Aftermarket wheel offset help

[aznxfactor]

I figured that I would start a new thread to get some much needed help.

Would you happen to know what a good offset would be if I was to buy an aftermarket rim? Everyone pretty much put rock warrior, trd off road, or trd pro tundra rim 5x150. I think all of those are oem +60 offsets. I'm not too sure what the offsets mean for the lc200. I want to put aftermarket wheels but +60mm offsets are not in the market at all.

Basically if +60 offsets arent available for aftermarket, what would be an ok one that wouldn't ruin my axles, boots, etc. Biggest 18 I've seen on eBay is +40 while 0, 12, 18, and 20 are common. Please let me know.

FYI, the TRD Rock Warrior wheels are 17 x 8 with a +50mm offset.

So +47 offsets would be ok? How about +20mm?

 

[TeCKis300]

Simple answer is anywhere between 60mm and 20mm would be good, with optimal offset being closer to 60 than 20.

At 20mm, and depending on the tire size, the tire will just start poking past the fender and cause some handling and clearance issues when turning. Offset does affect the scrub radius geometry of the suspension so it's better to be at closer to stock offset range. It's a bit complicated and overall tire diameter does come into play, but for a 33" tire, optimal offset is ~40-50mm offset range.

It really depends on the tire size you want to run as well. Wider tires past 285 may require no higher than 50mm offset, such that it clears KDSS and suspension components.

Many here run +20 offset. Kreitin and a good number of others. You'll likely have to trim fender lining or remove/trim mudflaps, but no big deal.

Thank you so much! As this helps me to know what to look for in tires.

Just curious, if you're saying that tires wider than 285 may require no higher than +50mm, does that mean that tires 285/75/18 or 285/70/18 on oem rims wouldn't work? I have a 2016 land cruiser that is stock now. Wanted to put aftermarket wheels and tires.

Bro! This is what I've been looking for! You da man!

Thank you everyone!!!!

Thank @MScruiser ...as he actually put it together. Great resource...

I'm running XD Hoss 20x9 with +50mm offset. They fit great. I would recommend a higher offset (closer to 50 than 20) because you can always add wheels spacers but you can't go the other way. Wider tires may scrub! I have 35x12.50x20 BFG all terrains on mine with no scrubbing.

Like others have said don't just get hung up on the wheel offset, wheel width, tire size, whether or not you relocate your KDSS bar, are you going to use bigger bump stops, how much fender lining are you willing to cut etc, etc... So many variables to the equation. Take a gander at the tire and wheel chart @MScruiser made and that should get you a good idea of what will work and what might cause some rubbing or other issues... I run an 18x9 with a 20mm offset with 285/70 R18's and after trimming the inner fender linings don't rub at all. Welcome to the Gang!

When my BP-51 fronts arrive (still painfully waiting), the plan is to mount 17" XD128 Machete wheels with 0mm offset along with Toyo R/T 295/70/17. This was the recommended offset by the 4WheelParts salesman. I take 0mm offset to mean that they are 61 mm offset outward from the stock rims. Looking at the comments and @MScruiser's chart, it looks like that's really an outlier. I'm looking forward to a wide stance, and am not totally averse to some well done fender flares if needed, but I'm beginning to wonder.

On a related note, I'm also beginning to wonder if I should throw down this $ on my very clean 95K 08' LC, or should I just buy a newer used one before I embark? I think I know how most would answer, but was just wondering what others thought about it.

Expect to do some massive cutting... That will be quite a sweeping wheel turn at 0 offset. You are going to severely hit stuff.

Edit: See @gaijin 's response below for a more technical way of saying the same thing...complete with explanations and research.

Toyota has thoroughly tested the TRD 17 X 8 +50mm wheel with LT285/70R17 tires - no rubbing under any circumstances, 0 (zero) scrub radius, no alignment issues. That should be a baseline for comparison against any wheel/tire combination you might want to try.

I'm not saying you can't go wider or taller with your tire choice, but by comparing to the baseline wheel/tire setup, you should get a better idea how things will fit.

This is just one tool I use - I have set it up with the 17 X 8 +50mm TRD wheel and LT285/70R17 tire as the satndard on the left and your proposed 17 X 8.5 +0 wheel with LT295/70R17 tires as the proposed setup on the right: Rim & Tire Size Calculator. Custom Offsets

As you can see, this particular modeling tool shows that your wheel/tire combo would not even clear the fender. This model suggests that for that size tire on a 17" wheel, the recommended offest is +48.

I'm not advocating anything, just suggesting you might want to try something else. And, yes, a newer used 200 sounds like a good idea.

I had a similar conversation with @kreiten last summer

Kreiten Build thread!

Summary: If you're planning to lift, or even run front coil spacers, higher offset wheels with taller tires are an option. If you're not lifting then you're going to be severely limited, especially if you're thinking of stepping up the tire size. 275/70R18 on the stock +60 offset wheels is about the biggest you can run (and that's 10mm narrower than the stock width) based on feedback I've seen from @kreiten and @Romer. If you want to run lower offset (+0, +20, etc) without a lift then you need to watch the tire sizes closely or you risk slicing the tire on the fender or smashing the fender.

@Blake Loggins would you mind posting up a picture of your wheels/tires? I'm really curious about the width and stance of 12.50" tire.
I just picked up a set of BBS 20s (20x9, 50mm offset) and looking at either 295/65 r20 vs 35/12.50 r20.
I like the thinner tire size, but there are so many more options available in the 12.50 width.

thanks

No offense, but lift for tire fitment is a common misunderstanding from the solid axle days. In the way that most of our lifts are done for IFS, lift has almost no bearing to clearance. The tire will ultimately travel through the same stroke. Lift just changes the neutral point.

It bears repeating here from Slee so we don't keep persisting this confusion:

Lift does not provide more tire size clearance. It only changes the starting point where the suspension starts cycling from. There are some minor exceptions to this and that is when you use the adjustable UCA's and bottom eccentrics to move the wheel position forward or backswards in the wheelwell.

Does not matter if you cheat the AHC, if it is a Tacoma whatever Toyota IFS, when the wheel is compressed it is pretty much in the same spot for a lifted vs non lifted vehicle unless the lenght of the A-arms are changed, or bump stops changed.

As an observation from the KDSS thread, if you really want to run 12.5 width tires, it'd be worthwhile to look for wheels with slightly lower than 50mm offset to give clearance to the KDSS link. Something in the 40-45mm offset may be ideal.
