It depends on your motor and the track. In the 1/10 2WD truck class, racers gear by final drive ratio: 7.5–8.5T near 10.14, 13.5T near 8.27. On the 22T 4.0's stock 82T spur that is about 20T for 7.5–8.5T, 24T for 13.5T. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the 22T 4.0 selected.
What is the internal ratio (transmission ratio) of the TLR 22T 4.0?
The 22T 4.0 has an internal ratio of 2.43:1. Final drive ratio = spur ÷ pinion × 2.43. With the stock 82T spur, a 16T pinion gives an FDR of 12.45 and a 30T gives 6.64.
How many teeth is the stock spur gear on the TLR 22T 4.0?
82 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.

What shock oil does the TLR 22T 4.0 come with?
Out of the box the 22T 4.0 runs 32.5 wt front, 32.5 wt rear (Team Losi oil), on 2 x 1.6mm (#233009) front, 2 x 1.7mm (#233010) rear pistons. That is the kit setup; you will need to adjust it for your track conditions. The RC Setup App can help dial it in.
What springs does the TLR 22T 4.0 come with?
The kit springs are Blue (#5183) front, Yellow (#5167) rear. Stiffer springs suit high grip and big jumps; softer springs add grip on slick or bumpy tracks.
