utajoker · 22 Apr 2014 at 12:03

Hi

Want to get rid of my run flats in a few months so what is the general consensus on what to replace them with on 330i e92.

not sure on my tyre size, is it 18" rims?

Am i looking at £150ish a tyre?

Also since there is no spare, what do i need in case of puncture?

Thanks

Something like Goodyear Eagle F1 Assymetric 2 will be perfect.

Erm nobody but you is going to know what wheels are fitted to your car? Go and have a look

It's an SE so they could be 17" or 18".

car is not with me at the moment, thought there might be set size with standard wheels. but i guess there are still a few wheel sizes to go from.

I initially thought f1's. Shall get the exact sizes when i get the car back later.

Just something to note, fairly sure I read somewhere that if you replace your tyres with non run-flats you have to declare it to your insurance as the car isn't how it left the factory, so technically a modification

Doubt it will affect the premium much at all, definitely worth letting them know though

Didn't even think of that, thanks.

If you put your reg into black circles it usually gives your tyre size. Worth a try although it might suggest more than one size.

I put Vredstein Sessantas on my 335d. Great tyres, cheaper than Goodyear etc... Great in Wet and Dry, nice looking tread pattern, and lasted ages (after 16k on them I still had 5.5mm on the front and 5mm on the rears). Would highly recommend them.

For standard 18's they will likely be 225/40/18 on the front and 255/35/18 on the back. My 3SDM's were wider (8.5 fronts and 9.5 rears) and had the same tyre sizes as standard and they were perfect, even with a touch of stretch.

I went from Bridgestone RE050A RFTs to Goodyear Eagle F1 AS2s on my E92 330D and the difference is absolutely night and day. Would highly recommend the Goodyears.

For a compressor/sealant kit pick up the Airman Req-Q tyre repair kit. This is the exact same equipment as the BMW mobility kit, you're just not paying for the BMW badge. Mine was £38 delivered off eBay, instead of £105 for the BMW kit. It uses the same design as the BMW Mobility kit with a valve-through sealant bottle, meaning the compressor stays clean if you use the sealant and also you should be able to use the BMW brand sealant if you ever need to replace it. Comes in a nice little bag for stowing too.

EDIT: Seems its available on Amazon now for ~£30 delivered.

I put Eagle F1's on my Z4. Rears lasted 20k and the fronts are on just over 30k with a load of tread left.

Another vote for EF1AS's, 335i came with them but have driven a fair few E9X's on either Bridgestone or Conti RFT's and as mentioned its a massive improvement.

Depending on rim size, width & profile about £150pc should be sufficient.

decision made then

my uncle who owns a garage is getting me a price.

Thanks all.

I recently replaced the horrible Bridgestone RFT's on my 335i for the Goodyear EF1 AS2's - as mentioned the difference is night and day. By far the best change I've made to the car. I actually changed the wheels from 17" to 18" at the same time yet it's still significantly more comfortable despite the size increase.

This is a load of ******** is it not?

Seriously, say if some average guy bought this car in 10 years time, it's not like he would check if it came with run flats from the factory or normal tyres...

xs2man · 24 Apr 2014 at 00:14

Be wary that any breakdown cover you might have isn't meant to be covered if you don't have RFT's on a car that came from the factory with RFT's.

Not sure, just what I've read

If you google it there are quite a few threads on it with varying opinions... I'd say best to tell the insurance, better than them not paying out as technically you've made a modification to the car from its original factory spec

Its internet scaremongering at it's worst, like telling your insurance company you are running winter tyres.

Using this logic you should also tell your insurance company if you service the car using non factory parts!

Insurance company couldn't care less - so long as it has legal tyres on

This is true. The BMW recovery won't come and change your tyre on the roadside if you have changed away from RFTs.

Erm, I tell my insurance company when I use winter tyres. Although, to be fair, I am changing to winter wheels at the same time.

His point was that you don't need to.

Unless you are with Switcover, eCar, Octagon or Covea.
