I'm sick of looking at my Motegi's...I also did a little research about size/ heights.
I'd like a set of Nickel 15x8 6UL's, but (no offense to you cause I like the 6UL's) everybody has them. They are nice, and for the price, they're a great wheel.
I asked Emilio at 949 about fitment issues on my car ('99 with FM springs) with a 225 tire. He said a 225/45/15 would fit no problem.
I asked Brian Goodwin about them also, and he replied with "Folks use a 205/50/15 or 225/45/15 on those 15x8."
The reason I want a 225 is because I want my car to hook when I launch it, and it usually works out that the wider the tire (the more surface contact) the more traction I will get on launch. (Unless I'm missing something).
The reason I want a 45 series tire as opposed to a 50 series is simple. Everybody runs a 50 and I don't know why. The 45 is a lower sidewall which means less sidewall flex, and also a lighter tire due to less material.
Let's begin the wheel debate.
I like the 6UL a lot, a real lot. If I didn't go with Nickel, I'd go with Black. I also like the spoke wheel look such as the Konig Flatout.
Then I thought about it. Why run a 15" wheel? What's the reasoning??
I remember I weighed a wheel and tire from my car on my bathroom scale and it was like 33lbs?
My wheels are 16x7 Motegi's with Toyo Proxes 205-45-16's on them. That means it has an overall diameter of about 24".
According to tire rack, one of those tires is supposed to weigh like 21 lbs? There is no way my wheels only weigh 12 lbs.
A 15" 6UL with 205/50/15's...let's use the same Toyo as mentioned above.
The tire weight is the same, but the diameter is 23".
I don't understand what is gained?? It is a wide wheel, but the sidewall is also higher, but now the car will sit 1/2 lower?
A 225/45/15 tire would end up being the same 23" overall diameter. This would make my car sit 1/2" lower than it does now. Is that the gain the everybody is talking about?
Can you explain to me what is going on that I'm not seeing?
The offset of a wheel is the distance from it's hub mounting surface to the centerline of the wheel.
The factory offset of a 90-05 miata wheel is 40mm.
The 15x8 6UL comes in a 36mm offset and weighs like 12.6 lbs.
The 15x8 konig Flatout comes in a 25mm offset and weights 12.4lbs.
Then I found the Konig Helium in Black.
Miata Performance Parts : BLACK Heliums, 40mm Offset--11.4 Pounds : 16x7
It's a 16x7 and it only weighs 11.4 lbs. I really dig these wheels, and I could be a cheap-o about it and craigslist my motegi's and put my current tires on these new rims.
I don't like how the Konig Flatout with a 50 series tires looks...it makes the car look like it's sitting on big tires, in my opinion.
Miata's with flatouts: and 50 series tires:
So what do I do? Buy the 16x7's and keep my 205/45/16 Toyo's because I drive it on the street? Or buy 225/45's and 15x8 6UL's?? Or Konig Flatouts?
This drives me nuts...I want new wheels, but I don't want to make a purchase regret.
