    Situation: 3 tires are half worn, one tire is brand new but is the exact same as the other 3. Is this okay?

    My problem is that I can't find another Kumho ECSTA HP4 in P185/60R14 to replace it in a pair. I had one tire get effed by a screw and it was irreparable.

    Is there any way to artificially wear the new tire or something?

    I don't see an issue but it might pull towards the new tire

    If it pull a tad, I'm okay with that. As long as there isn't a safety concern, I'm okay. I just don't have the money for a set of 4 tires at the moment. If I happen to find a second tire, I'll replace it on the same axel.

    it should be ok as long as you're not taking turns retardedly fast ;)
    for some reason the tires on my brothers minivan are ALL of a different manufacturer (they must've all had different wear at some point?), and the brakes were replaced with cheap brakes (they squeal so much...) and he hasn't crashed yet with mixed city & highway driving (note: not recommended for aggressive driving ;))

    What if I regularly drive at 90 mph and ignore traffic lights?

    Shave it down so they all match within .001"

    I heard you should *always* inflate to sidewall... :D

    Okay - this I'm interested in. How's that done? Is it even a significant difference? Keep in mind this tire is an EXACT match, it's just new.

    edit: BTW, it's already on the car... front driver's side. I'll drive around later and see how it affects my steering.

    Have you tried one of those shady used tire places?

    Be sure to put the new on in the back. Maybe leave it there after the first rotation too.

    Well, they do shave down tires to match, but I was joking with the .001"

    Can you afford another? While 3+1 isnt too bad. 2+2 would be better.

    I drove around a bit earlier. Everything seems fine... I'll just start saving up for a full 4 tire replacement. It's as simple as quitting StarBucks :p

    Ok first thing do you have a fwd car? Awd? I ask because you can do this but your drive wheels have to be the same diameter. Or else prolonged driving with two different sized tires can play hell with the differential in the car just put the new tire on a non drive wheel and you'll be good

    Rear wheel drive (Miata) and the tire is on the driver's front side. I'm still actively looking for another of the same tire :p

    Back in the day I have had all different manufacturers. I've even had a completely different size on one tire during a mid-way blowout on a road trip when they didn't have the correct size (and it was Sunday in the middle of nowhere). I used to simply buy used tires for cheap from a junkyard and throw them on when the old ones blew out or wore out. The only thing I would say is if it's unsafe, you will certainly notice it when you drive! The wrong sized tire came off as soon as I got back from the road trip, it had a pretty bad pull!

    Either way, if it really makes you feel better I think you could just buy another tire of another manufacturer so at least you have 2 new tires (same height on the tread). I don't think it matters too much. But that's just from my experience, the experts may have another opinion.

    It's an ongoing project on a college student budget... I bought it, then I had to repair the rain rail and fix a leak by the windshield. Then I got the unlucky flat tire, lol... Now I've got some kind of fuel and/or fuel vapor leak to deal with. Once all that is finished, THEN I'll worry about niceties, like sweet tires. Unfortunately, I have no idea how to fix my fuel vapor problem, so I may have to shell out some serious cash to a specialist. :(

    Check the hard lines under your car, they like to rust out. They are very nearly shot on mine.

    Feel free to PM me with any questions, I've been playing 'fix the broken miata' for a little while now ;)

    I was in a similar situation and found a very suitable replacement on eBay.

    You already were right to put the new one on what isn't your drive wheels so thats good.

    If the tread patterns are similar, you probably won't notice the different tire most of the time. BUT, in extreme conditions, ie bad weather, emergencies, and track days, you are a lot more likely to notice that it handles differently than if all the tires were the same. So be careful there :)

    PS: If it makes you feel better, I have one odd tire on my Accord. One day I went to go somewhere and the OEM right rear was flat because there was a puncture in the inside sidewall. No where was able to find the same tire and the rest of the tires were not close to replacement time yet, so I went with a similar tread by the same manufacturer. Seems to handle fine and haven't had issues. That said, if I still have this car when the other three need replacement, I will just be buying four new ones to match them up again. Also, the three original tires are V rated tires, this new one is the step one down from V, can't remember what letter that actually is.
