If you put on different sized tires, then its up to you to have the calibration changed. Personally I'd just check the speed with a gps and remember the difference. Probably one to two mph difference.
Are you kidding? There's no way warranty will cover that. Why should Honda pay because you decided to change tire sizes?
What you are doing strikes me as weird: changing to a wider, narrower tire?
? For use as snow tires?
? To avoid buying tires when some are available (or steal-able) for free?
In any event, have you considered that you probably will not longer be able to claim original miles or vouch your car as “unchanged odometer” possibly reducing it to salvage status or uninsurable at normal rates.
cahanging things will probably " void " the warranty
From 195/65-15 to 205/65-16 ... Does the calibration... Does it cover by warranty my car has warranty or would i have to pay? This will be done at my Honda local dealer
