White Trash Lexus got 37's

[Walking Eagle]

update - 5 - 29

Finally have been off-road a couple times. 1st time I was so preoccupied with just gett'n there I didn't even bother dropping the tire pressure - which was still at 60psi from being mounted - to say they didn't flex would be an understatement. But didn't wheel hard at all so it didn't much matter. Yesterday I dropped them down to 20psi. Still high for some, but without the safety bead I"m not 100% how far I'm willing to go. Got a little bulge out of them at that pressure, and they road pretty soft over the rocky bumpy areas where it's hard to make time without rattling your brain.

Zero complaints on rock crawling with them. They grabbed really well. Zero complaints on dirt, and even mud was very good, excellent if you consider how tame a tread this really is. Loose rock ledge up hill was a bit of a challenge (sorry, no photos of that one), but I can't say my MTZ's would have done much better - really anything short of a TSL or Bogger wouldn't have crawled those rocks, just required a little spinning into the right possition, so no real issues there.

I'm in less than $400 (counting shipping, new rims, selling old, mounting ect) for a set of tires that have almost 100% tread - so I am totally happy.

Looks great man! So with the stock gears and your new 37s, you don't notice a huge power difference driving?!

Also, this safety bead mentioned in your thread is the first place I've seen that. Is that something found on wheels or tires? and at first I thought from what yall said it wasn't ok to air down without one but now I see it is ok to air down without one but not too low? is that right?


oh and you got me green with envy... i just got a used set of tires, so am riding 305/70

Yes, I do notice a difference, but I'm stuck right now with the way it is. It's managable, and I don't drive it a whole lot - it's a daily driver, but only when it's not nice enough to ride the bike or I have to pick up kids.

The safety bead is on the wheels. It's basically a little ridge on the wheel. You have the outher part of the wheel, then the tire, then a little bump. It keeps the tire from coming in too far and loosing the seal. The lack of one is something unique to 16.5" rims/tires. There are some rare chevy 16.5's that have the safety bead. Airing down is always a matter tires, rims, truck as to what you can get away with, but generally, 16.5 w/o safety bead needs the highest pressure (say 15-20psi), your normal 15, 16, 17's so can run lower, if you have single bead locks you can go lower, double bead locks don't require much of any air. There are ways of making the 16.5's better, I've seen humps welded on, or the bead screwed on, or weld on bead locks, (though that only takes care of one side) ect. I'm o.k. with 20psi for now.

Walking Eagle - What is the width and back spacing of your 16.5 wheels? I have a similar lift as what you have and just got 5 95% tread Goodyear MTs like yours. I would rather have the recentered H1 beadlock wheels, but they are too pricey for me right now. I found a couple choices on 4wheelparts.com in my bolt pattern but wasn't sure what back spacing to run. Do your tires rub?

As I said before

U.S. Wheel 70-6860 - U.S. Wheel 70 Series White 8-Spoke Wheels - Overview - SummitRacing.com

so 8.25" and 4.75" backspacing - but I have 1.25" wheel spacers on so it's more like 3.5"

I went back and forth between those and the Procomp ones that are a 4" BS. These are rated at 2200 lbs vs. 2,000 and at the time a bit cheaper. Based on some other people's experiences I thought 3.5" would be best, and since 3.5" wasn't available, I just added up to it with spacers I already had.


As far as do they rub -

Front I didn't think rubbed real bad till I got it into a ditch where I could force the front to flex. I had forward progress stopped by the DS front hitting. But the DS front fender was all mangled anyway. I solved the problem this way

work starts at post 30.


The rear rubs a little on the PS rear outer lip and the bumper that was custom fitted for the 35's that were on it previously. If the panhard was centered I think I could make this go away.


My truck is NOT TYPICAL though - even in the world of non-typical modded 80's no-one will claim it as typical

Things that make it unique fit wise

1. Drop brackets for radius arms rather than other caster options
2. J springs w/ 1-3/8" spacer in front and no bumpstop extension.
3. J springs in rear with 2.5" bumpstop extension
4. 14 " travel shocks on all 4 corners
5. 1" body lift



The brackets obviously move the ending point for the axle, as does the lack of bumpstop extension beyond the coil spacers. The body lift moves the relation of opening to wheel and catches it at a different part of the arc. The long travel shocks get more axle angle than your typical L shocks or even some of the 10" Bosche alternatives. When on 35's, one side rubbed more than the other on the inside of the fender and frame in the rear due to the panhard, but it got worse with the longer shocks cause when I max out the rear, I'm really putting that tucked tire at an angle.

So with all that, all I can say is if you set it up exactly the way I do, you may or may not have rubbing I know the orange metal tech truck has 37's and he cut his fenders, he's 'low' on J's and no body lift. I know alot of folks on 37's have trimmed. Might hit Nay up see if his is cut, it looks stock.
