Carlisle Turf Trac R/S Lawn & Garden Bias Tire- 22.5X10.00-8NHS/4 00

What It Is

The Carlisle Turf Trac R/S is a bias-ply lawn and garden tire (22.5x10.00-8, NHS/4PR) designed for rear-wheel drive on zero-turn mowers, garden tractors, and larger riding mowers. Its “R/S” (Rib/Sawtooth) tread pattern balances turf-friendly traction with stability on slopes and wet grass.

Fitment & Compatibility

• Measure your rim: Requires an 8-inch diameter rim with a 4.00-inch width (4.00-8 rim). Verify rim width – a 4.5-inch rim may work but can alter profile.
• Check tire size: 22.5x10.00-8 is the overall diameter (22.5″) and section width (10″). Compare to your current tire’s sidewall markings. Common alternatives: 23x10.50-12 (different rim size) or 22x11.00-8 (slightly shorter, wider).
• Load capacity: NHS (Not for Highway Service) rating; 4-ply rating (4PR) supports up to ~1,100 lbs per tire at 20 PSI. Confirm your machine’s rear axle weight doesn’t exceed this.
• Model/brand fit: Fits most zero-turn mowers (e.g., Toro TimeCutter, John Deere Z-series, Husqvarna Z400) and garden tractors with 8″ rims. Not for front steer tires (different tread pattern).
• OEM vs aftermarket: Direct replacement for Carlisle OEM tires on many commercial mowers. No modification needed if rim size matches.

Key Things to Know

• Bias vs radial: Bias-ply is stiffer, better for heavy loads and rough terrain, but rides harsher than radial tires. Good for mowers with high rear weight.
• Installation: Requires tire irons and a bead seater; not a quick swap. Tubeless design – check rim for rust or damage before mounting. Use a tire lubricant to avoid bead damage.
• Tread life: Rib/sawtooth design wears faster on pavement but grips well in grass and light mud. Rotate side to side if uneven wear appears.
• PSI range: Recommended 14-20 PSI. Overinflating reduces traction and can cause a bouncy ride; underinflating risks rim damage.

Should You Buy It

If you need a durable, turf-friendly rear tire for a zero-turn or garden tractor on 8″ rims, this is a solid choice at a fair price. It’s not for high-speed road use or soft, sandy soil, but for typical lawn care on slopes or damp grass, it delivers reliable grip and load support.
