I am trying to decide between 18" wheels and 20" wheels. If i get the 20's, what size tire would i need? Thanks

Aaron

 

The 18 inch 245X40 are best and are better ride and cheaper then 20 inch.

 

please, please, please do not put 20's on an rx-8..

 

Would 20's look bad? i always thought they'd look awesome on an rx8. what size tires are best for 20's though just in case?

 

READ the wheels and tires section you will find what you are looking for (aka the "will it fit" thread)

 

The closest to the factory 225/45/18 is 245/30/20 (http://www.miata.net/garage/tirecalc.html). But as has been mentioned...PLEASE don't put 20's on an RX-8.

Not a Cadillac...

 

Just be careful. You have to realize there is a bad downside to bigger rims. I have 19" on my car right now, & the ride is a good bit stiffer. with 20" I bet the tire looks like rubber bands & the ride will be ridiculous.

 

i would never put 20s on my car. but i do have to say that 20s fill out the wheel wells much better than 18s.
