I believe this is the correct size but don't know the specifics of your wheels and HL.
Thread size: m12 x 1.50
Hex size: 20 mm.
Happy with the Gorilla lugs I put on both my Toyota's.

 

Thanks. That helped alot.

 

I've been happy with these from DPaccessories. They're one piece construction rather than the capped like some of the OEM that can corrode and swell. They've been holding up very well for me and still look new even after a couple of years in the midwest with salt in the winter.

I like McGuard. Guaranteed not to rust

 

If the OEM nuts swell, what's the chances the aftermarket nuts above won't do the same thing?

 

I've sold wheels for 24 years (and the lug nuts with them). This isn't a problem. I've seen it happen about 3 times in all of those years.

 

I've seen it happen about 3 times in all of those years.

Of the three Toyota's I've owned (one of them a Lexus) the stock OEM lug nuts on the two with aluminum rims both had issues eventually. In both cases the lug nuts were the type where it was a chromed metal cap over the actual nut and the underside of the cap or the nut itself corroded and began to swell. Replacing with solid nuts that have a good quality coating (chrome in my case) is the obvious choice. Why Toyota choose this type of nut just makes me scratch my head and wonder why they chose to use that style in the first place.

 

I've seen swollen lug nuts on Fords and GM. Haven't seem them on any of the Asian vehicles we've owned, but I'm sure it could happen. There are stainless replacement nuts you can get. Those shouldn't swell.

 

I just got a tire rotation and balance done and was told that I needed new lug nuts because of swelling, I was surprised as I've never had such an issue before with any car. I'll be looking for new lug nuts now.

 

In my experience this happens when the impact wrench is used to tighten the nuts. Instead, spin them on with the impact but tighten with a torque wrench. Just another reason I do my own work.

 

why not just spin them on by finger, no need for impact to potentially damage!, the four (16) on my car is easy to finger on, the 24 (6 per wheel) on my truck takes a bit extra time to do that, time that the DT does not have apparently

i bot a box of 10 Doorman lugs from rockAuto (~$25) my truck takes weird mag lugs, dealer wants $8 each for Toyota black mags, that is almost $200 for a whole set new
tried powdercoating half of the original weathered lugs a couple of years ago, they looked great, but after nearly 10 rotations at DiscountTire (and their impact tools used) they are chipped and getting worse
i need to get some pics of those for reference...

i hope that these new doorman lugs do not swell up on me!

 

had the same issue on my 13.
just replaced all of them. i also went to HF and picked up a breaker bar and deep well impact socket that i leave in the car.
Makes road side repairs much easier for the wife and piece of mind for me.

 

i am possibly looking into getting some of these to protect new lugs from the impact wrenches used out there, and for personal use as needed
has anybody had experience with these type?

I’ve used those with good results, too. Plain Jane ones work,too. Just tighten with a torque wrench.

 

After 13 years the wheels on our ES350 corroded enough to have slow leaks. I replace them with some hyper black wheels with Aodhan neo chrome lug nuts. They looked cool...until the winter. 1 New England winter the coating was significantly corroded. After 2nd winter most of the coating has flaked off. At the recommendation of my local shop (and the internet), I just bought McGards to replace them. Can't review those yet, but if you live somewhere that has winter, stay away from the Aodhans.

FWIW the OEMs where in great shape, but I needed the cone style for the new wheels (and i lost the socket key for the locking lug on each wheel).

 

Thanks everybody for your feedback. I did purchase 24 DP Chrome lug nuts. That's the same kind that I had on my 2013 Avalon that was totaled. I did have some very slight rusting on the ones on the 2013, so I bought an extra four so that if I do have any more that rust slightly, I'll have replacements. I like them and they looked good, there was just some very-very minor rusting. I have not had a chance to put them on the 2018 yet, I am waiting for my audio guy to finish up with an upgrade. (A week and a half in a high-mileage '08 Camry loaner has me longing to get my car back!) With any luck he'll call today and I can pick it up tomorrow morning. Fingers crossed! I'll replace the lug nuts when I do my next oil change/tire rotation.

BTW, I too use a dedicated 6-point socket and a breaker bar. Hand-tighten and torque to spec.

 

I was looking at Gorilla lifetime's, I stumbled across gorilla automotive: 61138 , they are 12x1.5 with bulged Acorn shape. I would think that this should fit given the specifications.

Even though the specifications are fitting for a 3rd gen Highlander, the parts fitter said that it's incompatible(for sku: 61138 ). Anyone have a clue as to why(could be a mistake), anyone have experience with gorilla's on their 3rd gen Highlander, which part number/sku did you get?

Also, for a stock replacement, do we need the bulge or no bulge? Will either work?

edit: I see on Amazon's part fitter, these two Gorilla sku's are supported for my 2015: 91137B, and 41137B, however, neither are part of the "lifetime" series, which I'm trying to get... though for all of them they are 12x1.5... and seeing that they end in "B", I'm assuming that's for "Bulge".

 

I looked at each of the numbers you mention (61138, 91137B & 41137B). None of them are for OEM aluminum rims. Yes, the threads are right. Yes they may work with the steel rim spare. No, they would not be OK for the aluminum OEM rims. The stock rims have got to have the flat washer for securing the OEM hub-centric aluminum rim. The original nuts do have an angle at the tip (not a bulge), but that is for when the nuts are securing the steel spare. That angled tip is not in use when securing the OEM aluminum rim.

@ssnova, Do you have different rims on your 4th Gen?

Never mind, thought this was my lugnut thread on another forum when I saw the alert on a response. I'll "unfollow" this one so I don't make the same mistake again. Oops

 

@IE5QE0 thanks for the information, I'm assuming you were initially referring to Avalon's until you caught yourself and crossed out the info. None the less, it was still helpful, especially if it's still applicable to the Highlander to an extent.
