The 1980 Mazda Trucks B2000 came from the compact-pickup era when small Japanese trucks earned a reputation for simple utility, manageable size, and everyday drivability. Buyers today often keep these trucks on the road as honest workhorses, light restorations, or period-style survivors. Tire fitment on the 1980 Mazda Trucks B2000 spans three 14-inch sizes: 195R14 radial, 6.00-14 bias-ply, and ER70-14 radial, so the decision is less about wheel diameter and more about construction and presentation. Available choices include a traditional numeric bias-ply format and radial options with vintage-style sidewall treatments. That makes it important to match the tire to the truck's current wheels, intended road use, and restoration direction.
Which Tire Size Is Right for The 1980 Mazda Trucks B2000
The 1980 Mazda Trucks B2000 uses three primary tire sizes, all built around a 14-inch rim. Because the Base, Sundowner, and Sundowner Sport all share these sizes, the key step is confirming which tire construction and appearance suit the truck's current setup, rather than sorting fitment by sub-model.
195R14 is a euro-metric radial size in which 195 identifies the nominal section width in millimeters, R indicates radial construction, and 14 identifies the wheel diameter in inches. On the 1980 Mazda Trucks B2000, it represents a modern radial-style sizing convention within the truck's original 14-inch wheel format. This size suits buyers who want a radial tire presentation rather than an older numeric bias-ply look. It is worth checking the actual wheel width and the truck's current ride height or wheel setup before settling on this size for regular road use.
6.00-14 is a numeric bias-ply size, where 6.00 refers to the nominal section width in inches and 14 indicates the rim diameter. For the 1980 Mazda Trucks B2000, this size speaks to a more traditional light-truck tire format and a period-style bias-ply construction. It is the right place to start when maintaining an older driving feel or a restoration-oriented appearance built around vintage tire sizing. Before choosing it, confirm that the truck still uses wheels and overall clearances appropriate for a bias-ply tire rather than a later radial-oriented setup.
ER70-14 is an alphanumeric radial size, with the letter designation indicating the tire's size class, the 70 identifying its profile family, and the R confirming radial construction on a 14-inch rim. On the 1980 Mazda Trucks B2000, this size offers a radial choice with a distinctly vintage performance-era look. Available products in this size come from Firestone's Wide Oval Radial line in Redline and RWL sidewall styles, giving the buyer an appearance choice as well as a size choice. It is a useful option when the goal is radial construction with stronger period styling.
Fitment is straightforward across the covered 1980 Mazda Trucks B2000 sub-models because the same three 14-inch tire sizes appear throughout. That means checking the truck's actual wheels and preferred tire construction matters more than choosing between Base, Sundowner, and Sundowner Sport.

1980 Mazda Trucks B2000 Base
The 1980 Mazda Trucks B2000 Base shares the same 14-inch fitment range as the other covered sub-models, including radial and bias-ply choices. Tire selection here comes down to whether the truck is being kept in a more traditional format or updated with a radial option and vintage-style sidewall presentation.
The 1980 Mazda Trucks B2000 Sundowner uses the same tire-size range as the rest of the B2000 lineup covered here. That keeps the focus on choosing between 14-inch bias-ply and radial constructions and confirming that the wheel setup still matches the intended tire format.
The 1980 Mazda Trucks B2000 Sundowner Sport follows the same tire-fitment pattern as the Base and Sundowner. For this sub-model, the real choice is whether to stay with a traditional bias-ply style or use one of the radial options that preserve a more vintage look on a 14-inch wheel.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 1980 Mazda Trucks B2000 Tires for Sale
Current product choices center on ER70-14, with Firestone Wide Oval Radial options that use bias-look radial construction and offer either Redline or RWL sidewall styling. That gives the B2000 buyer a focused comparison between two vintage-inspired radial presentations in the same 14-inch size.
These FAQs focus on the 1980 Mazda Trucks B2000's three tire sizes, 14-inch wheel fitment, bias-ply versus radial choices, vintage-style sidewall options, and the practical checks worth making before road use or a restoration-minded tire change.
Tire Size & Fitment
What tire size fits a 1980 Mazda Trucks B2000?
The 1980 Mazda Trucks B2000 uses three primary tire sizes: 195R14, 6.00-14, and ER70-14. Those sizes cover both radial and bias-ply constructions, and all of them are built around a 14-inch rim diameter.
The practical choice is deciding which of those sizes matches the truck's current wheel setup and the type of driving or appearance you want. A truck kept in a more traditional format may suit 6.00-14, while 195R14 or ER70-14 may be the better direction for a radial-equipped setup with a more road-oriented or vintage-styled presentation.
What size rim does a 1980 Mazda Trucks B2000 use?
The tire sizes associated with the 1980 Mazda Trucks B2000 all use a 14-inch rim diameter. That includes 195R14, 6.00-14, and ER70-14, so wheel diameter stays consistent even though the tire sizing systems and constructions differ.
That consistency simplifies fitment, but it does not mean every 14-inch wheel is automatically suited to every tire option. Wheel width, the truck's current wheel type, and any past modifications still matter, especially when moving between a numeric bias-ply size and a radial size with a different shape and intended presentation.
Do all 1980 Mazda Trucks B2000 sub-models use the same tire size?
The Base, Sundowner, and Sundowner Sport all share the same three tire sizes for the 1980 model year: 195R14, 6.00-14, and ER70-14. There is no separate tire-size split here that forces a different choice by sub-model alone.
That means the more important check is the truck itself rather than the badge on the fender. Confirm the actual wheels currently installed, then choose the size and construction that fit the truck's condition, appearance goals, and intended use, especially if it has been updated over the years with different wheels or suspension parts.
Choosing the Right Tire
What should I consider when choosing a tire for a 1980 Mazda Trucks B2000?
Start with the correct 14-inch size and then narrow the choice by construction. The 1980 Mazda Trucks B2000 can use 195R14 radial, 6.00-14 bias-ply, or ER70-14 radial, so the real decision is whether the truck should keep a traditional bias-ply format or use a radial option.
After that, compare the truck's actual wheel setup, the look you want, and how the vehicle will be driven. A restoration-minded pickup may lean toward the numeric bias-ply format, while a radial choice may better suit regular road use or a more performance-inspired vintage appearance. Sidewall treatment can also shape the truck's final look.
What sidewall styles are available for 1980 Mazda Trucks B2000 tires?
Among the available 1980 Mazda Trucks B2000 product choices, ER70-14 is offered with Redline and RWL sidewall styles. Both appear in Firestone's Wide Oval Radial line, giving this truck two distinct vintage-style visual directions within the same size.
That matters most when the truck's appearance is part of the decision rather than size alone. Redline creates a more deliberate accent, while raised white letter styling gives the sidewall a stronger performance-era look. Either way, sidewall treatment should come after confirming the right size and construction for the wheels actually on the truck.
What brands offer tires for the 1980 Mazda Trucks B2000?
Firestone is represented in the current 1980 Mazda Trucks B2000 product selection through the ER70-14 size. The available tire series is the Firestone Wide Oval Radial, offered with different sidewall presentations in the same size and 14-inch rim format.
Brand is only one part of the decision, especially on a truck with more than one correct size. It still makes sense to start by confirming whether your B2000 is staying with a bias-ply style or moving toward a radial format, then compare the available series and sidewall options within the size that best matches the truck's setup.
Restoration & Appearance
Which tire should I choose for a period-style 1980 Mazda Trucks B2000?
A period-style 1980 Mazda Trucks B2000 can reasonably start with either the 6.00-14 bias-ply size or the ER70-14 radial, depending on the look and driving character you want. The numeric bias-ply format leans more traditional, while ER70-14 keeps a vintage visual character in a radial construction.
The right choice depends on how strictly the truck is being presented and how it will be used on the road. Buyers pursuing a very traditional stance often look closely at bias-ply sizing, while those wanting a vintage appearance with radial construction may prefer ER70-14. For exact originality, vehicle-specific historical references remain important.
How does tire construction affect the appearance of a restored 1980 Mazda Trucks B2000?
Tire construction changes more than ride feel on a restored 1980 Mazda Trucks B2000; it also influences the truck's overall visual character. A 6.00-14 bias-ply carries an older sizing format and traditional presentation, while radial choices such as 195R14 or ER70-14 give the truck a different stance and sidewall profile.
That visual difference is especially noticeable on a compact pickup with simple body lines and modest wheel openings. Sidewall treatment can push the appearance further, particularly with ER70-14 options in Redline or RWL form. Matching construction to the restoration goal usually creates a more coherent result than choosing by size code alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1980 Mazda Trucks B2000?
Yes. Even though the 1980 Mazda Trucks B2000 uses 14-inch tire sizes, modifications can change how well a given tire works on the truck. Aftermarket wheels, altered wheel width, suspension changes, lowering, or bodywork can all affect clearance and the way a radial or bias-ply tire sits.
A B2000 that no longer has its original-style wheel and suspension setup should be checked carefully before a tire is chosen. Steering clearance, fender space, and the wheel's actual dimensions matter just as much as the size molded on the sidewall. That is especially true when comparing 6.00-14 with the truck's radial options.
What should I inspect before driving a 1980 Mazda Trucks B2000 on new tires?
Before putting a 1980 Mazda Trucks B2000 back into service on new tires, inspect the wheels for damage, confirm the rim diameter, and make sure the wheel width suits the tire being installed. It is also wise to check suspension condition, steering components, and basic alignment-related wear points.
After installation, keep an eye on inflation pressure, bead seating, and early signs of rubbing during full steering lock or suspension movement. A short local test drive can reveal issues that are not obvious in the garage. Older compact trucks often have seen years of repairs and changes, so a careful first inspection is worthwhile.
How should tires on a collector 1980 Mazda Trucks B2000 be maintained?
Tires on a collector 1980 Mazda Trucks B2000 should be inspected regularly for cracking, cuts, bulges, uneven wear, and air loss, even if the truck is only driven occasionally. Low annual mileage does not prevent age-related tire deterioration, so appearance and pressure checks still matter.
Storage conditions also play a big role in tire life on an older pickup. Keeping the truck away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires between drives. It also makes sense to recheck pressure and general condition before any longer trip, rather than assuming a lightly used truck is road-ready.
