# What circumference differences come from different wheel sizes?

What circumference differences come from different wheel sizes?

I can not find the outer size of these two vehicles....

Honda Civic 2013 Sedan

Honda CR-V 2017 EX

Can you? I guess i get thrown by "wheel",  "tire", "rim", etc.

I need to see a ratio, such as that the CR-V has a circumference that's 55% larger than the Civic...

It'd be great is a car buff could help.

Thanks.

Perfect!

Revs/Mile is what I was seeking.

Tire Size(s) - 2013 Civic
195/65R15 = 25x7.7R15 -> Circumference "78.4" -> "808 Revs/Mile".

Tire Size(s) - 2017 CR-V
235/60R18 = 29.1x9.3R18 -> Circumference "91.4" -> "693 Revs/Mile"
235/55R19 = 29.2x9.3R19 -> Circumference "91.6" -> "692 Revs/Mile"

So, the Honda Civic requires 16.73% more turns of the axle, per mile, than the Honda CR-V.

The comparison Civic had 106K miles,  versus the comparison CR-V, which had 113K miles..

106K X 1.1673 == 123,733 miles

123,733 miles (normalized Civic miles)
- 113,000 miles (actual CR-V miles)
=======
10,733 miles (in favor of the CR-V)

THANKS!
