Why Can’t You Just Replace The Tyres Of An Older Car?

It is feasible to remove some of the annoyances associated with driving a classic vehicle. You can upgrade the infotainment system or even replace the engine with an electric version. Safety devices, wheels, and engine design have all improved in recent years, but car technology has progressed in other areas as well. The tyres on the vehicle have also changed throughout the years. However, fitting modern tyres Wokingham to a vintage car isn’t as straightforward as putting on new rubber.

Tyres Of The Present Versus Older Ones

Bias-ply tyres are common on classic autos. There are multiple cords within the rubber that are diagonally interlocked. According to manufacturers, these strata are known as plies, thus the name. The pressure is transmitted and the vehicle turns because the plies are connected to the beads.

Radial tyres are now used on automobiles. Bias-ply cables run diagonally across beads in the bias tyre, but they travel at 90° in a radial tyre. Furthermore, these ropes are composed of steel rather than nylon. Expanded metal belts are also installed between the sheets and the external part of radial tyre. This design tweak brings a number of advantages.

Bias-ply tyres, for example, do not flex as effectively as modern tyres. The sidewalls are quite stiff because of the overlapped cables. This degrades the quality of the ride.

Since the surface and sidewall are linked, the tread will not bend if the sidewall does not. As a result, the tyre is unable to adjust to the terrain as effectively, resulting in poor handling. Furthermore, the nylon cables do not disperse heat properly, making it easier to lose grip.

Modern radial tyre, on the other hand, have steel belts that divider walls and tread movement. As a result, you receive a smooth ride without sacrificing traction. Furthermore, the belts widen the contact area, increasing handling even further.

In addition, new compounds improve the grip of the tyre itself. Designers can also install rain siping to channel excess water for improved wet-weather performance because of the increased surface area.

Although the greater grip is advantageous, it might pose a difficulty for antique cars.

New Rubber Means New Issues

Bias-ply tyres did not transfer pressure to its rims as evenly as current tyre do. As a result, putting a radial tyre on an old rim could cause the wheel to shatter or break completely. The most straightforward method is to match the old car’s chassis and rims. The automobile will then have considerable modern smoothness and performance, even if it isn’t precisely “original.”

Some tyre manufacturers, on the other hand, provide further assistance.

One of the most thrilling aspect of a classical car restoration job is getting your vehicle back on the street with new tyres. You can’t buy any tyres, though. In fact, choosing newer tyres can harm the old vehicle you’ve worked extremely hard to restore. These are all the explanations why you shouldn’t place new tyres on an old car, as well as the risks involved.


A tyre and bolt design is used to construct each type of vehicle. These configurations set the optimum dimensions of a model’s rims and, as a result, the types of tyres that may be mounted on them. As a result, only tyre that meet these requirements will correctly conform to a wheel. Old cars are noted for having a one-of-a-kind, if not eccentric, wheel designs. As a result, many modern tyres will be incompatible.


If you attempt to replace the tyres on an old car, the performance may suffer. It’s simpler for the tyres to slide and produce friction when driving because they don’t match well with the car’s wheel kind. It is not only an inconvenient method to operate, but it may also be quite hazardous if you lose power.

Wear & Tear

Another cause you can’t install current tyres on a vintage automobile is the lot of pressure they’ll be subjected to. To accommodate their increased performance, most classic cars, particularly supercars, sit uniquely on their suspensions. Certain tyres were not created with those varied pressure areas in mind. As a result, if you drive with them on the vehicle, you may notice more wear and tear and have to change them more frequently.


Overall, utilising newer tyres on classic vehicles deviates from the vehicle’s authenticity. You would like to see these automobiles returned to their factory condition when you attend classic car events. As a result, fitting modern-looking tyres to a luxury vehicle is both inappropriate and insulting of the craftsmanship. After all, when you’re willing to invest in the time and effort to restore an old vehicle, you should just do it right. If you have all of the necessary parts, repairing a classic vehicle is a fantastic experience. So contact the experts to make sure they have the exact tyres you require for the vehicle.
