It seems that there will be option to have a 17" wheels on this truck. When I try to put one size larger tires on my CR-V there was lots of places on the net who discurage me from duing such thing. (posible problems with the all wheel drive.) Will this be problem on this truck too? Will the dealer readjust the spedo?
This is the only place I get up to date info on this truck, thanks for all your Threads!

The truck comes standard with 17" wheels.

Many people will tell you you shouldn't change wheel sizes but as long as the OD (outside diameter) is almost the same there is nothing to worry about.

We all know that if you go to a smaller OD you will be overgearing your car and will effectively have more low-end power (plus your speedo will read more mileage than actually travelled). The opposite is then true for going to a larger OD (undergearing, better top end, less miles).

I know there is a wheel size calculator on the net somewhere, I just always do the calculations myself.

For example on my Civic I have run 175-70-13, 185-60-14, 195-50-15 and 205-40-16 tires that are all within a few millimeters of OD. I currently run 205-50-15 race tires and 205-40-17 street tires (both of which are a little taller than stock) with no problems either...

As an example for your CR-V, stock tire size is 205-70-15, the OD is 668mm (by my calculations) say you wanted to go to a 19" rim... a 225-40-19 would have a OD of 662.6mm, which is actually a tad shorter.

Just did the math for a Ridgeline too, I calculate the stock OD (245-65-17) at 750.3mm, so for example (I'm not sure if these tire sizes exist) but a 245-60-18 (751.2mm) or a 245-50-20 (753mm) or a 245-45-21 (753.9mm) or a 245-40-22 (754.8mm) would be about as close as you could get...

Man am I longwinded...

The dealership that I am using is supposedly going to order some brushed aluminum 20 inch rims for some of their Ridgelines. Having an open mind, I am going to take a look at them once they figure out what to order.

I am going to ask them about the speedo issues and what kind of tires they are going to put on the 20 inch rims.

Even if you went with something that was 50mm taller or shorter (less than 2") your speedo would still only be out by 7%. So, in theory anything between 700mm and 800mm would be pretty safe.

I guarantee you we'll be seeing these in snoop dogg videos on 24's by Summer... A 235-40-24 would only be 797.6mm!
