Maxxis Tubeless Ready (TR) tyres provide the benefits of a UST tubeless tyre without the weight penalty. Our TR tyres use a standard casing and require the use of a liquid sealant in order to make them airtight..EXO: 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..
