so my wife’s car has 205/60/16" tires on it and i want to know how much different the sizing is on a set of 205/65/15
I’m sure they’ll work, but is there a basic on-line calculator where i can plug this in and get the total diameter…
Tire rack says just take the aspect ration and mulitply by two then add the wheel diameter… i dont buy that.
heyy bing maybe this will help?

For those sizes, it says:
If your speed reads 65 miles/hr, you will in fact be going 64.5 miles/hr.
So yeah, not much of a difference at all.
^^your overall diameter will also be affected if the 16’s and 15’s are not the same width from the stretch but pretty minimal since i guess they’d be like 0.5 or an inch off if they were different.
convert width of the tire to inches, take the sidewall percentage of that, muliply by 2, add wheel diameter
Ex. 205mm = 8.071"
8.071 x 0.60 = 4.84
4.84 x 2 = 9.68
9.68 + 16 = 25.68" overall diameter
FYI, that calculator is awesome… exactly what i needed and i’ve used it a dozen times since… good link.
You can easily do it yourself like sidewayz did.
running the numbers through that calculator is faster… especially when you’re contemplating multiple tires sizes
Yeah, it’s great for that eh. I’m glad you found it usefull Bing.
this is what i use>>
anyone have a link to one of those charts that shows what tire sizes you should put on rim widths nad vice versa?

^^^it wont let me strech tires what the funk
this is the one right here
how about one of those charts that tell you what min / max tire size by wheel width??
Bing try this
