that Nissan approves of a size replacement for the rear 245/45/16. They say that 245/50/16 will fit. Search for that size and you will find more brand choices out there. I settled on Michelin's off brand Riken Raptors because I plan on wearing them out real quick until I can get more camber adjustment with aftermarket parts (adjustable A-Arms & tension rods) Tip: DiscountTireS.com has Rikens for around 80.00ea. DiscountTire.com wants 110.00. After I pointed this out, DiscountTire matched the internet site (DiscountTireS.com) price. They said that the site was a competitor and I think they're pissed at the name similarity and want your future business. Good customer service IMO. About the tires (Riken Raptors), the Mustang crowd loves them...we'll see how they perform. Like I said, I've got camber issues. I was going through Dunlop 8000 about every 10,000 mi. on the fronts and that's with new stock springs/shocks & urethane tension rod bushings. We'll see.
