Gregory is correct. Toyota Lugs will eradicate the potential problem. Assuming your new wheels are the flat "Mag style" flush mount and not the acorn shape, you want Toyota Lug nuts 12 x1.5.

 

The other issue is when a multi Hex socket is used you'll run into major issues

 

Yep, dreaded 12 point spin. 2nd running the Toyota ones.

 

There is absolutely nothing wrong with the OEM Jaguar lug nuts and they 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 ft.lbs.

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 to remove.

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

Although I bought a set of Toyota lug nuts and related tools, I haven't changed them out yet because my OEM lug nuts are still good.

And that's the problem Stuart. Most guys on this forum rely on those lugs in the shop to do it right and no one wants to stand over them and tell them how to do it right. If you have a competent mechanic, you're good. Why stress out over it and risk having to cut them off one day and damage a wheel when $20 solves the problem forever?

 

At the end of the day it doesn't matter how they stripped, only that they will strip which means the covering shell was a poor design choice.

 

I agree for the US market because metric isn't the standard, but what about the rest of the world? Do they have the same problem with stripped outer shells? If not, then maybe it wasn't a poor design choice.

Why did Jaguar engineers choose the more expensive 2-piece design instead of a solid lug nut? What are the advantages that made it worth the additional cost? Longevity? Or planned obsolescence so they could sell more replacement lug nuts? Anyone know?

 

 

 

In 36 years of car driving/ownership I have NEVER 'dropped mine off at the shop' and left when any work tyres or brakes are required, I always wait.

I also always have insisted that the nuts are removed and tightened by hand, only if I am throwing the nuts away (due to corrosion or else changing to a different colourway of wheels) will I let them use impact/airtools to removed. So my take on this is it's actually the owners fault for not being more specific/demanding.

So no stripped/seized nuts from this owner to date

 

If only everyone had time to wait for car repairs. Sometimes the car has been in the shop waiting for parts. I guess I should just bring a sleeping bag with me?

 

I have few hobbies apart from my cars, also benefited from having worked my way up the ranks, to 8 weeks paid leave plus public holidays. In 35yrs of working I've only had to work a dozen weekends (when auditors were due in on the next).

I appreciate stateside, unless your self employed, you don't even get half of that, also that weekend working is normal, so you guys may have less free time to play with.

As they say don't blame the player blame the game

 

Yes Her, they will fit. The pitch is correct (12) and the length is correct 1 1/2 inches. As long as your current lugs are flat against the rim (Mag style) you are good to go.

 

Yes, they'll fit but how will you put them on and get them off? Your OEM Jaguar breaker bar fits the 19mm OEM Jaguar lug nuts but It won't fit those larger Toyota lug nuts. You'll need to buy a Toyota breaker bar or other socket and handle to fit.

If you had read the link in my post #6, above, you would have already known the answer to your question. And where to buy the new tools you'll need.
