For the Belgium GP its not allowed to cut off rows on the tire so it will be low profile. It takes about 1 sec off the laptimes with low profile. Then we are taking 2wd front tires in front on the 4wd, and front 4wd tires in rear on the 4wd. Its wery hard to glue!!!! Use strong tape to do it.
Im from denmark so hope Im understandable
