So you're going to tub the inner fenders front and rear, then? Because that's what it takes to put a 24.5" tall tire under a Miata.

 

Where are you getting 24.5 from? Wheels are 15s, sidewalls are 50mm (just under 2 inches, so 15+2+2... that's 19 by my count.
And if it takes tubbing the inner fenders, that's what I'll do I guess, but I haven't notice any rubbing other than the firewall (not saying I'm 100% sure it's not happening, but the firewall is the only spot I noticed).

 

 

not sure if he's serious

 

Dead serious. If I'm wrong, feel free to let me know why... that's why I'm here, obviously I'm doing SOMETHING wrong, or this thread wouldn't exist...

 

Yeah it doesn't work like that dude. Just pull up a tire calculator online or go out and actually measure your wheels with a measuring tape

 

Just did some research on tire sizing... always assumed that since the width of the tire is millimeters, the sidewall would be as well... learned something new

Well, if tubbing it is what it's gonna take, I guess I'm in the market for a new welder. The flux core welder I've got now isn't gonna cut it for structural welds :/


Thanks for all those who have helped thus far (even if you weren't meaning to, and just came in to laugh at the noob, it got me pointed in the direction I need to go, haha). Guess I'm pretty much done with this thread unless anyone that's got experience in making wheels this size fit wants to post what they did to make it work (some pictures would be much much appreciated).

 

For reals? A Slow Adult armed with a Flux Core welder and not a shred of a Clue, who is literally incapable of *measuring* a tire, is here talking about somehow relocating the ******* shock towers, on his DAILY DRIVER, so that he can run the retarded steamroller looking wrong sized tires he bought by mistake...?

Seriously?

Here's an idea; Leave the welder alone, and put away the Sawzall FaeFae. Just buy some goddamned /45's.

 

Google "tire aspect ratio", or take a tape measure to your car. Stock tires are 22.7". The tallest you can reasonably go is 23.0" (205/50). 225/45s are a smidge shorter (22.9). 225/50s are 24.0", which is too tall. Yours are 24.25", which is way too tall.

You haven't actually pushed the car hard yet, then. As I said before, the 205/50s and 225/45s polish the tops of the inner fenders as is. Putting a taller tire in will just make that small interference into a large interference.

 

You mad bro? Cuz I analyzed your post, and after extensive research and consulting, it appears as if you are, indeed, mad.

If you're going to insult me, at least take a second to calm down, make sure you've read everything correctly, and come up with a response that makes at least a LITTLE sense...

Just to clear up the things you seem unsure about so you can sleep a little better tonight:
I'm fully capable of measuring a tire. I misunderstood how they came up with the number for the sidewall profile, and thus didn't use the correct equation to figure out the real size.

I never said anything about relocating shock towers... dunno where you came up with that.

I didn't buy these tires by mistake. This is the exact size I wanted to put on here... if you don't like them, that's all you. I like them... that's why they're attached to my car right now
That being said, I WILL be buying some thinner tires for the front (mentioned that early in this thread), but for now I'm going to do whatever I can to make these work (also mentioned earlier in this thread).

Now let's have a nice big hug, take a couple shots, and once you've calmed down we can be friends again (bffl? I think so!)

 

Thanks man, I understand now. Looks like I've definitely got some work ahead of me, but it'll get done regardless of all the haters

 

Good luck.

 

Nah Brah, I ain't mad. Incredulous maybe. But yeah, it was late, so I guess I misunderstood the part where you had no clue about calculating aspect ratio resulting in buying tires with a distinctly agricultural look to them. After re-reading this thread I see the error of my ways and how I clearly underestimated what you and a Buzz Box welder can accomplish. (I didn't catch the "went at it with a sledgehammer" part, which is of course the hallmark of fine craftsmanship, isn't it?)

So, really, sincere apologies my clearly Clue Possessing new BFFL. If you're anywhere near Florida I'd like to volunteer the use of my Plasma Cutter and complete Machine and Fabrication shop for this little clearance cutting you plan to do. I'll provide the beers and take the pics as long as my guys can hang around and watch. I mean, even though we do fabrication and customizing every day, we always enjoy watching someone more knowledgeable than us work; never know what tricks one might pick up.

I'll fire up the Buzz Box for you; we'll Par-Tay.

 

I've only seen one other dude run these tires on a Miata, was "Marlon The Great" or whatever his name is on ClubRoadster.

No real details on what he did to make it work, or if he actually ran the car like that on the track. He DOES do track work with it, but i'm unsure how serious, if the car is fast (doubtful), or if he actually drives it hard.

 

OP - if you're going to put smaller tires on the front, then you're also going to want to put smaller tires on the rear. The only conceivable reason to run different sized F/R tires on the miata is if you only plan to drive in a straight line; otherwise, the "performance" aspect you're so adamantly trying to achieve is pretty much thrown out the window.

 

So I spent a while looking at tires this morning, and I'm thinking about going for some 225/45 Hankook Ventus R-S3 when I can afford them (anyone want a set of R888s? xD). That should make the diameter about an inch and a half smaller, and there will be more strech as well... any input?

 

 

Angle grinder with a cutoff wheel and engineer's hammer. This is the only way... Oh and longer bump stops.

 

On the bright side though: At least this guy is rocking some seriously meaty tires and not some uber stretched club roadster hard parking fgt look.

 

Smaller tires.
