1958 Alvis Tire Fitment Guide

1958 Alvis vehicles covered here use two tire sizes, and both apply to the Alvis TC: 175R15 and 600-15. Both sizes mount on 15-inch rims. For 600-15, listed products show rim width ranges of 4.00 to 4.50 inches for the wide-whitewall version and 4.50 to 5.00 inches for the blackwall version.

That means the first step is not choosing between different Alvis models, but deciding which construction type you want on your TC. The radial 175R15 and the bias-ply 600-15 serve different ownership goals, so it is wise to confirm your actual wheel width and the look you want before settling on one size.

On a 1958 Alvis, 600-15 is a traditional numeric bias-ply size. The "600" refers to the nominal section width in the older inch-based system, and the "15" is the wheel diameter in inches. It is an era-correct style of size marking for a late-1950s British car such as the Alvis TC.

Choosing 600-15 generally points you toward a more original visual character and the driving feel associated with bias-ply construction. It is also the size with clearly listed Blackwall and Wide Whitewall choices, so owners who care about presentation at shows or on a restoration often start there.

On a 1958 Alvis, 175R15 is a Euro-metric radial size. The "175" is the section width in millimeters, the "R" identifies radial construction, and the "15" is the rim diameter in inches. Because no aspect ratio is written in the size, it follows the older Euro-metric convention used on many classic radial fitments.

That size appeals to owners who want a radial option while keeping the correct 15-inch wheel diameter. It is still important to confirm overall fit on the actual car and wheel, but the bigger decision is usually whether you want radial road behavior or the more traditional feel of a bias-ply setup.

For the 1958 Alvis coverage here, there is one model core: the Alvis TC. That model is associated with two tire sizes rather than one, namely 175R15 and 600-15. So there is no model-to-model split within the year; the variation is between construction types and size formats on the same model.

That simplifies shopping compared with a larger lineup, but it does not remove the need to choose carefully. A TC owner should still verify which size best suits the car's current wheels, the intended driving style, and whether the goal is a more authentic period presentation or a radial-equipped road car.

For a 1958 Alvis TC, the choice between 175R15 and 600-15 is mainly a choice between radial and bias-ply construction, since both fit 15-inch rims. The 600-15 aligns with the traditional tire type of the era, while 175R15 represents a radial alternative that keeps the same wheel diameter but changes the construction and sizing convention.

Owners aiming for a more period-correct restoration usually gravitate toward the bias-ply 600-15, especially when sidewall appearance matters. Owners who plan to spend more time on regular roads often prefer the radial path. Before deciding, check the wheel width on your TC and make sure the specific tire's sidewall style and construction match your expectations.

For 1958 Alvis applications in 600-15, sidewall styles include both Blackwall and Wide Whitewall. The listed BFGoodrich choices are the same basic bias-ply series with different visual presentation. That gives Alvis TC owners some flexibility in appearance while staying within the same general size and construction family.

A blackwall usually suits a restrained European luxury-sporting look more naturally, while a wide whitewall creates a brighter period custom or show-oriented presentation. The right choice depends less on mechanical fitment than on how authentic you want the finished car to look for its market, coachwork style, and restoration theme.

BFGoodrich is the listed brand with available products for 1958 Alvis fitments, specifically in 600-15 bias-ply form. Within that size, BFGoodrich offers both Blackwall and Wide Whitewall versions from the Silvertown Classic Bias Ply line. The radial 175R15 size is part of the fitment range for the Alvis TC as well, but brand choice should be confirmed at the individual product level.

Brand matters on a collector car because it often affects sidewall appearance, casing style, and how closely the tire matches the era of the vehicle. For many buyers, the more useful first decision is still size and construction. Once that is settled, comparing available brands and sidewall treatments becomes much more straightforward.

For 1958 Alvis applications in 600-15, listed rim width ranges depend on the specific tire version. The BFGoodrich 600-15 wide-whitewall is shown for 4.00 to 4.50 inch rims, while the BFGoodrich 600-15 blackwall is shown for 4.50 to 5.00 inch rims. Both are 15-inch rim applications.

That overlap means wheel width should be checked before choosing between sidewall styles, not just before choosing a size. If your TC is wearing original wheels, measure the actual rim width rather than assuming it. Matching the tire to the wheel correctly helps preserve the intended profile and reduces fitment surprises after mounting.

Tube requirements for 1958 Alvis tires should be confirmed on the exact product you plan to fit. The listed 600-15 bias-ply products do not carry TT or TL markers in the size description shown here, and 175R15 should likewise be checked by specific tire specification before installation. On a car of this age, wheel condition also matters alongside the tire itself.

That makes tube use as much a wheel-and-product question as a size question. If your Alvis still has original-style wheels, inspect the inside of the rim, the valve hole, and the bead seat condition carefully. A marque specialist or experienced vintage tire installer can help you match the correct setup to the wheel you actually have.

Both listed 1958 Alvis TC tire sizes use a 15-inch rim diameter, so original 15-inch wheels can often serve as the starting point for either 175R15 or 600-15. The key point is that common rim diameter does not automatically mean every wheel width is equally suitable for every tire version.

That is especially important because the available 600-15 products already show different approved rim-width ranges depending on sidewall version. Before fitting either size to original wheels, confirm the wheel's actual width and condition. That check matters more than assuming interchangeability simply because both sizes share the same 15-inch diameter.

A 1958 Alvis should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment. Keep the tires clean and properly inflated, and if the car sits for extended periods, move it occasionally or support it in a way that reduces prolonged loading on one contact patch. Bias-ply tires are especially prone to temporary flat-spotting during long storage.

Those simple precautions help preserve both sidewall appearance and casing integrity on a collector car that may not be driven often. If your TC is fitted with bias-ply tires, expect the first few miles after storage to feel different until the tires warm and settle. Radials generally tolerate static storage better, but they still age from heat, sunlight, and ozone.

On a 1958 Alvis, tire age usually matters more than mileage. A collector-car tire should be evaluated regularly once it reaches the five- to seven-year range, and replacement becomes a serious consideration as it approaches around ten years, even if tread depth still looks good. The DOT date code on the tire sidewall is the best guide to actual age.

That matters because many Alvis cars cover limited annual mileage and can appear fine while the rubber quietly hardens or cracks with time. If your TC is driven only occasionally, do not judge tire life by tread wear alone. Sidewall condition, ride changes, pressure retention, and age should all weigh into the replacement decision.

Tires on a 1958 Alvis should be inspected before every drive and again before any longer outing. Check for sidewall cracking, cuts, bulges, uneven wear, and loss of air pressure, and look closely at valve stems and the spare as well. On an older collector car, a quick visual check is one of the most valuable pre-drive habits you can have.

A more thorough inspection every few months is also wise, especially if the car is stored for stretches between uses. Pay attention to how the TC feels on the road too. Changes in steering response, vibration, or pull can point to tire aging, pressure drift, or wheel issues before a problem becomes obvious in the garage.

For a 1958 Alvis TC, bias-ply construction is the historically correct starting point for an original-era fitment, and 600-15 matches that period type. Radials were emerging in the market by the late 1950s, but a bias-ply tire remains the safer assumption for authenticity unless a specific market, coachbuilder, or period record shows otherwise.

If you are restoring a TC for judged presentation, begin with the correct size family, the right construction type, and an appropriate sidewall style before worrying about finer details. For market-specific confirmation, especially on coachbuilt or export cars, marque clubs and Alvis specialists are the best next step because presentation standards can vary.

Correct tire fitment matters a great deal when showing a 1958 Alvis because judges and knowledgeable enthusiasts often notice size, construction, and sidewall style immediately. A tire that looks too modern, uses the wrong construction for the restoration goal, or carries an obviously mismatched sidewall treatment can distract from an otherwise well-finished car.

For many TC restorations, that means a bias-ply tire in the proper size family will look more convincing than a modern-looking substitute, even if the car is not being judged at the highest level. Event standards vary, so owners chasing concours accuracy should confirm class expectations with the organizing club or marque community before finalizing tire choice.

For the 1958 Alvis TC, both BFGoodrich 600-15 options share the same bias-ply construction and the same listed maximum load of 1150 pounds at 32 psi, but they differ in appearance, weight, and approved rim-width range. The wide-whitewall version weighs 19 pounds and is listed for 4.00 to 4.50 inch rims, while the blackwall weighs 18 pounds and is listed for 4.50 to 5.00 inch rims.

That means the decision is not only visual. A TC owner should choose the sidewall treatment that suits the restoration theme, then verify that the wheel width lines up with the specific version. If your car sits near the overlap point, measuring the actual rim before choosing between whitewall and blackwall is worthwhile.

1958 Alvis tires can be suitable for highway driving when they are the correct size, in good condition, properly inflated, and matched to the way the car is used. The 1958 Alvis TC is listed with both a radial 175R15 option and a bias-ply 600-15 option, and each construction brings a different road feel. Actual highway capability should be confirmed on the individual tire, including any speed symbol shown on that product.

On a car of this era, tire condition is only one part of the equation. Brake performance, suspension condition, steering play, wheel balance, and alignment all shape how comfortable a TC feels at sustained speed. Even if the tire itself is rated for more, the overall mechanical condition of the Alvis should set the pace for longer highway use.

For 1958 Alvis applications in 600-15, the listed products carry a maximum load rating of 1150 pounds at 32 psi. That figure is a tire rating, not automatically the pressure you should run on the car in service. Inflation for the Alvis TC should be set with reference to the car's original factory guidance and the tire manufacturer's recommendations for the exact product fitted.

Avoid transferring a pressure figure from one size or construction type to another without checking. Bias-ply and radial tires can respond differently in service, and the right operating pressure depends on the tire, wheel, and vehicle. Starting with the car's handbook and then verifying the tire maker's recommendation is the soundest approach.

Before taking a 1958 Alvis on a longer drive, inspect each tire for cracking, cuts, bulges, embedded objects, irregular wear, and correct inflation. Check the valve stems, confirm the spare is usable, and make sure the tires have not aged out. A car that looks fine parked can reveal problems only after heat builds on the road.

A longer-trip inspection should also include the broader basics expected of a late-1950s touring car: wheel fastener security, steering response, brakes, and fluid levels. If the TC has been sitting, a short local test drive before committing to distance is wise. That gives the tires and the rest of the chassis a chance to reveal any issues early.
