For my 2008 GX470 with 196k miles
The original rims, and pretty much every used set I see, are in bad shape from corrosion.
The offset of the originals are +25. I found a great deal on some good condition 4Runner rims, but the offset is +30, and too close for comfort. I mounted my non winter tires on them already.
So my question is, with good 5mm wheel spacers, that will bring the tire to factory offset, at this small size should it cause any trouble if installed correctly? The only thing I could think that would be trouble, is losing 5mm worth of threads.
Thanks!
If I follow, that will actually restore the stock geometry, more or less. With a small spacer like that I doubt you’ll have major problems. (You can always install longer studs for more security if you expect hard use.)
Yes it should be sitting just like the stock rim. Thanks!
positive offset means the wheels sit outboard. If you add spacers, you are putting them out even further, the opposite of what you want. No spacer can bring these wheels to factory offset. However, 5mm is pretty small. They might work fine. Just make sure you can turn your steering lock to lock without touching with suspension comressed. Make sure you wont be slinging mud and rocks all up the side of your car. Make sure your lug nuts catch a good amount of thread . Make sure the bolt pattern matches and the bore size is the same. These are the wheel basics.
@imperator Thanks for the advice!
I just double checked on the way the offset works, because the offset always sounds backwards to me. As best I can tell, With a +25 or 30 offset, the lug nuts go on the very outside, street facing side of the tire. Positive pushed the tire inside, as best I can tell, and from looking at my rims. For instance, my matrix rims have a +38 offset, and the tires go way inside when mounting them, a spacer would then push the rim out, away from the caliper and control arm etc.
If it was at 0 offset, the place where the lugs nuts go would be in the very center of the tire, instead they are on the outside, pushing the tire in when you mount it. Was that confusing enough? 😆
I think you're right. I was thinking of "backspacing" which is the complete opposite.
Offset is the distance between mounting surface and wheel center-line. In that case, yes a 5mm spacer would bring the 4Runner wheel back to center. This should work fine providing two things: the new wheel isn't too wide, and the the lug nuts have enough purchase.
I have a friend who put some bigy shiny wheels on his Tacoma with factory studs and nuts, and one came off on the highway in a curve. Months later on a trip, the bearings fell apart and stranded us in the middle of nowhere in the Rockies in subzero temps. We were lucky to get home that night.
