Fitting Tyres to Alloys – UK Essential Guide: 5 Steps

Know Your Original Tyre Size

To find your car’s OEM tyre size for fitting tyres to alloys:

    • Your car’s manual (in the glovebox, under “Specifications” or “Tyres”)
    • The driver’s side door jamb (look for a tyre placard sticker)
    • The sidewall of your current tyres. For example, you’ll see something like 205/55 R16.

What do those numbers mean?

    • The first number, 195, is the tyre’s width in millimeters.
    • The second, 55, is the aspect ratio (sidewall height as a percentage of width).
    • The “R” means radial construction, standard for modern tyres.
    • The last number, 16, is the alloy wheel diameter in inches.
    • The tyre’s load index and speed rating.

91 (Load Index): This number indicates the maximum weight the tyre can carry when properly inflated. A load index of 91 means the tyre can support 615 kg (1,356 lbs) per tyre. You can find load index charts online, like on TyreSafe.org, to check other values. V (Speed Rating): This letter shows the maximum speed the tyre is certified for. A “V” rating means the tyre is safe up to 149 mph (240 km/h). For comparison, a “T” is 118 mph, and a “W” is 168 mph. For upgrades, like moving to 17-inch alloys, you need a lower the aspect ratio (e.g., 215/45 R17) to keep the total diameter close to 24.9 inches.

Why Fitting the Correct Tyres to Alloys Matters. 

Fitting tyres to alloys correctly is crucial for your car’s performance and safety. Mismatched tyres and alloys can cause handling issues, uneven wear, or even damage your drivetrain. A proper fit ensures your vehicle stays within the manufacturer specs, maintaining speedometer accuracy and fuel efficiency. For example, upgrading to 18-inch alloys requires a lower-profile tyre to keep the overall diameter correct. Ignoring this can void warranties. Learn more about tyre safety at Michelin’s guide.

How to Choose the Right Tyre Size for your Alloys.

Choosing the right tyre size for your alloys is key to safe fitting. Check your car’s manual for the original size, like 205/55 R16, which matches a 16-inch alloy. When upgrading, say to 17-inch alloys, you need a tyre with a lower sidewall (e.g., 225/45 R17) to keep the total diameter close to 24.9 inches. Incorrect sizes will mess with handling and speedometers. Using calculators and manufacturer guides. Check UK tyre regulations for details.

Avoiding Common Mistakes in Fitting Tyres to Alloys.

Fitting tyres to alloys can go wrong fast without care. Common mistakes include ignoring load and speed ratings – a T-rated tyre (118 mph) won’t cut it for high-performance alloys. Mixing brands or using cheap tyres leads to uneven wear. Always balance and align after fitting tyres to alloys; skipping this ruins tyres fast. Avoid mistakes with RAC’s tyre tips.

Repairing typically involves fixing minor damage through techniques like sanding, filling, or repainting, while refurbishing often includes a full overhaul, such as stripping, powder coating, and polishing for a like-new finish.
