I've heard if you over tighten it can mess up you brakes. How tight should I tighten my wheels?

 

you heard wrong. tighten them til you can't tighten them anymore by hand. if you're using air, tighten them til the gun stops.

 

Huh? It's like 80-85 foot pounds.

 

I have a gun that you wont ever stop, it will spin away with a snapped off stud in your socket.

85 lb/ft

and yes it can warp your rotors by over torquing. You heard right

 

80 lb-ft, and thats from the helm manual so thats the "official" spec.

 

It's 80-85, you may or may not need to adapt a few ft lbs for aftermarket wheels.

Yes lugs can be over torqued.

I'm a bit of a retentive man when it comes to this and I will not use a gun it's hand then torque wrench.

 

I use a 3/8" impact gun at the lowest setting just to snug them. then the trusty torque wrench at 80lb-ft

 

they should be tight, (80-85 ft/lbs ^), but i dont think i would say till you cant do it anymore by hand. if you're using a 1/2" ratchet then that might be about right. if you're using a 4-way however you could very well break off one of the studs. also, not all air guns are the same. setting the impact gun to its highest setting might not be advisable.

 

is that for softer material or what? or is that just what those manufactures recommend?

 

I use whatever. Sometimes a 3/8 socketwrench, sometimes a 1/2 impact. It's not like I sit there and hammer it down on the impact, only takes a split second or so.

But I never tighten mine too much, there's no reason to. I hate taking others off that are torqued down like crazy. Never had a problem w/ mine comming lose from the cheapest lug nuts available, to expensive ones, from stock steelies to aftermarket aluminum wheels.

People tent to over torque things thinking that it's going to fall off if they don't. It's like hearing about people snapping or stripping bolts/threads on their valve covers when they can be tightened down with your fingers basically. I personally use a screwdriver w/ 10mm socket on it to do mine just so i never do that ;x

 

^ w3rd. you can overtighten your lugnuts, but you gotta be a real "musle man". with the right tools you dont have to worry. use an eletric impact and let it max for a couple seconds. really, its not that big of a deal when using good tools.

or if youre tightening lug nuts with a torque wrench, just use standard specs. its kind of a simple theory..

 

To be honest I'm not sure but I've seen a few cars that aftermarket wheels ask for a few more ft lbs.

I've heard a few theories but I'll read up and try to figure it out.

 

Cross tighten them.

 

Cross tightening or star pattern should be assumed.. least I hope

 

SLAP! your dumb
yeah thats the spec most people go by. Honda does about 100 ft lbs. Gray torque stick
seen it MANY times. it sucks!
yup. lol if people have rotas then yes, they NEED to me over torqued haha

 

over torqued why?

I torque both my SW388s and Slips to the same 85 ft lbs.

 

^It was a joke lol I dont like rota's very much. When I was in high school 2 years ago every kid and their moms had rotas. I thought the 17's and 18's where annoying till this stage. lol

 

Oh.

I had hoped you'd be able to solve the mystery of why some aftermarket wheels request a different torquing.

 

well the torque value depends on the stud and nuts strength mainly. but when the wheel is a different material (IE Aluminum) it tends to need less as when the rotor heats up the heat passes into the wheel. heat will soften the rim meaning you can actually warp the wheel if the studs are too tight. I know there is more info on this than my $.02 worth

 

That's what I assumed but a few cars I've had the aftermarket rims made sure to note using MORE ft lbs then OEM.

That's what I'm rather perplexed about.

 

hmmm...i never really see MORE than OEM. maybe its so the weakling thiefs out there cant steal the rims?

 

LMFAO

 

lol

I know that Blox extended studs need less from what I remember. Not sure if its just cause they are POS studs and break fast, or something else

 

tighten till it bottoms out then 4-6 hits after that

 

wow i would never let you work on my car the spec is 80ftlb ii hope you never use a 500ftlb gun

some manufactures recommend cheking the tourque after 20 miles on aluminom wheels
