AR-PRO 20x8.00-8 Rear Tire and Wheel Assembly, 4-Ply Tubeless Turf Tire with 3/4" Borehole, 3.5" Offset Hub, 3/16" Keyway – Compatible with John Deere Riding Lawn Mowers & Garden Tractors

What It Is

This is a complete rear tire and wheel assembly for riding lawn mowers and garden tractors, specifically designed to replace worn or damaged turf tires. The 20x8.00-8 size, 4-ply tubeless construction, and 3/4" bore with 3.5" offset hub make it a direct fit for many John Deere models requiring a high-flotation rear tire.

Fitment & Compatibility

Before buying, check these three things:

• Bore size & keyway: The 3/4" bore and 3/16" keyway must match your axle. Measure your axle diameter and key slot width—most John Deere garden tractors use this, but verify.
• Offset: The 3.5" offset (distance from hub mounting face to wheel centerline) affects tire clearance against the frame and deck. Measure your current wheel’s offset; mismatched offset can cause rubbing or poor tracking.
• Tire size: 20x8.00-8 is common on John Deere X300, X500, and older 100-series riders. However, some models use 20x10.00-8 or 18x8.50-8. Confirm your current tire size stamped on the sidewall.

OEM cross-reference numbers include John Deere AM107714, AM130361, and AM141176. This is an aftermarket replacement, not OEM—quality is high, but check warranty terms.

Key Things to Know

• Installation difficulty: Easy—remove axle nut, pull old wheel, slide on new one, tighten nut to 35-45 ft-lbs. No special tools needed.
• 4-ply rating: Good for residential use on turf, but not heavy-duty for commercial mowing or rocky terrain. Expect reasonable puncture resistance.
• Tubeless design: No inner tube to replace or adjust, but the bead must seat properly. If you have a tube-type rim, this won’t work.
• Common gotcha: The 3/16" keyway is standard, but some older John Deere models use a 1/4" keyway. Measure your key slot width before ordering.

Should You Buy It

Yes, if you own a compatible John Deere garden tractor or riding mower with a 3/4" axle and need a reliable, affordable replacement rear tire assembly. It’s a straightforward swap for worn-out turf tires and offers good value compared to OEM pricing. Not ideal if you need a heavy-duty tire for rough terrain or have an oddball axle size.
