Eddy had the same size tires on his and didn’t complain.
I've never had any problem with the tire size, of course it's the only tires I've had on it so I can't compare.
I easily cruised 65-70mph on I5 from San Francisco to Seattle (when I bought it) and only had hill problems before I realized that I had to manually down shift to third *before* bogging down up a hill. Since then I'm quite happy with the 2.3 -4 banger and these tires.
My friend has a 2006 AMG G500 and is frequently in the shop with electrical issues (windows, transmission, fuel pump etc...). Happy I have so little electronics. She will easily beat me from a standing start, but, I'll drive much further! Just can't figure out why no matter the engine size, 4,6 or 8 cylinders, the millage hovers around 13mpg.
