thank you

LOL, ya think?

& yeah wish I had a caliper this morning cuz I was trying to explain what part of the cone made contact with the wheel. you can see the contact area is the exact size as the new cone. (not in the 2 I pictured but 1 I had in my hand in the garage) the OEM bolts are actually bigger than necessary where the topish ring of the cone makes no contact with the wheel! but I wasn't going to change their minds. it's a good shop that always does their best. so whatevs ... more pissed at you-know-who for the poor design & customer service. even the guy at the Jeep parts counter was shaking his head at them & that they weren't covered by warranty

EDIT now that I look at these 2 pictured, it looks like the whole top wider part of the cone makes contact with the wheel, so maybe the after market ones are lacking a smidge. probably safe enough, but I can see why the tire shop took the "corporate" & safer route

That's correct.

However...

Look at the OEM bolt and how its lower cone doesn't make contact with the wheel, and how the top part of the cone inside the lug hole hasn't seen a bolt on it. It's a cone... and as I highlighted in a pic up there, there is more cone to work with below the contct surface made by the OEM bolt. So the new bolt will simply fit a tiny bit lower in the cone, getting roughly the same contact area (contact height) as OEM bolts, just a bit lower in the wheel. This is exactly what tuner bolts do...

But like you said, they freaked just because of how *small* they look compared to the oversized OEM bolt heads. And yeah whatever... at least they didn't try to get more money out of you, they just thought they were preventing a bad situation down the road.

The OEM bolts suck, and no matter how careful folks are with impact tools, they will get damaged, and some may require extreme extraction techniques...

That's brings up an interesting point : the use of torque bars on air guns. I went back and did some reading on wheel seats, bolts, nuts, etc... and one thing that popped up was : impact tools should never be used on alloy wheels. Period. In real life, only a very small minority of techs - and even DIYs - adhere to that rule. Alloy wheels are softer and they damage easy, especially around the lug nuts/bolts. They are sensitive to impacts and overtightening, especially.

When torque bars made their appearence on the market, the good ol' torque wrench was almost doomed, at least in shops. Especially during the hectic tire seasons (for those who live in climates where they use winter tires), shops are more worried about volume than being gentle on alloy wheels...

So put these together : impact tool + torque bar + capped bolts/nuts, and you get what you have in that pic up there... : a 2 year old wheel bolt good for the garbage...

That's what I'm worried about... I have the black alloy wheels and I'm going in for my first tire replacement soon. I'm deathly afraid that they're going to gouge my wheels with their stupid air tools. I've seen first hand that it takes very little to scuff those wheels!

If they use thin walled, nylon coated sockets... it's a good start. If they don't bang the socket onto lug bolts and are careful about torque, even better. But the odds are not in our favor...

I think the darker the wheel, the esaier it is to touch them up when scuffed. It's not ideal, but with black you'd need to look really close to tell...
