YINTATECH 18x8.50-8 Lawn Mower Tires Set of 2 — Tubeless 4-Ply, 7" Rim Fit for Turf Traction

These are YINTATECH 18x8.5-8 tubeless lawn mower tires (set of 2) with a 4-ply carcass and 7.1 mm tread depth designed for reliable traction on turf and light off-road surfaces.

Replacing worn mower tires with the right size and construction improves handling, turf protection, and durability. The YINTATECH 18x8.5-8 tires are built for 7" rims, offer a 4-ply rating with a reinforced 2-ply sidewall, and deliver deeper grooves and a directional shoulder pattern geared toward self-cleaning and grip across grass, dirt and gravel. They are tubeless replacements sold as a pair — rims not included — made for lawn and garden equipment rather than highway use.

Will these tires fit my riding mower or garden tractor?

Check the numbers on your existing tire sidewall and the rim width to confirm compatibility. These tires are sized 18x8.50-8 with an 8.2" section width and designed for 7.0" rim widths, so they suit most compact riding mowers and lawn tractors that accept that rim size.

• Match the sidewall stamp: 18x8.50-8
• Designed for 7" rims; 8.2" section width
• Outer diameter ~17.75" (455 mm) for correct clearance
• Sold as a pair; wheels not included

How does the tread and construction affect performance on turf?

The tire's 7.1 mm (0.28") groove depth and diamond-cut tread edges help shed mud and small stones while minimizing turf damage. A pronounced shoulder pattern provides 360° traction for uneven ground without relying on aggressive lugs that tear grass.

• Deeper grooves improve water evacuation on wet grass
• Diamond-cut edges prevent stone retention and aid cleaning
• Shoulder tread balances grip and turf preservation
• 4-ply carcass offers strength without excessive turf compaction

What load, speed, and noise characteristics should I expect?

These tires carry a maximum load of 815 lbs at 22 PSI per tire and use a 4-ply rating (Load Range B) for robustness on garden equipment. YINTATECH’s 3D polishing process aligns tread blocks to reduce vibration and lower running noise compared to basic replacement tires.

• Max load: 815 lbs (per tire) at 22 PSI
• 4-ply rated carcass with 2-ply sidewall reinforcement
• Quieter operation via tread polishing and balanced design
• Not intended for sustained highway speeds or road-only use

How do I install and maintain these tubeless tires?

As tubeless tires they mount directly to compatible rims and require proper seating and inflation. Regularly inspect tread depth, sidewalls, and rim fit; maintain the recommended pressure for load carrying and even wear.

• Mount onto a 7.0" compatible rim — professional mounting recommended
• Inflate to specified pressure for load and handling consistency
• Check for cuts, punctures or embedded debris periodically
• Store off-season in a cool, dry, shaded location away from ozone sources

Who is this for: The YINTATECH 18x8.5-8 set of two tubeless tires is aimed at homeowners and landscapers who need a robust, turf-friendly replacement for riding mowers, lawn tractors and garden tractors that accept 7" rims. If you want improved traction, better mud-shedding ability, quieter operation, and a higher load capacity than many economy tires, these deliver a practical balance of traction and turf care. Confirm your mower’s sidewall sizing and rim width before ordering; contact the YINTATECH support team if you need fitment help.
