Avon CR6ZZ | 225/65R15 99V A29

The Avon CR6ZZ 225/65R15 99V fits 15-inch wheels within the published 6.0-to-8.0-inch rim-width range. A 15-inch diameter marking by itself is not enough because wheel width, bead-seat condition, offset, backspacing, and load capacity all affect safe installation.

Measure wheel width at the bead seats rather than across the outer lips. Confirm that the wheel is suitable for tubeless use and that its valve, barrel, and bead areas are undamaged. Wheel offset must also position the tire’s 9.09-inch section width clear of the body, steering, brakes, and suspension.

The Avon CR6ZZ 225/65R15 99V may fit an unmodified classic performance car when its dimensions closely match the original or currently fitted tire. The tire measures 26.70 inches tall and 9.09 inches across the section, making it substantially wider than many narrow factory tires used on earlier vehicles.

Check inner and outer clearance before assuming a stock fit. Wheel offset, axle width, ride height, steering geometry, and prior repairs can change available space. The tire must clear the fender lip, springs, control arms, shocks, and frame throughout steering travel and suspension compression, not only while parked.

There is no single vintage numeric or alpha-numeric size that can be treated as an exact equivalent to the Avon CR6ZZ 225/65R15 99V. Older sizing systems describe tires differently and may produce another casing shape, tread width, load capacity, or installed section width.

Compare actual dimensions instead of relying on a conversion chart alone. The Avon measures 26.70 inches in diameter, 9.09 inches across the section, and 7.17 inches across the tread. Also compare the 6.0-to-8.0-inch wheel range, load index 99, radial construction, and V speed rating before selecting it as a replacement.

The Avon CR6ZZ 225/65R15 99V can change speedometer and odometer accuracy when its 26.70-inch diameter differs from the tire used to calibrate the vehicle. A taller tire usually makes the indicated speed lower than actual road speed, while a shorter tire usually makes the indicated speed higher.

The PDP lists 755 revolutions per mile, which can be compared directly with the current tire’s figure. The percentage difference provides a practical estimate of the resulting error. Mechanical speedometer gears or electronic calibration may require adjustment after installation, particularly on a modified drivetrain or a vehicle converted from a vintage tire size.

Compare the Avon CR6ZZ 225/65R15 99V with the current tire using overall diameter, section width, tread width, wheel-width range, load index, speed rating, and construction. The Avon measures 26.70 inches tall, 9.09 inches across the section, and 7.17 inches across the tread.

Also compare its 755 revolutions per mile, 65-series profile, tubeless radial design, and 6.0-to-8.0-inch wheel requirement. A similarly labeled vintage or competition tire may still mount and behave differently. Confirm body clearance, axle load, wheel compatibility, and speedometer effects before treating any nominal size as a direct replacement.

The Avon CR6ZZ 225/65R15 99V is a road-legal racing tire developed for classic performance vehicles that divide time between street and track use. Its radial construction and all-weather tread pattern are intended to provide stable road manners, strong grip, and effective water evacuation during normal driving.

The sticky compound and UTQG treadwear rating of 80 indicate a performance-focused design rather than a long-mileage touring tire. Expect responsive grip but potentially faster wear than a conventional street radial. Ride quality, steering effort, and noise will still depend on inflation pressure, wheel width, alignment, suspension condition, and vehicle weight.

The Avon CR6ZZ 225/65R15 99V is DOT approved and carries a V speed rating, indicating standardized capability up to 149 mph under specified test conditions. Its radial casing should provide stable highway behavior when the tire is correctly loaded, inflated, aligned, and mounted.

A V rating is not a recommended cruising speed, especially on a historic vehicle. Extended highway operation creates heat, and the UTQG temperature grade is B rather than the highest A grade. Use conservative speeds, verify cold pressure, and inspect the tire during long trips. Vehicle brakes, suspension, wheels, and aerodynamics may impose much lower limits.

The Avon CR6ZZ 225/65R15 99V is hand-built for classic vehicles that share time between street and track, but durability should be judged as performance-tire durability rather than touring-tire longevity. The UTQG treadwear rating of 80 indicates a soft compound that prioritizes grip.

Hard cornering, repeated heat cycles, aggressive alignment, and track temperatures can accelerate wear even when tread depth appears adequate. Inspect for shoulder wear, heat checking, cracking, flat spots, cuts, and changes in grip. Record track sessions and tire age, and replace the tire based on condition and performance consistency rather than waiting only for the tread to reach a legal minimum.

The Avon CR6ZZ 225/65R15 99V is approved for 6.0-to-8.0-inch wheels. Wheel width influences casing shape, sidewall support, steering response, and how the 7.17-inch tread sits against the road. A wider approved wheel generally supports the sidewall more firmly, while a narrower wheel creates more curvature.

Inflation pressure controls how load is distributed through the contact patch. Excess pressure can concentrate load toward the tread center, while insufficient pressure can increase shoulder loading, flex, and heat. Stay within the approved wheel range and use pressure guidance based on vehicle load and intended use rather than appearance alone.

The Avon CR6ZZ 225/65R15 99V is listed as tubeless, so it can be installed without an inner tube on a compatible airtight 15-inch wheel. The wheel must have the correct bead-seat design, approved width, undamaged sealing surfaces, and a suitable tubeless valve.

Some classic wire, riveted, split, or corroded wheels may not retain air safely without additional approved hardware or a tube. Do not add a tube automatically, because high-performance radial service may require a specific tube and installation procedure. Have the wheel evaluated by a vintage tire specialist when its tubeless compatibility is uncertain.

Store the Avon CR6ZZ 225/65R15 99V in a cool, dry, dark environment away from ozone sources, electric motors, solvents, petroleum products, and direct sunlight. Clean the tires and wheels before storage and maintain appropriate pressure if they remain on the vehicle.

For long storage, reduce concentrated loading by using suitable tire supports or safely unloading the vehicle according to the storage plan. Avoid leaving the same contact area heavily loaded for months. Before returning to service, inspect pressure, tread, sidewalls, valves, and bead areas. Build speed gradually and investigate persistent vibration rather than assuming every flat spot is temporary.
