Replacing Run Flats - Is the spec the same?

DazzaBT said:

The front tyres need replacing on my 2016 Cooper Clubman S. They are currently run flats and I wondered if I replace them with non run flats, will the ride be a bit smoother (I find it a bit too firm on the country lanes on my daily commute).

If I can do that, do I just replace with the same spec (225/40/R18/Y92) but non run flat, and should I do all 4 tyres?

Thanks!

you will never regret changing to normal tyres its changes it all in a good way

Same size/spec as the run-flats. Would be best to go all four, but you can run with front normal and rears run-flat. And as Mike says, you won't regret it. The difference in ride/comfort is quite significant.

I have a question, I currently have 225 45 R18s with run flats on my Countryman ALL4 Cooper S, and I want a smoother (less bumpy) ride too - I will change them for non-run flats, but would it not be more suitable to go for a higher profile tyre? Such as 225 55 R18s?

Thoughts?

Unfortunately, as I found out, the wheel arch can't take anything bigger than the 45 R18, it would rub in the wheel arch.... the only way to increase the amount of tyre would be to fit 17" wheels - that would allow a tyre with more profile, but as I am not replacing my wheels, I didn't investigate....

Anyone have a clue of the biggest profile tyre a 17' wheel can take, without rubbing the wheel arches?

based on the comment before yours where guy says his max profile was 45 or a 18 inch rim, should be same as yours if you had a 18 inch rim, but because as you have small rim by 1 inch, i would guess something like a 60 profile would be max. this said if changing out runflats you should replicate the tyres size from your run flats ie same sizes but non run flat,, i know what you might be thinking ie more rubber better ride that's sort of true but not that important on the mini when getting rid or solid run flats, what you will find is car will behave no tram line banging terrible ride it will all go away and just become a nice car to drive, and the bonus ball the non run flats are cheaper and better fuel uses,

Think I must’ve the only person who actually wants run flats!!! I have been disappointed 3 times now when getting my MINI’s that none of them came with run flats. I drove a friends MINI down to the south of France a few years ago, that had run flats and I loved the harshness of it, gave it more of that go cart feel LOL.

I know what you mean but on British country lanes gets a bit tiring haha
