Ill cut to the point, they are 13x8 Circle Drag wheels w/ M&H 22x9x13 slicks. Will these fit on the back of a miata with 1.8l 95' brakes? Hows the height? Will a 9inch wide slick even fit? I have AGX on FM springs........All help would be appreciated!

i think its more that 9in. my 225/45/15 hoosiers are about 9in inflated measured across. depending on offset it should fit. you might double check w/ the fenders

yuo making alot of power or what?

230 wheel hp on a dynojet at 13psi, hopefully 250 on 110 octane

nice... those launches is gonna take a toll on your clutch...

good luck w/ the tires

i think those tires are too tall, if you car is lowered. a stock miata's overall wheel diameter is about 18.5"

maybe if you run a 175/50/13 on bald tires! a 185/60/14 is about 22" tall, so you should be fine. what ET are those wheels?

cheesefries, LMK how those launch for you, i'm planning on going with a 22x8x13 next spring!

22"? hmm... maybe i did my math wrong. stock miata tires were 185/60/14, right? if not thats fairly close i think. sooo...

185mm x 60% (sidewall aspect ratio) = 111mm

according to http://www.onlineconversion.com/length_common.htm, 111mm = 4.37007874"

4.37007874" + 14" (wheel) = 18.37007874" overall diameter, right?

You forgot to multiply by 2 for the 60% height

14 + 2*4.37007874 = 22.74015748"

Right?

^^ you are totally right.

i completely forgot to take "both" sidewalls into account.

man... i feel like a total ASS!

 

[chrisnick]

i just know tires well enough in "common" miata sizes to get the total height. then i double check with the tire calc at m.net. :lol:
