I have a pair of new tires for the car that are 178mm wide. However, the car currently has tires that are somewhat less wide ( by a few milimeters). Can I place the wider tires on the back wheels? Will this have a detrimental effect on handleing or safety?

I was told by the tire shop employees that all the car tires must be the same width . Also, where on the tire does it state the dimensions?

Perfomance cars commonly have wider tires in the rear and narrower in the front. Depends on your car and the wheels you have. The sidewalls have the size on them above the bead somethinig like 245/45ZR17 the tire is 245mm wide, the sidewall is 45% as tall as tire is wide, 17 is the wheel sixe in inches.

I always had L60s on the back (that's WIDE for you metric young 'uns)
Goes w/o saying that they were all rear wheel drive.
Guess the import types put wide ones up front???

seems to have worked pretty well for a while now

When I was growing up most of the guys cars had rear tires 2-3 times the width of the front tires.

Tire size is usaully in the p-metric format on the side of the tire ex: 215/65/16 215mm wide, 65% ratio width on a 16" wheel. Is the car front wheel drive or rear wheel? Check the actual sizes first; if it's a an all wheel drive car you MUST match up all tires and make sure they are relatively close in tread depthas well or you run the risk of damaging th all wheel drive mecanism.

SHouldn't make too much of a difference on a standard frot wheel drive car, but it might handle a bit differntly.


FWIW,

Awsome. Thanks. Does it matter that my car is a front wheel drive Toyota Corrola? Should the wider tires go on the front?

So next time I get my tires changed I shoud just tell the guy to put them on regardless?

178mm sounds wierd...Usually car tire width are divisible by 5.. eg. I have 255/45/17 in the rear and 245/45/17 up front

Make sure that the profile is exactly the same. If it isn't, the wheels will spin at a little bit different speed, which is know to fool the Anti-Lock braking computer and make the car shutter pretty badly.

Maybe its 175 then. I'm not exactly sure. I do know that they are both the same size and 14 inches tall just like my other tires. The only difference is that they are slightly wider.

I think he measured the tread surface instead of thewidth of the actual tire; prolly 185.


Ya, you can tell 'em to put 'em on, but serously, what's the actual measurments on the ires you want to mix?

A lot of the extremely high performance cars like Ferrari have much wider tires on the rear than in the front. Skinny tires on the front can be very dangerous, most of your braking is on the front wheels, too small tires just don't work for braking.

Got it.

Fronts are 175/65/R14 and rears would be 185/65/R14.

The car is a FWD Toyota Corolla.

Hell, when I was a kid it was noteworthy if any 2 tires on my car were the same width - and they would not necessarily be on the same end or side of the car.

Practically the same size...shouldn't be a problem

Listen to this guy if your car has anti-lock brakes. It's kinda important that brakes work correctly.
If it doesn't have anti-locks, it won't hurt anything for that little bit of difference in tire size. It'll look goofy though.

Profile meaning width or height or both? I'm pretty sure the car dosen't have anti-lock brakes since I can make it skid rather easily by slamming the breaks in wet weather.

The most important thing is circumference. The only way to get it to match exactly is to have the exact same profile (height/width/diameter). Find out for sure it doesn't have anti-locks - if it doesn't, the sizes won't really matter. If it does, you're much better off just getting the same size tires all around.

What year Corolla?
Link Posted: 12/29/2005 5:36:35 PM EDT
It's a 93 Corolla. The circumfrence should be 14 on all of them.

I'm pretty sure it doesn't have anti-locks being a `93.

ETA: I just checked - no anti-locks in `93. No problem using the tires.

That's some serious "redneck talk" right there.



If the wheels are stock for that car and the front size tire is normal to those wheels then 10mm isn't going to be a big difference in width...Tirerack has an online tire computer but the wider tire on the rear will probably add 6mm to the overall height of the tire since the rear profile isn't lowered to compensate.

But we are talking about an old Toyota Carolla grocery getter that someone wants to save a buck on...Not a McLaren F-1

On a 93 Corrolla it won't make any difference.

You might want the better tread in the back. Reason being, If you're going to loose traction in a corner (like hydroplaning or on snow), Your'e usually safer if you loose traction in the front. Then the car understeers (front wheels slide), you reflexively back off the gas or brake and correct the skid. If the car oversteers (back wheels sliding) you're more likely to spin.

I have a car in the garage with original equipment 16 x7" wheels in the front and 16 x 8" in the back. Factory tire sizes are 205/55-16 and 225/50-16. Want to guess what it is? I can tell you this, the handling is wonderful.

If you loose the back end, you'd better be Schumacher to catch it!.

Someone should tell Chevrolet, because my Corvette has 245's on the front, and 285's on the rear, from the factory.

Shit, my reaction to a spin is to scream like a little bitch. Do you have a Supra?
