Hi Mate, Like morrjr71 said they don't hook up. I bought a Muraco and first drive on grass and a bit of dirt was absolutely horrible essentially was like driving on ice .. I honestly can't believe Corally would choose them to sell the car with they're that bad.. That's when I seen Popalong RC's video on YT and they ran Truggy racing wheels/tyres so I got some Louise T Pirates and the transformation was incredible and now the Muraco is a weapon when I'm racing around with my mates.
I have an Asuga as well and like you have been looking at tyre/wheel options. I ran the SKETER wheels which were good-right OD too... .. I seen a post on here the other day where the guy has the wheels/tyres off the 6S Mojave ,Fortress I think they are, and he loves them. They're a good size in terms of outside diameter. I think I'm going to give them a try next .. I'd love to put the PIRATE racing tyres on it but the slight increase in OD means the shock will bottom out internally before the chassis does on the ground leading to damage/early failure of the shock.. I'm not a jumper hard basher ( we set up tracks and race around) but still won't risk the damage.
