i have the stock 16" rims and goodyear runflats on my 03MCS. I am looking at a set of forged 17"rims that weigh 17lbs each and want to change fom runflats to regular dunlop tires. does anyone know aprox how much, if any, weight will be saved by making the switch? If the weight difference isnt that much i may as well not spend the extra cash on the forged rims over regular ones.

 

A quick trip to the Tire Rack site shows:

SSR 17x7.5 ET 42, 14.5# $513 each
http://www.tirerack.com/wheels/Wheel...All&sort=Brand
BBS RGR 17x7 ET 38, 16.3# $610 each
http://www.tirerack.com/wheels/Wheel...All&sort=Brand

Both are low stock at tire rack now, would have to wait to get a full set of 4.

 

thanks for the info. any idea what the stock rims weigh in at? i know i could just pull one off the car but i dont have a scale ( not even a bathroom one )

 

I belive the 17" S-lites weigh between 22 - 24 lbs.

 

Closer to 24, 25 maybe.

 

My S-lites acc. to bathroom scale weigh in a 23 lbs.

 

Oem 17" wheels vary from 21.9 to 25.1# according to this faq
http://www.mini2.com/forum/faq.php?f...factory_wheels
Stock Goodyear runflats are 22#
Dunlop non-runflats are 20# in same size.
so
you'd save about 7.6# to 12.6# per wheel/tire depending on
which ones we're talking about compared to oem 17" wheels.

Comparing to the oem 16" wheels (17.5 to 21#) with 22-24# Goodyear runflats,
17" forged wheels with Dunlop non-runflats would be between 3 and 10.5# lighter per wheel/tire.

 

Plus his would even be less if he sticks with 16's.

 

Why are so many people talking about the 17" S-Lite weights?

 

Because he didn't specify what 16" rims he had, but it seems he wants to go with 17's now.
