Hey fellas, I'm getting ready to go get new tires on the Colorado in my signature. Stock tires are 265 / 75 R 15. I didn't care for any of the options in that size, so I'm doing what a lot of other Colorado/Canyon owners do with their tires - increase to a 31 x 10.5 x 15.
I know that the increase in size will throw off my speedo a bit, but will the increase throw off my odometer, which will in turn throw off my MPG calculations (trip miles divided by gallons to full)?
I know the increased weight will effect MPG's, but I'm curious about the size. I would try to use the "Miata tire size calculator site" but it doesn't offer standard size options so I haven't been able to figure this information out.
Also, if the increase in tire size does effect the odometer, is it possible to update the PCM with the new tire size so that it will reflect correctly on the speedo, odometer, etc.?
Thanks in advance.
By the way, I'm trashing some extremely cr@ppy Goodyear RTS's for a new set of Firestone Destination AT's. I'll report back with my impressions of the new rubber.
