The Honda owner's manual states not to install tires that differ from those that came stock (225/60/18), as it could effect VSA function. I am considering the installing 236/60/18, as there will be less revs/mile (so slightly improved gas mileage) and possibly better handling. In the winter, I use a 225/70/16 winter tire (mounted on some old Prelude rims), which are slightly less circumference than the 225/60/18, and they seem to work just fine; no VSA issues, and they grip very well (not so great cornering on drive pavement, but tolerable) on packed snow surfaces. Also, I've increased tire width on a Honda Pilot in the past with no issues. Thoughts from all the wise and noble Crosstour owners?
