Oval Tyre 21x9 (4pcs)

Mitoos Oval Tyres 21x9: precision in every curve

When tyres age or lose section, the car loses contact with the track and lap times noticeably worsen. These Mitoos Oval tyres in size 21x9 allow you to restore the original grip of your model without complications, with consistent measurements across the 4 pieces in the pack for balanced mounting on both axles.

Features and Highlights

• Size: 21x9 (diameter x width in mm)
• Oval profile, which favours a progressive contact patch and predictable behaviour both on straights and in corners
• Pack of 4 pieces, sufficient to equip a complete set of wheels for a car or have spare parts ready for the next session
• Mitoos reference: CXM090

Function and Performance

The oval profile of these tyres distributes contact pressure evenly, resulting in homogeneous traction on plastic, wood, or cork surfaces. By maintaining a constant diameter across the four pieces in the pack, imbalance between wheels on the same axle is minimised, a detail that makes a real difference in the behaviour of club-prepared cars.

Mounting and Preparation

Mounting is done like any standard slot tyre: it is seated on the corresponding rim and, if necessary, machined around the rims to precisely equalise the final diameter. It is recommended to check that all four pieces have the same diameter before mounting; in case of small differences, machining allows for easy correction.

Compatibility

As this is a specific size tyre (21x9), its compatibility depends on the rim of the model in question. Check the rim measurements of your car before ordering to ensure the fit will be correct. Mitoos is a common brand in 1/32 scale slot cars and spare parts.

Ideal for…

• Preparers looking to replace tyres with sizes faithful to the original
• Club enthusiasts who want to always have a spare set on hand
• Any model that uses rims compatible with the size 21x9

Frequently Asked Questions

How many tyres are included in the pack?

The pack contains 4 pieces, allowing you to equip a complete car or keep a pair of spares ready for the next race.

Do I need to machine these tyres before using them?

It is not mandatory, but it is advisable if you are looking for maximum performance. Machining equalises the diameter of the four pieces and ensures perfect contact with the track from the first lap.

Which cars are these tyres compatible with?

Compatibility depends on the rim of each model. The size 21x9 is common in several 1/32 scale cars, but we advise you to check the dimensions of your car's rim before confirming your order.

Can they be used on wooden and plastic tracks?

Yes. The oval profile adapts well to both surfaces, although the final level of grip will also depend on the tyre compound and the condition of the track.
