Hi All:

I am planning on getting new 18 wheels.

I choose OZ Supperlegera 18 x 9





Now, My question comes to Tire Size.

This is the Miata Tire Size Calculator

This is the first alternative compared to Stock with 255 40 18



As you can see, it is almost a perfect match in terms of circumference. Also the MPH are .1 over stock.

This is the second alternative compared to Stock with 245 40 18



As you can see, it is almost a close match in terms of circumference. Also the MPH are .6 under stock.

I want to use 255 40 18 S03 with 18 x 9 wheels. My only concern is that if this setup will work in the front without rubbing. I am sure it will work in the rear.



S03

Can anyone shed some light in making my decision?

Thanks,

Everett

Damn. Those are pretty nice. I don't think 10 mm will make a difference. What is your application? What are your wheel offset options?

Everett

Hi!!

The application is street use. The Offset, I am not sure. I am planning on purchasing from Tire Rack and they send the correct wheel offset according to the vehicle application.

There are people who have put 275/35/18s on the front with no rubbing...but these people also have stock suspensions (i.e., not lowered at all)...if you buy the 18x9 from Tire Rack, the offset will be +55...based on that and a stock offset of +50, I'd say you'd be fine with 255s in the front...

Thanks for the tire suggestion!!

What is the price for the Sport 2?

Thanks,

That is just tirerack's just to see "photochop". I'm sure they will look alot better in real life.

after 3 months research here's what i have done to modify my cars appearence and performance

WHEELS (racing Hart,F-10)
front: 19/8.5
rear: 19/10

TIRE
front: 245/35/19
rear: 275/30/19

BRAKE

I have also replaced the front and rear sway bar and springs and fitted a new exhaust(racingbeat) .

Yes, post pics!!

I love those Racing Hart F-10's. I would love to see them on an 8.

I don't know about the 255's, but they (tirerack) had a special on 245/40/18's of the PS 2's that made them essentially equal in price to the S03's, BF Goodrich Comp TA's KD's. At that point for better wet traction, tread life, & tire noise I would get the PS2's.

Question: What's the tradeoff between 18x8.5 to 18x9.0? Is it just a matter of whether it will fit? I'm about to order the Volk Racing SF-Challenge and have decided on 18s, but apparently they don't come in 18x8.5 (what I wanted), so the decision is between 18x8 and 18x9.

max_rx8

18x8 & 18x9 would work great and also look good, tires for this size are 245/35/18 & 265/30/18
On the rear if you were to go any bigger up to 18x10 you would have to replace the spring and the sway bar so the wheel would not rub against the quarter panel.
the size you are after now, you dont have to make any replacements.
