Im pretty sure this has been asked but I cant find it in the forums!!

Mines a daily and living in quite a rural location I always used to run good quality winters on my MX-5's and the few occasions we had snow they were invaluable.

So Im looking at cross climates for late November to March specifically Michelin Cross Climate 2 and Hankook Kinergy 4S 2 ( Used to run Hankook Winters and they are a great tyre!!)

Choice in 215 40 18 is super limited and very expensive!!

So seeking guidance from the wise will a 225 40 18 fit on a stock rim and what are the downsides if so of doing so?
 
Yes, I run 225 40 18 on the stock wheels and no issue, it's the max tyre width though I'd say for the oem wheels. Marginal gain in height, cheaper, ideally I'd run them on 8J width wheels to keep it sharp on handling, but haven't bought those yet.

Any disadvantage to running 225 width tyres on OEM wheels then? Do they affect handling negatively, or do they ride softer/harsher? If the only difference is 225s are cheaper, I guess there's no reason not to switch to them.

Main thing would be increased fuel consumption, minor weight increase, less steering feel, less playful handling - they went with 215s for a reason! But as you say, 225s are cheaper, the increase in sidewall might fractionally soften the ride, and cause speedo to under read (but usually there's enough tolerance for this).

I'm thinking you're right about them going with 215s for a reason. I know it's nice a save a bit of money, but, insurance companies will find any excuse to not pay out, and changing tyres to anything not standard (not as per the standard vehicle specification) could be an excuse for them if they've not been made aware.
 
225/40 on a 7.5j fits nicely.

For reference here are some Advans fitted to my erm... Advans.

Those wheels are identical in size and offset to the stock GR86 wheels, as you can see nice flat sidewalls no stretch. No adverse effects to the steering or response. I intend on swapping to 225s when my PS4's are done, alot cheaper alot more variety.

Those wheels are up for grabs if anyones interested 😅

They work for daily driving but the wheels do not support the tire enough for performance driving, you will get a bit mushy feeling if loading them sideways in a turn. I run 9" wide wheels with 225 tires for track.
 
I've driven the same tyres back to back on 8J vs the stock 7.5J. I sold my 8J and liked these tyres so moved them onto the oem wheels, I can confirm they're a bit softer and slightly more mushy, not loads in it but don't get the same feedback as I did on the 8s, and actually aren't as playful. I think 215 on the stock wheel width was the right move by Toyota
