Question about tire size!!!?

The tires on my nissan altima need to be replaced due to an alignment issue [which is being fixed at this moment]. The tires that are already on the car are all 16's but all different brands. My boyfriend just bought 2 16's to be put on the car by the repair shop but they called me today and told me the tires he had bought weren't the right size.. but they're 16's..??! My boyfriend used to work for a company like Mr. Tire and he says that as long as they are 16s it shouldn't matter; that they'll do. I'm not sure of the technical size of the tires he bought or the size of the tires on the car [so many numbers.. it confuses me! lol] but can anyone help me? I have no idea where to start and want to see if my bf really does know what hes talking about. LOL|||Start by looking at the door frame for the tire size and inflation chart.





The chart will give the recommended tire size:


Example P245/70/R16 this breaks down as follows:





P245 = overall tire cross section.


70 = aspect ratio the higher this number the taller the tire is compared to the width of the tire.


R16 = the rim size in inches of the rim the tire must be mounted on.


There are many different overall size combination's in each rim size.





Unless custom wheels have been installed you should choose tires which are either the same size as recommended on the tire size chart or one size larger (10 points ) on the first set of numbers. you may also go up or down up to 10 points on the second number.





If the tires currently on your car are R16 size tires and the chart specifies R15 tires, that indicates that custom rims have been installed - in that event you need to go to a quality commercial tire shop where they have charts which will guide the selection process.





In any event both tires on either axle - front or rear MUST be the same exact size in all respects and for best handling on most cars all 4 tires should be the same.|||tell them to put the tires on the car its cool...i had the same type of problem before|||Your boyfriend's a troll. If the aspect ratio (Hah! Ask him about THAT!) doesn't match front-to-rear you'll wind up in the weeds because the front and rear tires are rolling at different rates. A very small amount of knowledge can kill you if you think it's enough.|||Well to start the recommended tire size is in the owners manuel or in the driver side door where the air pressure specs are the width and side wall numbers are very important to how the car rides and if the tires fit properly for instance the first number in a tire size is the side wall the higher the number the lower the side wall the second number is the width and the last is obviously the the rim or wheel diameter. Have your boyfriend or the shop get you the exact tire.|||The size of your tires are written on the tire or you can go to your car manual or to www.tirerack.com online to figure out the exact configuration for your tires. Here is what you need to know:








Size


16 is the wheel size, you will still need to take into consideration the section width, sidewall aspect ratio and tire/wheel diameter. (long story short go to tiretack.com, select your vehicle type, model and year and they will tell you everything you need to know.





Speed rating - depends on car type but you would probably be S or T





Load limit - cant be less than your car manufacturer specifies but can be more





Temperature rating - i would go for AA whenever i can





The information to look for on your car looks like this: Size: 205/65R16. Use that to match the new tires your boy got.





I just bought my first tires myself and i googled tire 101 and learnt everything about tires - i am a happy customer!|||16's is the WHEEL size. If all the TIRE sizes are the same (example 215-65 x 16) then use that size.|||christypooh87, I had similar problems with my Chevrolet Corvette and last month.
