Comparison
165/70 R14 vs 175/70 R14
Stepping from 165/70 R14 to 175/70 R14 keeps the 14-inch wheel but widens the section by 10 mm. This tire combination moves rolling diameter a touch off the original spec. The wider section adds contact patch and lateral stability, while eating into fender and suspension clearance.
Expect a slight but noticeable shift in indicated speed compared to the original tires. Diameter change stays inside the conservative ±3% safety window — an OEM-safe fitment on most vehicles.
TakeUseful when extra dry grip and stance matter more than a small fuel-economy hit.
Quick math: 175/70 R14 is 14.0 mm taller than 165/70 R14, shifting the speedometer by +2.39%.
