Sorry - complete newbie here.......

I ordered the 15" wheels and tires from GoWesty (they look sort of like
Mercedes wheels).

When putting on the new wheels should I use anti-sieze compounds?

Also, should I just torque them down as tight as I can or get a torque wrench?
Should I use a cheater pipe?

I ask this because many, many moons ago I changed a flat tire, tightened the
bolts, drove away and the wheel almost came off miles later, it was just held
on by one bolt when I got home, the others had eazed out! I thought I
tightened the bolts enough but I guess not.

Thanks........, Markus.
