Tires are crucial to your vehicle’s overall performance, comfortability, and safety. Therefore, choosing the correct tire is essential. When changing the tires on your car, it’s common to wonder if you could use a slightly different size than what’s currently on your vehicle.
We can install tires that are slightly different in size from the ones fitted by the car manufacturer on all vehicles without needing to change the rim. Different size tires can change your vehicle’s performance, stability, comfort, and safety. However, you have to choose the correct size.
In this article, I’ll cover you can use 195 tires instead of 185 tires. Different between 195 vs 185 tires and answer the more frequently asked questions.
In This Article:
What are 195 tire specifications?
The 195 tire size refers to the maximum width from sidewall to sidewall in millimeters when the vehicle is fully loaded. This size tire is manufactured in different rim sizes and aspect ratio tires, and therefore 195 tires are available in different diameters, circumferences, sidewall heights, and radii.
What are 185 tire specifications?
The 185 tire size refers to the width in millimeters and is measured from sidewall to sidewall. That is the standard tire width measurement. The exact specifications of a 185-size tire can vary depending on the aspect ratio and rim size. Therefore we can find different circumferences, sidewall heights, and radius tires on the market.
Can I Use 195 Tires Instead Of 185 Tires?
Yes. You can use 195 tires instead of 185 without changing the rim. The 195 and 185 tires can easily be fitted on 6 or 6.5 inches-wider rims, but the optimum size is 6 inches. Your new tires should have the same or higher speed rating and load capacity index recommended by the vehicle manufacturer.
When interchanging different size tires, the overall diameter difference should be below 3% to maintain the height. You can manage this diameter difference below 3% by adjusting the aspect ratio.
Can I Use 185 Tires Instead Of 195 Tires?
Yes. You can use 185 tires instead of 195 without changing the rim. These are interchangeable tires, and compatible rim range from 6 and 6.5 inches, and 6 inches is the optimum size. When using a new tire set, new tires should have the same or higher speed rating and load capacity index recommended by the vehicle manufacturer.
When interchanging 185 tires instead of 195, you must choose the aspect ratio appropriately to maintain the overall diameter difference below 3%. This will help to preserve height the same as stock tire.
Different Between 195 Vs 185 Tires.
The main difference between 195 vs 185 is the tire width. These two tires’ width difference is 10 millimeters. The 195 is a wider tire compared to the 185. Generally tire’s width mention in millimeters. The 185 and 195 are the width in millimeters and are measured from sidewall to sidewall.
The 195 tire is wider than the 185 tire, which means it has a larger contact patch. This can improve the handling and provide excellent grip, especially in cornering and braking. Furthermore, wider tires enhance the vehicle’s appearance by giving a sportier and more aggressive look.
On the other hand, 185 narrow tires provide better fuel economy, less rolling resistance, and less noise. Furthermore, 185 narrow tires may be less expensive than their wider counterparts.
There are different aspect ratios and diameter tires available in the market. Depending on the aspect ratio and diameter, tires’ overall diameter, section width, circumference, sidewall height, and revs per mile change.

Comparison of 195 Vs 185 Tires.
| Parameter | 195 Tire | 185 Tire |
|---|---|---|
| Section Width | 195mm | 185mm |
| Contact Patch | Larger, which can improve grip and handling | Smaller, which can improve fuel efficiency |
| Handling | Potentially better, as a wider tire may provide better traction and stability | Potentially worse, as a narrower tire may have less grip and stability |
| Fuel Efficiency | Potentially worse, as a wider tire may have higher rolling resistance and require more energy to move | Potentially better, as a narrower tire can generate less rolling resistance and require less energy to move |
| Ride Comfort | Potentially harsher, as a wider tire can transmit more road imperfections and vibrations to the cabin | Potentially smoother, as a narrower tire can absorb more road irregularities and provide a more comfortable ride |
| Noise | Potentially louder, as a wider tire can generate more noise from tire tread and air turbulence | Potentially quieter, as a narrower tire can generate less noise and turbulence |
| Appearance | Sportier or more aggressive, as a wider tire can fill the wheel well and give the car a more muscular stance | Less bold, as a narrower tire can look less imposing and aggressive |
| Price | Potentially more expensive, as wider tires tend to cost more than narrower ones | Potentially less expensive, as narrower tires tend to be less expensive than wider ones |
Can I Use 185 tires front and 195 Rear?
Yes, you can use 185 front axel and 195 tires for the rear axle. This staggered wheel arrangement improves the vehicle’s overall handling, cornering, better grip, and shorter braking distance.

195/55r15 vs 185/60r15.
195/55R15 and 185/60R15 are both tire sizes that can fit a 15-inch diameter and 6 or 6.5 inches-wider rims. The first number in each dimension is the tire’s width in millimeters, and 195 is a wider tire than 185 tires. The second number is the aspect ratio of the tire, which is the height of the sidewall as a percentage of the width, and 55 is a shorter sidewall compared with 60.
The 195/55R15 tire will have a wider contact patch, providing better grip and handling. However, the shorter sidewall can make for a harsher ride and more susceptible to pothole damage. The 185/60R15 tire has a taller sidewall, providing better comfort and absorbing shocks but less grip and handling performance.
The 195/55R15 may be better if you prioritize performance and handling. The 185/60R15 may be better if you prioritize ride comfort.
