So how much torque do Tyre dealerships use?

[iDestiny Junior Member Find all posts View Profile Close iDestiny]

I replaced my OEM tyres with MT STZ today. New tyres were nice, but the process left me wondering...

They popped a rear wheel stud - ok no problem - "We used the recommended torque and sometimes this happens - but little unusual in a new car" they said (I have only done 6K).

Then at handover, the guys walks up to me again and says "you should have a little chat with Toyota about the torque that can be used on the studs, from our experience they seem way too low"...

So I asked what they used - "130 83 ft lb" he said (At the time, i didn't know what the recommended was). When i cam home and checked the manual it says 76 ft•lbf (they were >70% over recommended wheel nut torque)

So I am thinking, it is a small surprise only 1 popped?

Perhaps, I need to get the remaining studs looked at?

Or am i over thinking this?

Thanks

What is 130 83 ft lb? It doesn't make sense.

I'm not sure I follow. Is it the tyre fitter who you say is using the wrong torque, or the toyota dealership mechanic?

Who is "they" when you refer to "they" were >70% over the recommended wheel nut torque....tyre fitter or the toyota dealer mechanic?

and I'm not sure what you mean by "130 83 ft lb" ?




isnt 83ft lbs closer to 113 Nm?

From what I remember 110 Nm is about right??? Perhaps?

Apologies tyre fitter used 130 ft lb... (he didn't say Nm) Manual says 76 ft lb (I Shouldn't really type this stuff while trying to give a 7 year old a bath and feed a 5 year old at thew same time)

If he said 110 Nm, then it should be about right, but he definitely said ft.lb

Where was this? The two places I use both torque to spec with torque wrenches. A pain with the GTS which is crazy high.

I made this mistake, my mechanic mate told me to use 110Nm. I like a good numpty used 110 ft pounds. You need to check and set your torque trench properly.... Needless to say I popped a wheel stud. I ended up replacing them all on the two front wheels.

It's a place called NOELS PROGRESS ROAD PITSTOP (Wacol, QLD)

What worries me is that he said "We usually use 130 ft, but these don't feel like they can handle more than 110"

So either he meant Nm but said ft.lb. If I assume that is true, i need to query Toyota regarding why a 'professional tyre fitter' thinks it doesn't "feel right" (i.e. at 110 the wheel studs feel like breaking, as opposed to their normal 130).

OR


He really did mean ft.lb and now "they don't feel right" because the wheel studs are just about to pop!

Either way, I get the feeling I might have to make a visit to the dealership.

Did i also mention they initially said they were trying to "source an original toyota wheel stud" as the 'generics' they had didn't fit (new model). Then they mysteriously found one that did fit...

(wishing I wasn't as mechanically challenged now :/)

I had some silly tyre tyre fitters stretch my studs, he said we only used 125ft pd, I educated them.
Most tyre shops I ask use 100nm.

I'd be pissed if they did my new vehicle at 130 something. Twits!

At each service I write on the contract that all wheel nuts including spare are to be hand torqued to spec.

Having been caught out in the middle of nowhere many years ago and unable to get the nuts off I make it perfectly clear that if I get stranded again they will be held responsible for all recovery costs and consequential damages.

And then I check them myself when I get home because I still don't trust them.

And to add insult to injury I found one was cross threaded after the last service. Can't imagine how that happens if you put them on by hand.

Problem is they don't generally put on by hand. They just hold the nut over the thread whack the gun on and hit the trigger. I tell them not to use the rattle gun, if they can't do by hand I'll take my business else where. I've been stuck before because they tighten to their spec of FT. I've also had threads stripped before.

Truth be told, I hadn't put much thought into this subject (or cared about how tyres are changed) until yesterday. 20 years of driving (19.5 of them on the bitumen in cars), only had 2 flats ... never had trouble changing those. Guess, just like everything else, helps to know how the world works (admittedly only had done about 40-50K/year, and tyres were rotated regularly)

Glad I bought a Prado and glad I found this sight!

The GTS requires 190Nm so I carry a breaker bar and impact socket. The factory tool is rubbish and I bent it badly, then went to the dealer and destroyed two more as a demo but that is another story. A mate with a wee Suzuki rang me on his way home from work one afternoon. He had a flat and couldn't loosen the wheel nuts. No problems, headed off to meet him and the factory Suzuki tool had no show either. Not because it was rubbish but the dealer had tightened the nuts with a rattle gun. Checked the manual and the wheel nut torque was something like 100Nm. So I went around the lot with the breaker bar and loosened them and redid them with the factory tool.

#2 forgot to tighten one of the Colorado wheels after a service, loose nuts are bad too. He was very lucky that when the studs sheared the brake drum fell into the wheel.
