After 8,500 harsh riding miles on the 18" OEM runflats on my 335i I finally ditched them for Pirelli PZero Nero M+S in stock staggered configuration. Wow-so much smoother and quieter. I would venture to say that they handle better. The roads in Oklahoma are pretty rough and I felt often that a hard bump would kick the non-compliant runflats off to the side a bit-now it tracks straight and true over the rough stuff. Haven't tried them on ice yet but I expect them to be better than than Bridgestones. P.S. bought a conti mobility kit from Tirerack to deal with the potential of a flat.

Welcome to the club! I switched after 600 miles

A new world of driving without those terrible runflats

[adc]

I have almost 500 miles since the switch. I didn't get a chance to drive in the snow yet, only smei-freezing rain - and they were much better than the summer runflats.

It's just that I went a little wider (235/265).

Best decision I made for this car yet. It has regained the compliance that made even sport-suspended BMW's such amazing road cars.

[IM2C]

I did the same after 45 miles. Do you guys carry a spare tire or have tire quick fix? Does BMW assist cover flat tire?

Appears as if you went from high performance summer tires to all season. I would expect a difference.

I have the P Zero Nero M & S as well. I had them on my e90 330 w/ sport and they are fantastic. They're currently plowing through our current Michigan snowstorm aftermath on my 335, in stock sport sizes, and once again, amazing. Great choice, and they're even quieter and softer riding in the summer!

I personally have a full size spare in a bag (cheap 18" rim and cheap Sumitomo HTRZ tire).

Hey, did you throw the 265s on the rear stock rims?

Sure did, perfect fit.

Do you have the sport wheels? In another thread 265s on these wheels were not recommended, no specific reason given. Was thinking of doing it...

[Hops099]

Ditching RFT's as well... have two bubbles from potholes here in DC. Anyone know if it's an issue swapping to non RFT on 162's?

Yes, the standard E92 OEM sport wheels (18", 8" wide fronts and 8.5" rears). There is no reason why 265's won't fit in the rear - absolutely none.

[Bimmer335i]

and what do you guys do with the RFT's? Sell 'em or stack 'em in your garage to collect dust?

I stack'em up and will put them back on the OEM wheels just before the lease end.

Well, my concern is that the 265's are out of spec for the 8.5inch rims.

Look at the recommended rim sizes for the 265. My concern would be that tires would be crowned and roll over like a dog when cornering hard.

I had similar concerns and discussed them with my tire shop, a well regarded outfit in my area - all the racers use them, and they've pretty much seen and done everything.

My installer's concern was with clearance, not crowning. As long as I took responsibility for the clearance, he said the width/rim issue would not be a problem. I am not sure if he was referring to these tires in particular or to the size in general. I thought if it looked or behaved strange, I could adjust the tire pressure to compensate and so decided to go for it - I really wanted the extra width because I thought I'd loose a little dry grip going from summers to all seasons.

I took the plunge anyway because I was so fed up with the runflats, and because I was racking up miles and wanted to be able to put the runflats back at lease end.

What I've found out is that according to my butt meter, these tires have at least as much dry grip as the OEM runflats, and turn-in doesn't seem to have been affected. And they do considerably better in the wet - and I imagine in the snow too. I am running slightly different pressures - increased to 38 all around because I feared a general softening due to the loss of the extra firm runflat tirewall - with no adverse comfort/grip effects.

I can take pictures if you'd like... they're not really bulging out of the rims...


Edit: I noticed you are looking at PS2. I've run PS1 and PS2 on my cars before and have noticed the PS1 are a lot more "square-shouldered" and PS2, which have a rounded shoulder and a more curved tread surface.

So perhaps it could make more of a difference on the PS2 - have you talked to a specialist?

Hey man,

My only experiences are beating the hell out of a 255 race tire on 8.5 inch rims during a few track days. Driving normally, you shouldn't have a problem - so I think you're ok.

I got rid of the RFTs after 1800 miles. Bought the car in Pam Beach Florida drove it fo 1500 miles. The RFTs were OK on the smooth South Florida roads. I had the car shipped to NYC and the car was horrible on NYCs torn up roads. I dreaded potholes - I was sure I would break a rim. I was ready to get rid of thre car regardless of how much money I lost. I posted my concerns (complaints) and a fellow poster urged me to get rid of the RFTs. I replaced the RFTs with Pireslli P_Zero Nero M&S. The ride improved dramatically with no discernable loss of performance.

I have an E93 335I with BMW 196 rims. I have tire/wheel insurance through Auto Club and a Conti Confort Kit - no spare.

I thought something was wrong with my car when I received it. It drove like sh*t. Dealer said no fault found operating as designed. I changed to winters the next day in preparation for November snow and it was like receiving a new car. Run flats are just bad. They drive harsh, sound harsh and do not perform well IMO. But they have their place for those who are happy with them.

[BMW MotorSport]

yeah now everyone knows for sure run flats are no good.

[mid-corner fun]

I'm in the same situation. I got my 335i Coupe with 18" potenzas a few days ago, bone-jarring ride over the smallest potholes/bumps. On top of that, the car is not tracking straight after hitting potholes/bumps but has a tendency to veer left/right instead. Didn't notice any of this in the autobahn but then again...there were zero potholes!!!

Too late for winter 17s I guess, I'm thinking of replacing the RFTs with Pzero neros.

A couple of Qs:
-How easy/hard is it to sell the 18" OEMs with a few hundred miles on them?
-Going from RFT to non-RFT, do I have to select an installer that deals with runflats (to unmount) or doesn't matter? Most recommended installers in my area don't deal with RFTs.

thx

Not very hard - but you will only get some $600 for them. Tops.

If I were you, I'd keep them and install them back on the car when you sell it (or the lease ends). Many prospective buyers will want the RFT on the car for safety reasons, at least until they splurge for a spare. And at lease end, you have to return it with runflats...

-Going from RFT to non-RFT, do I have to select an installer that deals with runflats (to unmount) or doesn't matter?

Yes, otherwise they will get damaged. Nowadays, plenty shops can deal with runflats. Find a good one - and stick with it.
