When shopping for new MX5 Miata wheels and tires there are a couple critical issues to consider:
Weight. The Mazda MX5 Miata is very sensitive to what is called unsprung weight (which can best be understood as what hangs off the Miata suspension rather than what sits on it). We therefore strongly recommend that you use only light weight wheels for your MX5 Miata like those we sell here. Unlike other vendors who rely on overly optimistic wheel weights as listed by the wheel manufacturers, we weigh each wheel that we sell to verify the weight that we list! For that reason, some of our listed weights here are slightly higher than the marketing weight listed on the wheel manufacturers' websites.
Offset and Size. Offset causes a lot of confusion. Here is a simple explanation. If the rim is 6 inches wide, and the mounting surface of that rim (backside of the bolt holes), is 3 inches from either outside edge, that rim has a 0 offset. To the extent that a rim's mounting plane is offset from that zero position, that offset is measured in millimeters for Japanese cars. For the 2006-2015 Mazda MX5 Miata the factory offset is 55mm for the 17 inch size. Street users considering a wider stance but staying with stock width tires may consider offsets down to 42mm. For Miata owners looking to go wider than the factory 205/45/17 MX Miata tire size, we suggest our many 48mm offset choices in widths of 7.5 and 8 inches for street use, or autocross or track work. Our 45mm 18x9.5 Enkei RP-F1 is intended as a race application only. Please contact us if you have any questions on appropriate MX5 Miata wheels and tires for your intended use.
MAX SIZE. Folks ask every day what is the MAX size they can install on the 2006-2015 MX5 Miata without rolling fenders? The max tire size that fits in stock MX5 Miata fenders is 235/40/17. Note that offset is critical, 48mm to 50mm choices get that 235/40/17 under stock fender lips easily, choices that are 45mm offset usually need some fender lip roll. Thus, our popular autocross 17x9 Enkei RPF1 with 45mm offset requires a fender lip roll for 235/40/17 or more tire (STR customers often using 255mm wide tires but that requires lips rolled up flat inside). Thus, the limit without fender flares is 255mm, we run as much as 285mm and 295mm tires using our fender flares which are available on this site.

I wanted to thank you for the excellent customer support,the smooth transaction, and the quick delivery of my Enkei RPF1 16x8 wheels. I would recommend your company to anyone interested in good old fashion great customer service. Thanks again and look forward to doing business with you again in the future.
I red'all the parts in the order I placed and installed them in my car yesterday.
I am beyond happy. The install went without a hitch. The results were fantastic. The new brakes track straight, make no noise, and stop the car authoritatively. The new rotors look pretty cool, which we all know isn't all that important, but having 6 women offer to bear your children, because your car looks SO cool is a good problem to have.
Thank for great products and service.
