Too tight will not cause a flat tyre. I am 65 yrs old and all my working life and still I do mechanical work.but by reading on the computer their is studs being stripped and Broken all over the world. I tell the tyre shops to not tighten by those bloody air guns, as these young guys think they know everything. But they over tighten every time, I have had to use a long bar to remove the nuts or studs. But they think they do not. But if you need a 4 foot bar to undo, it sure is over tightened. In my day that never happened if done up by hand, it is dangerous and what person could take off a wheel if they had a puncture. But tell them and no one dies it. Dick heads,but dangerous, as over tighten and the metal crystallise and breaks. No matter how cleaver they think they are but it should've a law not to do up with those bloody guns.

Hello

First of all NO that would not cause a flat tyre

Secondly every time I have had work done at a garage or tyre shop they have always used an air gun.

I carry an extendable lug wrench for this very reason

If you studied physics and chemistry, this would be easier.

That was the dissimilar metals having a electrochemical reaction and the two corroding between.

It is not that the clamping load of the nut was that excessive,

But the fusing reaction of the two kinds of metal in contact, then presence of moisture. Then time and temperature extremes.

But look who you listen to ! Letting the tow truck driver give you your cause for an automobile diagnosis??????

That's like asking the gravedigger for advice on why your illness has new symptoms.

When MEN were putting tires on, we used a little white grease as an oxygen blocker for dissimilar metals.

Get your flat diagnosed, who knows? It could be proper helpful preparation can save a bead leak from happenning.

You can pay for extra labor? or you can take it home and do it yourself. The kids arent paid for what is needed in labor,

the conglomerate is making the tire money.

Your leak could cause the tire to be run low, The drivers inability to sense a low tire allowed it to continue.

Encountering an off road terrain can then push the tire off it's bead seal. Or what ever it runs against or runs into.

One thing is certain, shifting blame by all parties is always a waste of time, for their long term credibility. A Road hazard tire policy is available at time of sale.

Please train the new kids. phasers on stun, Scott out.

Absolutely not! Jack the car up inflate the tire and spray the tire tread with 50% Dish soap and 50% water. You will easily find whar ever is causing the leak.

No but it can damage the studs.

Make sure you watch them put your wheels on and do not let them just use an air gun. They should be done with a torque wrench.

it wouldn't affect the tire cause it's the rim that gets contact with the lug bolts/nuts

your not changing a tire , your having your wheel changed, over-tightening wheel lug nuts can occur the lugs/studs from breaking off causing the wheel to come adrift. lug nuts should always be torqued up to the vehicles specification.
