Sick winter steelies anyone???

So i know winter tires are a hot topic right now, but i want to get a set of Diamond Racing Steelies for my Cx3!
Ive always wanted a vehicle to put some on and i think they look awesome compared to the normal "Donut" steelies most tire shops sell.

Has anyone put more offset wheels on/better fitment wheels? Im probably going to get 16" as my GT came with 18" summers.
Does anyone have the proper measurements i would need to order some?(offset,bore,width)
Do you have photos? I would like to be able to lower the car with some Corksport Springs so i want something that will clear the fenders if i lower it as well.

Mazda OE wheels are either 16x6.5 or 18x8 both ET50. I can't find it stated anywhere but if the hubs are anything other than 67.1 mm, I'll eat my hat.

I wouldn't go crazy with offset if you're going to lower it unless you want to pull the plastic wheel arch cladding off or rub the fender liners.

I've seen TireRack guarantee fitment of 16x6.5 ET55 steelies. I ran 18x8 ET38 with some old 225/50-18 snow tires (leftover from my previous car, about 1.5% larger than stock) last winter and had minor rubbing on the fender liners at full steering lock.

If you're in the US (and possibly Canada) you can go to and/or, enter your year/make/model/trim and it will show you only what they know will fit. If you buy both wheels and tires from one of them they will mount/balance them for you before shipping.

As far as tire sizes, both 215/60-16 and 205/65-16 should work.

Try this wheel size tool. Just select the calculator icons and the export icon on the trim that shows the 18" tires as stock. Another window will open in which you can plug in different numbers and see the results.

NotAPreppie is right center bore is 67.1mm, the wheel manufacturer should provide you with the correct hub centric rings, just be sure to ask.

Now you just have precisely estimate how much you will lower the car.
