1991 Chevrolet Minivans covered two very different family hauler ideas: the futuristic front-drive APV and Lumina APV, and the more traditional rear-drive Astro. That spread matters because Chevrolet was serving buyers who wanted either car-like packaging or a tougher van-based platform, and the tire sizes reflect those different missions. Across the 1991 Chevrolet Minivans range, three models use five radial sizes, with the APV and Lumina APV sharing one 14-inch fitment while Astro and Lumina APV also branch into separate 15-inch sizes. The first thing to confirm before choosing a tire is your exact model, then whether your van uses a 14-inch or 15-inch wheel.
Which Tire Size Is Right for Your 1991 Chevrolet Minivans
Five tire sizes cover 1991 Chevrolet Minivans, and they vary by model rather than carrying across the full range. The main decision is confirming the correct model and wheel diameter first, since the APV, Lumina APV, and Astro do not all use the same rim size. Understanding that distinction before choosing a product saves time and helps match the tire to the right van.
Year(s): 1991|Fit(s): APV, Lumina APV|Construction: Radial|Rim: 14 in
205/70R14 is a radial metric size with a 205-millimeter section width, a 70-series aspect ratio, and a 14-inch rim diameter. This size is available from Maxxis and BFGoodrich in Narrow Whitewall, RWL, Dual-Redline, and Redline sidewall styles, with an S speed rating appearing on some products at 112 mph. Because it is specific to the APV and Lumina APV rather than the full Chevrolet minivan range, it is the right starting point for those front-drive vans. Buyers usually choose within this size based on whether they want a more factory-style whitewall look or a sportier period sidewall treatment.
Year(s): 1991|Fit(s): Astro|Construction: Radial|Rim: 15 in
205/75R15 is a radial metric size with a 205-millimeter section width, a 75-series aspect ratio, and a 15-inch rim diameter. BFGoodrich, Tornel, and American Classic offer this size with Wide Whitewall, Goldline, and Narrow Whitewall sidewall styles. This Astro-specific size suits owners who want a relatively stock-appearing 15-inch fitment with classic sidewall choices. It is a practical match when preserving a more traditional van look matters as much as staying with the correct overall size family.
Year(s): 1991|Fit(s): Astro|Construction: Radial|Rim: 15 in
215/75R15 is a radial metric size with a 215-millimeter section width, a 75-series aspect ratio, and a 15-inch rim diameter. This Astro-only size is available from BFGoodrich, Coker Classic, and Tornel in RBL, Narrow Whitewall, and Wide Whitewall styles, and some products carry an S speed rating at 112 mph while others do not show a speed symbol. For Astro owners, it offers another 15-inch fitment path with a broader mix of classic and utility-oriented sidewall treatments. It is the size to consider when your van is set up for the wider 215-section tire rather than the narrower 205-section option.
Year(s): 1991|Fit(s): Astro|Construction: Radial|Rim: 15 in
245/60R15 is a radial metric size with a 245-millimeter section width, a 60-series aspect ratio, and a 15-inch rim diameter. Cooper, Avon, and BFGoodrich offer it in RWL and Blackwall styles, and speed ratings vary by product, including S at 112 mph and V at 149 mph. This size is specific to Astro and points toward a much wider, more performance-flavored 15-inch setup than the van's narrower stock-style choices. It generally appeals to owners building a custom street look rather than chasing a conservative original-style appearance.
Year(s): 1991|Fit(s): Lumina APV|Construction: Radial|Rim: 15 in
205/65R15 is a radial metric size with a 205-millimeter section width, a 65-series aspect ratio, and a 15-inch rim diameter. BFGoodrich offers this size in Wide Whitewall and Redline versions. Because it is unique to Lumina APV within the 1991 Chevrolet Minivans range, it should be chosen only after confirming that your van uses the 15-inch wheel package rather than the shared 14-inch APV-style fitment. It is a natural choice for owners balancing the Lumina APV's modern early-1990s shape with a period-appropriate reproduction radial.
Three Chevrolet minivan models are covered for 1991, and they do not all use the same tire sizes. That means year and make alone are not enough here; buyers need to identify whether they have an APV, Astro, or Lumina APV before choosing a size. Select a model below to narrow the fitment history and see the tire choices that apply to that van.
1991 Chevrolet Minivans APV
The APV was Chevrolet's sharply styled front-drive people mover, part of GM's effort to rethink the family van for the 1990s with a lower, more aerodynamic shape. Its tires mount on 14-inch wheels in this application, which gives APV owners a more focused fitment path than Astro buyers face. Sidewall style and overall visual character tend to be the bigger choice once the correct size is confirmed.
The Astro took a different approach from the APV family, using a more conventional van layout that appealed to buyers who wanted utility, towing confidence, or a tougher stance. Its tires mount on 15-inch wheels, and Astro fitment spans three distinct sizes from stock-style proportions to a much wider custom-oriented option. That makes model identification especially important before comparing sidewall style or brand.
The Lumina APV shared GM's futuristic minivan architecture but carried Chevrolet's mainstream family-vehicle identity in a package that felt more car-like than a traditional van. Its fitments span both 14-inch and 15-inch wheels, so wheel diameter needs to be confirmed before moving on to brand or sidewall details. That split makes the Lumina APV the most size-sensitive model in the 1991 Chevrolet minivan lineup.
Twenty-one products are available across five tire sizes for 1991 Chevrolet Minivans vehicles. 205/70R14 includes 4 products from Maxxis and BFGoodrich in radial form with Narrow Whitewall, RWL, Dual-Redline, and Redline styles; 205/75R15 includes 4 from BFGoodrich, Tornel, and American Classic with Wide Whitewall, Goldline, and Narrow Whitewall styles; 215/75R15 includes 4 from BFGoodrich, Coker Classic, and Tornel with RBL, Narrow Whitewall, and Wide Whitewall styles; 245/60R15 includes 3 from Cooper, Avon, and BFGoodrich with RWL and Blackwall styling; 205/65R15 includes 2 from BFGoodrich with Wide Whitewall and Redline styling. Confirm your model, wheel diameter, and preferred sidewall style before selecting.
These answers sort out which sizes belong to APV, Astro, and Lumina APV, how the different 14-inch and 15-inch fitments relate to each other, and what sidewall styles, setup details, and long-term care matter for a 1991 Chevrolet minivan.
Size Basics & Fitment
What tire sizes fit 1991 Chevrolet Minivans vehicles?
1991 Chevrolet Minivans use five sizes across three models. The APV uses 205/70R14, the Astro uses 205/75R15, 215/75R15, and 245/60R15, and the Lumina APV uses 205/70R14 and 205/65R15. Rim diameters are either 14 inches or 15 inches depending on model and setup. Rim width ranges also vary by size, with 205/70R14 typically fitting 5.00 to 7.50-inch rims, 205/75R15 and 205/65R15 fitting about 5.50 to 7.50-inch rims, 215/75R15 fitting about 5.5 to 7.5-inch rims, and 245/60R15 fitting 7.0 to 8.5-inch rims.
The practical takeaway is that year and make alone are not enough for a 1991 Chevrolet minivan. APV and Lumina APV overlap on one 14-inch size, but Astro stays entirely in 15-inch fitments, and Lumina APV can also use a different 15-inch size. Before choosing a tire, confirm the exact model and then verify the wheel diameter on the van itself. That avoids mixing a 14-inch front-drive APV-type fitment with a 15-inch Astro or Lumina APV application.
What does 205/70R14 mean on a 1991 Chevrolet Minivans tire?
On a 1991 Chevrolet Minivans tire, 205/70R14 is a metric radial size. The 205 is the nominal section width in millimeters, 70 is the aspect ratio, R means radial construction, and 14 is the wheel diameter in inches. Within the Chevrolet minivan range for 1991, that size fits the APV and also appears on some Lumina APV applications. Available versions include classic whitewall styles as well as RWL, redline, and dual-redline variations.
That code matters because it tells you both the wheel diameter and the tire's general profile. A buyer with an APV or Lumina APV should use 205/70R14 only when the van is actually on 14-inch wheels, then choose among the available sidewall styles based on the look they want. If your Lumina APV wears 15-inch wheels instead, the correct fitment path changes completely. Reading the sidewall code before ordering is the fastest way to avoid crossing over between the two wheel packages.
Do all 1991 Chevrolet Minivans models use the same tire size?
No, 1991 Chevrolet Minivans models do not all use the same tire size. The APV uses only 205/70R14, the Astro uses three 15-inch sizes, and the Lumina APV can use either 205/70R14 or 205/65R15 depending on the wheel setup. That means there is overlap between APV and Lumina APV, but no single size covers the full Chevrolet minivan lineup for 1991.
This affects tire selection more than almost any styling preference on the page. An Astro owner needs to stay within the 15-inch Astro group, while a Lumina APV owner needs to confirm whether the van carries the shared 14-inch fitment or the separate 15-inch fitment. If you are unsure, check the existing sidewall size and the wheel diameter before comparing brands or sidewall treatments. That simple step narrows the choices quickly and keeps the search model-correct.
Buying the Right Tire
What sidewall styles are available for 1991 Chevrolet Minivans tires?
1991 Chevrolet Minivans tires come in a wide range of sidewall styles depending on size. 205/70R14 offers Narrow Whitewall, RWL, Dual-Redline, and Redline; 205/75R15 offers Wide Whitewall, Goldline, and Narrow Whitewall; 215/75R15 offers RBL, Narrow Whitewall, and Wide Whitewall; 245/60R15 offers RWL and Blackwall; and 205/65R15 offers Wide Whitewall and Redline. That gives Chevrolet minivan owners far more visual variation than a modern replacement-tire catalog usually does.
Choosing among those styles depends largely on the personality of the van and the look you want to preserve. Whitewalls generally suit family-oriented APV and Lumina APV restorations best, while RWL, RBL, or Blackwall styles make more sense for sportier or custom Astro builds. Redline and Goldline treatments are more specialized appearance choices and should be used when they match the theme of the vehicle. Sidewall style will not override the need to start with the correct size and wheel diameter.
What brands make tires for 1991 Chevrolet Minivans vehicles?
Several brands cover 1991 Chevrolet Minivans, but they do so by size rather than across the whole range. 205/70R14 comes from Maxxis and BFGoodrich; 205/75R15 comes from BFGoodrich, Tornel, and American Classic; 215/75R15 comes from BFGoodrich, Coker Classic, and Tornel; 245/60R15 comes from Cooper, Avon, and BFGoodrich; and 205/65R15 comes from BFGoodrich. Every one of those fits is radial, but the styling and character vary quite a bit from one brand family to another.
Brand choice is usually the second decision, not the first. Once you confirm the correct size for your APV, Astro, or Lumina APV, you can narrow by appearance, speed symbol where present, and the kind of period image you want the van to carry. Buyers looking for a stock-style whitewall will end up in a different part of the range than Astro owners chasing a broader custom street look. Comparing brands only makes sense after the fitment question is settled.
What is the difference between BFGoodrich Radial T/A and Avon CR6ZZ for a 1991 Chevrolet Minivans Astro using 245/60R15?
For a 1991 Chevrolet Minivans Astro in 245/60R15, the BFGoodrich Radial T/A and Avon CR6ZZ share the same 15-inch rim diameter and the same 7.0 to 8.5-inch rim-width range, but they differ in sidewall treatment and speed symbol. The BFGoodrich uses an RWL sidewall and carries an S speed rating with a 112 mph ceiling, while the Avon uses a Blackwall sidewall and carries a V rating with a 149 mph ceiling. The BFGoodrich also shows a 1,753-pound load figure at 35 psi.
That means the decision is less about basic fitment and more about presentation and intended road use. An owner who wants a classic raised-white-letter custom look will likely gravitate toward the BFGoodrich, while the Avon suits a cleaner blackwall appearance and carries a higher stated speed category. Either way, this is a wide Astro-specific size, so it belongs on the correct 15-inch wheel and should be matched to the van's setup rather than chosen only for appearance.
Fitting & Setup
What rim width do 1991 Chevrolet Minivans tires require?
Rim width requirements for 1991 Chevrolet Minivans depend on tire size. The 205/70R14 range spans 5.00 to 7.50 inches, 205/75R15 typically spans 5.50 to 7.50 inches, 215/75R15 runs about 5.5 to 7.5 inches, 245/60R15 requires 7.0 to 8.5 inches, and 205/65R15 spans 5.50 to 7.50 inches. The widest Astro fitment, 245/60R15, is the clear outlier because it needs a substantially wider wheel than the other Chevrolet minivan sizes.
That wheel-width difference is important when moving between stock-style and custom-style setups. A van that is correctly equipped for 205- or 215-section tires may not automatically be appropriate for a 245-section tire, even though both use 15-inch rims. Before ordering, verify the actual wheel width on the van rather than assuming every 15-inch Chevrolet minivan wheel is interchangeable. That is especially important on Astro builds that have been modified over time.
Do 1991 Chevrolet Minivans tires require inner tubes?
The available 1991 Chevrolet Minivans tire options are radial products without tube-type markings in their size descriptions. Some carry standard metric sizing such as 205/70R14 or 205/75R15, while others use P-metric notation such as P205/75R15 or P215/75R15, but none here are marked TT. That points buyers toward tubeless-style products rather than traditional tube-type collector-car tires.
Even so, the wheel still matters. If your van is on original factory wheels in sound condition, the next check is whether the wheel and valve-stem setup are suitable for modern tubeless service. A restored or repainted wheel should also be inspected for bead-seat condition before mounting. If there is any question about wheel integrity or sealing, have the wheel evaluated before fitting the tire instead of assuming the tire alone determines whether a tube is needed.
Maintenance, Storage & Longevity
How should I store a 1991 Chevrolet Minivans when the tires are fitted?
A 1991 Chevrolet Minivans should be stored away from direct sunlight, standing moisture, and ozone sources such as electric motors, battery chargers, or welders. Keep the tires clean, maintain inflation, and move the van periodically so one section of the tread is not carrying the load for months at a time. Because these are radial tires, they generally tolerate normal collector storage better than older bias-ply designs, but age and static loading still matter.
For a seasonal-use APV, Astro, or Lumina APV, the goal is to reduce environmental aging and prevent the tire from sitting stressed in one position too long. If the van will be parked for an extended stretch, rolling it occasionally or supporting it appropriately can help preserve shape and ride quality. A breathable cover for the whole vehicle is helpful, but the key tire threats remain UV exposure, ozone, and long periods of inactivity on one contact patch.
How long do tires on a 1991 Chevrolet Minivans typically last?
On a 1991 Chevrolet Minivans, tire life should be judged mainly by age and condition rather than mileage alone. Collector and hobby vehicles often wear out their tires chemically before they wear them out mechanically, so a good rule is to begin close inspection in the five- to seven-year range and give serious replacement consideration by around ten years regardless of tread depth. The DOT date code on the sidewall is the starting point for that age check.
A lightly used minivan can fool owners into thinking the tires are still fresh because the tread looks deep. What matters just as much is whether the rubber has hardened, cracked, or lost its ability to hold pressure and ride properly. If your APV, Astro, or Lumina APV spends most of its time parked, calendar age is more important than odometer miles. Treat tread depth as only one part of the decision, not the whole answer.
How often should tires on a 1991 Chevrolet Minivans be inspected?
Tires on a 1991 Chevrolet Minivans should be inspected before every drive and again before any longer highway outing. Check inflation, tread wear, sidewall cracking, cuts, bulges, and anything embedded in the tread. Since some of these vans may sit for long periods, also pay attention to whether the tires have developed flat-spotting or a habit of losing pressure while parked.
That routine matters even more on an older minivan that may carry passengers and cargo. An Astro set up with wider 245/60R15 tires should also be watched for uneven wear that can point to alignment or suspension issues, while APV and Lumina APV owners should keep an eye on age-related sidewall changes in their lower-profile metric radials. Make the spare part of the inspection too, because a thirty-year-old van often has an overlooked spare that is older than the four road tires.
Safety & Road Use
Are 1991 Chevrolet Minivans tires safe for highway driving?
1991 Chevrolet Minivans use radial tire options that are appropriate for regular road use when they are the correct size, in good condition, and inflated properly. Some sizes include products with an S speed rating, which carries a 112 mph ceiling, while the 245/60R15 range also includes a V-rated option with a 149 mph ceiling. Those figures are well above normal U.S. highway travel, so the van's age, maintenance, brakes, suspension condition, and load management usually matter more in real-world driving than raw tire speed category.
Safety comes from the whole package rather than the speed symbol alone. A fresh tire on a neglected Astro, APV, or Lumina APV does not overcome worn shocks, tired steering parts, or old brake components. Before longer highway use, match the tire to the correct wheel, inspect its age and condition, and be honest about how the van is maintained. Highway confidence in a 1991 Chevrolet minivan is as much about mechanical condition as tire specification.
What inflation pressure should I use for 1991 Chevrolet Minivans tires?
Inflation pressure for 1991 Chevrolet Minivans should start with the vehicle's factory recommendation, then be checked against the individual tire's own rated pressure and load information. Several tires in these sizes show maximum load and pressure pairings such as 1,433 pounds at 35 psi for 205/70R14, 1,598 pounds at 35 psi for 205/75R15, 1,742 to 1,874 pounds at 32 to 50 psi for 215/75R15 depending on product, 1,753 pounds at 35 psi for 245/60R15, and 1,400 pounds at 35 psi for 205/65R15. Those are maximum rated figures, not blanket running pressures for every van.
The important point is not to transfer one pressure figure from one size to another or from one product line to the next. A 215/75R15 Astro tire and a 205/65R15 Lumina APV tire do different jobs and can carry different maximum pressure/load pairings. Use the vehicle placard or owner's manual as the baseline, then confirm that the selected reproduction or specialty tire is being used within its own rating. If the van is carrying unusual cargo loads, reassess pressure with that use in mind.
What should I check before taking a 1991 Chevrolet Minivans on a longer drive?
Before taking a 1991 Chevrolet Minivans on a longer drive, inspect all four tires and the spare for cracking, cuts, tread separation, bulges, and proper inflation. Confirm that the tire size matches the wheel diameter, look for uneven wear that could suggest alignment or suspension issues, and inspect the valve stems as part of the pressure check. On a wide-tire Astro setup, also make sure there is no rubbing or clearance issue under load or at full steering lock.
Tires are only one part of preparing an older minivan for distance, but they are the part that most directly touches the road. Pair that inspection with a broader check of brakes, steering, cooling system, belts, and fluid levels before heading out. If the van has been parked for an extended period, give it a short local test drive first so you can feel for vibration, flat spotting, pull, or brake imbalance. Catching those issues early is far easier than troubleshooting them on the roadside.
