I have a 2011 BMW X3. I bought it almost two years ago as a pre-owned. I had an immediate problem with a sound that was traced to a rear tire. To BMW's credit, they replaced all 4 tires at no charge as I had the car for 4 days. That was the good news. The tires are a little hard and a little noisy compared to "normal tires". In 22 months I have driven 44000 miles and I am now in need of tires. The non-RFT from Pirelli would be about $60/tire less expensive and would last, according to two tire places, about 70,000 miles. I am therefore looking for a spare tire option. Beemer (online retailer) offers a donut spare and wheel for $399 and a jack kit, for an all-together $500 price tag. Another option is a compressor with a sealant kit that is good for $80 with the sealant life of 48 months and $30 to replace.
Not sure which I will do yet, but the RFTs are out!
