1970 Toyota Mark II Tires

A 1970 Toyota Mark II uses two primary tire sizes: 165R13 in radial construction and 600-13 in bias-ply construction. Both sizes are associated with the Sedan & Wagon application and both fit 13-inch wheels, so the fitment question is less about wheel diameter and more about which tire type matches the car and the owner's goals.

That means the next step is confirming the actual wheel width on the car and deciding whether a traditional bias-ply presentation or a radial setup makes more sense. Cars with replacement wheels, suspension changes, or long-ago tire conversions should be checked carefully before ordering by size alone.

The primary tire fitments for the 1970 Toyota Mark II use a 13-inch rim diameter. Both 165R13 and 600-13 are built around that same wheel diameter, which keeps the rim-size side of the decision simple compared with vehicles that changed diameters across trims or options.

Rim diameter is only part of the fitment picture, though. Wheel width still matters, especially when comparing a 600-13 bias-ply tire with a 165R13 radial or with one of the radial equivalents tied to the 600-13 size. Measuring the wheel already on the car is a smart step before making a construction change.

The 1970 Toyota Mark II Sedan & Wagon shares the same covered tire-size choices: 165R13 radial and 600-13 bias-ply. That means the sub-model does not force a different rim diameter or a separate tire family, which simplifies the selection process for owners of those body styles.

The real distinction is choosing the tire construction and appearance that suit the car. A radial selection points you toward blackwall options in a more modern construction style, while 600-13 bias-ply tires keep the older sizing system and offer whitewall treatments that may better suit a restoration-oriented presentation.

For the 1970 Toyota Mark II, 600-13 is a bias-ply tire size. It uses the older numeric sizing system, and the available 600-13 options follow that traditional bias-ply construction rather than a radial design. By contrast, 165R13 is the radial-format primary fitment on the same 13-inch rim diameter.

That difference affects both appearance and setup. A 600-13 choice keeps the vintage bias-ply style and currently appears with whitewall sidewall treatments, while a 165R13 radial points toward blackwall options. Before changing constructions, verify wheel width and make sure the car's steering and suspension clearances are still appropriate.

Radial equivalents for 600-13 include 165R13 as an 80-series metric radial, P165/75R13 as a P-metric 75-series radial, and P175/70R13 as a P-metric 70-series radial. Those are the usable radial alternatives tied to the original 600-13 sizing, and the recommended rim-width range attached to those equivalents is 4-5 inches.

Each equivalent uses the same 13-inch rim diameter, but that does not make every option automatic for every car. Wheel width, tire dimensions, and clearance at the fender and steering points should still be checked, especially on a Mark II that may have been altered over time or no longer carries its original wheel setup.

Start by confirming the wheel diameter and width, then compare the intended radial size with the tire currently on the car. For a 600-13 Toyota Mark II, the radial alternatives include 165R13, P165/75R13, and P175/70R13, so the conversion question is really about matching the wheel and the car's available space to the chosen equivalent.

Road-use plans matter too. A car built for preservation may favor staying with bias-ply styling, while a driver may lean toward radial construction. It is also wise to inspect suspension condition, steering travel, and fender clearance before changing sizes or constructions, particularly if the car has aftermarket wheels or altered ride height.

The first choice is selecting the correct size and construction for the way the car will be used. A 1970 Toyota Mark II can be kept in 600-13 bias-ply form or fitted with 165R13 radial tires, so the decision usually comes down to vintage presentation versus radial-format road use, while staying on a 13-inch rim.

After that, compare wheel-width compatibility, sidewall style, brand, and tire series. A whitewall bias-ply tire creates a very different appearance from a blackwall radial, and the car's actual wheels should be measured before making the final pick. Intended use, storage habits, and how original the vehicle remains also deserve consideration.

Sidewall style depends on the size and construction you choose for the 1970 Toyota Mark II. The 165R13 radial options are blackwall tires, while the 600-13 bias-ply choices are available with wide whitewall and narrow whitewall treatments. That gives the car very different visual directions even while staying within the proper fitment family.

A blackwall radial generally suits an owner focused on a cleaner radial presentation, while whitewall bias-ply tires move the car toward a more traditional period-style look. Sidewall appearance should be chosen alongside wheel width and overall tire construction, not as a separate cosmetic decision disconnected from fitment.

Michelin, Dunlop, and BFGoodrich all have applicable tire choices for the 1970 Toyota Mark II. Michelin and Dunlop cover the 165R13 radial side with blackwall options, while BFGoodrich covers the 600-13 bias-ply side through the Silvertown Classic Bias Ply series with whitewall variations.

Brand should be considered together with size, construction, and appearance rather than in isolation. The useful comparison is whether you want a radial or bias-ply tire first, then which sidewall style and tire series fit the car's look and intended use. Wheel-width compatibility is still one of the most important checks before deciding.

For a period-style 1970 Toyota Mark II, the 600-13 bias-ply size is the natural starting point because it keeps the older numeric sizing format and traditional construction style. Available choices in that size include whitewall variations, which can help create a more restoration-oriented appearance than a modern-looking blackwall radial.

Appearance goals still need to be balanced with how the car will actually be driven. Some owners prioritize vintage character, while others want a radial-format alternative for regular road use. When exact originality matters, period photos, marque references, and vehicle-specific historical sources are worth reviewing before settling on a sidewall treatment.

Tire construction changes the visual character of a restored 1970 Toyota Mark II more than many owners expect. A 600-13 bias-ply tire keeps the older size format and is available with whitewall styling, while the 165R13 radial choices are blackwall tires with a more modern construction presentation even though they share the same 13-inch rim diameter.

That makes construction an appearance decision as well as a fitment decision. Bias-ply tires usually support a more traditional profile and restoration-minded look, while radial tires can shift the car toward a later-service replacement feel. Matching the tire to the car's wheels, trim level of finish, and use pattern produces a more coherent result.

Yes, modifications can affect tire fitment on a 1970 Toyota Mark II even when the car stays within the correct 13-inch rim diameter. Aftermarket wheels, different wheel widths, suspension changes, lowering, or body modifications can alter how a 165R13, 600-13, or radial equivalent sits in the wheel opening and turns through its steering range.

That is why an older car should never be fitted by catalog size alone if it has been changed over time. Checking wheel width, clearance at full steering lock, and space around the fender and suspension helps prevent surprises. A Mark II with non-original wheels deserves especially careful measurement before any construction or equivalent-size change.

Before driving a 1970 Toyota Mark II on new tires, inspect the wheels for the correct diameter and condition, confirm proper tire pressure, and make sure there is no rubbing during steering or suspension movement. It is also wise to look over the suspension, alignment condition, and valve stems so the new tires are not being asked to work around an existing problem.

A short initial road test is a smart follow-up. Listen for rubbing, feel for unusual pull or vibration, and recheck inflation after the first drives. Collector cars that have sat for long periods should also have brakes, wheel bearings, and steering components inspected so the tire change is part of a safer return to road use.

Collector-car tires on a 1970 Toyota Mark II should be checked regularly for pressure loss, cracking, cuts, bulges, uneven wear, and signs of age even if the car is driven only occasionally. Low annual mileage does not prevent tire aging, so visual inspection matters just as much as tread depth on a vehicle that spends much of its life parked.

Storage conditions also play a major role. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires between drives. Rolling the car occasionally, maintaining inflation, and inspecting the spare and road tires before longer outings will help an infrequently used Mark II stay more road-ready.
