Not in all cases, depends on wheel offset and design. With 0 offset, chances are it will be fine but as you get into positive offsets, it’s not a guarantee that you’ll clear the caliper and the UCA.

Yeah but why would anyone want positive offset with a bigger wider tire? Counterproductive there.

Bigger and wider tires aren't just for a wider stance. If you can get a better driving or handling result with positive offset wheels, or fit a larger tire easier, or potentially other reasons not related to wanting a wider stance.

Ideally the centerline of the tire should roughly split the centerline of the wheel bearing. - that's generally how engineers design the hub/wheel assembly as a system for long life and good handling characteristics. An ideal widening of the stance would be the result of wider axles, not wheel spacers or wheel offsets. But we compromised because wider axles are expensive.

While I agree, that just generally doesn’t work with our configuration. Solid axle maybe, IFS not so much due to the uppers getting in the way.

There are positive offset wheels in 6x139.7 out there so in a forum where somebody may come looking for info, I think it’s a fair call-out.

love the wider stance. truck does feel more stable at speeds.
285/75r17. think i'm approximately 3" lift in front, -8mm offset wheels, and 32mm spacers. total -40mm offset.

bmc, hammered pinch welds. caster +3 or more. relocating my lca pivots 1" forward soon

Rayofsi, since you have a set up close to what I want I figured I’d ask you for your input.

I just bought my first 5th gen T4R ORP and I’m about to order some wheels for it but I’m stuck between 17x8.5 0 offset vs 17x8.5 -12 offset.

I have a set of some Falken Wildpeak AT3s coming in 285/70R17 and I have a kings 2.5 mid travel kit with SPC UCA in the house ready to be installed.

My question is if you think my SPC UCAs will afford me sufficient caster adjustment to avoid doing a BMC if I go with the -12 offset wheels?

If anyone else has accomplished this lmk. I’ll likely order tomorrow morning but I figured I’d ask haha.

Thanks.

Thanks for this post, as a new 4runner owner its nice to have as a reference.

many people run 285/70 without bmc. Fingers crossed. hah

I am new to posting and haven’t figured it all out yet. I appreciate the detailed introduction about tire fitment of the original posting.

I have a new 2020 Toyota 4Runner TRD Off Road Premium with KDSS. I had a 2002 SR5 until traded up for the 2020 model.


As I am very new to all this aftermarket modifications I have been reading a lot on this forum. I recently purchased upgraded undercarriage protection.

Now I want to lift my 2020 4Runner TRD off-road with KDSS. I would like a 2 to 3 inch suspension lift. I’m into functionality over bling bling. With the new lift, I would like to get at least 33 inch off road tires.


Do others have thoughts on using stock 4RUNNER fifth generation TRD off-road 17 x 8 factory wheels with 33 and possible 35 inch tires? The tire fitment guide earlier said it did not recommend going over 33 inches and I understand the reasoning now.

The standard TRD off-road wheels are about 8 inches wide versus 7.5 inches wide for the TRD pro model. They don’t look as cool as the TRD pro model, but are they more functional being 8 inches wide? They are a lot cheaper to pick up used as an extra set of rims to mount larger off for road tires on them. I would change out TRD off road rims with 33 inch aggressive tires for trips into the dirt and rocks.

If I’m going to use the rims for off roading and they’re going to get scratched up possibly why not use the less expensive TRD off-road rim model then the more expensive stock TRD pro or aftermarket rims?

I welcome any suggestions so I can help educate myself.

Thanks

Hi All,

Just as an FYI I recently fitted Cooper AT3 4S in 275/55 20 to my standard Limited wheels. Looks good, appropriate for winter and gravel roads and no rubbing.

That's all.

Did the same thing to my Limited as well (putting the 275/55 20 Coopers AT3 4s on), but did get some very slight rubbing, only in reverse when turning hard, nothing a heat gun and a little pushing couldn't fix though. Like these much better than the OEM Yoko's.

Might switch to 18s. Can’t find a decent tire that’s C load.

I don't know if this video has ever been shared, but it's a pretty good illustration of how a lift affects larger tire fitment and suspension travel on an IFS rig. It also addresses the realities of extended bump stops. Even if it's a Taco lol

That video makes it so clear, it should be required viewing before spending on any suspension upgrades.
