The Gorilla lug nuts ( #73138J) arrived and are installed without any issues. The photos show that the new nuts are slightly taller than the old so that they protrude a tad more that the old ones and display better on the wheel. I have the original lug nuts that appear to be in good nick ( probably could use a proper cleaning) and they are free to anyone who can use them by simply paying shipping. So far so good.




The 2 on the right are the new ones and the 3 on the left are the OEM.

 

You can use Toyota / Lexus wheel nuts as they are the same M12x1.5mm. The Toyota ones are slightly heavier but will not disintegrate and split.

 

I would love to get them from you.

I wouldn't use the OEM lug nuts, for cost saving reason TATA used substandard alloy for the nuts.

 

Absolutely untrue. The lugnuts are not made of alloy - you are referring perhaps to the lugnut *covers* - these are easily destroyed by ham-fisted "mechanics" who use an impact drill/air wrench on them, rendering them useless..
When a proper torque wrench is used on the OEM lugnuts, they are not damaged and will last the life of the car - decades. The lugnuts below are original on my 2001 XJR - they are in perfect condition because an air wrench has not been used on them (and one on the left is a locknut):



and the lugnuts on my 2015 F-Type - they are identical to those on the XJR, and also undamaged for the same reason:


But once damaged, the original lugnuts certainly can be replaced by the Gorilla or Toyota versions - on which an air wrench should also NOT be used.

 

A couple of my OEM lug nuts were damaged when I purchase my XKR but not as bad as these in the picture. I had to hammer a socket to remove a couple of the the lug nuts as they were mangled up and rounded. A 5 min job turn out to be an 1 hour job just to remove the wheels to repaint the calipers.

 

TATA didn't buy Jaguar until 2008, and the XKs were designed well before that. They had covered lug nuts from jump, so TATA can't claim that debacle.

 

There's nothing wrong with the OEM Jaguar lug nuts that a tire jockey armed with a power tool and wrong size socket can't fix.

The OEM Jaguar lug nuts will last forever without any problems IF you always use the correct size (19mm) deep socket and hand tools only, and use a torque wrench to tighten them to 92 lb-ft. I keep a 19mm deep socket wrench in my trunk together with the factory tool kit that includes a breaker bar, jack, 12 volt tire pump, and torque wrench. My XKR's lug nuts are still like new because I insist that tire jockeys use my 19mm socket and hand tools only.

Problems happen when tire jockeys who don't have metric sockets repeatedly use the closest size SAE socket that fits (usually 3/4") together with a power tool with excessive torque to remove and reinstall those lug nuts. That will eventually cause the outer shell of the OEM lug nut to deform and spin on the inner nut, thereby making it difficult, but not impossible, to remove. Simply hammer a 19mm or smaller socket onto the deformed lug nut to remove it.

Don't blame the OEM lug nuts. Blame the lug who used the wrong tools.

 

Stuart S, I actually used a 19mm nylon lug nut socket with a breaker bar to remove the OEM nuts without any drama and then reinstalled the new ones to 92 lb/ft. I did notice that as I removed the originals that they all felt as if they had been torqued to 50-60 lb/ft so that may attest to their overall good condition....good news bad news. The original lug nuts are currently awaiting shipment to wymjym in Texas by the way.

 

I certainly like the appearance of the Gorilla nuts as demonstrated by MoXKR. Also have to agree with analysis by Stuart S about tire jockeys using 3/4 inch socket and an impact wrench (rattle gun) to tear up the nuts. Probably the rims too!!

Coincidently, this morning I just purchased my first set of wheel sockets so that I can avoid the same Neanderthal treatment of my Jag's wheels.

 

I have experienced the frustrations with damaged wheel nuts too. Initially my car was missing one wheel nut. Not sure if it was missing when I purchased the car or if it departed soon after I owned it. I procured a replacement OEM nut and installed. Within the first year of ownership I twice discovered my wheel nuts damaged apparently from mechanics and procured more replacement nuts. I had observed that the nuts on my car required a 20mm socket but my new set of Craftsman wheel sockets didn't have a 20mm. Was even shopping for another set of wheel sockets that included a 20mm socket. Recently I discovered that some of my wheel nuts appeared to be 20mm while the new nuts are 19mm. Having wheel nuts that require two different size sockets might be a contributing factor to explain why mechanics are damaging the nuts. After reading the forum threads about alternative wheel nuts and verifying that the wrench in trunk with jack was in fact a 19mm I decided it was time to replace all of my wheel nuts with a set of twenty Gorilla 73138J that are 19mm!!
