RU-1432-2 14x32 Drag Slicks Tire ID is designed to work with earlier 1/25th scale wheels. These slicks replicate the popular 14x32-15 drag slicks used on lots of higher horsepower cars of today and was the standard tire used for 70s and 80s vintage Pro Stock, Gas Glass, Modified Production, and faster Super Stockers. These tires are designed to fit a scale 15" wheel. Tire OD is ~1.31". Sidewall width is ~.750". Tread width is ~.625". They were redesigned, with the use of 3D modeling to improve their appearance and realism. The recess around the ID of these slicks was removed so there is a cleaner fit with the wheel and the method of molding has reduced venting to almost nothing, so the tread surface is greatly improved where vented. Scuff the tread surface to eliminate the mold line and they're ready to install! Soft rubber. One Pair.
