This is an absolutely massive platform, so you'll see quite a bit of variety when it comes to fitment, but this will give you a good idea of what wheel sizes and offsets are safest for your platform.

Ford Focus ST/RS 18-Inch Wheels

To start things off, we're breaking down a 2018 Focus RS build running 18-inch wheels and lowering springs

 

Build Breakdown: 2018 Ford Focus RS

Wheels: Enkei NT03M 18x9.5 +40mm

Tires: Firestone Firehawk Indy 500 265/35

Suspension: Whiteline Lowering Springs

Since this is a wide setup, you're going to have a little poke without having too much of an aggressive stance.

This setup is super easy to achieve because it doesn't have any rubbing/clearance issues, and the owner didn't have to make any fender modifications, which is a huge plus.

If you were looking to get a flush fitment with 18-inch wheels on your Ford Focus ST/RS, most people run 18x8.5 with a +35mm offset wrapped with 235/40 or 235/45 tires. 

Overall, this is a super solid setup that fits the wheel well nicely without any modifications or rubbing issues.

You could go up to 245/40 tire and still get a flush fitment if you like the look of a bigger tire. It's not a massive difference, but enough to notice. 

With this setup, you'll have a little less clearance in your wheel well, but most, if not all, people running this setup in the gallery don't have any rubbing issues (on coilovers or lowering springs). 

 

CHECK OUT SUSPENSION FOR YOUR FOCUS ST/RS

Now, if you're going to run air suspension on your Focus ST/RS with an 18-inch wheel, you'll lean more on a tucked fitment style, so when you air out, your wheels fit perfectly inside your fenders. 

Most Focus ST's/RS's are running a wider 18-inch wheel to get some stretchy bois, but there's plenty running the standard 18x8.5 still.

Ford Focus ST/RS 19-Inch Wheels

Bumping it up a lil to a bigger setup, we're breaking down this 2017 Ford Focus RS running 19-inch wheels. 

A 19-inch wheel on the Focus ST/RS fills up the wheel well a little better than an 18-inch wheel does, but you'll end up running a tire with a smaller aspect ratio/sidewall height due to that. 

 

Build Breakdown: 2017 Ford Focus RS

Wheels: Rotiform KB1 19x8.5 +42mm

Tires: Federal 595 RS-RR  235/35

Suspension: PRO-KIT Performance Springs

The most common 19-inch wheel setup is a 19x8.5 +42mm, but offsets range between +35mm and +45mm for this specific wheel size. 

This Focus runs these exact wheel specs and has a nearly flush fitment, which most people are going for (nearly flush/flush). 

Since the wheel width is pretty modest on this Focus, no trimming was necessary to make this fit, and there are no rubbing issues.

A 19x8.5 +45mm with a 235/35 tire seems to be the sweet spot for a perfectly flush setup. 

Again, no rubbing issues or trimming are required here.

It's as easy as bolting them on and hitting the road! 

 

5 MOST POPULAR BUDGET TIRES

However, you'll want to take into consideration how low you are. 

If you're running lowering springs like the 2017 Ford Focus RS build breakdown, you shouldn't run into any fitment issues, but if you're slammed on your nutz on coilovers, you may need to opt for a smaller diameter wheel or raise 'er up a little bit for better clearance.

If you're currently running or want to run air suspension with 19-inch wheels instead of coils or lowering springs, most people are the same 19x8.5 wheel size with offets ranging from +35mm to +45mm. 

Remember, you'll want to have more of a tucked fitment so your wheels fit nicely inside the fender when you air out. 

 

ARE STRECHED TIRES SAFE?

Ford Focus ST/RS Final Thoughts

With such a huge platform like this, the fitment options are endless, but I hope this wheel fitment guide helped narrow it down for you. 

Depending on what type of build you're going for and what type of suspension you're running, you'll lean on a certain type of fitment (flush or tucked), so keep that in mind when you're checkin' out wheels.

Most popular 18-inch wheel setups:

- 18x8.5 +35mm to +45mm 

- 18x9.5 +20mm to +23mm
