Radial vs Bias Ply Lawn Tractor Tires: Which One Should You Buy?
Radial and bias ply lawn tractor tires compared through a radial example and a bias ply example, with a listing contradiction noted.
On this page
Verdict: Choose a radial tire if you want the clearly stated radial construction and load and speed ratings of the Kenda example. Choose the Carlstar example only after checking its listing closely, since its title and a bullet disagree on construction.
A lawn tractor that slips on soft ground or leaves torn turf behind turns a routine mow into a repair job, and the tire is often the part that decides it. The radial vs bias ply lawn tractor tires question comes down to construction, size, load ratings and tread, and this comparison works through those points with an example from each side.

Kenda K500 Super Turf 20X10.50R8 4 Ply Radial Tire
A radial lawn and garden tractor tire, size 20X10.50R8, 4 ply, with Load Index 86 and Speed Rating A3, for all season traction.
Read the full review
The Kenda K500 Super Turf is the radial example, and its listing is the clearer of the two on ratings: a 20X10.50R8 size, 4 ply rating, radial construction, a black sidewall and all season traction for lawn mower and garden tractors. Load Index 86 is stated to support up to 1168 lbs per tire, and Speed Rating A3 is stated as certified to 9 mph. The item weight is stated as 15.0 Pounds, with dimensions of 19.0 Inches x 19.0 inches x 9.0 inches.
The listing states tire only, with rim and wheel not included, so a rim must already be on hand. No warranty term is stated, and no tread detail beyond all season traction is stated. The smaller stated size than the Carlstar example means the size marking must be checked against the tractor manual.
Pros
- Radial construction clearly stated
- Load Index 86 supporting up to 1168 lbs per tire stated
- Speed Rating A3 certified to 9 mph stated
- All season traction stated for lawn mower and garden tractors
Cons
- No warranty term is stated
- No tread detail beyond all season traction is stated
- Rim and wheel are not included
- Smaller stated size at 20X10.50R8 than the Carlstar example
Carlstar Versa Turf 24X12.00R12 Lawn and Garden Tire
A lawn and garden tractor tire, size 24X12.00R12, 4 ply, with a deep tread pattern, self-cleaning bars and rounded shoulders.
Read the full review
The Carlstar Versa Turf is the example on the bias ply side of this comparison, but its listing disagrees with itself: the title states 4 Ply Bias Construction, while a bullet in the same listing states radial construction. The listing also notes that Carlisle branded tires are now Carlstar. Beyond the conflict, the listing states a 24X12.00R12 size, a deep tread pattern great for soft soil or turf, self-cleaning bars that eject mud and grass, and rounded shoulders that enhance maneuverability. The item weight is stated as 26.6 pounds.
A 99A4 marking is stated with no load or speed figure attached, so no load or speed claim follows from it. The warranty description states a Standard Manufacturer Warranty with no term stated, and no rim detail is stated either way. The listing does not rank its title over its bullet, so the conflict stands and the listing leaves construction unclear.
Pros
- Deep tread pattern stated as great for soft soil or turf
- Self-cleaning bars eject mud and grass for consistent traction
- Rounded shoulders stated to enhance maneuverability
- All season traction stated for lawn mower and garden tractors
Cons
- Title states bias construction while a bullet states radial construction
- No load or speed figure is stated for the 99A4 marking
- No warranty term is stated; Standard Manufacturer Warranty only
- Rim detail is not stated

Construction stated in the listings
The Kenda example states radial construction plainly, with a black sidewall and all season traction for lawn mower and garden tractors. The Carlstar example does not settle construction: its title states 4 Ply Bias Construction, while a bullet in the same listing states radial construction. Those two statements cannot both describe the construction, so the Carlstar listing leaves construction unclear, and no side win on construction follows from it. Neither listing states ride, comfort or handling differences between constructions, so this comparison claims none.
Size and load ratings
The stated sizes differ: the Kenda example is 20X10.50R8, and the Carlstar example is 24X12.00R12. Only the Kenda listing states load and speed figures, with Load Index 86 supporting up to 1168 lbs per tire and Speed Rating A3 certified to 9 mph. The Carlstar listing states a 99A4 marking with no load or speed figure attached, so no load or speed comparison between the examples is possible. Weights also differ, at 15.0 Pounds for the Kenda example and 26.6 pounds for the Carlstar example, but the sizes differ too, so weight does not settle a side win.
Tread and traction
Tread detail is stronger on the Carlstar example. Its listing states self-cleaning bars within the tread that eject mud and grass for consistent traction, a deep tread pattern stated as great for soft soil or turf, and rounded shoulders stated to enhance maneuverability. The Kenda listing states all season traction without tread detail beyond that. On tread description alone, the Carlstar example gives the buyer more to work with, while the Kenda example gives the clearer load and speed figures.
What is included
The Kenda listing states tire only, with rim and wheel not included, so a buyer needs a rim already. The Carlstar listing states no rim detail either way. On warranty, the Kenda listing states no warranty term, and the Carlstar listing states a Standard Manufacturer Warranty with no term stated, so neither example scores for warranty here.

- Size match: the Kenda example is 20X10.50R8 and the Carlstar example is 24X12.00R12, so check the size marking against the tractor manual before ordering.
- Soft soil or turf: the Carlstar listing states a deep tread pattern for soft soil or turf, with rounded shoulders for maneuverability.
- All season use: the Kenda listing states all season traction for lawn mower and garden tractors.
- Rim planning: the Kenda listing states tire only, with rim and wheel not included.
The Acre Score explained
The Acre Score weighs performance, build, value, safety and warranty from each listing. Safety scores only where the listing states a safety feature, and warranty scores only where the listing states a concrete term. Neither listing states a safety feature or a concrete warranty term, so both score zero on those factors, and the ranking rests on stated performance, build and value.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Kenda K500 Super Turf | 9.6 | 29 | 21 | 20 | n/a | 0 |
| Carlstar Versa Turf | 9.6 | 28 | 20 | 20 | n/a | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
Never mow a slope steeper than the maximum your manual lists, and mow up and down slopes rather than across. Use the ROPS and seat belt where the machine has them (follow the manual on when a folding ROPS may be lowered), never carry passengers, keep children and pets out of the yard while you mow, and disengage the blades before reversing. Refuel only with the engine off and cool. See CPSC riding lawnmower safety. Read our Safety Disclaimer.
FAQ: mowing large lots
Which side suits soft soil or turf?
The Carlstar listing states a deep tread pattern great for soft soil or turf, with self-cleaning bars that eject mud and grass. The Kenda listing states all season traction without tread detail, so the tread description favors the Carlstar example while load ratings favor the Kenda example.
Why does the Carlstar listing disagree with itself?
Its title states 4 Ply Bias Construction, while a bullet in the same listing states radial construction. The listing does not resolve the conflict, so construction for that example stays unclear until the seller clarifies it.
What load and speed do these tires state?
The Kenda example states Load Index 86 supporting up to 1168 lbs per tire, with Speed Rating A3 certified to 9 mph. The Carlstar example states a 99A4 marking with no load or speed figure attached.
Does either tire include a rim?
The Kenda listing states tire only, with rim and wheel not included. The Carlstar listing states no rim detail either way.
What warranty do these tires carry?
The Kenda listing states no warranty term. The Carlstar listing states a Standard Manufacturer Warranty with no term stated, so neither example carries a stated warranty term.
