So, I've just recently acquired an '06 e90 330i with sport package meaning it has the stock 162 style wheels, with the Bridgestone Potenza runflats. The only thing is that I want to switch to a 19" rim requiring me to get new tires as well, and on a budget no less. So I'm thinking of selling the wheels which are in good condition on eBay to try to get the most cash out of them ($250-270/wheel), and then selling the tires which probably have 50% treadlife here on the forum for idk, $300 for all 4, hopefully putting me at about $1300-1400 in the pocket. Then I'd end up going with some 19" VMR V701's and Michelin PSS all around coming in at around $2300 including tax, meaning my net expense would be about $900-950, which fits in my budget. Any thoughts on getting the most money as possible out of the OEM's without ripping somebody off?
