+40 is what I run on my 18s and I have no issues.The TireRack folks listed something like 35-60 as being doable, so I sure hope 40 is ok.
Seems like you may have a little bit of a backwards idea of offset. A +32 offset will actually push the wheel outwards from the hub more than a +40 offset. The stock offset of the CTR is +60 bringing it in even closer. For an 18 inch wheel that isn't known to have great caliper clearance, going with a +45 and lower should be pretty safe.But offset is what really matters, you can run a 18" wheel, but if the offset is too low it won't clear. That's why I was concerned about running 18x8 32mm offset so I ordered 40mm offset instead
I am doing the same thing , what 19" tire did you get with your rims and why? I am still stuck on thisI just went through this dilemma for my car. Ultimately I ended up spending more money and getting the R specific 19 inch Motegis with 53mm offset from tirerack with snows. The net difference in price vs higher offset 18s was around $500 depending on the combo selected. I wanted to maintain close to factory scrub radius and stance and just did not like the way most 18s looked with lower offsets/non meaty snow tires at stock height.
255-35-19 Vredestein Wintrac Pro. Cheapest “performance” snow tire they offered. That size was $170 cheaper for the set vs 245-35-19 of the same tire.I am doing the same thing , what 19" tire did you get with your rims and why? I am still stuck on this
The wheels are 18” x 8.5 with a 40mm offset.This is my year around set up for Michigan .. I am running Michelin Pilot Sport All Season 4’s . I had A3’s All seasons on my Mini Copper S and good for dry/wet conditions but just OK for heavy snow..my biggest concern is the limited clearance for the front lip ?? Who can comment on how the car deals with snow and ICE that is over 3 inches.. more concerned with ice ruts??
So with this car, and other FWD cars, there is a little trick which seems very funny to me, but actually makes lots of sense. From a stand still you will have more traction going in reverse than going forward.This is my year around set up for Michigan .. I am running Michelin Pilot Sport All Season 4’s .
