Hey Dan,
Great thread and thanks for all the info. I have two quick questions I hope you can answer for me. Previously you wrote 235/40R17's would fit on a 17x7.5 with an ET of 45 and that the offset was pretty important. Do you think an offset of 42 is too little for that set up? And what make/model of tire is mounted in the first picture you posted?
Thanks,
Lou

225/40r18
The R56 has larger plastic over-fender pieces than the R53, and seems to have a bit more tire room as a result. We've previously fitted 235/40R17 on 17x7.5 +45 wheels with no interference...

We also put 225/35R18 on 18x8 +45 wheels:

Those were all-seasons, and it was time to fit some summer tires. I had noticed some downsides to the 225/35R18s. They have very little sidewall -- 225 * .35 = 79mm = 3.1" of sidewall. Plus the 8" wheels were substantially larger than the tire, meaning the edge of the rims were taking a beating from road grit and pebbles, not to mention a curb.
Since the 235/40R17 fits fine, I knew the 235/35R18 would fit fine. But there are only about three offerings in that size, and the cheapest is almost $200 a tire. On the other hand, there was a 245/35R18 in the new Kumho XS, and it was about $30 less per tire. I had wanted to give the Kumho a try anyway -- it's their newest high-performance summer compound. I figured if they didn't work out I could sell the set to one of my Subaru customers.
So we ordered them and mounted them up.

The good news:
- They have a slightly taller sidewall, at 3.4", so potholes are a little less of a problem.
- They protect the wheel lip much better.
- The grip is ridiculous.
- People love the way the car looks. Strangers stop me and compliment me on it.
The bad news:
- Of course, they don't really fit.
When we fitted the front wheels up, the inside sidewall of the tire was directly on the strut. So we fitted up a 5mm spacer (with longer bolts) to make some room.
Driving around with just me in the car, the tires don't rub under most conditions, but severe suspension compression causes rubbing of plastic on the tire. It seems to be mostly the felty fender liner and a little of the plastic over-fender that's making contact.
With a full load of three kids and their stuff in the car, it rolls fine on flat level pavement, but on any kind of bump it rubs a lot more.
So far it doesn't appear to be hitting anything structural. I'm going to keep my eye out for any actual tire wear. It's a hassle to change tires again, plus I don't really want to shell out the extra $120 for the 10mm narrower size, so for now I'm going to keep them on. But if you're thinking about doing it, I'd strongly suggest the 235/35R18 as a better fit. They should clear everywhere, and they probably won't need wheel spacers in front. That's what I'd go with if I were to do it all again.
Edit: To answer the questions of a couple of people, the car is lowered on our Mach V Technic springs. Stock shocks; H&R rear sway bar.

Any rubbing issues ¿

Which suspension? OEM or dropped and how much.
Compared with 18x8 et45 and 225/35-18
Your wheel and tire should be about 16mm taller tire diameter, and be 5mm further from inner suspension and poke out 5mm more. Overall this could work with OEM suspension for R56 MINI.

My stock wheels are: r17 7j et48
My new wheels are: r18 8j et40
And I want to run with 225/40/r18, but I'am afraid of rubbing) Maybe I can make another camber for my new wheels and tires?

What about a 17x8, +32offset with 245/40r17s. Pilot 4s?
