What tire size does the Cub Cadet CC30H use?
The Cub Cadet CC30H uses 13 x 5 – 6 front tires and 16 x 6.5 – 8 rear tires. The recommended operating tire pressure is approximately 14 psi in the front tires and 10 psi in the rear tires. The factory tread style is listed as Turf Saver.
Cub Cadet CC30H Tire Size: 13×5-6 Front / 16×6.5-8 Rear
The Cub Cadet CC30H uses Turf Saver lawn tires with about 14 psi front pressure and 10 psi rear pressure.
Best simple answer: buy 13×5-6 front tires and 16×6.5-8 rear tires for the Cub Cadet CC30H. Use Turf Saver or turf-style replacements and set pressure close to 14 psi front and 10 psi rear.
Cub Cadet CC30H Tire Pressure
The Cub Cadet CC30H operator manual lists the recommended operating tire pressure as approximately 14 psi for the front tires and approximately 10 psi for the rear tires. Keep both tires on the same axle equal. Uneven tire pressure can cause uneven cutting, steering pull, poor traction, and deck-level problems.
Tire Position
Recommended Pressure
Why It Matters
Front Tires
About 14 psi
Supports steering response and keeps the front of the mower sitting correctly.
Rear Tires
About 10 psi
Helps traction, ride comfort, and lawn protection.
Left-to-Right Pressure
Keep equal
Unequal pressure can make the mower cut unevenly.
Maximum Pressure
Do not exceed tire sidewall maximum
The manual says to refer to the tire sidewall and not overinflate.
Blunt verdict: do not inflate CC30H tires like car tires. These mower tires run low pressure on purpose. Overinflation can make the mower ride rough, lose traction, scalp grass, and cut unevenly.
How to Read the Cub Cadet CC30H Tire Size
The CC30H tire sizes use standard lawn and garden tire sizing. For example, 16×6.5-8 means the tire is about 16 inches tall, about 6.5 inches wide, and fits an 8 inch rim.

Best Replacement Tires for a Cub Cadet CC30H
The best replacement tires for a Cub Cadet CC30H are Turf Saver or turf-style lawn tires in the original sizes. Stay with 13×5-6 front and 16×6.5-8 rear unless you have a specific fitment reason to change, because tire height affects deck level, steering, traction, and mower clearance.
Replacement Target
Recommended Spec
Why It Matters
Front replacement tire
13×5-6 turf tire
Matches the original front steering tire size.
Rear replacement tire
16×6.5-8 turf tire
Matches the original rear drive tire size.
Tread type
Turf Saver / turf tread
Protects grass better than aggressive lug tires.
Load rating
Equal or better than original tire
A weak tire can squat, leak, or wear poorly.
Overall diameter
Stay close to stock
Changing tire height can affect deck leveling and cut quality.
Valve stem
Replace if old, cracked, or leaking
A bad valve stem can make a new tire lose air.
Owner tip: if your CC30H cuts unevenly after replacing tires, check tire pressure before touching the deck adjustment. A few psi difference side-to-side can make the mower look badly out of level.
Front Tires: Cub Cadet CC30H 13×5-6
The front tires on the Cub Cadet CC30H are 13×5-6. These are the steering tires, so correct size and pressure matter for steering feel, turning response, and front deck height.
Correct Front Tire
13×5-6
Use this size for proper steering height, front deck position, and stock fitment.
Wrong Front Tire
Avoid
A taller or shorter front tire can change the mower deck angle and affect cut quality.
Rear Tires: Cub Cadet CC30H 16×6.5-8
The rear tires on the Cub Cadet CC30H are 16×6.5-8. These are the drive tires, so they matter most for traction, hill grip, and keeping the mower moving without tearing up grass.
Correct Rear Tire
16×6.5-8
Use this size to maintain correct rear ride height, drive behavior, and deck level.
Wrong Rear Tire
Avoid
Oversized rear tires can affect clearance. Undersized rear tires can lower the mower and change the cut.

Are Cub Cadet CC30H Tires Tubeless?
Most replacement lawn tractor tires in the CC30H sizes are commonly sold as tubeless turf tires, but the practical answer is to match the tire marking and rim condition. If the rim is clean and seals properly, tubeless is usually the cleaner setup. If the bead leaks or the rim is rusty, an inner tube can be used as a repair option.
Setup
When It Makes Sense
Tubeless tire
Best when the rim is clean, straight, and seals properly.
Tire with tube
Useful when the rim leaks, the bead will not seal, or the tire loses air slowly.
Foam-filled tire
Usually overkill for a small rear-engine mower and can make the ride harsh.
Turf Tires vs Aggressive Tires on a CC30H
For most CC30H owners, turf tires are the right move. The CC30H is a compact rear-engine riding mower built for lawn mowing, not mud work. Aggressive lug tires may help on slopes or wet ground, but they can mark grass faster and may affect ride comfort.
Best Choice
Turf Saver or turf-style tires in 13×5-6 front and 16×6.5-8 rear. Best for normal lawns and clean cutting.
Maybe
More aggressive rear tread if you regularly mow mild slopes or damp grass and accept more lawn marking.
Avoid
Oversized tires, ATV-style lugs, mismatched left/right tires, or anything that rubs the mower frame or deck.
Cub Cadet CC30H Tire Chains
Tire chains are usually fitted to the rear drive tires. Since the CC30H rear tire size is 16×6.5-8, chains need to match that tire size. Tire chains can help with snow, ice, or poor traction, but they are not usually needed for normal mowing.

Common CC30H Tire Problems
Problem
Likely Cause
Fix
Uneven cut
Unequal tire pressure, worn tires, or deck out of level
Set tire pressure first, then level the deck.
Rough ride
Overinflated tires
Reduce pressure to the recommended range, staying within sidewall limits.
Poor traction
Worn rear tires, wet grass, low pressure, or slick turf
Check rear tire tread and pressure.
Slow leak
Leaky valve stem, bead leak, puncture, or rusty rim
Inspect tire, valve, bead, and rim; tube may help.
Steering feels heavy
Low front tire pressure
Set front tires close to 14 psi.
Mower pulls to one side
Unequal tire pressure or uneven rear traction
Match left/right pressure and inspect tires.
Real-world fix: before blaming the deck, transmission, steering, or blades, check tire pressure. On small riders like the CC30H, wrong tire pressure can make the whole mower feel off.
