Will 17x8.5 rim fit my r53

I have scoured the forums for info but only seem to come.up with mixed answers. I am looking at a set of 17x8.5 rims ( 45 offset) and come paired with 225/45 r17 tires.
. My r53 is stock height , stock brake calipers. From those with similar setup , did ur wheels clear everything well or will i run into issues?

thanks for.your time

Here's my uneducated guess: The wheels will be too big, and you'll get rubbing somewhere. Those tires are big.

IIRC you can but you have to modify the steering rack to have a "bump stop" in it to prevent rubbing by stopping the rack from being able to go to full lock. 8" is the absolute max and even then I think that there might be rubbing at full lock with 225 tires. 7.5" would be the easiest route with a set of super 200/endurance 200 treadwear tires like Potenza RE-71RS, Direzza ZIII or Azinis RT615+ in a 205 or 215 width. You might be able to pinch on a set of 225's but you will be pinching them on 7.5" wide rims.

Someone locally here in Portland, again, going from memory, did get 9" wide rims on their car but did put in rubber stops to keep the steering rack from going to full lock. The tires did rub the inside of the fender liner without the steering rack mod. I cannot remember if they needed to roll the fenders as well though. Rolling the fenders on these cars brings up a whole other set of issues due to the fender trim.

So, can you do it? Yes. But there are other modifications that you will probably need to do.

thank you for the detailed info. also thank tou for the rip on steering lock . Yes it seems 225 /45 tires will be too much . The reason I was trying to make it work is because they come as a package with a set of rims.i had my eye on .
. I was thinking perhaps even trying to fit the 17x8.5 rims (45 et) with a 215/40 tire , but looks like it will be pushing rim closer to suspension and I would need to run a spacer which would probably have me roll the fenders which i really dont want to .
. Also i think a 215 tire on a rim that wide may be stretched ?

I thought I could have made it work as I am on stock suspension , but never really took.into consideration the wider rim and full steering lock .

Not all 215's are equal.

A 215 on a 8.5" wheel would probably be stretched a little bit. The OEM tires for my Miata are 205/45-17. The Bridgestone S001's that came on the car had, according to Tire Rack, a tread width of 6.5". The no longer available in the size Michelin Pilot Sport Cup 2 (240) tires that I have on now have a tread width of 7.1". They are the same size tire at 205/45-17 on the factory 17x7 wheels. Somewhere Michelin measured the tire and they got 205mm. Now is that the exact same place where Bridgestone measures the tire? Maybe? I have no idea. Will the 215's rub? Maybe, maybe not. The brand and model would give a better read on rubbing and such. But I think that it will be stretched. I did some wandering about on TireRack and everything in the 215 size says that they are for 7"- 8" width wheels. I can go up to 215 on a 7" and some have put 225's on the stock wheels but they are pinched, not ideal but unless you are doing track days or autox not that big of a deal but the sidewalls are working more.

I can tell you just from looking at the tiers on the car - the Michelins are wider in nearly all aspects. The Bridgestones did not look stretched and the Michelins don't look pinched - but the Michelins do look wider. My wife commented on them after I brought the car back from getting them mounted with - "Those tires look really meaty."

It also depends on who makes the tire and what the tires purpose is (summer, winter, all season). In general, summer tires will have a wider tread width and winter and all seasons will have a narrower tread width. In my Bridgestone v Michelin comparison, the Bridgestones were technically "summer only tires" but were more a 3 season tire, spring, summer and fall, not recommended to be used at or near freezing temps. Where as the Michelins are Summer Only - do not use at or near freezing. They aren't great in the wet either, not dangerous but not actually all that safe either. 7/32" tread depth is not a lot of depth.

For what it's worth, 16x7 and 17x7 look nice and meaty on MINI's. I'd recommend 16x7's in 205/55. I had those on my Justa and the taller sidewall did two things - slightly more comfortable daily driving and they filled the wheel gap COMPLETELY with ZERO rubbing with Megan Racing Euro2 coil-overs and stock suspension. They also looked great on the car.

If the deal on the wheel/tire package is incredible, perhaps jump on it but I'd be taking into consideration the cost of spacers, longer lug bolts and fender rolling. You really don't want to go more than 3mm in spacers before you get longer lug bolts.

Look at the photo on post 15). Very telling on Tire width variation

thanks for all the great info ,and suggestions, it Definetely helps me in understanding more about this setup. it is really starting to look like i may have to just pass due to the incured costs and headaches that may happen if i have to start adding stud, spacers , ect. Also don't feel good about starting to have to do fender rolling .

i may ask the seller if hes interested perhaps we can test fit one on the mini and go from there,, but i dont think people really want to be bothered .

Ironicaly the rims/tires were off a newer miata i believe . From what I gathered online it seems like the miata somehow allows for a wider setup than the mini it seems . The tires on the rims by the way are 225/45 r17 hankook ventus rs4 and look quite flush with outside of rim and dont look stretched much , then again my eye is not trained so i may be missing something ,lol.
. The tires have some decent reviews for street driving also, which is what I would need it for . not planning on tracking yet, and will Definetely be switching it up to dedicated winter rim/tires flis i decide to take the mini out for a couple times .

In my opinion, 225/45-17 is too big for the Miata, too. The ND Miata also has much more room under the fenders than the Mini.

My other opinion is that 17x7 +40 or 17x7.5 +45 is ideal wheel size for the Mini. And, depending on goals, either a 205/45-17 or a 215/45-17 would be the ideal tire size for the Mini.

I ran 225/45/17 mounted on Enkei PF01 wheels, but I don't remember what the offset was and don't have the car anymore. No rubbing issues whatsoever.

If not a custom offering, the PF01s in 17s would have a 45 mm offset for 17x7s ( note - this is not an 8.5 inch wide wheel. However, 225/45/17s will stretch on a 8.5 wide rim - but that is the easy part. Fitting on your car is where the real effort begins )

Yes, to be clear, these were not custom wheels, so offset of 45mm would be correct.

Thank you to all for your input. In the end the concensus seems that the 225 /45 on a 8.5 rim will just be too much . Especially considering all the extra work involved and parts to buy in order to.make them fit .

I agree the 7.5 rim with a 215 tire may be the best combo for me . Asthetically and so i can put a little more rubber to the ground on spirited drives . Also like the idea of a simpler install and not having to fender roll, etc .

One thing I had not realized also.is that the center bore on these rims.were 74mm I believe , so I would also need the hubcentric ring to convert them down to the r53 bore .

A question i have is...... Is considered safe/unsafe to use hubcentric rings paired with a wheel spacer ? ( example 5mm?) This is just for my curiosity as I am still a newbie to this whole wheel business.

Not quite correct - teh 225/45s on an 8.5 rim is okay. The 8.5 rim on your mini is the challenge

I've run 8x15 +45 on a R53, but not 8.5. I was NOT running OEM struts however.
