Autocross this weekend and first time on new Toyo R1R's. Suggestions as to starting pressures, front and rear? (225 16's) 2005 S, bone stock suspension. Autocrossed fairly seriously for about 10 years but just 3 events in front wheel drive on new to me Mini!! (on 10 yr old tires from previous car.....) Do I need to spray them between runs? Have read that they lose grip fairly quickly. Sorry if Toyo, pressure covered somewhere on another thread but could not find. Thanks for any help!
