So my OEM R-Sport wheels are 19x9 up front and 19x10 in the rear. I test fitted 18x8 winter wheels which cleared the brakes, but they are non-staggered, wondering if that will impact stability or the suspension setup in any way. I used a wheel calculator which said I would have 8mm of positive radius scrub. This is only for winter so I don't mind sacrificing some handling prowess but the concern is that if a non staggered setup will affect the suspension geometry or cause any instability.
TIA.

 

I just put 20" x 8.5" TSW wheels all around on my XJL supercharged. I talked to guys at Tire Rack, Discount Tire and TSW wheels. They all said the size I put on was fine. Have been on for a few days now. Rides like dream, no issues. I would check on just 8", not sure how small you can go. Mine has 20" x 10" front, 20" x 9" rear, most likely what yours is also.

 

Oh sorry saw you said you had 19" factory. I would call a few places to make sure you'll be fine. Or maybe someone with more knowledge will speak up.

 

Yep, thanks, hopefully some others on the forum can chime in as well
