The P stands for passenger tire.
THe 176 is the width of the tire in millimeters.
The 65 is the height of the tire as expressed as a percentage ratio to the width so in your tires' case they are approximately 114 millimeters from the bottom of the tire to the rim.
The R is a speed rating on the tire--that is the maximum speed at which that tire can safely be operated. As I recall, R series tires are rated to something around 106 mph. This is mostly a function of the tire's rubber compounds and design and its ability to dissipate heat--higher speeds generate more road friction and more heat. A Y rated tire, for example, is designed to stand up to 186 mph.
The 14 is the rim rize.
As to changing your tire size, yes you can of course. Generally you can put one size wider on your rims, say a 185 series, though of course a 185/65 will be slightly taller as 65 pecent of 185 is 120.25 mm and so a little speedometer error will be introduced.
You can also change the speed rating, going up to any number of ranges incrementally S=112 mph, T= 118 mph, and so on. However, if your car's top speed is under 106 there would be no real reason to do so, as higher speed rated tires cost more.

The actual width 175? Go to tirerack.com the web site allows you to look at different tire and wheel on a picture of your brand and color car. COOL. If you need to talk to a tire person call toll free# they are helpful.
BACK TO THE QUESTION, How many times a tire wheel assembly turns in a mile is important for the Speedometer to read correctly. Yes you can change the width of your tire. Meaning of the three # separated by /. 175 denotes width/65 aspect ratio height over width/ and R14 rim diameter. Sounds like lots of small cars out there. Owners want a little more"BLING" did I say bling! chrome rims and new tires. Buy the very best tires you can afford because tires are the only contact to the road you have.

P = Passenger tyre.
175 = 75 millimetres across ( wide).
65 = 65% ratio. That is, height of the tyre ( from the inside of the tyre to the top of the tyre ( as you look at it from the side ).
R = Radial tyre.
14 = 14 inch diameter.
You mgiht be able to change it but you have to check that it won't upset some things or else you'll get an incorrect reading on your speedo.Consult an owner's manual or ask a similar question here.

It means that your tire width is 176mm, the height (sidewall) is 65% of 176mm (114.4mm) R means radial and the wheeel is 14". Generally the rule is every inch you go up, you have to change the Sidewall height by 10%, so to go up to a 16" wheel, the code would be P 176/45/R16. You can keep the sidewall height, but this will mess up the speedo.

the previous answerer showed the dimensions and there are only certain things you can change.
You must keep a 14 inch tire with that rim
you can put a slightly wider tire but you would need a lower aspect ration tire, for example 185/55 but this would mean a harder ride but slightly more grip and probably sharper steering. Your speedometer reading may also be affected.

P = passenger
176 = tire width in Millimeters
65 = the side wall height as a percent of the width
R14 = 14" diameter wheel.
You can change it but it will effect the handling, ride and speedometer.

iwingameover has a good answer, also, if you change your wheel size, say to a 15 inch, and you get a tire with a smaller sidewall, like a 50 or 40, it would be similar to the size tire you have now and wont affect your speedometer to much if at all.

You should have bought the wheels and tyres from a reliable supplier then you would have got the correct tyre size 235.35.19 to keep the overall diameter and load ratings the same. Your insurance company could query the undersize tyre if you have an accident. Why didn't you ask the question first before you bought the wrong combination?

i believe it is 176 mm across 65% racio which is the hight, and 14 is the weel size, r means radial.
