just wondering...

[craz235]

i have 98 cavalier 2.2l sedan

it have size 14 tire with like hub cap or whatever they are called.

i m wondering if i can buy tires to fit my 15 rim ( i have size 15 rims from my old 92 cavalier)

would the 15 work on my 98 chev cavailer? best tire size to fit 15?

would the result as driving or things like that be the same?

what pros and cons between the OEM tire size with hub cap and 15 rims?

not a big deal?

well mine is a 2000 2.2 and the oem size is 15

the original tire size for mine is 195 60 15

u can use the 15 maybe u have to adjust the speedo but i dont think is a big diference

besides 15 always handle better than a 14

just make sure the bolt pattern matches if it does u r good to go

[craz235]

that is why i alway hears that 15's handles better than 14's.

what you mean by changing the speedo and be sure that the rims have the same bolt pattern.

i believe that my oem size is 195/70-14

what is the recommend size if i wanna use the 15's?

You need to make sure the tire's overall diameter is as close to factory as possible for your speedometer and odometer to be accurate.

To calculate wheel diameter, use this formula:
tire Width * tire profile * 2 + wheel diameter

Example: With a 195/70-14 tire, the width is 195 mm (7.68 inches), the profile is 70% (.70) of the width, and the wheel size is 14 inches. So the overall diameter would be 7.68 inches * .70 + 14 inches = 24.75 inches.

To keep the same width tire but with a 15 inch rim, you'd have to decrease the profile size. So rearranging the equation, you'd get profile = (diameter - wheel diameter) / (width * 2), or (24.75 inches - 15 inches) / (7.68 inches * 2) = .63. Since they don't make a 63 series tire, you'd have to settle for either a 60 series (spedometer would read fast) or a 65 series (speedometer would read slow). So a 195/65-15 tire would be the best bet if you wanted to keep the same tire width. You can play with the width a little though. Bumping the tire up to a 205/60-15 would give you slightly more contact area (traction) as well as better handling at the cost of ride quality...while giving you only a .25% difference in diameter. This is what I have on my car right now actually.

Here is a nice webpage that does all the calculations for you. You can specify what range of widths, profiles, and/or wheel sizes as well as the percentage variance from the factory diameter to get you a "best fit". It will also tell you the milage and speed differences.

i am tryin to understand the link you had for me about tire sizes.

i m thinkin 195/65-15
205/60-15

either one above would be fine? i want tire to have more room u know especially rubbing in turns.

205/60-15 would be the better match. More width, lower profile, and the overall diameter is closer. The ride difference between a 205/60 and 195/65 profile would be minimal anyways.

Is it possible to adjust the speedometer to show a higher or slower speed than you are actually going?
