The single most reliable way to choose a tire size is also the simplest: check the sticker inside your driver’s door jamb, or your owner’s manual. That sticker lists the size your manufacturer engineered the car around — for speedometer accuracy, suspension geometry, and braking distances all calibrated to it.

Why “close enough” isn’t good enough

Tire size affects more than fitment. A significantly different overall diameter changes your speedometer’s accuracy, can affect ABS/traction-control calibration on newer cars, and changes ground clearance. A size that’s off by a lot can also rub against the wheel well or suspension components.

When an alternate size is genuinely fine

Manufacturers sometimes list two acceptable sizes for the same trim (commonly across staggered setups, or a base vs. a sport trim of the same model). If your door sticker itself lists more than one size, either is safe. Outside of that, don’t assume a “close” size is interchangeable without checking — an actual manufacturer-listed alternate is different from a tire shop’s approximation.

What we can and can’t confirm

We can search Go Mina’s catalog for your exact door-sticker size across all our stocked brands. What we won’t do is guess a size for you based on your car’s model name alone, because trim levels and years genuinely do vary. If you send us your door sticker or current tire’s sidewall text on WhatsApp, we’ll confirm before you order — this is a standard part of how we handle every size inquiry.

Practical examples, not guarantees

To illustrate the kind of sizes commonly seen on Egyptian roads: many compact sedans run something in the 185-205mm width range with a 15-16 inch rim; many mid-size SUVs run 215-235mm with 17-18 inch rims. These are examples of typical ranges, not a lookup table — always confirm against your own vehicle’s door sticker rather than a general pattern.

Balancing budget, brand, and application

Within your correct size, you’ll usually have a genuine choice across value, mid-range, and premium options — RoadX and Dynamo sit at accessible price points, Nexen and Nankang are Go Mina’s strongest-selling mid-tier lines, and Continental represents the premium end. All are available in the same verified size once you’ve confirmed it.

Every tire sold in Egypt has its full specification printed directly on the sidewall, in a format that looks like a code but is actually just a compact list of facts. Take a common size like 205/55R16 91V — once you know how to read it, you can check any tire in five seconds instead of guessing.

Width — the first number

The 205 is the tire’s width in millimeters, measured from sidewall to sidewall. A wider tire generally means more contact with the road, which can help with grip but also tends to increase price and sometimes fuel use slightly.

Aspect ratio — the number after the slash

The 55 is the aspect ratio: the tire’s sidewall height as a percentage of its width. Here, the sidewall is 55% of 205mm tall. A lower number (like 40 or 45) means a shorter, stiffer sidewall — common on performance and larger-wheel setups. A higher number (60, 65, 70) means a taller sidewall, which usually rides more comfortably and better absorbs Cairo’s rougher road patches.

Construction — the letter before the rim size

The R stands for radial construction, which is what almost every passenger tire sold today uses (the internal belts run radially across the tire). You will occasionally see other letters on older or specialty tires, but radial is the standard to expect.

Rim diameter — the number after R

The 16 is the wheel diameter in inches that the tire is built to fit. This number has to match your rim exactly — there is no “close enough” here.

Load index — the number after the rim size

The 91 is a load index, a code (not a direct weight) that maps to a maximum load the tire can safely carry per tire at full inflation. A higher number supports more weight. This matters more than most drivers realize for vehicles that regularly carry heavy loads — vans, pickups, and larger SUVs in particular.

Speed rating — the final letter

The V is the speed rating, a letter code for the maximum speed the tire is rated to sustain under its rated load. It is a safety ceiling, not a target — fitting a tire with a rating below your vehicle manufacturer’s recommendation is not advisable.

Where to find your car’s correct size

Your vehicle’s original size (and often an alternate size) is printed on a sticker inside the driver’s door jamb, and also listed in the owner’s manual. That sticker, not the tire currently mounted (which may have been swapped at some point), is the reliable source.

Finding the right tire at Go Mina

Go Mina’s tire catalog is searchable directly by size — enter the width, aspect ratio, and rim diameter and the filters narrow to what’s actually in stock, across brands like Sailun and Nankang. If you’re not sure which size fits your car, send a photo of your door jamb sticker on WhatsApp and we’ll confirm before you buy.
