Genuine HT spare/option part. Extra wide tire mounted and glued on genuine 1/6 scale FG Stadium Truck rims 6232/01.Diameter 165 mm, width 90 mm. Fits all FG and Carson largescale cars, may fit other cars with 18 mm wheel squares as well.Available in three different compounds:SoftMediumHardWe have tried various rubber / tire compounds for several months on various forms of terrain, etc.. The Mammoth brings, due to its quite strong and large pins and the extreme width of the tire, especially on hard and low grip surfaces a high traction! The Mammoth is available in soft, medium and hard! The rule is: the harder the ground the softer the tire compound. Where other tires spin helplessly the Mammoth provides serious traction. The disadvantage of Mammoth tires: Because of their extreme width they need to be mounted on FG wheels, which is a labor intensive job. From experience, we must strongly recommend against using rims from another manufacturer in combination with extension rings. Due to the before mentioned traction no other rim has been up to the task! Broken rims and torn squares were the result. Due to the high torque load on the bonding of tires on largescale cars, checking the bonding from time to time and re-glueing (y0067) if necessary is unavoidable.However, the original FG-rim lasts without problems!Unit prices:Mammoth tires extra wide: 47,20 EUR / pairMammoth inserts extra wide: 9,70 EUR/ pairGenuine FG wide track rims 6232/01: 29,90 EUR / pairMounting + glueing rims / inserts / tires: 13,00 EURTotal: 99,80 EUR Contents:2 piecesAlso suitable for:With the following wheel adapter: y1183 Rim adapter
