I have 18" JCW R105s on my JCW Clubman. I'd like to get rid of the RF tires and am trying to determine what tires will fit without rubbing. The offset of the R105 is ET52.

Currently the car sits stock but I would like to lower it at some point in the future about .5"-.7".

I'm running a 5mm spacer on the front wheels in order for the R105s to clear the JCW Brembo calipers.

Based on some searching it looks like answers all over the board so I'm looking for real time experience with these tires sizes and offsets.

TIRE SIZE - 215/40
The tires I'd like to get are the Hankook V12 however they ONLY come in the 215/40. Based on some reading it looks as though I might have rubbing issues. Can someone confirm?

TIRE SIZE - 205/40 (STOCK)
I have two choices, one of which is the stock RF. I'd prefer not to go this route.

TIRE SIZE - 225/35
Tirerack offered this as a size but I'm a bit concerned about rubbing due to width versus height. The Hankook also doesn't come in this size so I'm struggling with finding something comparable. Tirerack offers the Kumho Ecsta LE Sport but there is limited information available.

Any input appreciated.

Here is a little info but it might not help because it is on my 2006 R53 instead of a Clubman. I believe the Clubman has a little more room in the wheel well.

I had 215/40-18 Hankook V12s on 7x18 et52 wheels with JCW suspension so lowered about 5/8". The inside of the rear tire was close to rubbing on the suspension but did not rub. There was about 1/4"-3/8" clearance on the inside. No issue on the rear outside. No issue on the front.

I now have 15mm spaces front and rear so equivalent to 37 offset (52-15). I have 215/40-18 Hankook V12s on 7x17 et52 wheels with JCW suspension (lowered about 5/8"). The rear tires rub on the wheel arch and plastic inner wheel well when the suspension is loaded. I trimmed the plastic and now no rubbing. No issue on the inside. No issues in the front.

The 225/35 has a slightly smaller diameter than the 215/40 so I agree the height should not be an issue.

Since you are thinking of putting a 225 on a 7" wheel the actual tire width will not be much more than the 215 so my guess is that the rear inside clearance will be OK.

 

A 225 on a 7" wheel seems really large to me but that's what Tirerack suggested.

 

I just talked to Tirerack again and got a conflicting answer saying don't go with 225.

My options are guess are the 215/35 (less sidewall than stock), 205/40 (stock), or 215/40 (slightly taller).

I'd prefer the 215/40 but don't want to purchase until I can confirm from others they won't rub.

I had Hankook 215/40R18 installed today. Love them and they fit great.

 

Glad everything worked out well.
If you decide to lower the car you should be good (no rubbing) with the 215/40-18.

 

What a nice advise!
I am about to get a brand new set of black R105 with OEM run flats (also new)... I am planning to ditch the RF set and refinish the black in to body color (white silver) for next season and get the non-RF. Getting a bit "beefed up" tire size was my idea also... I am glad that 215/40 works good on Clubman.

Another good info. Is a 5mm spacer on the front for BBK Brembo.... For quite some time I was trying to find out what is the size of spacer required to properly fit R105 on Brembo. Finally, somebody has this. I will get Brembos in a few years when time comes for OEM brakes to be redone. Now, my next question is do I need longer bolts for 5mm spacers or OEM length is fine?
Thanks Sandreskog!

 

Depends on the Brembo kit that you purchase. I believe Sanderskog (original poster) is using the 5mm spacer to clear the optional JCW brakes made by Brembo. If you obtain an aftermarket Brembo kit the size of spacer will depend on the caliper size.

For example, with my Wilwood 13" and FSL calipers I had to go with 15mm spacers to clear the calipers with 52 offset Ronal R107 (GP) wheels.

 

I would go with OEM Brembo Kit, just as Sanderskog...

 

+1 on the OEM Brembo kit. That is a really nice kit but a little expensive.

 

The 215/40 works quite well. I also plan to pick up some coilovers soon and lower it about .7" and level it out (lowering the front more than back).

The 5mm spacer leaves you with about 1.5-2mm of clearance on the Brembo calipers (factory JCW). I opted to buy longer bolts. Some don't but I am not sure why you wouldn't as it's cheap insurance. One thing I didn't think of is if you have wheel locks you will need longer ones as well.

For clearance issues, yet keeping up with the big brake look and function, you could run the alternate DP6 caliper on the TCE/Wilwood 13" kit. Drops the required spoke clearance by 13mm over the FSL making it one of the lowest profile options on the market.

Granted; geared more towards the street enthusiast than the hard core track user due to it's thinner pads. But it does offer some stellar looks.
