I'm going to buy a new set of summer tires for my truck. I also plan to buy a new set of rims at the same time, so, that I can leave the studded snow tires on the factory rims. Then I won't have to to make an appointment, or wait in line, or pay $75 every Fall and Spring to have them mounted.
Because I'm not limited to the original factory rim size of 16": I could choose increase the rim size, while reducing the aspect ratio of the new tires, in order to maintain the same overall size of the whole wheel. If that would be an advantage, of course? I've noticed that lately, all of the newer versions of my same make & model truck, now come with 17" or 18" rims, and tires of lesser aspect ratio. Wonder why?
So, a 265/75R16, is equivalent to a 265/70R17, which is equivalent to a 265/65R18. They are all approximately the same height and width, only the height of the sidewall is different to make up for the different diameters of the rims.
I don't use my truck "off-road", unless you count the Haul Road or other gravel highways. So, what are the advantages/disadvantages of these different combinations?
PS - What brand of tires are the most durable, while providing the best puncture resistance from high-speed gravel road driving?
PPS - Aluminum or steel for the new rims?
