Stock V8V has 19" wheels that are

Front: 19x8.5, +49 (34 with 15mm spacers).

Rear: 19x10, +59.3 (39.3 with 20mm spacers).

With 245/40ZR19 front tires and 285/35ZR19 rears tires.

245/40ZR19 Diameter: 26.7”

285/35ZR19 Diameter: 26.9”



Switching to 20x9" Front & 20x11" Rear Wheels

0 .5” (12.7mm) wider front wheels require 10mm wider front tires.

1.0” (25.4mm) wider rear wheels require 30mm wider rear tires.

Require 255/35ZR20 front tires and 315/30ZR20 rears tires.

255/35ZR20 Diameter: 27” (.3” taller)

315/30ZR20 Diameter: 27.4” (.5” taller, requires speedometer adjust)

Offsets to maintain current outer edge (withour the current 15mm front spacers and 20mm rear spacers):

Front – 40mm (same as outer edge with 15mm spacers, 3mm more clearance inside edge)

Rear – 52mm (same as outer edge with 20mm spacers, 6mm less clearance inside edge)

So the question is: Will 9x20-ET40 front / 11x20-ET52 rear wheels extend to the same place as 8.5x19-ET49 front with 15mm spacers / 10x19-ET59 rear wheels with 20mm spacers?
