B/F Tire Advise needed, Buggy = Extreme Apexx. Sand conditions all, soft dry, soft wet, wet hard.
Which tire brand and model?
Are ribs or grooves needed?
Are inner tubes needed?
Should Slime be used to prevent deflation?
Which rim is adequate?
What air pressure on different conditions?
Can I run Midi front B/F rear?
If I missed any questions feel free to comment.
Thanks, Randy

Most of the Apexx crew is busy at SOBB .

Standard bigfoot or Kenda beach racers seem the choices?

in europe we use mainly eurotrax or duro tires on cadkat rims for competition. but i dont know how this stuff is available oversee... libre dealers could be a good point of contact.

the trax tires offer a wide range of pressure they can be driven with. low psi for wide contact area on soft sand, high psi for hard surfaces.
duro tires save some weight (rotating mass is a crucial point in every sport with wheels), but offer a bit less contact area.

cadcat rims are light and have the advantage to be 2 part design. a defect ballbearing can destroy the bush it sits in. with one pice rims you have to buy a complete new rim, cadkats just need a new insert.

grooves are handcut, between 11 and 17 grooves per wheel are standard.

mostly the wheels are tubeless but if u have very very soft sand tubes can be handy to lower the psi to a min.

when water stands on the beach disk wheels come in handy as you dont get aquaplaning. landsegler.de builds some high end stuff special for buggys. they even have some wider diskwheels that offer a contact area similar to big foot weels... extrem slick look these toys but not cheap...

midi wheels are manly used on hard grassland or tarmac.

kenda wheels arent used in racing due to the fact that they are heavier (slower) and the rubber is stiffer (doesnt give the same grip as the trax or duro tire covers).
but as kendas are cheaper they are a good deal if max. perfomance is not the main target plus they will last a lot longer due to the harder rubber.

mixing tires (bf light front, bf full rear) can be done but u have to look out that u dont screw the balancing of your buggy. to much grip on the rear and not enough on the front can be dangerous in emergency situations - say u want to make a emergency stop, and your buggy just slides uncontrollable over the front wheel instead of drifting over all wheels to kill speed.

Thanks for the details, much appreciated. Randy
