The RT-2012 set is the one you will need to build the car last raced to victory by Ronnie Peterson before his untimely passing at the Italian GP in Monza, 1978.
The RT-2012 set fits both the Hasegawa and Tamiya Lotus 79 kits. The set features the 1978 Wingfoot tread pattern similar to that of tire set #RT-2002. The set includes 4 rain tires (2 fronts & 2 rears) and decals for the tires.

All of Icon Automotive Miniatures 1/20th scale tire sets are designed to fit Tamiya Plastic models first. Often times the kit wheels of another plastic model kit manufacture will work with only small modifications. The same can be said for Model Factory Hiro, Studio-27 and other Multi-Media kits. If you are unsure as to whether any of these tire sets would be correct for the model you are building feel free to contact us at: firstname.lastname@example.org and we will do our best to answer your specific questions.
