Upgrade from stock wheel help
I would like to go from the stock 14" rims on my 1990 Miata to a 15" rim. I don't want to have to roll/pull my fenders at all, I'm Not on coil overs so I am at stock height. I did some research and found some one say they have ran 15x7 (idk the off set) and they didn't have to roll fenders and if this is true what's a good off set. I also saw some one say 15x8 with +36 off set works.. can any one verify this? And if it's not true then what's a good size to run? I'm sure this gets asked all the time but any help would be awesome. Thank you

If you are 100% certain that you will under no circumstance want to roll the fenders, then stick with a 7" wheel. The only ones I will recommend are the Super Miata 6UL wheels. SuperMiata949 designed and built them specifically for our community. Major brands have ripped him off; I am a small business and know the frustration, hence my loyalty.
Call them and they will not let you down. |
Uh oh I wouldn’t have posted that...
15x10 is good for street use. |
On a NA 15x8s require camber and a roll... generally anyhow. 15x7 over +30 is safe, then run 195/50s or 205/50s :)

15x10 +36 with a 245/40-15. Slammed 93 LE. Fits great.

Thank you for the quick responses!! If a 15x7 with any thing over +30 works then a 15x6.5 with +38 should fit no problome.
|
A 15x6.5 zero offset should fit no problem.

why would you ever put a 6.5 on anything sport related is beyond me. I can see his tire rack page open now......

Goodwin Racing's website has a lot of choices in Miata fitment.

Stretch some 165s on those bad boys and air them up to 45-50psi to gain 2mpg. Rad.

Ok posting here to not duplicate the same thread. My car came with what I believe are some 15x8 (with 225 tires) rims. I am looking for some help in picking what's next based on:
Any tips? |
15x8 +36 fits everything. Ever. Without rolling. With 205/50. Good starter setup. Do that.
|
I've been told that the advantage to starting with 'cheap' i.e. not race spec rubber, so performance summer tires vs tires that are 200 treadwear just for class rules, is helpful because the tires give you more warning when they let up.
15x8's should be more than fine to start on. Gain experience on those with cheaper 205's, especially while you're still NA, and then move on when you feel the need. You don't need spec wheels because you're not racing spec miata. If you're trying to stay in class for autocross, you need to become best friends with the rulebook. |

Run an endurance 200tw tire for track use, RS4 is a great example of that. I've seen reports of 30hr+ track time, I'm up to 10hrs with a few Autox and a few thousand street miles, not anywhere near half worn. If you have coil overs (for clearance) and willing to roll the fenders you're doing yourself a huge disservice running anything but 9's and 245 RS4'S. |
That's like, your opinion, man.

I was leaning towards 15x9, but someone I met recommended to go with 15x7 (spec miata size) and from some reading on this forum I should also go cheap with tires, and learn on those. All these sizes and offsets are making my head explode... too much information!!
Any tips? |
Ok got it. Stay away from 15x7. So I'll be looking at 15x8 with 205/50 to begin with, possibly change later on when I get more experienced. I believe that's what I have now but they look awful. I will soon be having coilovers too, so ride height should change. :bigtu:

I do stand by my statement that performance pads and R comps will last longer than el-cheapo all season crap |
