I have added a 1.5" wheel spacers, have taken it off-road a couple of times (mountain drive), however I am looking to install off-road capable/rated tires, the truck still has a fully functional AHC and I am not willing to delete it, any recommendations on what tires and tire sizes fit nicely and look good on the truck? I was thinking of installing 285/65 R18, but will need your help deciding please, it's much appreciated!

On OE Lexus wheels, without spacers, I had no issues with BFG KO2s in 285/65R18 and later in 275/70R18 (while still running AHC).

Aftermarket wheels (with different offset) and/or spacers may alter what will/won’t fit.

Thanks much! Yes, I’m planning to keep the stock wheels, only replace the tires and also keep AHC

I went with 255/85/16 and prefer those to the wider tires. They don’t sit flush with the outside of the fender, but are fantastic size for the utility. You don’t have a ton of options for tires, but I have had good experiences on previous vehicles with the st maxx.

Remove the spacers and you should be totally safe with 275/70/18. With spacers you might have to do some pinch weld/liner reshaping and washer reservoir removal. Either way the spacers limit tire size before rub occurs.

Larger tire > Spacers. :p

@Monstertruck I just went with what @bamabrock posted from the 100-series FAQ
Your post is a common question, common enough they made it a FAQ
2nd item under the 100 series basics = What is the largest tire I can fit with no lift? - https://forum.ih8mud.com/threads/what-is-the-largest-tire-i-can-fit-with-no-lift.263259/
I am running 285/65/18 Yokohama M/T
Be advised that any M/T or A/T E rated tire will be louder and a bit firmer than those really smooth Michelins, but you still got AHC...so that helps smooth things out a lot.
I also run 1 inch Bora spacers and am glad I did not get anything more than that (as @suprarx7nut pointed out = with spacers you may rub)
Hope this helps and welcome to the Forum

275/70R18 yields a taller LX.

285/65R18 yields a bulkier overall look on your LX.

Thank you all for this great feedback!

I do like my tires to sit flush with the outside of the fender (just for overall looks), so I think I will go with 285/65R18, I am hoping they won't rub with the current 1.5" spacers, otherwise I might need to change the configuration. My goal is to have a nice bulky/aggressive looking truck with added off-roading capabilities, I hope I am not asking for much :)

Anyone knows of any potential impacts of running spacers? I heard that spacers might reduce bearing life and/or negatively impact suspension components, any thoughts?

Thanks again for sharing your great experience and knowledge, this is really helpful and much appreciated :)

I think you'll be fine with 285/65/18. That's 32.6" and even with the spacers I think you'll have some clearance. You can check by turning the wheel slightly and then get out and look at the clearance between your current tire and the liner. If you have at least 1" of gap you should be fine. Your potential new size is about 1.6" larger overall, or about .8" larger on each side.

Spacers: if installed properly no huge issue, but it's not doing any favors. It creates a larger lever arm on the suspension and bearings, but none of those items are fragile on the 100. It's made to be abused. Just be sure they're installed clean and fastened properly. If you search around you'll find catastrophic failures of spacers coming loose, but they tend to be A) off brand spacers and B) people can't confirm they were installed properly. Take them seriously and you should be fine.

I will confirm the gap between current tire and liner before ordering new tires, thanks for the tip! :)
Also, what is the recommended tire pressure for the 285/65R18? I think it won't be the same as my current tire pressure, correct?
I like BFG KO2's, but wondering if KM3 is a better bet... in my case I don't think I'll be doing super hardcore off-roading, and would like to get the quietest possible off-road tires...
I also understand that my MPG will take a good hit, I currently average 10.5-11 city and ~15.5-16 highway, does anyone have an idea of how big of a hit in MPG with 285/65R18?

Thank you!!!

Pressure wont be much different due to size. I run 35 ish on my 295/70/17 ridge grappler.

KM3 are definitely not the quietest off road tire, haha. I love the look, but I couldn't stand driving a worn MT for long on the highway.

Mpg hit depends on your driving, but doesn't have to be huge.
