So I will be making a trip to the sand dunes for a ATV trip with some friends. I want to take my Mamba E-revo. I want to purchase sand tires. but wanted to know should I just run paddle tires on the rear or run paddle tires on all 4 four corners? I will be running 6s. will be hitting up a ton of big steep hills. thanks for any info. never had a R/C on sand.
