I run maxxis high rollers or minions, pressures depend on what size tire your running, and the track, if it was a short pedally track, like ipswich for S.E. Qlder's id go something like a 2.5 High roller front, maybe even a single ply on the front for lighter weight, pressure at about 22psi rear go for a high roller 2.35 at about 24 psi, maybe go up a couple if im worried about a flat in a spot.
but preety much everywhere else id run a 2.7 minion on the front, ive found then to be a little better than the high rollers, uaually always run the bigger tires, despite what people say the extra weight and rolling resistance is such a small difference and u get more grip for sure, but thats just me, some people prefer smaller tires in soft conditions to cut thru the dirt, but with a 2.7 im run about 20 psi front and a 2.5 back at about 24 again.
Tire pressures and type always depend on the conditions, the dirt, the track, lats of things , u should really go and experiment and see what works for you, try super hard , super soft and just see what happens, i wouldnt go below 15 psi though, thats just scary when th etire starts to roll, or worse, roll off.
After ive said all this id recomend a 2.7 and 2.5 super tacky minions front and rear, a front minion on the rear is also really good, u can run the slow reezays if u want but they do wear out super fast, but traction is unreal, im just talking about maxxis here tho cause that seems to be the best option, value for money is trhe bvest here, but ive run other before, like intense and michelins and the same pressures seem to work for all tires
just go and experiment, but with the optios i mentioned u really cant go wrong
