from what ive been gathering on other forums, people say 4.56 is perfect for an aw4 and 33", but they havent tried 4.88 so they don't know any better. the others running 4.88 say don't do 4.56, youll just wish you did 4.88, espically if a tire size increase is bounching around your head. so toss that 4.10 idea out of your head. going 60 mph on I5 or any hwy's i have to keep my foot in it to maintain speed on flat ground. I'm faster than a geo metero but even with a Banks torque tube, throttle body spacer, K&N and 2.25" catback on my HO motor it does not pull hard.
