Buying tyres online allows you to compare a vast catalog, but an almost identical model may be incompatible with your vehicle. Before finalizing your order, avoid these common mistakes.
1. Read only the width and diameter
Two tyres in size 205 R16 are not necessarily equivalent. You must check the complete dimensions: width, aspect ratio, construction, diameter, load index, and speed rating.
2. Blindly copy the currently mounted tyre
The current assembly may have been modified by a previous owner. Always verify against the manufacturer's approved dimensions and vehicle information.
3. Neglecting load and velocity indices
A correct size with an insufficient index is still a poor choice. The vehicle's weight, axle distribution, and expected performance must be taken into account.
4. Confusing M+S and 3PMSF
M+S is a marking linked to mud and snow performance. The 3PMSF symbol corresponds to snow performance validated by a standardized test. For French mountain areas subject to winter maintenance requirements, this difference is crucial.
5. Compare only the price
The price should be compared between truly equivalent tyres. Consider the season, the speed ratings, the European tyre label, the noise level, the homologations, and the intended use. A cheaper but unsuitable tyre will cost more if it has to be returned or replaced prematurely.
6. Mixing incompatible technologies
Run-flat, standard tyre, reinforced XL, manufacturer approval, or rotation direction are not merely aesthetic options. Check compatibility with other tyres, rims, the tyre pressure monitoring system, and vehicle specifications.
7. Forgetting the delivery and return conditions
Before ordering, please verify the address, phone number, delivery times, and return policy. Tyres are bulky, and an incorrect part number may result in shipping charges. See our page for details. Delivery and lead times and our return policy.
8. Mounting the tyres without a final inspection
Upon receipt, check the reference, dimensions, ratings, markings, absence of damage, and the number of tyres. Mounting must respect the correct direction of rotation, inner/outer face, pressure, balance, and tightening torque.
The pre-payment checklist
- Complete dimensions identical to an approved tyre size.
- Compatible load and speed ratings.
- Season and markings adapted to the route.
- Correct quantity: one, two or four tyres.
- Technology and certification verified.
- Exact delivery address and contact details.
If in doubt, don't order randomly. Send us the complete dimensions, model, year, and engine type via the Contact page.
