I was just wondering what size tires and wheels you guys were running. I'm trying to get an idea what will fit, what will require a little work, and what will absolutely not fit. Seems like very few miatas are running anything wider than a 205 and I would assume that may be an issue as hp rises.

Assuming the same tire size and offset, does the front or rear become more of an issue to work around? What tire/wheel setup are you guys running and how's the fitment? I've been thinking about a 15x7 +35ish and some 225/45/15's, those should fit right??? If some of you guys have pulled off some 245+ tires I'd love to hear about the setup. Thanks.

 

Everyone runs 225/45/15s. There are no 245s in 15 in mass production. 15x8 is what you should run on a 225. This has been talked about in about a billion threads.

 

195/60/14s FTL :(

 

Just ordered 16x8 Enkeis with Toyo T1R 245/35/16 for my 90 today. After talking to Goodwinracing as long as I dont go too low it should fit fine.

 

225-50-15's on 6.5" wide 15" wheels clear all the way around on my 99. Well, I had to 'slightly' bend in the outer lip of the fender on the drivers side rear front fenderwell, as the tire would hit it in 1st gear with a 100 shot of nitrous.

 

15x9 225/45/15

 

195/55/14...way too small

195/60-14 Azenis suck much *****

 

205/45r16s...on some random 16x7 wheels.


I've got a set of 16x7.5 Kosei K1s, w/ 215 Falken FK452s waiting to go on though.

 

I am wondering why no one has staggered tire sizes (smaller front and larger rear). I remember reading an old magazine article on the British BBR kit where they said the front was something like 195 (so as to not mess up steering feel) and rear was 225 for traction.

I don't think the link works. The logic sounds horribly flawed though.

Didn't people learn from the mistakes that the Starion / Conquest set? Staggered set ups on non mid-rear cars tends to result in horrible understeer.

 

225/50-15 proxxes 4 on enkei 15x7

had to roll the rear fenders some and remove the front liners, that's with new FM springs, kyb agx shocks, FCM top hats and 2/3" spring spacers

 

Azenis FTW
205-50-15 on stock rims.
200 whp and they grip fine now that I got a torsen.

 

205/50-15 Nitto NT Neogen VR on 15x7 wheels. Just got the tires 2 weeks ago and so far Im very impressed with them. Handle really well in the rain and highway on/off ramps.

+1.

Ultimate street/track setup currently for the miata.

Thanks for the replies, if anybody knows what offset their running that'd be great to know as well. I'm guessing pretty much anything +30 to +40 will work.

I would think staggered wheels would work fine with a higher hp miata, but I'm not gonna be the one to try it out. They definitely aren't just a MR thing, most FR "sports cars" come with staggered wheels; S2000, 350z, Corvettes, Vipers, and every ///M car since the E36 have all come staggered.

Is there a reason that an 8 inch wheel (or even 9 inch) is better than a 7 inch for 225s? A lot of the S2000 guys run 225's on a 6.5 inch wheel, although they are a tight squeeze, I never had any problems wit it. I just assumed a 7 inch wheel would be sufficient. I hear so many people talking about how sensative our cars are to unsprung weight I was trying to keep as much off of it as possible.

 

link does work for me. Its a pdf so you may have to wait for a while.

pdexta is right, there's been lots of cars with staggered setup, most BMW's (FR engine) and almost all open-wheel track cars including F1 (MR engine) are this way.

I guess the advantage is lighter steering for non-PS cars, while the understeer can be cured by running a larger bar or spring rate in the rear.
