toyota 6 lug wheels on 1997 isuzu rodeo: pop.

Postby jakethacker » Sat Feb 18, 2017 9:46 pm

I just bought some nice toyota wheels with BF Goodrich Rugged Trail A/T's with about 70% tread left; $425. Checked the specs before buying them, everything seemed to check out, only concern was slightly different tire size (245/75r16 to 265/70r16). Got the first wheel on, set the lugs, lowered it off the jack and heard a pop. Put the thing back up and the damn thing was loose again. Tried it again, made sure the damn lugs were set tight (but not torqued down); let the truck down, go to torque it and the lug went loose again. Sketched me out, so I called it a night. Has anyone else had this issue, or are Toyota wheels strictly a no-no for Isuzu? If so, looks like I will be making a CraigsList post...

I am running Toyota wheels with no issues. Make sure you are using the correct lug nuts. Many of the Toyota wheels are hub centric and use mag lug nuts not the tapered acorn lug nuts like our Isuzu's.

I am thinking the toyota lugs may have been the problem. I was really hoping to use them though, since my Rodeo ones are a little stripped. Oh well, lugs are minor compared to the wheels. Thanks for the reply, I will give the old lugs a try tomorrow.

I mean to use the Toyota (mag) lug nuts not the Isuzu (acorn) ones. Do the lug nuts thread on okay? Verify they are the same thread pitch and diameter and make sure the studs aren't stripped out.

Toyota & Isuzu both use the same size & pitch M12x1.5 lugs. If the Toyota wheels are hub centric the required hub size to center the wheel on the hub may not be the same as the Isuzu hub. If that's the case you must use the tapered seat lug nuts to make the wheels lug centric provided the wheels themselves can be used with tapered lugs.
The stock wheels on my '03 Tacoma are hub centric but use tapered seat lugs, yours may be different.

Late to this, but yes, I was using the toyota mag lug nuts. Could they perhaps not be the correct length?

Yes, the lugs can be too short if they are the closed end or "acorn" type. When I went from alloy to steel wheels the ends of the nuts from the alloy wheels bottomed on the end of the lugs before they clamped the wheel to the hub: the alloy wheels were thicker than the steel. New longer nuts fixed the problem. To test thread a nut on without a wheel, if the nut tightens against the hub it will clamp the wheel before the end bottoms against the lug.
Is the centering recess in the wheel exactly the same size as the centering protrusion on the hub? You cannot use the flat end mag-style lug nuts unless the wheels center on the hub, you must use either the tapered seat type lug nuts to center the wheel on the lugs or an adapter to make the hub-centric wheels usable on a lug-centric hub if the wheels have a flat lug nut seat that prevents the use of the tapered seat lug nuts.

So I got the wheels on...turns out I was an idiot and did not realize the wheel recess on the Toyota wheels had more room than the stock Rodeo wheels (which fit flush on the hub), so the lugs were not actually going all the way on.

One of you may have answered this above, but is that extra space going to be an issue? Both lugs are acorn style with a washer.

Here are the stock wheels:

Here are the Toyota wheels up close:

This is what I mean by extra space - the wheel is hanging on the bolts, whereas the stock Rodeo wheels rested mostly on the hub (hub vs. lug centric?). The wheel became centered around the hub once I got the lugs ALL the way into the lug nut openings. So this is my point of contention, is this a safety issue?:

Thats how the FJ Cruiser wheels I use sit. I just line two lugs up by hand to get the wheel centered, put the rest on and then torque them down. Never had a problem with using the Isuzu lug nuts. Driven tens of thousands of miles on and off road like that.

I did the same. Its not ideal because the bore of the wheel should center on the hub and the nuts only clamp down. There are hammer in rings made from very hard plastic that you can buy that will solve the issue. They came with the wheels I bought from tirerack.com. I would order up a set of them when you get a chance. It will make the wheels safer to use and easier to mount. You will have to measure your desired ID and OD to order.

There ya go. I would not get the alumimum ones. Thats just asking for a galvanic reaction. Stick with the plastic.

Anyone know off the top of their heads what the OD and ID we'd need for Toyota wheels to Isuzu hubs?

I tried to look it up online but couldn't get solid numbers. You're probably better off measuring yourself.

An inexpensive vernier caliper would be accurate enough for that measurement.

pretty sure the bore on the standard Isuzu wheels is 101mm, with the lugs being 6 on 139.7 but they are not hub-centric so you may need something with a smaller ID than 101mm to get a good fit
