stock Nismo
245/40/19 = 26.7 inches tall
285/35/19 = 26.9
275/30/19 = 25.5, WAY too short imo
275/35/19 = 26.6, good
305/35/19 = 27.5, seems like a monster truck tire to me
Looking at the Nitto website (
https://www.nittotire.com/passenger-...formance-tire/)
i'd suggest:
245/40/19 front (same size as stock nismo)
275/35/19 rear (just 10mm more narrow, close enough)
