Hey guys do many of you got rid of stocks w run flats and went aftermarket? If so I'm assuming the new setup I'd just buy w the tpms on them so wouldn't need to take off current wheels? What would a set in perfect condition with hankook ventus s1 mobile tires size 225 35 18 w good tread and rims below be going for if I decided to sell where would be best route to sell online?

[jwalker87]

I'm confused. Do you plan on replacing your tires with non-runflats, or do you want to replace the wheels as well?

Lots of people ditch the runflats, with good results. Just be sure to have a AAA card, since you now have no runflats and no spare tire. I highly recommend Michelin PSS. They are expensive, but sooooo worth it.

As for wheels, I highly recommend Apex Wheels. They make fitments specifically for BMWs, which means you can probably get what you want without spacers, and the BMW center caps fit, and the TPMS fits perfectly. I plan on replacing my 162s with a set of EC-7s as soon as my current tires are doneski.

[jk315]

No I wanna get just regular tires and aftermarket wheels that come w tpms sensors on them that will bolt right up to the stock system.

I have the Hankook S1Noble2's and love them, VERY grippy on dry roads, great on wet roads, and quiet. Haven't tried them in light snow yet, but they're rated by TireRack as the #1 Ultra high performance all season tire, beating DWS's, etc.

Checkout the vendor section for Wheels & Tires, find a vendor, and shoot them a PM with what you're looking for. They will ensure you get the right TPMS, etc.

Seeing as we have identical cars, here are the full details that I've researched and plan to execute when my current tires are up:

Stock specs
Front: 8x18 et34. 225/40-18
Rear: 8.5x18 et37. 255/35-18

Apex EC-7
Front: 9x19 et35 (22.8 lbs) (sticks out 12mm more than stock. 14mm less inner clearance)
-255/30-19: 0.284% smaller diameter
Rear: 9.5x19 et33 (22.5 lbs) (sticks out 17mm more than stock. 9mm less inner clearance)
-275/30-19: 1.838% larger diameter

Tires: Front: $263 each
Rear: $309 each
Total: $1144

Wheels: Front: $349 each
Rear: $369 each
Total: $1436

Total: $2580

Tires are Michelin PSS from Tire Rack. Wheels are Apex EC-7 direct from Apex as linked above. Apex sells TPMS sensors for $55 each, so you can have those come with the wheels.

ditch the runflats, get regular tires and buy a slime flat repair in place of a spare and call it a day

Is your E90 a 2008 YM as your sig says ? If so, are you sure you've got TPS in the wheels ? I thought this was a 2010+ thing with earlier cars using a wheel speed difference as measured by the ABS senors....

I could be wrong but my UK 2008 E91 does not have TPS in the wheels.

I got rid of them, never looked back.

[Dark_Knight_335]

Don't think about it just do it- run-farts are garbage.

[udm328i]

Bridgestone has these new rft's, "driveguard", supposedly better than the original run flats that came on our cars, " a smoother riding runflat"

[mlifxs]

on selling your current wheels / tires:

I would first try selling on your regional forum or craigslist. Shipping costs have increased: if you sell on ebay or here, it will cost you probably 30-40 per wheel to ship over 1000 miles. Even more so if you try to sell tires along with them. Shipping puts a big hole in the economics for both buyer and seller.

Your 162s are nice wheels but I doubt you'd see more than $500 for wheels alone.

I don't think the market is great for used run-flats. We have a used tire dealer in Tampa with a broad selection of tires and the run-flats sell for a price concession. Maybe a BMW owner parting out their car before trade might want them, I"m not sure who else would.

********
Last year, I decided to go aftermarket wheels and I did the Apex EC-7s. I deliberately timed the purchase to coincide with changing my tires, so I didn't need to worry about the tires in the equation (and I was changing rim diameter / width anyhow).

Selling the wheels has been a slow process. Basically only able to sell 2 to someone who cracked one. Still have two. Not easy to market oem wheels, maybe it's easier for someone who lives in a BMW / population dense market like LA, but not here. Prices for used parts on our cars seem to be cheapening, as the real question becomes, "hey e90poster, when do you plan to trade in your car for a new one?"

[ShaverZBT]

I don't know. My run-flats ride great on my M-Sport. They are Pirellis on a staggered set-up and I have no problems with them. They are not loud either.

On the flip-side, my wife has Continental run-flats and they suck. Too loud and they do not have very good grip. So, they will be upgraded for sure.

[talyler]

Switch to PSS and don't look back I have a spare tire in the trunk. It takes up a decent amount of space but I make it work. I could still kick BMW for forcing people to have run flats with no spare...

[Eat.Sleep.Race]

Go with Michelin Pilot Super Sport if you have the budget too. If not Ventus V12's are nice all around tire.

[jt335i]

+1 on the Michelin Pilot Super Sports. Stick to the road like glue even in wet weather. They were recommended to me by a personal friend who’s a professional race car driver. Cost more, but they're well worth the $$$ I paid for them. Definitely will need AAA or some kind of road side assistance since you have no spare, but you can buy a spare/jack/wrench kit online or find them piece by piece at a local junk yard (if in stock) or buy at the stealership. Me, I bought a compact spare at a junk yard (LKQ) and rigged together a heavy duty lug wrench. Just need a jack which I’m still searching.

As for selling the stock rims and tires, everyone else pretty much summed it up.

Not to completely divert the thread, but is that an aftermarket rear bumper or is that an aftermarket diffuser on a stock bumper?

That's the M-Sport bumper.

I'm very curious about these. I might even get them for my next set. I'm interested to see how the long-term reviews by customers on Tire Rack's site turn out.

Even with RFTs though, I keep a full-size spare in the trunk of my car. My only concern about that though is just the weight (maybe about an extra 40-50 lbs). I'm thinking about only carrying the spare in there when I'm on longer road trips.

Otherwise, as far as non-RFTs go, I've always had great experiences with Continental DWS. EDIT: Had these on my coupe. Currently running Continental ContiProContact SSR or whatever all-season tires on my E90 that I picked up in late August. The tires were new on the car as part of reconditioning it for CPO sale.

[udm328i]

^ yea I'm thinking about getting these too, also running conti dws now and keep a spare in the trunk.

ALSO...

A BMW service tech told me he's had a number of people complain after they
ditched their run-flats saying their car doesn't handle as well as it did previously.

Why?

Because the suspension was tuned with and for run-flats. Having an extremely stiff sidewall (provided by run-flat tires) allowed the BMW engineers to soften the suspension characteristics a bit.

When owners swap to softer sidewall tires (more flex) some mushiness is
added to the equation.

Caveat Emptor!

Hogwash.
Going to a 19" wheel non-RFT will give a better ride and the handling characteristics will be similar.

The mechanic was mixing two things; how soft the suspension is over bumps and roll in a corner.

Don't believe the hype.
OP - also look at Falken tires.
They make a great 19" tire that has great treadwear and good grip in the wet and dry.

It's the Falken 722 -> http://www.falkentire.com/tires/car-...s-pt722/s-tire

http://www.discounttiredirect.com/di...0&rd=19&cs=275
http://www.discounttiredirect.com/di...5&rd=19&cs=235

Less than $200 for the 275 and about $160 for the 235.
you can get them at America's Tire.

Order the wheels then go and have the tires installed locally.

[QUOTE]

I observed that there was some truth to this when I went from the OEM Goodyear summer RFTs to Conti DWS tires on my 128i convertible - apparently due to the softer sidewall construction. But even though the steering feedback was a tad mushy, the wet and dry grip was actually IMPROVED by the DWS rubber. And while increasing the stock pressures by 3~4 psi ameliorated the mushiness, I usually ignored it and enjoyed the much more comfortable ride.

In other words, the handling difference is a matter of feel, not grip, and is at worst a minor thing.
