I was looking over my front end today and noticed that my front tires are not the same size...

Pass is 185/60r14 and the driver is 185/65r14.

2 Questions:

- How bad is this for the tranny and drive lines?
- The driver side tire is almost bald on the inside of the thread. Reading, it doesn't look like there is a camber adjustment with stock parts. Would these tires being different sizes cause this tire to wear this way?? Anything else to check, or just get new tires?? The rest of the front end is very tight...nothing loose on the wheel...

It is a 93 civic EX....5 speed

i think the second number has do with tire width so the height is the same which i think makes it safe to assume your not kinda lop sided so the tire wear is just for another reason.. is your car lowered?
either way you still need another tire if its bald or if your broke as hell rotate your tires so it wont ware down on the same spot any more.

what the hell am i talking about its independent suspension

Change to same sized tires and get an alignment. Problem fixed. Shouldn't do any damage except to the tire.

Thanks guys...I just got this car as a commuter and after going though it today, I noticed the issue.

I am about 1 month out to have the money for new tires and I will have an alignment then. I am thinking I will rotate the tires until I get new ones. I was just worried I would damage the tranny if I keep driving it..but it sounds like I am just going to eat up my tires...

Thx again...

You are correct about the lack of camber correction stock. If the car is lowered you should pick up a camber kit, the money you spend on it will be paid back to you in tire life.
The numbers in the tire size refer to its width, aspect ratio, and wheel diameter. "185/65R14" means the tire is 185 mm wide, has an aspect ratio (that is, the width divided by the height) of 65%, and fits on a 14" rim.
The difference in tire size won't hurt the tranny or suspension, but it just isn't a good idea to have a difference in tire size or tread depth.

Stock tire size is 185/60/14.

It won't really hurt anything but the tires themselves if they are different.

But everything will work properly with the correct size.

And yes, as tmzcivic stated, the first number refers to width, and the second to height.

Just for the math....

185/60/14 has a sidewall height of 185x.60 = 111.00 mm
185/65/14 has a sidewall height of 185x.65 = 120.25mm

Which means your driver's side of your car will be riding 9.25mm (3/8") higher than the passenger's side (assuming no suspension compensation)...

So yes, this could be responsible for the driver's side tire wearing on the inside edge, as the car would be leaning to the passenger's side. It really does not take much to be out of whack for tires to wear improperly.
