With >700hp on tap, I'm looking for more surface area.
275/30-19 is actually better for the TCS, assuming you're using 215/35-18 front tires. The 60 mm of "stagger" (difference in width, front vs rear) doesn't help the handling, though. As for the best fit on the rim, both 265/30-19 and 275/30-19 are usually approved for mounting on rims 9.0-10.0" wide, so either one should work fine, assuming your rims are in that range.I bought these tires for my GL57S rims and while they seem to work well (can't believe how well they worked in the wet considering) they seem a bit stretched across the rears. I am currently running 265/30R19 but notice that the 275/30R19 are on clearance. Any reason why these would not only would work, but possibly even fit better???

That's correct. The size of the contact patch is a function of the weight and the air pressure in the tires, assuming the tires are inflated normally. For example, if you inflate all the tires on your 3010-pound NSX to 35 pounds per square inch, the area of the four contact patches will total 86 square inches, regardless of whether your tires are wide steamrollers for the track, or skinnies for the rain.Keep in mind that a bigger tire size does not necessarily mean "more surface area" (contact patch or footprint). It just means different shape.
It should work fine. I assume you have 215/35-18 on the front? That's fine for the TCS with a 265/30-19 rear on a '98 NSX. And you shouldn't have any problems mixing the Asymmetric 2 rear with the Asymmetric front. Go for it!Tire Rack still lists the F1 Asymmetrico 2 in 265/30 19. Tread width is actually 10.6 in (slightly wider than the 275/30) and the diameter is 25.3 - so only 0.3 in smaller than the 275.
Seems like a fit. Any downsides? Any one used this size?
