5.50 Hoosier on the left rear. Easy enough to get there with the 5.50...the 6.50 will roll out too close to 34" even on a wide lr wheel.
For this reason, we often run 6.50 right sides and 5.50 left sides to get the sizes of treads back to what they should be for a flat kart.
Using a wide tire on the left rear will make the car push like a truck center-off or when you're on the throttle. If you decide to go that route, you'll probably end up on stupid low cross (even negative - ie 48%) to make that deal work.
Personally, I'd run the smaller tires I described and a lot of your set-up woes will go away as you can go back to a normal flat kart set-up like you run with slicks.

I have a new set, that have the desired stagger. But the RR is 37 1/4". From what I've been reading thats way too big for a red plate clone. Or even any restricted clone. So I wanted to get all four tires down in size to save weight and rolling resistance.The stagger you desire is easy to get. But having a 34" RR might not be? Id buy the 12x9.00x6 for the RR and a 11x7.1x5 for the LR. Then gear accordingly for the larger right rear.
Exactly. Those tires were designed for the 250 & 500 cc winged outlaw karts that can bust the tires loose and throwing rooster tails of race track in the air at will.I have a new set, that have the desired stagger.
