I'm looking to change tire sizes on my stock 16x7 rims (I think the stock is 16x7 on a 2004 Mustang 3.9L V6) from the stock 225/55R16 to 225/60R16. From what I can tell, the new size will fit since it has a rim width of 6.5-8.5.

My question is this. Only one pair of my tires are bald. The 225/55R16 tire on the front have a good amount of tread left. It seems a big waste to take them off now. Will putting 2 new 225/60R16's on the rear while keeping the 55's on the front cause any major problems?

There are no problems at all, the car might have a nose dive stance but no problem. Changing the diameter of the rear might throw off ur speedometer though.

I checked and that size tire would throw off my speedometer by less than 3 mph at 65 mph. I didn't know if the difference between the two sizes on there at the same time would cause the error rate to grow or shrink.

As long as the size difference isn't drastic you'll be okay.
If you were to go 225/50r16 in front and 225/60r16 in back the difference might be drastic enough to confuse traction control, but you should be fine where you're at.

I don't think the traction control will notice much if any difference as long as both rear tires are the same.
Anytime you change the circumference and or diameter of the tire you effectively change the gear ratio...although only slightly it does change.
Why are you changing to 60 series in the rear and not staying with the 55's?

Because for some reason, the 55 series tires are quite a bit more expensive than the 60 series. Not sure why. You'd think they'd be a popular size (and hence, cheaper due to larger production runs) due to them being the stock size for at least the 04 Mustang V6.

I ended up already buying the Solar 4XS sold on Wal-Mart.com for $56.47 each. The reviews on it seem to be good.

https://www.walmart.com/ip/225-60R16-98H-SOLAR-4XS-Tires/52943302

I have a Wal-Mart store credit card so that helped make the decision. It was between those and the Antares Ingen A1 for about $5.00 more. I chose the Solar which are made by Sumitomo Tires. The Antares is a good example of why I decided to go up to the 60 series. The Antares Ingen A1 60 series is $59.78. The 55 series, which is the stock size for my Mustang is $96.80. There's no reason I can see for that kind of price disparity. The 60 series uses more rubber since it's taller, yet it's cheaper.

As for ABS and Traction Control, I know I don't have Traction Control and I don't know if I have ABS or not. No ABS light comes on in my instrument cluster when I turn on the car.

Tires are one of the biggest things I would not cheap out on. Those are the only things keeping you connected to the road. But to each their own.

This tire seems to get some good ratings and is about the same price as the 225/60's....http://www.discounttire.com/dtcs/fi...e&rd=16&rc=ORSINT&cs=225&sortBy=prca&toggled=
Might throw your ABS off.

Unfortunately I'm disabled and on a fixed income of only $919.00/mo. It's a miracle I had the CC to be able to at least pay for the 2 tires over 3 months. I can't afford top of the line tires.

What's it going to cost for mounting, balancing, and stems?
On the brighter side, you probably don't have a bomb in your steering wheel, as many of us do.
And for what it's worth, ABS brakes were not mandatory for your car.

We understand that money doesn't grown on trees...next time you need something for the Mustang maybe post a wanted add here on the forum.
If you were about 2400 miles closer I'm sure we could have found a solution...although if you need help don't hesitate to ask here on the forum.

My ball joints (upper and lower) need to be replaced as well as the slide pins on my front calipers. The calipers keep sticking and I'm pretty sure the slide pins are the culprit. I have the parts, but it's a matter of getting the work done. Getting all the work done is something I don't have the money for. I can probably muddle my way through the slide pins and the tie rod end ball joint, but I don't have the equipment for replacing the other ball joint.

Maybe you could reach out to some of the people on this forum that live in or close to your area...look on the members list...and tell them you'll buy them a beer or furnish Ice Tea or whatever you can...and see if someone could spare some time to help you.
As I mentioned earlier...if you were just a little closer I'd pack up the truck with tools and give you a hand...I can't believe that someone living close to you wouldn't do the same thing...give it a whirl and contact some of the forum members. Ask Noodles76 if he knows someone close to you or another member here on the forum that could help...COME ON MUSTANG FORUM GUYS!

Guess I should update my address. I don't live in Dade City, FL anymore. I live in Spring Hill, FL. About 45 mins away from Dade City.

Last I checked, it was somewhere between $12-$15 per tire. It's another reason I chose Wallyworld. It's the lowest price and I could put that on my CC too. I was also able to cash in some of my MyPoints.com points and cover part of the cost of the tires and mounting/balancing/stems.

So....is the reason your back tires are worn more than the front ones....burning out are we:lol:
LOL, unfortunately no. Back before when I knew jack ***** about tires, I had a blowout on my right front. When I went to get a used tire to put on it, they were out of my exact size, but the "mechanic" said they had one that would fit, but it was just a little wider.

The problem was (now that I realize what the numbers mean) that it wasn't wider, it was instead shorter. He put on a 225/50R16 which screwed up the alignment majorly. I thought it was due to me hitting the curb and causing the blowout.
