Wow, a lot of interesting insight, thanks so far. The prevailing sentiment seems to be that moving to a lighter wheel will pay more dividends than making a tire switch? This opens a new bag of questions from me but i think i may leave that for a later time.
I asked my previous questions because im in the process of making the switch over to winter tires and the plan currently is to buy a staggered set of non-RFT 18"'s to wrap around my 162's. More specifically, Pirelli w240 Sottozero's (the only set anyone can find around here, ill be lucky if i even get these). My hope currently is that i will notice enough of an improvement when running on those that i can ditch my stock summer run-flats in favor of non-RFT's as well. But again judging from the replies so far, this solution may not work out as well as i hope.
A lighter wheel and non-RFT tires must be the best combination (and the most expsensive), but which of the following combo's would yield the most success in reducing the weight of the steering? 1) Stock wheels + non-RFT, or 2) Light wheels + RFT, assuming all dimensions are the same?
