2000 SE tire size question

[Guest MontanaPathy]

I have read through the posts regarding tire size, my question is this...I'm in the market for new tires, currently I have 245/70/R16, i'd like to go to a little bit taller tire w/out any special modifications...would 245/75/R16 fit, I'm assuming that it's the second number, the 75, that indicates tire height, I'm used to thinking of tires as 31/10.50,33/9.5...this metric is confusing me...What is the tallest tire i can fit w/out a lift? the current size seem to be a bit small for the car. I'm not looking to go wider, I like how they are just inside the fenders, but a bit taller wouldn't hurt...I've seen that standard size is 255/65/R16, so i assume mine are already larger than stock...so what would going to 245/75/R16s do for me?

 

thanks

245/70/R16 gives you a 29.5" tire diameter. Going to 245/75/16 will increase the diameter an inch to 30.5.

metric isn't that bad. Here's how it works:

 

the 1st number is the tread width in mm. Ex. 245 / 25.4 = 9.65" So these tires would be 9.65 inches wide

(there are 25.4 mm in one inch)

 

Next, you find the sidewall height. Ex. If you had 245/75, that means that each sidewall height is 75% of the width. So 245 x .75 = 183.75 mm. Multiply that by 2 (because there is a sidewall on either side of the rim) and you get 367.5 mm

 

So, if your rim is 16 inches tall, 16" = 406.4 mm (16x25.4)

 

Then, 367.5 mm (total sidewall height) + 406.4 mm (rim height in mm) = 773.9 mm in total tire height. To get this in inches, just convert it. 773.9 / 25.4 = 30.46"

 

So, Like DJ said, the 245/75/16's would be about 30.5x9.5 R16. Anything that is less than 31" in overall tire height should fit with minimal to no rubbing
