Measuring wheels

[tvrgeek]

Did not see any measurements, so this is the little I have gathered.

Sure would be nice if there was a spreadsheet of tires with wheel specifics for combination known to fit posted somewhere. Example, does a 225/50 on a 17 with 40mm offset clear? What 225's on what offsets actually clear?

 

S-Winders ( what came on my 09 S)

 

6 ½ x 16” 48mm offset spec. I measure 49.5, #71193A

195/55/15 Mounted section width is 205 mm

Rear clearance, Hub to section edge 152 mm

38 Lbs mounted., so tire 23 Lbs, wheel is 15 Lbs, very light.

 

 

S-lite Picked up used.

 

7 x 17” 48mm offset spec. I measure 49.

205/45/17

Mounted section width 208 mm

Rear clearance: Hub to section edge 153 mm

44 Lbs mounted , so 23 Lb tire, wheel is 21 Lbs. Actually not that heavy.

Notice the more square lower profile tire is only 2mm wider than the 195's on the car. Lots more tread though.

 

 

 

Aftermarket wheels run from 16 to 25 Lbs in the 16 and 17 sizes. Big difference.

 

Offsets from 48 to 40.

 

 

My stock tires clear the trailing arm by only about 18mm Some to play with, but not much. 205/55/16's on OEM rims are not a problem. I think I will do this.

 

Tempting 215/55/16 on a 16 x 7 with 40mm. Maybe next time
