Seems like an age old conundrum on here.

So do I buy some replacement 255/35/18 RFT rears part worns around £250 or change all four for none RFT's?

Goodyear Eagle F1 Asymmetric 2
225/40 R18 Y (92)
Goodyear Eagle F1 Asymmetric 2
255/35 R18 Y (94)

£384.28 (blackcircles.com, supply only)

My fronts seem to have plenty of tread left.

As long as you're aware of how the tyres react differently, you can mix the two as long as the axles match.

Driving legally you won't notice the difference anyway.

If you want to ditch them that's what I'd do.

I changed my RFTs to the Eagle F1s you have above and then I sold my front Rfts on for £125.
I paid £440 for the Eagle F1s fitted.

The improvement in ride comfort and grip is amazing.

I'm in the same pickle, I've had the Goodyear Eagle F1's on the front which total transformed the car and now using Goodyear Efficient Grip Performance on the fronts due to damage to the Eagle F1s. My rears are due a change in the next few months. I currently have Bridgestone runflats on the rears, I've got 24k miles out of them so far, however I'm tempted to go with Eagle F1s or Efficient Grip Performance on the rear as well as their great tyres and much quieter than the RFTs. My driving style is 300miles a week commuting, mainly motorway and then the rest is urban in and around London.

I'd go for the Eagle F1s all around if I was you Dizzle.

i had the same issue. Went with all 4 non rft's and sold the 2 RFT's on ebay. job done. I wouldnt mix and match tyres.

[Fantastic]

Definitely ditch the rft's

I've got f1's on the front and rft's on the back at the minute, will be replacing them for f1's too when the time comes.

[djgandy]

As many have said, swap the lot, and sell the runflats. They sell for good money even worn.

[AWBimmer]

I've just bought Eagle F1 non RFT on recommendation too and having driven on them in my friends car, the comfort is amazing!

[ahmedb]

Like Dann, I took to the change around 3 months ago.

I'd switch all 4. Comfort is amazing, grip is very good and the wear rate seems pretty good to me so far.

If you have decent RFT's when removed, sell them on ebay. They fetch good money. Just be careful that whoever removes them doesn't damage the inner tyre as the RFT's are a pain to get off.

Switch all 4 tyres. Get a good mid range tyre, such as Hankook and you wont pay a fortune.

[Dace64]

Do you inform your insurance when changing from oem run flats to standard tyres?

[Dizzle]

As usually great feedback - thats why I love this place!

But yeah interestingly as above did you inform insurance for the none standard spec change?

Also what'ya do about punctures? Carry foam / space saver?

[Jeff123]

I have spoken to a couple of insurance companies and they were not really too concerned. They seem to just regard tyres as tyres IMO. One good thing is that BMW's have the TPS and that's a good early warning of a problem.

AA/RAC etc now spend a great deal of time fixing tyre related issues, so for £40 per year that's a good investment.

[Dann]

I've got Rac cover and am getting a mobility kit just in case.

Haven't bothered about insurance company because they are a better load and speed rating than the rfts.
They are the only 2 things that matter between the tyres.

[BMWChap]

Insurance aren't bothered as non RFT's are still legal and not performance enhancing, however if you fitted the wrong size tyre for example wider and were involved in an accident then you may find yourself in trouble with the insurance.

I swapped my rears and noticed the difference immediately.
