225/45/18 stretched on a 18 x 9 wide, stupid or just pushing it?

Wanna know if the stock tire stretched on a 9 wide is pushing it and doable, or just stupid and can lead me to trouble? I have a set of stock tires just sitting here, figured I might as well burn off the thread on them if i can.

meh, if they're expendable, go for it, I had 225/35 on an 8.5 for a while, so you should be fine.

It might work just fine, but it WILL look shitty.

You're better off spending an extra few bucks getting wider tires than chancing the stretch

Don't do it. Even Zumn is telling you not to be like him and stretch tires.

I have stock sized tires on 8.5 inch wide rims. Personally i think it looks great, but I probably wouldn't want to stretch more than that.

You're running 225s on a turbo 8?

if that's what the stock tire size is, then yes.

yeah, 225 is stock. Do you get grip problems?

Not really, my tires have pretty good traction actually. Works fine for the street.

I might get 235 or 245's next, but I don't know...I don't want really beefy looking tires. Plus the 225's fit my budget better at that time.

i know a guy running 225s with a 450whp dodge neon. and apparently that is the max tire width he can run. car choice fail. lol. anyway...

245s are a big performance difference rex. i can understand about budget though.

See my sig for my set up. No issuse what so ever. Been running this set up sence last summer.
I'm going to get better tires soon but I have no issues with the stock tires. I will lose some grip on turns but thats norm for this car anyway.

I have been running those on my 18x9 for the last 4000 miles no problems. I drive hard a little and have had no problems. Disregard the gap in the rear. The S-tech where not installed in the back yet.

Check sig for setup

It's not really my personal preference as I'd prefer a 245/40 on a 9", but Emilio from 949Racing runs a 225/45 on a 9" for his Miata for racing applications. 225/45 on 9" has been reported to have much success for the Miatas and are faster than 225/45 on 8" by a noticeable amount. Having said that I'm sure a 245/40 on 9" is even faster, but the NA/NB Miatas can't fit that without fender modifications.

If you really must, I'd say go for it.

I personally like the geometry of the car with the nose lower than the rear... it looks really aggressive. Sort of like you are constantly hard braking into a turn.

it's OK for the purpose of using up the tires, but switch to 255 - 275 size for the replacements, the idea of going small on tire size to stiffen the sidewall is a bogus misconception and the sizes noted will typically fit without issue if your wheels are in the proper offset range
