I just picked up some Nitto NT05's for my G37 IPL with stock IPL 19's
245/40-19 front
275/35-19 back
Theses are the first set of replacement tires since the stock Potenza's.
I'm pushing just under 600whp and 500trq. The tires grip better for sure on dry pavement, but I still spin into 3rd gear for sure.
The tires fill out the wheel wells better and have a sick tread pattern!
Road noise is slightly higher. I notice the tires now, where before I jest heard my exhaust. And by the way I am at stock ride height.
