Maxxis 3C Triple Compound mountain technology uses a harder, longer lasting base layer and two progressively softer top layers in order to optimise traction and stability. 3C Maxx Terra Compound Maxx Terra is an intermediate compound configuration used in select mountain bike tyres. It is softer and offers more traction than their 3C Maxx Speed, yet provides better treadwear and less rolling resistance than their Maxx Grip. EXO Protection Technology An extremely cut-resistant and abrasion-resistant material added to the sidewalls of select mountain tyres. This densely woven fabric is also lightweight and highly flexible, ensuring that the performance of the tyre remains unaffected. Choose EXO Protection for exceptionally rocky, treacherous trails where the chance of sidewall cuts and abrasions is high. TR (Tubeless Ready) Technology Tubeless tyres provide the rider with many benefits: the ability to run lower air pressures, which improves traction; lower rolling resistance when compared to a tube-type tyre; and less chance of flatting since there is no tube. Maxxis Tubeless Ready (TR) tyres provide the benefits of a UST tubeless tyre without the weight penalty. Their TR tyres use a standard casing and require the use of a liquid sealant in order to make them airtight. Maxxis Tubeless Ready tyres are the only Maxxis tyres approved for use with liquid sealants.
