Hey guys, i just ordered a set of Rota P45Rs in Hyper Black for my black 350z. Going concave all around... the offset that they had available was +20 the rim size is 18 x 9.5 all around. Im planning to run 255/40/R18 in the front and 285/40/R18 (1.1%increase) in the rear. Do you think with +20 it would look flush? Should i have waited and gotten +30? What is the difference?

 

The difference is 10mm, the +20 will be ok. I'd go 265 front and 285 rear, or 275/35 front and 275/40 rear myself.

 

+1 , Scott couldn't have said it better

 

I just ordered the P45R royal gold. Can't wait to get them. For tires 245/40, 275/40

 

You intend to put a 285 mm tire on a 9.5 inch wheel?

 

Not sure why you sound surpised?

 

+20 will look kinda flush. im running +10/+8 offsets and its perfect. not hellaflush. the +30 offset would have not been flush at all. it would have been the opposite. do you know how offsets work?

 

I kinda have a guess, but i never understood it fully. The 285/40 is currently mounted on the rim now and it looks HUGE... it feels like way too much rubber for that size of the rim. let me see if i can post a pic...

 

Here is the pic... just looks like a crap load of rubber, im hoping once its on the car, it will look more subtle..

 

Thats a big tire!

 

Mine are +12 front with 255 35 18 and rear +20 285 35 18 rear.

 

The 285/40 is alot of tire, but it's going on the back of a sports car. The rear fenders of the Z require a bit more wheel/tire to look filled up anyway. Get them mounted and post a pic. I bet it will look just fine.

 

this is how offset works. it denotes where the back of the hub is in respect to the centerline of the wheel. in layman's terms, the higher the offset, the further the wheel will be inside the wheel well ; the lower or negative offset, the further out the wheel will be. in not sure about other models, but the stock 03 track model wheels have a +30/33 offset

 

This is +12 & +20







255/35/18 front 285/35/18 rear rims are 9.5 wide.

 

First response was on golden

 

So why the different heights and what brand tires are you running? Looking for a street/track setup. Thanks

 

I like a wider tire. If you want a street/track set-up, one can go with Toyo R888 or RA1 tires, Dunlop Star Specs, or others, but those are the ones that I run. For this dual functionality, I'd likely run the same aspect ratio front and rear as well (i.e. 275/35 all around) so that I could rotate them.

 

I'm going 265 all around as soon as the pos Nitto 555s I bought the car with are near worn out.

 

Wheels are finally on the car. What a pain in the *** it was to roll the fenders. Yes you heard it right, i had to roll the fenders because the tire was too wide... 285/40/18 with +20mm offset was rubbing on every bump. Anyway, its all better now, i think the cars looks really nice now. Check out the pics...

 

Looks good. Glad that worked out for you.
