Smile going from rft to normal tires

Hey everyone, so i'm planning to go from rft to normal tires on my 2006 325i. I did couple research online and it seems a lot of people done that already without any problem even though stealership said it's not ok to switch from rft to normal but who cares i said they are stealership and not dealership. I have couple questions, do i have to buy new wheels to run normal tires or its fine to run the tires on the same wheels and my second question is where can i find a spare to have on my car and what size it should be? Thank you all

Stock wheels are good to go with get-flats. Two most popular tires for non/light snow states seem to be Michelin PPS & Conti DW. You can run oversized tires but need to consider a few things. The actual wheel width will limit your tire width selection & the physical size of the tire will limit fitment.

I have DW's in 245X35X19 – 265X30X19 on 313 wheels @ 8.0"/9.0" wide. 275X30X19 will fit but were out of stock. Some of the smaller diameter wheels are narrower so you need to check if you want to go oversize. Its a bad plan to exceed the wheels recommended tire width.

Good work MP3...Looks like a lot of brands , such as Audi, no longer are using RFTs after 2011. If that's the case can we only hope that BMW follows?

Non-RFT's on my '06 325i for over a year, no issues. Better ride, quieter, stickier, but you'll have to adjust to the feel of a softer sidewall.

Good news. Tischer BMW (DC Area) Sells a complete compact spare tire kit. Tire, wheel, jack, wrench. It fits nicely in the trunk and still leaves some space for some luggage.
I seem to remember it was ~$300. I replaced my RFT's with Conti DWS, bought the spare tire kit and had money left over.

I bit the bullet and got rid of my run flats with 80% tread remaining after 5 months of ownership. Run flats + sports suspension + 18 inch wheels were insufferable on Australian roads. I chose the Goodyear F1 Asymmetric 2 (the yellow E92 they use in their promotion photos sold me) and they simply transformed the car. You will have no regrets.

I replaced rft in my Corvette for many years with better, cheaper, quieter, & better handling reg tires. I carry a tire inflator, sealer kit & AAA card. Lots of Discount Tires stores around the big city anyways. Never had a problem yet...

Same with NYC roads. I got rid of the RFTs after 2 weeks in NYC. They had 2,000 miles on them most of which was put on in South Florida where the RFTs were not really an issue. The sport suspension still sucked and I was regularly getting "Pothole Explosions" and destroyed 7 tires and bent 5 rims.

I am now running Continental Extreme Contact DWS tires and Koni FSD shocks. I am very satisfied with the results and have not damaged any more tires or rims. I now have the car that I thought I bought.

I also own a 2006 325i and the previous owner had installed a set of BF Goodrich G-Force Sport tires. I probably wouldn't have bought them myself (I like Michelin Pilot Sport PS2s) but I am impressed with the ride and handling of these rather inexpensive performance tires (at least in dry conditions).

They are quite a bit less expensive than some of the other tires that are being recommended in this thread and on a 325i I think they are plenty aggressive.


Here is an independent review about replacing BMW run flats that rates them pretty highly.

I second the BF Goodrich g-force sport (comp-2 these days). Just put some on my MX-5 and they have incredible grip in the dry and wet. Summer only tire so a set of winter wheels are needed: I use Khumo Ecsta 4x over winter which are highly rated but come no where near this summer tire

Also the sports package on my E93 has worked out fine here in North Atlanta suburbs. It really sucked on my E92 in Greenwich/Stamford Connecticut - was far too rough a ride for their streets.

Dumped the RFTs, put Bridgestone Potenza RE760 on the stock wheels, carry a mobility kit and enjoy the ride. It works for me.
Occasionally think about a spare tire kit but we don't lose sleep over it. Lots of spare tire & jack kits out there.

The best thing I did was replace the OEM Runflats with Non-Runflat tires. (Conti DSW's) I now enjoy driving the car now. I have a flat tire repair kit and a small portable air pump in the trunk.

I just got rid of the run flats, I ran them down to about 5k left on the front and not much on the back. I love the Pilot Super Sports that I put on. It makes the car ride and handle so much better. It really is an automotive crime to put RFT on a car that is designed to handle like a BMW.
I wish I had put go flats on sooner. N4S

I'm new to run flats and for that matter Bimmers.

But here's my 2 penneth...

I've got 18" Mitchy Pilots (groan ) run flats (came with the car when I bought it last Sept) and therefore no spare. Fronts were new. Rears getting thinner by the day.

My take is that if I get a slowish puncture I can drive to a garage without ripping my rims to shreds. If I go over something that loses all pressure immediately there is less chance of me ending on my roof and in an early grave...on VERY thin rims... because they are run-flats. Sooo...when the time comes, for the sake of a softer ride/better cornering, is it worth it for the perceived decrease in safety???

Alright, I'll get my coat.



Edit...Are non RFT easier on wheel barrings re pot-holes???

I just bought Bridgestone Pole Position RE970as RFT in March. I actually picked one up and they are very heavy. I will keep these for a while but I'm really torn- I have the quite unforgiving '07 xi suspension and I bubbled one of the Bridgestones shortly after installing on some outrageous potholes on the Mass Pike. And I only have 16" rims.
I have a cycle going through my head- if I buy non-RFT maybe they will be more supple and forgiving, but on the other hand this suspension is brutal in certain situations and if I get a flat I'm screwed. I have had a puncture with this car before that allowed no air at all to remain in the tire, so the RFT was the only thing that kept me going. Many of my jobs are the kind I have to be at, period, no excuses.
I will say, the Bridgestones have more grip than the Continental touring tires they replaced. It didn't really handle like a sports sedan with those. But I used to be a Miata guy and I loved how low unsprung weight could help the handling.
How do you experts perceive the tradeoffs?

I had RFT's on my car when I bought it last September. This winter, I replaced them - installed snow tires on the same rims.
From my experience, ride on regular (snow) tires was softer/quieter than run flats.

You can pick up spare tire in pretty much any tire shop - just get the tire size info from the side wall of your current tires (or even better, just stop by the tire shop and ask for a quote - let them check the tire size)

going from rft to normal tires

Just swapped out PS2 RFTs for PSS and are loving not having the RFTs. Haven't tested the grip of the PSS, but they are so much smoother and quieter. I just ordered the spare tire from bimmerzone because I am going on a long road trip and want a spare since the inflator and repair kits don't always work.

Re: going from rft to normal tires

In my opinion, I'll take safety over comfort any day. Just the thought that it's safer with the rft when I'm on the road witb my son, is enough.
I used to drive a mondeo, and the bimmer with rft is much smoother and better.
People who buy an Audi even have firmer suspension, they get used to it 2. And people lower their cars and put stiffer suspension on it, but when you get that from a tyre, it's all bad...
Just my thoughts on this

Found a potentially really good deal today on some non run flats from a friend of a friend. He owns his own shop here in Anaheim, Ca. and told me I definitely don't want run flats anymore on my bimmer. He is getting me the BF Goodrich G-Force Sports Series for $680.00 installed...cash price! Let me know if you want his shop and contact info if you ive locally. He said he can't beat tirerack prices but if you pay cash he doesn't charge for mounting balancing, disposal fees, etc. My buddy that connected me to him is a very trusted mechanic that has saved me $$$$ over the years and will tackle any job with the right you tube video or .pdf file He said he could also get the Conti DSWs but they were a couple hundred more and hasn't seen much difference from those tires based on customer feedback and testing but said they are really good tires as well. Any thoughts?
