I ran 33s ad 32s on highway with 5.29s for a few years. Really drivable and good mileage too. I usually broke 20 mpg after taking the speedo difference into consideration. You could load the thing up like crazy and it pulled passes in 4th gear no problem. You could push headwinds in 5th most of the time.
I think your 4.88/32" combo should produce similar results.
By the way bro, what did your hybrid build consist of? I'm sure you've posted it somewhere on here but if you could please?
no major detail if you don't feel like it, though . Appreciated
