How important is tyre size for stock rims on a MPS6?

[Pistol Pete]

I'm in desperate need of a set of new tyres for the Mps6 and the OEM sizing is proving a little hard to find. (215/45r18)…

So I’m asking the question- Is there any reason I can’t fir a different size on the stock rims…?

I understand if you go too wide or narrow you can deform (bow or stretch) the tyre and get uneven wear and strange handling characteristics from it. Also if you reduce the side wall size you will slightly alter the rolling diameter of the wheel/tyre combo. I would like to keep the stock size but im open to a small change in size if there are no tradeoffs in regards to wear and handling.

I want a tyre that displays good handling but rides well, is quiet and wears well. (Not asking for much am I).

Its hard to get everything you list! there will always be a compromise somewhere. Look at Kumhos ku 31's not going to brake the bank and members here love them, they are a good compromise Im running Toyos t1'rs great grip wet and dry, quiet, comfortable, but not a long life ( thats my compromise)

225/45 is a much more common size, which you'll find easier to find, and easier on the wallet
in order to get what you've asked for, you're probably looking at something like the michelen pilot sport 3, or the hankook ventus V12, and they're probably going to set you back mid-high 200's each

KU31's are a good tyre for the price (~150-180 a corner) but if you're prepared to pay more, you can do better

225/40 is really common, and cheap, and will give pretty close to the OEM size rolling diameter.
225/45 will be a bit taller, bit better ride and more accurate speedo (stock is a fair way off usually)

Really any 225 tyre will be fine on the stock rim.

Yeah everyone seems to rave about the KU31’s and they had made the short list however so had the KU36’s and the Goodyear Eagle F1 Asymmetric. It will all come down to price and availability I guess.

However the real issue I had and has been covered briefly above is that I can run a 225/40r18 or 225/45r18 tyre on my stock rims with out issues. I do know the MPS6 is a bit touchy regarding tyre sizes

I have 225/45/18's and they fill the wheel arch nicely imho.

Like said in the above posts, a 225/45-18 or 225/40-18 will be fine, and should fit with no issues.

As far as tyre types, KU31 is probably the best bang for buck tyre around.

If you are willing to spend a bit more though, the Michelin PS3 or Hankook Ventus V12 are both top notch tyres, and provide an extra level of grip over the KU31, while still being quiet, well wearing tyres.

I have 225 40 18's I think, when I compaired them to the original size the rolling dia was the same so on they went lol
