Introducing the new IRC Formula Pro X Guard TL tyre. By using a bead to bead 40x40tpi mesh puncture-resistant guard, we have achieved amazing puncture-resistant performance. By adding a new RBCC to the strongest road tubeless tyre that is also strong against cuts, you have the holy grail a hard wearing tyre that is puncture resistant and extremelly grippy especially in the wet.

The new RBCC is used in all FORMULA PRO series products. This tyre

The RBCC, which is loved by many for its firm grip through the bends and in wet conditions, has been used in all tyres in this series. While rolling resistance is reduced, while grip and abrasion resistance have been improved. 

Redesigned tread with a pattern that emphasizes controllability

Tread pattern to enhance 

Continuing from the previous tyre this time the center has adopted the Sugime pattern. The behavior near the limit, such as the start of tire slippage, is easier to spot and therefore more controllable. In addition, rolling resistance was reduced by adding four grooves in the circumferential direction, and the tyre is more are on uneven road surfaces as a result.

Latex lining

The Formula Pro RBCC  tyres use a latex lining covering the inside of the tyre. This lining reduces air leakage and make the casing . Essentially the tyre  it self does not require sealant to seal it, but the rim tyre interface often does. 

Compatible with disc brakes and wide rims

The tubeless tire, which has a structure in which the tire bead is pressed against the rim from the inside with air to retain air, is characterized by high safety due to the high degree of adhesion between the rim and the tire, but with the new FORMULA PRO series, the key is Further strengthening around the bead. We have succeeded in further improving safety so that it can withstand the stronger force applied by the disc brakes and pothole impacts. In accordance with the tubeless rim standards reviewed in 2019, it is also compatible with wide rims.


The Formula Pro series tyres unlike many other brands run true to size on a 19mm internal width rims which are used on our BORG series road wheels. 25mm tyres inflate to 25mm wide and 22mm tall. 28mm tyres are 28mm wide and 24mm tall. 30mm tyres are 30mm wide and just over 25mm tall.

25mm tyre is 300g, 28mm tyre is 340g and 30mm tyre is 370g. 

80psi is the suggested max pressure. IRC state a max pressure of the sidewalls which half the max pressure at which blow off occurs in tests. I.e 90 to 115 psi means blow off occurs at 180 to 230 psi. Hense my max suggested pressure. 60 to 80 psi works well for most people.

COVID 19 update. Overseas shipping is now with a courier only. UPS or Parcel force.

U.K policy

Orders placed in the afternoon normally get sent the next workday where possible. Orders placed before noon are often sent the same day but this is not guaranteed. Priority is given to Royal Mail Special delivery items always. 

Same day disptach is not guaranteed due to volume of mail order. In general we are not operating with big delays in dispatch if any.

  • Standard shipping is with Royal Mail using there 24 service. Cost £3. This is not a guaranteed service and takes 1-7 days normally but can be longer. The tracking number is not tracking but is a conformation of delivery code. If the item has been delivered to you or a neighbour then the tracking shows something otherwise it won't. If the item is needed urgently then pay for the courier/special delivery. in the case of the items recorded as delivered but you claim non delivery or delivery attempted but parcel never available for collection no refund or replacement goods are possible. R24 is not a tracked or insured service. We are only liable if delivery never happens. We wait 30 days before declaring am item lost. If this is not acceptable to you then pay for Special Delivery which is tracked and insured. We are not longer taking the hit for lost items because you want to spend less on postage. 
  • For a £7 surcharge, a next day (not sunday) tracked service (from dispatch) with Royal mail special delivery is used. You get an hour delivery slot by text. It's a fine service and worth the money. This only works for items up to 2kg. beyond that it gets very expensive and Parcel Force 24 tracked is used. This is fully insured service so in the event of non delivery a claim is possible.
  • Rims are sent by courier only- cost £10. UPS is used. A phone number and email address must be supplied to allow me to book in. This service can also be picked for smaller items that you want delivered by UPS.

Due to the disruption in postal services during 2020, misdeliveries, customs issues and long delays all overseas shipping is now with Royal Mail International Tracked and Signed (europe only) and  UPS or Parcel Force tracked services. Parcel mass and destination affect price. So the following applies. I do not offer cheaper slower mail services anymore.
