Tires for my car
 

My car takes a weird size 190/65R390 I was wondering if their is an normal equivalent that I could use on my car since I am having a hard time finding tires?

Unfortunately the answer is no.

Since the tyre size is expressed as A/B/C where
A: width
B: profile as % of width
C: diameter of the inner rim

Usually the diameter is expressed in inches (like 14", 15", etc.), but in this special case is in millimeters. 390 mm = ~15.35 inches.
So if you want to find tires easier, you have to change your rims.

You can get different size tires, just go to the tire store and they will tell you your options. I like Discount Tires a lot.

But, with a different size, you cant only replace one tire, and if you only replace 2 you cant rotate with the other pair.

You can also try tires.com on the internet (Discount Tires Website) they have a large selection

Try Tirerack.com They've got a huge selection, and are pretty good on the phone. Good prices, too.

tirerack says my factory tires are 220/70 R 14 Though.....so i'm really confused...but the body tag on my car says the metric size and a bunch of normal sizes.

Hi Merker,

What size are your wheels? Are they the originals? a 195/65R16 would produce a similar rolling diameter to 220/70R14. I don't think identical, but similar. Or do you have a "space saver" spare and is it this you're taking the tyre size from?

I suspect that you have 16" aftermarket wheels fitted, in which cas you'd be best off going to a reputable tyre supplier WITH your car and discussing suitable tyre (and wheel) sizes with them.

They are the original alloy wheels that came with the car. I'll post what my body tag says for tires. I probably will just go to a tire dealer and pick their brain about it heavily. The reason I wanted to know a standard tire size is so I could buy tires anywhere I please and then get them mounted anywhere. The tires on the car right now are really really unsafe for driving and I don't want to push my luck.

Well, dont go by what the tires you have on their now say. Find out what size rims you have first. Then you can look at all the various compatible sizes for that rim. If you cant tell the size, go to someplace like discount tire. Have em figure out your rim and tire size possibilities. Then pick a pair ya like and shop around. You might have a wierd size tire on a normal size rim.

damn confusing metric tire shit ... WTF, there needs to be a no metric tire size rule, would make it a lot easier

I have no focking clue what size tire you need

year, make and model of car please Merk. (is this the Stang you've been having so much trouble with?) also, see if you can find out where your car was produced. by your location of Wisconsin, Im thinking your car was a Canadian model that was brought over to the states sometime in the past. Domestically produced vehicles sold new in the US always carry wheels/tires that are measured in inches. If your wheels are in fact original factory equipment, that suggests that your car was produced and originally sold outside the states, likely Canada, where they use the metric system.

Also, should you find someplace that tells you that you can mount a 15 inch tire on a 390mm (15.35 inch) wheels, DO NOT allow them to do this. While it is possible to get the tire over the rim flange, the bead will NEVER seat properly and what you will have is a catastophic tire failure waiting to happen. This kind of thing happens most commonly with 16 tires getting mounted on 16.5 inch wheels. Like with your situation, it is possible to get a 16 in tire over the flange on a 16.5 in wheel, but the bead of the tire wont ever seat properly - bad situation.

Best advice I can give you is to go to a junkyard and buy a set of wheels in standard (inch) size then go tire shopping. You can usually get a set of wheels at a junkyard for about $50. Look for a set of 15x7(or 8) off a similar car (be sure the car is the same as yours in terms of front or rear wheel drive). Once you have some 15 in wheels, get yourself a set of 215/60r15 tires, which is a common size with a lot of choices.

good luck

just checked tirerack.com

oe tire size for an 84 stang (not SVO) is 205/70r14

optional 15 in size is 225/60r15

optional 16 in size is 215/55r16 or 225/55r16



stang SVO in 84

oe: 225/50r16

I measured the rim with a tape measure and it seems to be a 15 inch rim.....I'll have to take an old tire off to double check.

look on the sidewall of the tires that are on the car. you will find the size on there somewhere. what is it? also, if you take a wheel off the car, you may be able to find its size somewhere on the inside. then you will know for sure what size the wheel is. it is usually expressed in the form of diameter x width (like 15x7, 16x8, etc).
