jason the nismo wheels are 19x9.5 and 19x10.5. not that running 285/35/19's on your 19x10 will pose a problem.

Yeah, according to Bridgestone, they're good for 9.5-11 wide wheels so I should be fine with 285 out back. I'd probably go 275, but the sidewall AR on RE-11s is 30 and I don't think I want that low of a profile.

The front is what has me on the fence. I always read wider is better for grip so I want to go 265, but thinking about what everyone's posted, speedo being a tad off (I'm sure it's so minute that it shouldn't even be mentioned), being slightly lower and scraping going from a 40 to 35 (again, probably negligible since I'm on stock suspension), I think 245 will do. Either way, they're great tires. I'm sure I can't go wrong. Any other benefits besides wider contact area on the 265 fronts?

You do know that your speedo is more accurate with the bigger tire right? The factory speedo is off almost 2mph
