1958 Alvis TC Tires

The 1958 Alvis TC is associated with two primary tire sizes: 600-15 in bias-ply construction and 175R15 in radial construction. Both sizes use a 15-inch rim, so the fitment question is not about wheel diameter alone, but about which tire construction and size convention matches the car’s current setup.

A car that still wears period-style wheels and tires may be best evaluated around the 600-15 bias-ply size, while a car already set up for radials may point toward 175R15. Checking the existing tire markings, wheel width, and clearance around the fenders and suspension helps confirm which of the two primary sizes belongs on the car.

The 1958 Alvis TC uses a 15-inch rim diameter with both of its associated tire sizes. That applies to the 600-15 bias-ply fitment and the 175R15 radial fitment, so either primary size is built around the same basic wheel diameter rather than two different rim diameters.

Rim diameter is only one part of the fitment picture. Wheel width still matters, especially when comparing a traditional 600-15 bias-ply with radial alternatives or with a 175R15 setup. Measuring the wheel and checking the tire currently mounted on the car is the most useful step before selecting a replacement.

The 1958 Alvis TC 108G is associated with both 600-15 bias-ply and 175R15 radial tire sizes. In practical terms, that means the covered sub-model does not force a single construction path, and the car may be encountered with either a traditional numeric bias-ply size or a Euro-metric radial size.

That makes the existing wheel-and-tire setup especially important to verify before ordering. Looking at the tire sidewall, confirming the 15-inch rim, and checking wheel width will usually answer the question faster than relying on appearance alone. It also helps prevent choosing a radial or bias-ply size that does not match the car’s present configuration.

On the 1958 Alvis TC, 600-15 is a bias-ply tire size. It uses the older numeric bias-ply sizing format, where the 6.00 designation refers to the nominal section-width class and the 15 indicates rim diameter. The separate 175R15 fitment is the radial-format option associated with this model.

That distinction matters because bias-ply and radial tires can change both appearance and vehicle behavior. A 600-15 choice keeps the traditional size format, while a move toward radial construction should be checked against wheel width, overall tire dimensions, and body or steering clearance. Mixed wheel setups or long-ago modifications are worth confirming before making the switch.

Radial equivalents for 600-15 include 165R15, P165/75R15, and P175/70R15. Those correspond to an 80-series metric radial, a P-metric 75-series radial, and a P-metric 70-series radial. A recommended rim-width range of 4 to 5 inches is associated with these equivalent options.

These sizes are useful comparison points, not automatic replacements. Each one uses a different sizing convention and profile family, so the right choice depends on the wheel width already on the car and on available clearance. Checking section width, stance, and steering room before conversion helps avoid selecting an equivalent that changes the fitment unexpectedly.

Start by confirming the existing wheel diameter and wheel width, then compare the radial size being considered against the current 600-15 setup. For a 1958 Alvis TC, the radial-equivalent choices tied to 600-15 are 165R15, P165/75R15, and P175/70R15, and the associated rim-width range is 4 to 5 inches.

Construction changes should also be evaluated in the context of the whole car. Check fender and steering clearance, suspension condition, and whether the Alvis has aftermarket wheels or prior modifications. A collector car that has sat for long periods deserves an extra look at wheel condition and alignment before regular road use on a different tire construction.

Choosing a 600-15 tire for a 1958 Alvis TC starts with confirming that the car is actually using the bias-ply fitment rather than the 175R15 radial size. Within 600-15, the available BFGoodrich Silvertown Classic Bias Ply options differ by sidewall presentation and rim-width specification while retaining the same traditional size and construction format.

Appearance is usually the next decision. A blackwall tire gives a restrained look, while the 2.625-inch wide whitewall creates a stronger late-1950s visual statement. It also helps to compare wheel width, maximum load rating at the stated pressure, and how the tire choice fits the car’s intended use, whether that is display, light touring, or restoration-focused driving.

For the available 600-15 products used on the 1958 Alvis TC, the sidewall styles include blackwall and wide whitewall. Both are offered within BFGoodrich Silvertown Classic Bias Ply selections, so the sidewall decision is mainly about presentation rather than changing the underlying size category.

Sidewall style can alter the car’s visual character more than many buyers expect. A blackwall usually keeps the look more understated, while a wide whitewall leans further into a dressed, period-style appearance. It is smart to choose the sidewall treatment only after confirming the correct tire size and construction for the car’s existing wheel setup.

The available product assortment for the 1958 Alvis TC includes BFGoodrich in the 600-15 size. Those products fall within the Silvertown Classic Bias Ply series and cover both blackwall and wide whitewall sidewall treatments, giving a traditional bias-ply choice for the Alvis owner who is working within that primary size.

Brand is only one part of the decision. The more important first step is confirming whether the car is on the 600-15 bias-ply fitment or the 175R15 radial fitment, since the two represent different construction paths. After that, compare the tire’s sidewall style, wheel-width suitability, and the look you want the finished car to present.

For a period-style 1958 Alvis TC, the 600-15 bias-ply size is the natural starting point because it preserves the traditional numeric sizing format associated with the car’s era. Available choices in that size include BFGoodrich Silvertown Classic Bias Ply tires, giving a restoration-oriented path without assuming one exact tire treatment suits every car.

The final decision depends on how closely the car is being preserved and how it will be used. Buyers concerned with exact originality should compare tire appearance against marque references, old photographs, and other vehicle-specific history. For many owners, the goal is a convincing late-1950s presentation that also respects the car’s current wheel setup.

Tire construction changes the look of a restored 1958 Alvis TC as much as the size itself. A 600-15 bias-ply tire keeps the car in a more traditional visual language, while a 175R15 radial introduces a later-style sizing format and a different overall presentation even though both use a 15-inch rim.

That matters on a car where wheel opening shape, sidewall height, and stance all contribute to the finished appearance. Buyers restoring for shows, marque events, or a period-style road look often start by deciding whether traditional construction is part of the goal. Once that is settled, sidewall treatment becomes the next visible styling choice.

Yes, modifications can affect tire fitment on a 1958 Alvis TC even when the car still uses a 15-inch rim. Changes to wheel width, wheel offset, suspension height, steering components, or bodywork can alter how a 600-15 bias-ply or 175R15 radial sits in the wheel opening and clears the surrounding hardware.

A car that has been updated over the years should be measured rather than assumed to match a stock-style setup. Looking at the actual wheel dimensions, checking clearance at full steering lock, and noting any contact marks around the fenders or suspension can prevent costly mistakes. Those checks matter even more when changing construction or trying a radial equivalent.

Before driving a 1958 Alvis TC on new tires, inspect the wheels, valve stems, lug hardware, and the general condition of the suspension and steering components. It also helps to verify tire pressure, confirm that the mounted size matches the intended setup, and make sure there is no interference as the wheels are turned lock to lock.

Collector cars often spend long periods parked, so age-related issues elsewhere on the chassis can appear once the car returns to the road. A short, careful test drive followed by a second inspection for rubbing, air loss, or looseness is a sensible habit. That approach is especially useful after changing from an older worn tire to a fresh one.

600-15 tires on a collector 1958 Alvis TC should be maintained with regular pressure checks, visual inspections for sidewall cracking, cuts, bulges, and uneven tread wear, and periodic review of overall tire age and condition. Bias-ply tires on low-use cars can look acceptable at a glance while still needing closer inspection before regular road use.

Storage conditions matter as much as mileage on a seldom-driven Alvis. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tire casing over time. Occasional movement, proper inflation, and inspection before longer drives can reduce flat spotting and help catch problems before they become roadside issues.
