Just fitted some sweet alloys to me motor but not sure what torque settings to tighten them to and what pressures Can someone that has 18's on advise me please so I can try them safely.

I always worked on the assumption that it should not be so tight that you cannot undo them with the standard wrench. No doubt like mine this dont fit anymore with the new nuts so I bought a spider type wrench and follow the same strategy. I hate it when tyre places go mental with an air wrench and you cant undo the nuts again.

 

Less rambling and answer the q= 72-87 lbs ft or 98 - 118 nm stock.

 

Dont suppose it should be any diffo for other allys but you might need to double check.

 

You'll get a debate on tyre pressures though - I think a couple of psi up on stock is warranted with 18" wheels

Torque setting ought to be the same - it's the studs that take the torque, afterall..

 

My rule of thumb on pressures was start off at 2psi per 5% in profile drop, and then play around that point to even the tyre wear out, or to suit your driving style..
