![]() Standard mobility kit seems the norm going forward. So it appears BMW are phasing out the use of Runflat tyres and the reason is to reduce weight and therefore to reduce CO2 emissions. Why have BMW stopped using run flat tyres? 5 thread type and will convert your vehicle’s centre bore from 72.5mm to 57.1mm. These PCD hub adapters are 45mm in thickness, feature an M14x1. These 5×120 to 5×112 PCD adapters are designed to change your PCD from 5×120 to 5×112, and simply fit on to your vehicle’s existing wheel hub. ![]() Does 5×112 fit BMW?ĥ×112 wheel weights, sizes from other models and tyre options – BMW 5-Series Forum (G30) As a lot of you will know, BMW changed their bolt pattern (PCD) to 5×112 from 5×120, after about 40 years, with the newest cars they’ve launched, including the G01 X3, G30/31 5 series, G32 6 GT and G11/12 7 series. Like many cars, BMWs now come equipped with “run-flat” type tires. Most other models come equipped with run-flat tires. Some models, especially performance-based M vehicles, come with BMW Mobility Kits in place of a spare tire. In other words, the handling difference is a matter of feel, not grip, and is at worst a minor thing.Load full table of contents. And while increasing the stock pressures by 3~4 psi ameliorated the mushiness, I usually ignored it and enjoyed the much more comfortable ride. But even though the steering feedback was a tad mushy, the wet and dry grip was actually IMPROVED by the DWS rubber. 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. Order the wheels then go and have the tires installed locally. Less than $200 for the 275 and about $160 for the 235. They make a great 19" tire that has great treadwear and good grip in the wet and dry. The mechanic was mixing two things how soft the suspension is over bumps and roll in a corner. Going to a 19" wheel non-RFT will give a better ride and the handling characteristics will be similar. When owners swap to softer sidewall tires (more flex) some mushiness is Having an extremely stiff sidewall (provided by run-flat tires) allowed the BMW engineers to soften the suspension characteristics a bit. 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?"Ī BMW service tech told me he's had a number of people complain after theyĭitched their run-flats saying their car doesn't handle as well as it did previously.īecause the suspension was tuned with and for run-flats. 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. Basically only able to sell 2 to someone who cracked one. Selling the wheels has been a slow process. 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). Last year, I decided to go aftermarket wheels and I did the Apex EC-7s. Maybe a BMW owner parting out their car before trade might want them, I"m not sure who else would. We have a used tire dealer in Tampa with a broad selection of tires and the run-flats sell for a price concession. I don't think the market is great for used run-flats. Your 162s are nice wheels but I doubt you'd see more than $500 for wheels alone. Shipping puts a big hole in the economics for both buyer and seller. Even more so if you try to sell tires along with them. 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. I would first try selling on your regional forum or craigslist.
