Hm, I think I need to do the math and look at how much would cost me a set of new 19"non rfts and how much I could get for those part worn fronts.
Then decide if its worth the money.
On my previous car I changed all four tyres with alloys too. Originally I had 17"rft and went to 18" MV3s non rft & it felt like I was driving a completely different car

To my knowledge you can't have a mix of run flats and non run flats. I believe it would fail the MOT.

I didn't know that. Mine car has been in twice for MOT with mixed non RFT on the front and RFT on the back. Passed with no issue.

Hi have just read through this thread and the arguments for/against run flats. i have just bought my first BMW . 3 series E90 2006 325i. This comes with run flats and no storage space in the boot. (although when I look there is a deep well that would probably take half a tyre, why couldn't BMW have just made this full size?) Anyway RFTS's I read can only be driven for 50 miles at 50 mile an hour if you get a puncture. This isn't going to get you home on the motorway on a late evening if you're a long way from home and there's nowhere open to get a replacement and you know damn well that that's where you are going to get a puncture !! So if I change to normal tyres (which I also read that will improve the ride) if I carry a can of gunk/compressor has anyone ever had any experience of this and do they really work? If they don't then the only other option is to carry a space saver wheel in the boot? So I'm wondering ..my daughter has a Mini Cooper which has been fitted with an underfloor storage holder for a spare wheel. Is this available for BMW's or is it not feasible maybe due to where the exhaust runs?

Thanks

When was the last time anyone got a puncture...?

you can't mix RFT and NonRFT on the same axle but it's OK front to back

Punctures are rare. Punctures that stop you driving any further are even more rare.

Usually its what, a nail in the tyre and a slow deflation, some folk leave the nail in for weeks and just keep pumping the tyre up...

While RFT seems like a good idea, are you really going to drive 50miles up a motorway with a flat tyre? I certainly wouldnt. I might limp it to the nearest garage but thats about it.

If you drive on an RFT when its flat you instantly write the tyre off, so a simple nail and easy puncture repair turns into £100+ for a new tyre. If you drive on a non RFT when its flat, you'll also ruin it, but your still in the same position needing a new tyre. At least with the non-RFT and a compressor you'd try to pump it up and might well get to a garage with it inflated and not ruined!

tyre gunk will work on some punctures, but not anything major. rip a tyre on some metal or a kerb or something, your not fixing it and reinflating it with gunk. Also, many places wont do a puncture repair on a tyre thats been gunked, so you've got that to contend with as well.

For me, i have non-runflats, and an AA card. I keep a compressor and gunk in the boot just in case.

Very happy with Vredestein Ultrac Vorti - 235/40 and 265/35 on 18. NRF.
Very grippy - far less wheel spin.

Ive used Dynplug with great success for simple "nail" punctures.

Repairs a tyre for only a few quid.

This Saturday gone I got rid of my Bridgestones RFTs which I had on the rear, I've covered 26k miles on them through most weather conditions. Including some long trips to Italy. On the rear they were not the worst tyre in the world, however when pushing them a little you did notice they skipped around on rough surfaces and the ride was very crashy. In the wet they really grim to use.

Now this week I've been driving on non-RFT Goodyear Eagle F1s on the rears and what a difference. The car is much smoother, quieter and the handling is so much better when you push it around bends. Also since moving away from RFTs I've noticed my mpg is marginally better as well.

At the end of the day, if your happy with RFTs just keep them, if not, change them to non-RFT.

I've been driving with Vredestein Ultrac Vorti - 18" 225/40 and 255/35, non-RFT.

I've had them for over two years and have driven 26k miles on them without a problem. They are wearing out now and need replacing but I think they have had a good innings.

Came here to find out what people are using and to see what I will replace with.

Michelin PS4's are out now, about £470 delivered from what I can see.

Also found Uniroyal RS3's for £275 delivered which seems a good deal. Currently deciding what to fit to my MV3's currently being refurbed.

If you want away from rft the KU39 is a great tyre. I'm on my 3rd set of rears. A great tyre for a superb price. Everyone who has had them has loved them.

Eagle f1 assy 3's are out now i think, but i'll be sticking to Michelin PSS.

Did you get 26k on the rears? Sounds pretty good, I was about to order the Uniroyals RS3's at £275 but the reports of people getting low mileage out of them has made me think twice. Have found the Ultrac Vorti's for £345 so might go for those.

I would probably have gone for these but the rears 255-35-18 are not released until May.
