Does the R4FT need a tube?

Yes. It is a tube-type tire, so fit an inner tube. Tubes come only with the two-pack option.

Is it tubeless-ready?

No. The folding wire bead and casing are designed for use with a tube.

What is the maximum pressure?

30 PSI. Stay at or below that; lower pressure gives more grip and cushion on sand and snow.

Will it fit my e-bike?

It fits rims and frames built for 20x4 or 26x4 fat tires. Check your frame clearance before ordering.

How does it compare with premium fat tires?

It costs less and resists punctures well, but the 30 TPI casing is firmer and heavier than higher-TPI premium tires.

Where is the R4FT cheapest?

At Hycline, for $107.99, as of our latest check.
