Has anyone seen the new Axis Wheels? These look pretty awesome and they come staggered! 17x9 +10 and 17x10 +15. I think it's cool seeing a company do something for these older cars. Pics are from the Axis website.

 

Wow, those are nice....

I really like Axis Wheels. They look good on that Camaro. I was curious if it had any spacers or adapters. Too bad you still have to run 25mm on the front.

 

Unless Axis has changed their game, those should be the wrong bolt pattern, 5x120mm. Our cars are 5x4.75". If you have to run adapters anyway, then you could use adapters that adapt the bolt pattern as well.

you can run a 5x120mm rim on our cars, these are 5x120mm he is not using adaptors

 

Can and should are two very different things. You are eating away at your stud stress margin by bending the studs to meet the wheel.

 

its no more unsafe than spacers which seem to be extremely popular and so far no real problems.

 

Please explain your position.

Wheel studs (along with 99.99% of all other screws/bolts) are designed to be loaded only in tension. With a properly fitting wheel this is reality. All the stud and lug nut are doing is providing a clamping load to produce a frictional force in the transverse direction. The friction between the wheel surface and the rotor surface is what is taking the loads from driving.

By adding a spacer you really aren't changing the situation. As long as you still have enough threads for a safe connection and as long as your friction has not degraded, the situation is no less safe than stock.

However when you use the incorrect bolt pattern, that is where you are decreasing your safety. The wheel is not going to move. So as you tighten your lug nuts, the stud must bend to accommodate the wheel. The conical mounting surface of the lug nuts and wheel force this. So now you have your stud under tension and bending loads. The tension side of the bending stress now puts the stud in a higher stress than was intended when the torque spec was created. This may have now put your stress above the fatigue limit of the stud. On top of that the bending load is trying to open up valley of the thread. That valley is a great stress concentrator for a crack to grow.

Now cue the "well all these people on the forum do it with no issue, so it must be ok" response.

For a viable solution to the bolt pattern issue, see this thread.
