Curated tire comparisons
Explore four carefully selected tire size comparisons with calculated dimensions, practical trade-offs and interactive diagrams.
CURATED TIRE COMPARISON
175/65 R15 vs 195/65 R15
The aspect ratio stays at 65, but the sidewall grows because it is a percentage of width. The 26 mm diameter increase is substantial enough to deserve careful checks against the vehicle manufacturer’s specified sizes.

The extra 10 mm of nominal width also adds 5.5 mm to each sidewall. Both use a 16-inch wheel, but that alone does not establish that the same wheel width or vehicle can accept both.

225/45 R17 vs 235/45 R17
Keeping the 45 aspect ratio while adding 10 mm of width raises the diameter by 9 mm. Check the chosen tire model’s permitted rim widths and clearances before treating this as an alternative.

195/65 R15 vs 205/55 R16
A larger wheel does not necessarily mean a taller tire. The lower-profile 16-inch combination is 2.6 mm smaller overall and has 14 mm less sidewall, changing the potential impact-cushioning trade-off.
