Id like to hear some opinions on the Nitto NT-01 tires. How are they compared to Azenis RT-615's? Im looking to go for the 245/40-18 front and 275/40-18 rear. Im thinking of mouting them on some Work Emotion CR Kai 8.5 +20 and 9.5 +20... or would it look nicer on 9.5 +20 on all four corners? I really like the concave spokes on those wheels.

 

NT-01's are a full R-compound tire with a 100 treadwear. The 615's are a street tire with 200 treadwear.

I use the NT-01's on my track/autcross set of wheels. They are grippier than the 615's but require some level of warming up. And like any r-compound after a few hundred miles you're practically running on slicks...very noisey, not good for street.

As for the wheels, if you run the 9.5's in the front with that offset use a 245 tire to clear fender. I ran a 275/18 on the front with 9.5 +22 and it rubbed...had to flare the fenders a bit.

 

Do they even come in those sizes? I have RT-615s and love them.

 

Great post! Thank you.

 

The RT-615's come in 245/40-18 which is perfect for the front, but they dont make anything close to a 275/40-18 for the rear. http://www.falkentire.com/rt615_sizes.html

Im tempted to try the 255/40-18, but i did that on my Nitto 555's and i think the larger diameter in the back tires shifter more weight to the front. It slightly threw the car's blance out IMO.

 

I'm running 235/40-18 in front and 255/40-18 in back. Balance is perfect, stock stagger is maintained and these tires actually run a bit wide; the tread widths are equivalent to 245 and 265 in some other brands. I love the setup and have not yet found the limits of grip on the street.

 

Cool thanks!

And i got mixxed up on my last post. I was thinking 255/45-18 on my old Nittos. I think i can live with a 255/40-18 though.

 

Just buy the tires already candy ***....

 

Hey, got any spare wheels i can mount drag radials on? I might need some for the track with the nice weather we are having.

 

The NT01's are definitely better gripping tires but if you actually look at their treadlife, it isn't meant for the street.

ST615's are awesome. I run them all around 265/35/18F and 275/35/18R.

 

No, I don't have extra wheels. Sold the stockers a while back because they no longer fit.

 

Cool, got any pics of your car?

 

Here are the pics of the old setup. https://my350z.com/forum/media-share/204539-pics-of-my-ppw-56k-no-no.html.
