For a Good Time AND a Long Time
Keeping air in your tires is a crucial part of any ride – we take several approaches to protecting your tires from road debris and sharp objects working through the tread. To improve durability in rocky terrain where casing pinches can ruin a great day, we reinforce casings to resist cuts through the tire sidewall or bead.
If you need clarification or advice about which tire is for you, always feel free to ask questions at info@challengetires.us
Puncture

Protection

PPS
PUNCTURE PROTECTION SYSTEM
PPS is a tough, tightly-woven fabric placed between the tread and casing to increase puncture resistance. PPS is light and doesn't affect ride quality so we include it in almost every tire.

PPS2
2X PUNCTURE PROTECTION
Our tires designed for use on rough roads, cobbles and gravel are built with an additional layer of PPS (PPS2) on the inside of the casing. This second layer adds a bit of weight so we apply it to tires that see rougher conditions - Our entire Gavel line, for instance.
Reinforced

Casings

Silver Armor
CORAZZA (Armor, in Italian) SILVER
Corazza Silver is double-layer casing reinforcement applied internally from tread to bead that improves resistance to sidewall cuts and punctures that can occur on bad pavement or rough roads.
WHICH TIRES?
Silver reinforcement is used in all our Gravel PRO Series tires including Strada Bianca if you're looking for a tougher Road tire option in 30C or larger.

Gold Armor
CORAZZA GOLD
Corazza Gold combines the Corazza Silver internal sidewall reinforcement with an additional bead-to-bead layer of tightly woven material reinforcing the entire casing.
WHICH TIRES?
Our XP Series Gravel tires receive this extra boost of protection – if you need maximum protection from sharp rocks and bead strikes, they should be just the ticket.
