The 1958 Buick 60 Century belongs to Buick’s flamboyant late-1950s period, when big proportions, bright trim, and a strong road presence defined the full-size American car market. Century models balanced Buick luxury cues with a more spirited personality, so tire choice affects both stance and overall character. This Buick uses a 760-15 bias-ply tire on a 15-inch rim, keeping it firmly in the sizing language of its era. Available choices include several wide whitewall treatments, a narrow whitewall option, and modern radial equivalents for owners considering a different driving presentation. The right decision usually comes down to restoration appearance, intended road use, and careful wheel and clearance verification.
Which Tire Size Is Right for The 1958 Buick 60 Century
The 1958 Buick 60 Century uses one primary tire size: 760-15. That is a bias-ply fitment on a 15-inch rim, and it is shared by the covered 8-cylinder sub-model. Since the size itself is straightforward, the real choice becomes whether to stay with a traditional bias-ply tire, which sidewall style best suits the car, and whether a radial equivalent deserves consideration for the way the Buick will be driven.
A 760-15 is a vintage numeric bias-ply size in which the 760 refers to an approximate 7.60-inch nominal section width and the 15 identifies the wheel diameter in inches. On the 1958 Buick 60 Century, this size preserves the period-style bias-ply construction and the visual character that goes with a full-size late-1950s Buick. Available choices include BFGoodrich, Coker Classic, Universal Vintage Tire, and Goodyear, with sidewall treatments ranging from narrow whitewall to several wide whitewall presentations. This size is the right starting point when the goal is maintaining the Buick’s original-era look while still comparing brand, series, and sidewall details carefully.
Sub-model fitment is straightforward for the covered 1958 Buick 60 Century configuration. The 8-cylinder version uses the same primary tire size, so the focus shifts from size differences to construction choice, sidewall appearance, and wheel confirmation.

Owners of a 1958 Buick 60 Century usually want clarity on 760-15 fitment, 15-inch rim compatibility, whitewall choices, and whether a radial equivalent makes sense. These FAQs focus on the exact size, construction, appearance, and road-use checks that matter most for this Buick.
Tire Size & Fitment
What tire size fits a 1958 Buick 60 Century?
The 1958 Buick 60 Century uses a 760-15 tire size. This is a vintage numeric bias-ply fitment mounted on a 15-inch rim, and it is the primary size for the covered 8-cylinder configuration.
That means the first step is not choosing between multiple primary sizes, but deciding how you want the car to look and drive within the 760-15 fitment. Whitewall width, tire series, and possible radial-equivalent alternatives become the main variables, especially if the Buick has been fitted with different wheels or suspension components over the years.
What size rim does a 1958 Buick 60 Century use?
The primary tire fitment for the 1958 Buick 60 Century uses a 15-inch rim diameter. That rim diameter matches the 760-15 tire size, where the final number identifies the wheel size in inches.
Rim diameter is only one part of the fitment picture, so it is still worth confirming the actual wheel on the car before buying tires. A Buick that has been modified, restored with replacement wheels, or converted to a radial alternative may need closer attention to wheel width, sidewall clearance, and overall tire proportions.
Does the 1958 Buick 60 Century 8 Cyl. use the same tire size?
Yes. The covered 1958 Buick 60 Century 8 Cyl. uses the same 760-15 bias-ply tire size. There is no separate primary tire size within this sub-model coverage that changes the basic fitment.
That consistency makes selection simpler because the key choice is not between different sub-model sizes. Instead, owners can focus on the style of whitewall, the tire series, and whether staying with bias-ply construction or considering a radial equivalent better suits the car’s restoration direction and expected road use.
Bias-Ply & Radial Options
Is 760-15 a bias-ply or radial tire for the 1958 Buick 60 Century?
For the 1958 Buick 60 Century, 760-15 is the primary bias-ply tire size. In this vintage numeric format, the size itself belongs to the traditional bias-ply sizing system used on many American cars of the period.
Keeping the Buick on a 760-15 bias-ply tire usually matters most to owners who want a traditional sidewall shape and period-style overall presentation. Anyone considering a radial alternative should treat that as a separate fitment decision and confirm wheel width, tire dimensions, and clearance rather than assuming every 15-inch radial option behaves the same.
What radial tire sizes are equivalent to 760-15?
Radial equivalents for 760-15 include 215R15 as an 80-series metric radial, P225/75R15 as a 75-series P-metric radial, P235/70R15 as a 70-series P-metric radial, and 760R15 as a bias-look radial equivalent. These are alternative sizing formats for owners evaluating a radial construction.
Each option approaches the original fitment a little differently in profile language and presentation, so the choice is not purely about matching the rim diameter. Wheel width, suspension condition, body clearance, and the Buick’s intended use all deserve a close look before changing from the original-style bias-ply construction.
What should I check before converting my 1958 Buick 60 Century from bias-ply to radial tires?
Start by confirming the actual wheel diameter and wheel width on the car, then compare the radial equivalent you are considering against the Buick’s available space at the fenders, suspension, and steering points. The recommended rim-width range tied to the radial equivalents is 6 to 8 inches.
A conversion decision should also account for how the car is set up today, not only how it left the factory decades ago. Replacement wheels, alignment settings, suspension wear, ride-height changes, and added load can all affect the result, so the safest path is to verify the full wheel-and-tire package before mounting a different construction.
Choosing the Right Tire
What should I consider when choosing a 760-15 tire for a 1958 Buick 60 Century?
Begin with the correct 760-15 size and decide whether the Buick’s mission calls for a traditional bias-ply tire or a separate radial-equivalent path. Within the bias-ply selection, the main differences are brand, tire series, and the visual effect of narrow versus wide whitewall styling.
A restoration-oriented car may lean toward the sidewall treatment that best matches the period look you want, while a regularly driven car may require closer attention to wheel compatibility and load specifications. It also helps to inspect the actual wheels on the car so the selected tire’s rim-width requirements align with the current setup.
What sidewall styles are available for 1958 Buick 60 Century tires?
The available 760-15 tires for a 1958 Buick 60 Century include both narrow whitewall and wide whitewall styles. Wide whitewalls dominate the selection, with several different whitewall widths available depending on the tire series and brand.
That gives owners room to tune the Buick’s appearance without changing the basic tire size. A broad whitewall generally reinforces the full-size late-1950s visual character, while a narrower whitewall creates a more restrained presentation, so the right choice depends on whether the car is being restored, preserved, or simply styled to personal taste.
What brands offer tires for the 1958 Buick 60 Century?
Tires in the 760-15 size for the 1958 Buick 60 Century are available from BFGoodrich, Coker Classic, Universal Vintage Tire, and Goodyear. Those offerings appear across series such as Silvertown Classic Bias Ply, Coker Classic Bias Ply, Universal Classic Bias Ply, and Super Cushion Deluxe.
Brand choice should be considered alongside the details that shape the finished result on the car. Sidewall treatment, series appearance, rim-width requirements, and the intended use of the Buick often matter more than the brand name alone, especially when trying to balance period-style presentation with practical road use.
Restoration & Appearance
Which tire should I choose for a period-style 1958 Buick 60 Century?
A period-style 1958 Buick 60 Century usually starts with the original-size 760-15 bias-ply format. That keeps the car in the sizing and construction family associated with late-1950s American full-size cars and preserves the traditional profile many restoration-minded owners want.
From there, the visual decision often comes down to whitewall treatment and brand or series preference rather than changing the size itself. If exact originality matters beyond general period style, it is wise to compare the tire choice against marque-specific restoration references and the car’s own historical details before settling on one presentation.
How does tire construction affect the appearance of a restored 1958 Buick 60 Century?
Tire construction changes more than the ride; it also affects how a restored 1958 Buick 60 Century looks at a glance. A bias-ply 760-15 maintains the traditional vintage sizing language and sidewall character, while a radial alternative can alter the visual impression even when the rim diameter remains the same.
That matters on a Buick from this era because the tire is a visible part of the car’s stance and overall proportion. Owners who want a more traditional presentation often stay with bias-ply or consider a bias-look radial, while others may accept a more modern look in exchange for a different construction approach.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1958 Buick 60 Century?
Yes. Modifications can change tire fitment on a 1958 Buick 60 Century even when the chosen tire is in the correct 760-15 family or a recognized radial equivalent. Different wheel widths, replacement rims, suspension changes, lowering, or brake upgrades can all alter the usable space around the tire.
That is why the actual car should be checked rather than relying only on year-make-model fitment. Steering travel, inner and outer fender clearance, and the wheel’s dimensions all deserve attention, especially on a large collector car that may have been restored or updated more than once during its life.
What should I inspect before driving a 1958 Buick 60 Century on new tires?
Before road use, inspect the wheels for proper condition, verify that each tire is seated correctly, and confirm air pressure, valve-stem condition, and basic clearance at full steering lock. It is also wise to look over suspension and steering components, since worn parts can affect how a large Buick tracks and responds.
A short initial drive should be used to recheck for rubbing, unusual vibration, or signs of uneven contact. Collector cars that spend long periods parked also deserve an extra look for fluid leaks, brake drag, or alignment issues that can shorten tire life even when the tire size itself is correct.
How should 760-15 tires on a collector 1958 Buick 60 Century be maintained?
760-15 tires on a collector 1958 Buick 60 Century should be inspected regularly for air loss, sidewall cracking, tread wear, cuts, bulges, and signs of age-related hardening. Proper inflation and periodic movement of the car are especially important on low-use vehicles that spend long stretches in storage.
Storage conditions matter almost as much as road mileage on an older collector car. Keeping the Buick away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires, while occasional checks of wheel condition and alignment can catch problems early before they affect ride quality or appearance.
