They aren't bad for what you pay, but any of the RC4WD are better. They just don't have much 'squish' compared to stock or the RC4WD's. But they are more 'grippy' than stock tires. As far as size goes, they are between stock Beadbolt/Jeep and C10 tires. (See photo.) They are nice and wide though and I do like the pattern better than stock. (They are the same width as Betty tires.) Like I said, good, not great, but I will use them just to have something different.
