Wheel Trade, what's a fair price?

[macming]

So my coworker has a set of 214s with the stock Dunlops that has maybe 100 miles on them. I have a set of 334s with 7/32" tread left on the stock Bridgestones. What do you guys think would be a fair amount of cash for this trade? I'm assuming I'll have to toss some cash his way.

To make the issue a bit more complicated, his wheels may not have TPMS sensors, and I'll likely have to spend $400 on wheel arches. Plus I'll lose the ability to rotate my tires

1. Keep your OE style 334's (as back up or as extra set). You might just get tired of style 214's ...
2. Get style 214, either OE used or aftermarket. Depending on how much of a purist you are, style 214 20-inch aftermarket run about $200/ea, staggered or non staggered. If you go non-staggered, you won't need the fender flares and you can buy one size tire that you can now rotate. See 4. If you do get staggered, I highly recommend the flares because you won't like the look.
3. Get 4 TMPS from BavarianX (BERU brand, OE supplier to BMW).
4. Get 4 non-RFT tires. Consider size 275/45x20 tires ... Make SURE you read the specifications on the tires, e.g the manufacturer's recommended max wheel width that the tire can be mounted on. This size tire is slightly taller than the size(s) BMW recommends for staggered wheels and will give only a 2.5% speedometer error. Acceptable in most cases. Plus you have a much wider variety of brands to choose from (lower prices). If you go staggered with a 10.5 wide wheel, you can still use size a size 275/45x20 tire, just pick a brand that allows you to "stretch" it.
5. Have everything mounted and balanced at a competent shop, using a Hunter GPS 9700

Thanks for the very informative reply! I have a set of OEM 18s for winter, so I should be OK. I'm a little curious why you mentioned that I may get tired of the 214s. Would the ride quality be too harsh? Would they hydroplane easily? I guess I'm trying to figure out the drawbacks of style 214s.

I'd only get 214s if the trade with my coworker goes through. Otherwise, I'll hold onto the 334s. For the time being, I'm perfectly happy with the traction I get from my 334s. The M3 gets really sticky track tires

As far as style 214, "beauty is in the eyes of the beholder". Sometimes I like them, sometime I don't. They are HARD to clean, for sure.

Going from a size 18 or 19 to a size 20 can give you a harsher ride, but again, that depends on your set up (tire size, brand, type etc). Hence my recommendation to go to a slightly "taller" tire, without a loss in performance.
