Differences between a 225/70R19.5 and an 8R19.5
Posted by steven from sugar land, TX, US on March 5, 2007
Other than size and weight differences, will there be any fuel economy savings or handling or loading issues between a 225/70R19.5 and a 8R19.5? I am juggling these two sizes as both will fit and both load ratings stand up to my needs. What would be differences in fuel economy or handling? This is on an F550 that I use for delivery and hot shot hauling.
The 225/70R19.5 tire is a little shorter (by about 1" in diameter) and a little wider than the 8R19.5. All other things being equal, that should mean that the 225/70R19.5 tire would improve the handling but the fuel economy would not affected negatively. But, if the "delivery" type service you describe is local, the fuel economy issue would probably be insignificant.
