Since my wife traded her/our C-MAX I obviously don’t visit here as much as I have in the past. Sorry I missed your post komondor and that I missed this thread being updated until ldcarson kindly did.
Like I mentioned, I would look at light wheels to try to compensate for the added runflat weight. The time my wife traded it in I was starting to look at tires for the C-MAX. I was also hoping she’d get some light weight wheels. Tire Rack has a sort function that sorts by weight. Even America’s Tire/Discount Tire (www.tires.com) lists the weight of their wheels, but no sort by weight.
I was looking at getting the silver version of these:
Seems like they are going to stop selling them, silver are on closeout. For the Sienna my local America’s Tire was where I purchased a set of Enkei PF01s. They are a little heavier than RPF1s but the RPF1s were not listed as an option for the van, maybe too little weight carrying capacity.
