Hey Jim... these were direct fit at my config as follows:
18x8.5 & 18x9.5 both with 35mm offsets. Only needed hub centric rings.

Tires Conti SureContact RXs 225/40zR18 92Y XL & 265 35zR19 97Y XL


No speedo issues, ive clocked via speedo gps app. Higher sidewall comes within 1/4 inch of previous rear 19.

The Motegi Racing MR135 could be done with a standard staggered 18/19 though, no worries.

Roads here are utter ****, and i went to a higher sidewall in back to try to give myself a fighting chance in hell of not wrecking my wheels. Of course after i dropped 10 bags of cold patch on my street (need to drop another 20), and switched to 18/18 set up, the city decided to repave the entirity of the adjacent main street... sadly not mine too tho. Unlike chicago proper, you cant send the city a bill for wheel damage reimbursement around here.

Considering a set of staggered 18/19 HyperGrams from Konig as an alternate for next summer, with faster rubber, and keeping these as my winter only set if we get any traction with city repaving a couple more main problem spots between me & the freeway on ramp 😏
