POLL: What size tires are you running on your JCW?
#26
#31
On a 2010 S coupe w/ Challenge rims...
and factory sport suspension, running Michelin PS2 225/45-17's. (Posting figuring with an MCCS and the Challenge wheels it still will have the same clearance issues)
No rubbing at all--over 4,000 miles of use now. Tightest clearances are on inside front of tires when going to full lock (but still clears inner fender lining), and up near the inner top and inside edge of shock towers in front (clears fine but wouldn't be room for tire cable chains). Rear is all fine--seems tightest near inside side of tire rather than at fenders, but all fine.
Speedo error reduced by about 1/2 ; filled out fender wells somewhat more visually too. Very satisfied.
If you go 225's, look carefully at the sidewall width. Some listed in the detailed TireRack specs are 3/10's" or so wider in the sidewall area (where it bulges the widest) than others, even if the tread width is relatively constant and it is nominally the identical tire size. The Michelins (and a variety of others) were narrower in this dimension, but some were wider. Would have one to a 215 if I really wanted a given brand but the spec. had an above average sidewall width.

Here it is with the 235s. They do not rub.

This winter I've been running 215 x 45 x 17" with Michelin ICE tires. No problems. I had thought about going with the 205 x 50 x 17" but Alex at Tire Rack suggested that I not do this if I was thinking about lowering the car any. I'd like to go with either that, or the 225's, but with my luck, I'd have a suspension issue at the very least. Still have to do the Summer tires this year. Everytime that I think about that, we get another cold/icy snap.

No, much more simplistic--plus practical experience since...
I simply turned steering left to full lock and then right to full lock. It doesn't touch it the inner fender liner. I don't think doing that at any real speed or really loaded would make much practical sense--you wouldn't corner hard to the point of full lock and load up the suspension like that, short of some kind of street stunt driving anyway as far as I can think of.
As far as the struts, it's not that close where I think any suspension deflection is going to make a material difference. By eye and feel, I would call it about 1/2" plus from the tire to the spring perch lower edge when looked at for verticl clearance. That dimension can't change in any meaningful way regardless of suspension deflection. As far as the inner clearance--widest part of sidewall over to the lower part of the strut below the spring perch, I would call that about 3/8"--about the thickness of a man's index finger at the nail squeezed a bit to be specific how I approximated. It is no where chose to paper thin or even 1/8" or less or some such where it might be getting close. If I used the widest 225's in the sidewall or went up toward 235's or some such I would want to check more, but I don't feel it's near the ragged edge yet at 225/45 in the MIchelin PS2's.
And, the practical field test is about 4,000 miles now on the tires, with car filled up at times (4 people) and driven on highways, aggressive on ramp cornering, city streets and bumps, etc. No rubbing and no marks indicating the same anywhere inside the fenders or on the tires.

I’ve since installed coilovers and switched back to 17’s (215’s) and the ride is soooo much better.

205 /50 17 will fit on a stock 2010 JCW clubman.
Only a problem if vehicle is lowered? I have no intentions of lowering.

Veggi has a similar setup on his r53 with the 225 rcomp tires with non lowered suspension and they fit his car. I think you should be good to go.
