I have started planning for replacement tires for my 35i.

I have - optional - 20" Pirelli P ZERO RFT:s, which I, after lowering, am happy with performance, but not life nor comfort.

My top picks would be: Continental Sport Contact 6 or Michelin Pilot Super Sport - both non-RFT.

I can find both in 275/35-20, but not 245/45-20.

My best shot is, probably, to buy tires developed for M40i.

Normally a manufacturer will approve, at least, two tires for a model.

So, my question: what tires have been on your M40i:s?

[elimpfor]

We have the Michelin Pilot Super Sport.

elimpfor - thanks! I take it they are RFT:s. It means that shortly Michelin will have also 245/45-20 in Sweden-at least RFT:s.

As mentioned - normally there should be - at least - two approved brands.

Any other brand?

[elimpfor]

Don't know about the other brands, but the PSS are not RFT. At least mine aren't.

Does it mean that your car came with sealent/slime/gunk and 12V compressor? Otherwise I recommend you to buy a set. See thread on X3 forum.

I have made two mistakes:
-my front tires are 245/40-20 NOT 245/45-20
-M40i has 19" tires as STD - NOT 20". Only owner who has announced that he has opted for M310:s with 20" is SANK, who kept his from previous car.

Michelin Pilot Super Sport non-RFT is available in 275/35-20 and 245/40-20
Continental Sport Contact 6 is not - yet - available in 245/40-20

The remaining question - out of curiosity: has M40i non_RFT:s and sealent/slime/gunk and 12V compressor?

In Canada we get the 20" PSS standard and they are non-RFT, as I had previously mentioned. I do have the tire fix baggy which has the sealant and I assume the compressor (didn't open it, don't care, if I have a flat I will use the road assistance).

OK. Thanks!
